e. Perpetual inventory system ▶
Absorption Costing
Absorption costing is a method used in managerial and financial accounting to determine the total cost of a product by including both variable and fixed manufacturing costs. In this approach, all production costs such as direct materials, direct labor, and both variable and fixed manufacturing overheads are absorbed into the cost of the product. This means that every unit produced carries a portion of all costs incurred during production. The concept is based on the idea that production cannot occur without incurring both types of costs, therefore they should all be included when calculating the cost per unit. Absorption costing is also known as full costing and is required for external financial reporting under accounting standards like IFRS and GAAP.
For example, consider a company that manufactures wooden tables. The direct material cost for each table is Rs. 500, direct labor cost is Rs. 300, variable overhead cost is Rs. 100 per unit, and total fixed overheads amount to Rs. 50,000 for a production of 1,000 tables. The fixed overhead per unit would be Rs. 50 (calculated as Rs. 50,000 ÷ 1,000 units). Therefore, the total cost per table under absorption costing would be Rs. 500 + Rs. 300 + Rs. 100 + Rs. 50 = Rs. 950. This cost represents the complete cost of production, which includes both variable and fixed elements. This method ensures that inventory valuation on the balance sheet includes all manufacturing costs and that the cost of goods sold in the income statement reflects total production cost.
Conversion Cost
Conversion cost refers to the total cost required to convert raw materials into finished goods. It is the sum of direct labor costs and manufacturing overheads, excluding direct materials. The purpose of this concept is to measure the efficiency of the production process in transforming materials into final products. Since direct materials represent the physical input and conversion costs represent the transformation effort, the term highlights the human and mechanical resources used during manufacturing.
Mathematically, conversion cost can be expressed as:
\[
\text{Conversion Cost} = \text{Direct Labor} + \text{Manufacturing Overheads}
\]
For example, assume a company producing shirts spends Rs. 100,000 on direct labor and Rs. 60,000 on manufacturing overheads in a given month. The conversion cost for that month would be Rs. 160,000. This figure shows how much it costs the company to convert fabric (the raw material) into finished shirts. Conversion cost is especially useful in process costing systems where products pass through multiple stages. Managers often analyze conversion cost per equivalent unit to assess production efficiency, control costs, and make informed pricing decisions. Reducing conversion cost through improved technology, training, or process automation can enhance profitability and competitive advantage for manufacturing firms.
Semi Variable Cost
A semi-variable cost, also known as a mixed cost, is a cost that contains both fixed and variable components. The fixed portion remains constant regardless of the level of activity, while the variable portion changes in direct proportion to changes in production volume or service activity. This type of cost behaves partly like a fixed cost and partly like a variable cost, making it an important concept in cost analysis and decision-making.
For instance, consider the electricity cost of a manufacturing plant. The company might pay a fixed monthly charge of Rs. 10,000 just for being connected to the electricity supply, plus Rs. 5 per unit of electricity consumed. If the plant produces more goods, the electricity consumption increases, thereby increasing the total cost. However, even if production stops temporarily, the company still pays the Rs. 10,000 fixed portion. Thus, the total electricity cost can be expressed as:
\[
\text{Total Cost} = \text{Fixed Cost} + (\text{Variable Cost per Unit} \times \text{Activity Level})
\]
In this example, if 4,000 units of electricity are used, total cost would be \(10,000 + (5 \times 4,000) = Rs. 30,000\). Understanding semi-variable costs helps managers in budgeting and forecasting because it allows them to estimate costs more accurately across different activity levels. It also aids in break-even analysis and cost control, as separating fixed and variable portions makes it easier to predict cost behavior when production volume changes.
Manufacturing Cycle
The manufacturing cycle, also known as the production cycle or operating cycle, refers to the time period between the start of production and the completion of finished goods. It includes all activities that transform raw materials into final products ready for sale. The length and efficiency of the manufacturing cycle play a crucial role in determining production capacity, inventory management, and overall profitability. A shorter cycle time means faster turnover of inventory and better utilization of resources.
Typically, the manufacturing cycle includes several stages: purchasing and receiving raw materials, processing and assembly, quality inspection, and storage of finished goods. For example, a company producing mobile phones might begin its manufacturing cycle when it purchases electronic components such as chips and screens. These materials are then assembled into phones, tested for quality, and packaged for sale. If the company takes 10 days to procure materials, 15 days to assemble, 2 days for inspection, and 3 days for packaging, the total manufacturing cycle is 30 days.
In management accounting, the manufacturing cycle time can be calculated as:
\[
\text{Manufacturing Cycle Time} = \text{Process Time} + \text{Inspection Time} + \text{Move Time} + \text{Wait Time}
\]
Improving the manufacturing cycle is a major focus of lean manufacturing and just-in-time (JIT) systems. Companies aim to minimize non-value-added activities such as waiting and movement, which do not directly contribute to product creation. Efficient cycle management leads to reduced costs, faster customer delivery, and better competitiveness in the market.
Perpetual Inventory System
A perpetual inventory system is an inventory management method in which inventory records are continuously updated with every purchase and sale transaction. Unlike the periodic inventory system, which updates inventory balances at specific intervals, the perpetual system maintains real-time information about the quantity and value of inventory on hand. This is achieved through computerized systems that automatically record data whenever goods are received, issued, or sold.
For example, when a retail store sells a product through its point-of-sale system, the inventory count for that product decreases instantly while the cost of goods sold is recorded simultaneously. Similarly, when new stock arrives, the system updates the purchase and adds it to available inventory. This method provides accurate and immediate data on stock levels, enabling better inventory control and decision-making.
The perpetual inventory system has several advantages. It allows companies to identify stock shortages or surpluses quickly, reduces the risk of stockouts, and supports efficient reorder management. It also helps in detecting theft or loss, as discrepancies between physical and recorded inventory can be identified at any time. For instance, if a company’s system shows 1,000 units in stock but a physical count reveals only 980, management can investigate and take corrective action.
In addition, perpetual systems support integration with other business processes such as accounting, purchasing, and sales. Modern enterprise resource planning (ERP) systems rely heavily on perpetual inventory tracking for accurate financial reporting. However, while highly efficient, the system requires reliable data input and periodic physical verification to ensure that recorded figures match actual inventory. Overall, a perpetual inventory system provides transparency, improves control, and enhances decision-making by offering up-to-date and accurate inventory information at all times.

Inventory Management and Control Levels
Organizations maintain several inventory control levels to ensure continuous production while minimizing costs. These levels help determine when to order materials, how much to order, and when stock levels become critical. Proper inventory management balances holding costs with stock-out risks and supports smooth business operations.
Ordering Level
The ordering level, also known as the reorder level, is the point at which a new purchase order should be placed to replenish inventory before it runs out. It is calculated by considering the average consumption rate and the lead time required to receive the materials after placing an order. The formula is usually expressed as:
\[
\text{Reorder Level} = \text{Maximum Consumption} \times \text{Maximum Lead Time}
\]
For example, if a company consumes 200 units per week and the maximum delivery time is 3 weeks, then the reorder level is \(200 \times 3 = 600\) units. When the inventory level falls to 600 units, a new order should be placed to ensure materials arrive before stock depletion.
Maximum Level
The maximum level is the highest quantity of inventory that should be kept on hand to avoid excessive storage costs and the risk of material obsolescence. Keeping stock beyond this point results in unnecessary capital blockage. The formula for maximum level is:
\[
\text{Maximum Level} = \text{Reorder Level} + \text{Reorder Quantity} - (\text{Minimum Consumption} \times \text{Minimum Lead Time})
\]
For example, if the reorder level is 600 units, the reorder quantity is 400 units, the minimum consumption is 150 units, and the minimum lead time is 2 weeks, then:
\[
\text{Maximum Level} = 600 + 400 - (150 \times 2) = 700 \text{ units.}
\]
This means the inventory should not exceed 700 units at any time.
Minimum Level
The minimum level indicates the lowest quantity of inventory that should be maintained in stock to prevent a production stoppage. If stock falls below this level, there is a danger of running out of materials before new supplies arrive. The formula is:
\[
\text{Minimum Level} = \text{Reorder Level} - (\text{Average Consumption} \times \text{Average Lead Time})
\]
For instance, if the reorder level is 600 units, average consumption is 180 units, and average lead time is 2 weeks, then:
\[
\text{Minimum Level} = 600 - (180 \times 2) = 240 \text{ units.}
\]
Therefore, the stock should never go below 240 units.
Danger Level
The danger level represents the point at which inventory has fallen to a dangerously low amount. When stock reaches this level, immediate action is required to replenish materials, often through emergency purchases. The formula is:
\[
\text{Danger Level} = \text{Average Consumption} \times \text{Emergency Lead Time}
\]
For example, if average consumption is 180 units per week and emergency lead time is 1 week, the danger level is \(180 \times 1 = 180\) units. This serves as a warning signal for management to act quickly.
Average Stock Level
The average stock level provides an estimate of the typical inventory held during a given period. It helps assess whether stock is being maintained efficiently. The formula is:
\[
\text{Average Stock Level} = \frac{\text{Minimum Level} + \text{Maximum Level}}{2}
\]
Using the earlier example, where the minimum level is 240 units and the maximum level is 700 units, the average stock level would be:
\[
\text{Average Stock Level} = \frac{240 + 700}{2} = 470 \text{ units.}
\]
This means, on average, the company maintains around 470 units in stock during normal operations.
Reorder Quantity (Economic Order Quantity)
Reorder quantity or Economic Order Quantity (EOQ) is the optimal order size that minimizes the total cost of ordering and holding inventory. It ensures that stock is replenished economically and continuously. The formula is:
\[
\text{EOQ} = \sqrt{\frac{2AB}{CS}}
\]
Where:
A = Annual consumption in units
B = Ordering cost per order
C = Cost per unit
S = Storage or carrying cost percentage
For example, if a company consumes 10,000 units annually, ordering cost is Rs. 200 per order, cost per unit is Rs. 10, and carrying cost is 20% of the cost per unit, then:
\[
\text{EOQ} = \sqrt{\frac{2 \times 10,000 \times 200}{10 \times 0.2}} = \sqrt{2,000,000} = 1,414 \text{ units (approx.)}
\]
This means each order should ideally be for 1,414 units.
Lead Time
Lead time is the time interval between placing an order and receiving the materials. It includes order processing, supplier preparation, and transportation time. Shorter lead times improve flexibility and reduce the risk of stock-outs. For instance, if a supplier takes 10 days to deliver goods after receiving an order, the lead time is 10 days. Companies often keep a safety stock to cover this period.
Safety Stock
Safety stock refers to the additional quantity of inventory kept as a buffer to protect against uncertainties such as sudden demand increases or supplier delays. It ensures that production continues smoothly even under unexpected conditions. For example, if the average demand is 100 units per week, but occasionally spikes to 150 units, maintaining a safety stock of 50 units prevents stock-outs during peak demand periods.
Buffer Stock
Buffer stock is similar to safety stock but is generally maintained for raw materials that have fluctuating supply or prices. It helps protect the company from disruptions caused by strikes, natural calamities, or price volatility. For instance, a textile company might hold extra cotton during harvest season when prices are low to safeguard against future price hikes or shortages.
Stock Turnover Ratio
The stock turnover ratio measures how many times inventory is sold and replaced over a specific period. It indicates inventory efficiency and is calculated using the formula:
\[
\text{Stock Turnover Ratio} = \frac{\text{Cost of Goods Sold}}{\text{Average Inventory}}
\]
For example, if the cost of goods sold during the year is Rs. 500,000 and the average inventory is Rs. 100,000, the stock turnover ratio is \(500,000 / 100,000 = 5\). This means inventory is turned over five times during the year.
Importance of Inventory Levels
Maintaining appropriate inventory levels helps balance production needs with cost efficiency. Too little stock can halt production, while too much stock ties up capital and increases storage costs. Effective inventory control ensures material availability, smooth operations, and minimal waste, directly contributing to higher profitability and better customer satisfaction.
Conclusion
In conclusion, inventory control techniques such as ordering level, maximum level, minimum level, and danger level play a vital role in balancing production flow and cost efficiency. By calculating and maintaining these levels correctly, organizations can avoid production delays, reduce excess inventory costs, and ensure smooth, continuous operations. Practical examples and accurate record-keeping make inventory management both strategic and cost-effective for long-term success.
Introduction
In manufacturing industries, it is essential to determine the cost of production accurately to control expenses and set proper prices. Two commonly used costing methods are process costing and job order costing. Both systems aim to calculate the total production cost, but they differ based on the nature of production, type of output, and cost accumulation process. In Pakistan, different industries use these methods according to their production structure and operational needs.
Meaning of Process Costing
Process costing is a method used where production is continuous, and products pass through several processes or departments before completion. It is applied in industries that produce large quantities of homogeneous or identical units. The cost of each process is collected separately, and then the average cost per unit is determined by dividing the total process cost by the number of units produced. For example, in the textile or cement industry in Pakistan, production occurs in stages such as mixing, molding, finishing, and packaging. Each process incurs material, labor, and overhead costs, which are accumulated and averaged to find the per-unit cost.
Meaning of Job Order Costing
Job order costing is used when production is based on specific customer orders, and each job is distinct from the others. In this system, costs are accumulated separately for each job or work order. This method is suitable for industries where products are customized or produced in small batches. For instance, a furniture manufacturing company in Pakistan such as Interwood or Habitt uses job order costing since each furniture design or order may vary in terms of material, labor, and finishing. Every job is treated as a separate cost unit, and the total job cost is determined by adding all related expenses.
Nature of Production
The most basic difference between the two methods lies in the nature of production. In process costing, production is standardized and carried out in a continuous flow. Each unit produced is identical, making it suitable for mass production industries like paint, sugar, or paper mills in Pakistan. In job order costing, production is customized and based on specific client requirements. Each job may differ in design, material, and process, such as in printing presses or automobile repair workshops.
Cost Accumulation
In process costing, costs are accumulated for each department or process over a certain period. After all costs are gathered, the total is divided by the number of units produced to get an average cost per unit. On the other hand, in job order costing, costs are accumulated by individual job. Each job card or job cost sheet records material used, labor hours spent, and overheads applied specifically to that job. This makes job order costing more detailed and suitable for tracking the profitability of each project.
Cost per Unit Calculation
In process costing, the cost per unit is determined by dividing the total process cost by the number of units produced during the period. For example, if a cement plant in Pakistan produces 10,000 bags of cement at a total cost of Rs. 2,000,000, then the cost per unit is Rs. 200. In job order costing, the total cost of a specific job is divided by the number of units within that job. For example, if a tailoring shop completes a uniform order of 100 pieces at a total cost of Rs. 50,000, the cost per unit will be Rs. 500.
Production Type and Product Uniformity
Process costing is suitable for industries where products are uniform and identical, such as flour mills, chemical plants, and oil refineries. Each unit produced is the same and cannot be distinguished from another. In contrast, job order costing is used when each job is unique, such as in machine manufacturing, shipbuilding, or printing. The output of one job may differ completely from another, and costs must be traced accordingly.
Work-in-Progress Treatment
Under process costing, work-in-progress (WIP) occurs at the end of each process because one department’s output becomes another’s input. The cost of unfinished units is calculated using equivalent units of production. In job order costing, work-in-progress represents jobs that are started but not completed by the end of the accounting period. These incomplete jobs remain in progress until finished and are valued based on the accumulated cost to date.
Transfer of Costs
In process costing, costs are transferred from one process to another as the product moves through different stages of production. For example, in a textile factory, the cost from the spinning department is transferred to the weaving department, and then to finishing. In job order costing, there is no cost transfer between processes because each job is treated independently. Once a job is completed, the total cost is transferred to the finished goods account.
Control of Cost
Job order costing provides better cost control since each job’s cost is recorded and analyzed separately. Management can compare estimated costs with actual costs for each job and identify inefficiencies or wastage. In process costing, control is less detailed because costs are averaged over large production runs, making it difficult to identify the source of inefficiency in specific batches.
Industry Examples in Pakistan
Process costing is commonly used in industries such as Pakistan Steel Mills, Fauji Cement, Lucky Cement, and Ittehad Chemicals where production is continuous and products are homogeneous. On the other hand, job order costing is used by organizations such as Pakistan International Airlines Engineering Department, furniture manufacturers like ChenOne, or printing presses like Packages Limited, where each order is distinct and customer-specific.
Information Provided by Each System
Process costing provides information about the average cost per unit, helping companies in setting prices for mass-produced goods. It assists in controlling production costs and maintaining uniform product quality. Job order costing provides information about the cost and profitability of each job. It helps management in deciding which types of jobs are most profitable and how to improve cost efficiency on future orders.
Accounting Treatment
In process costing, costs are recorded in separate process accounts. The debit side records material, labor, and overhead costs, and the credit side records completed output and closing WIP. In job order costing, costs are recorded in job cost sheets or job cards, where all direct and indirect expenses are tracked against a specific job number. When the job is completed, its total cost is transferred to the finished goods account.
Advantages and Disadvantages
Process costing is simple to operate and cost-effective for mass production, but it provides less detailed cost analysis. Job order costing, on the other hand, gives precise job-wise cost information and helps in customized pricing but involves more administrative effort and record-keeping. Each system’s usefulness depends on the production type and business structure.
Conclusion
In summary, process costing and job order costing differ mainly in their approach to cost accumulation, production type, and product nature. Process costing is best suited for continuous and standardized production, while job order costing fits customized and project-based production. In the industrial sector of Pakistan, both methods are widely used according to business needs. Cement, textile, and chemical industries apply process costing, whereas construction firms, furniture makers, and repair workshops use job order costing. Understanding these distinctions helps organizations maintain accurate cost control, improve decision-making, and enhance overall profitability.

Introduction
Payroll disbursement refers to the process of paying employees for their work, including wages, salaries, and other benefits. Every organization needs an effective and reliable method to distribute payments so that workers are compensated accurately and on time. The method used can depend on the organization’s size, technology, and employee preference. Over the years, several methods of payroll disbursement have evolved—from traditional cash payments to modern electronic systems.
1. Cash Payment Method
This is the oldest and most traditional method of payroll disbursement. Under this system, employees are paid their wages in cash directly by the cashier or paymaster. Each employee receives the amount due after signing the pay sheet or wage register. This method is often used in small businesses or where banking facilities are limited. Although it provides immediate access to money, it also has drawbacks such as the risk of theft, fraud, and the need for strict security during cash handling and distribution.
2. Cheque Payment Method
In this method, employees are paid through individual cheques drawn on the company’s bank account. Each worker receives a cheque for the net amount of wages or salary, which can be deposited or cashed at the bank. The cheque system is safer than cash payments because it avoids large cash handling and provides a written record of payment. However, it can be inconvenient for employees who do not have a bank account, and it may also cause delays in payment clearance.
3. Bank Transfer or Direct Deposit Method
This is one of the most widely used modern methods of payroll disbursement. The employer deposits the salary directly into each employee’s bank account electronically, usually through a payroll system or online banking service. This process is efficient, fast, and secure. Employees receive an electronic statement or salary slip indicating details of gross pay, deductions, and net pay. This method is preferred by most organizations today because it minimizes errors, reduces administrative work, and enhances transparency.
4. Payroll Card Method
In this system, employees who do not have bank accounts are issued payroll cards, which work like debit cards. The employer loads the employee’s wages onto the card each pay period, and the worker can use the card to withdraw cash or make purchases. This method is convenient for employees who cannot open a bank account and for employers who wish to eliminate paper cheques and cash handling. However, it may involve small transaction fees for withdrawals or balance inquiries.
5. Money Order or Postal Payment Method
In some cases, especially in remote or rural areas, wages may be sent through money orders or postal services. The employer sends the payment to the employee’s address using an official postal money order. This method is used less frequently today but can still be useful for temporary or seasonal workers who live far from the workplace and do not have banking access.
6. Mobile Banking and Digital Wallets
With advances in financial technology, many organizations now use mobile banking or digital wallet platforms such as Easypaisa, JazzCash, Paytm, or similar services for salary disbursement. Employees receive their pay directly in their mobile account, from which they can withdraw cash or make payments. This system is especially convenient for workers in areas without formal banking services and for companies with large, distributed workforces.
7. Automated Clearing House (ACH) System
The Automated Clearing House system is an electronic network for processing financial transactions in batches. Employers submit a payroll file to the bank, which processes all employee payments simultaneously. ACH is commonly used in large organizations where thousands of employees are paid on the same date. It is highly efficient, reduces errors, and ensures quick processing, but requires strong coordination between payroll and banking systems.
8. Payment through Payroll Management Software
Many modern businesses integrate payroll disbursement with human resource management systems. Payroll software automatically calculates gross salary, deductions, and net pay, and then disburses funds electronically through the bank. This method improves accuracy, saves time, and generates automated records for accounting and tax purposes. It also allows employees to access their salary slips online through a self-service portal.
9. Hybrid Payment Method
Some companies use a combination of different disbursement methods depending on employee type or location. For example, office staff may receive payments through direct bank deposits, while daily wage workers may be paid in cash. Hybrid systems offer flexibility but require careful recordkeeping to ensure that every employee is paid correctly and on time.
10. Payment through Cooperative Banks or Credit Unions
In some organizations, especially in industrial or cooperative sectors, payroll disbursement is managed through cooperative banks or credit unions. Employees may hold accounts in these institutions, and salaries are credited there. This system encourages saving and provides employees with access to low-interest loans or financial support. It is safe and community-oriented, though less common in highly digitized workplaces.
11. Standing Instructions Method
In this method, the employer authorizes the bank to automatically transfer employees’ salaries to their respective accounts on specific dates. This system ensures timely disbursement without manual intervention. It is particularly useful for regular, fixed-salary employees, and it simplifies payroll processing. However, it requires careful setup and monitoring to ensure the correct amount is transferred each month.
12. Comparison of Traditional and Modern Methods
Traditional payroll disbursement methods such as cash and cheque payments are simple but less secure and more time-consuming. They require manual recordkeeping and carry risks of theft or misplacement. Modern methods like electronic transfers, payroll cards, and digital wallets are faster, safer, and more accurate. They reduce human errors and administrative costs while improving employee satisfaction by ensuring timely payments. The choice of method depends on organizational resources, employee preferences, and local infrastructure.
13. Advantages of Electronic Payroll Disbursement
Electronic payment systems offer several benefits including reduced paperwork, instant payment confirmation, improved data security, and easy integration with accounting systems. They help maintain accurate records for audits and tax compliance. Furthermore, they minimize delays and enhance employee trust, which in turn improves overall productivity and morale.
14. Challenges in Payroll Disbursement
Despite technological advancement, some challenges still exist. These include data entry errors, system failures, and the need for employee training in digital payment methods. In areas with limited internet access or banking infrastructure, cash or cheque payments may still be necessary. Employers must ensure proper reconciliation between payroll records and actual payments to prevent discrepancies and maintain transparency.
15. Conclusion
To sum up, the methods of payroll disbursement have evolved from manual to automated systems over time. The main methods include cash payment, cheque payment, bank transfer, payroll cards, money orders, mobile wallets, and automated clearing systems. Each method has its own advantages and limitations. However, with digital transformation, direct bank transfers and electronic systems have become the preferred choice due to their efficiency, security, and ease of use. A well-managed payroll disbursement system not only ensures employee satisfaction but also contributes to organizational credibility and smooth financial management.

Required: Compute the wages of the above workers under Merrick’s Differential Piece Rate Incentive Plan. ▶
Introduction
The Merrick’s Differential Piece Rate System is a scientific incentive plan designed to encourage higher productivity among workers. It modifies the simple piece rate system by introducing three levels of performance with corresponding wage rates. Under this method, the workers who produce less than the standard output are paid at the basic piece rate, those who achieve between 100% and 120% efficiency receive 110% of the basic piece rate, and those who exceed 120% efficiency receive 120% of the basic piece rate. The aim of this system is to motivate workers to increase output by offering higher rewards for higher efficiency while maintaining fairness for all levels of performance.
Given Information
The Margala Pharmaceutical Company has three workers — A, B, and C. Their details are given as follows:
Basic piece rate = Rs 5 per piece
Standard production = 1,920 units per month
Production of each worker:
Worker A = 2,000 units
Worker B = 1,800 units
Worker C = 2,400 units
Step 1: Formula for Efficiency Calculation
To find the efficiency percentage of each worker, we use the formula:
\[ \text{Efficiency (%)} = \left( \frac{\text{Actual Output}}{\text{Standard Output}} \right) \times 100 \]
Step 2: Calculation of Efficiency
Substituting the values for each worker:
For Worker A:
\[ \text{Efficiency} = \frac{2000}{1920} \times 100 = 104.17\% \]
For Worker B:
\[ \text{Efficiency} = \frac{1800}{1920} \times 100 = 93.75\% \]
For Worker C:
\[ \text{Efficiency} = \frac{2400}{1920} \times 100 = 125\% \]
Step 3: Application of Merrick’s Differential Rates
The Merrick system classifies workers into three efficiency levels as follows:
If efficiency is below 100% → Basic rate (100%)
If efficiency is between 100% and 120% → 110% of basic rate
If efficiency is above 120% → 120% of basic rate
Step 4: Determining Applicable Rates for Each Worker
Worker A’s efficiency = 104.17% → falls between 100% and 120%, so the rate is 110% of basic.
Worker B’s efficiency = 93.75% → below 100%, so the rate is 100% of basic.
Worker C’s efficiency = 125% → above 120%, so the rate is 120% of basic.
Step 5: Calculation of Differential Piece Rates
\[ \text{Adjusted Piece Rate} = \text{Basic Rate} \times \text{Percentage Rate} \]
For Worker A:
\[ \text{Rate} = 5 \times 1.10 = 5.50 \]
For Worker B:
\[ \text{Rate} = 5 \times 1.00 = 5.00 \]
For Worker C:
\[ \text{Rate} = 5 \times 1.20 = 6.00 \]
Step 6: Calculation of Total Wages
\[ \text{Total Wages} = \text{Units Produced} \times \text{Adjusted Piece Rate} \]
For Worker A:
\[ \text{Wages} = 2000 \times 5.50 = Rs\,11,000 \]
For Worker B:
\[ \text{Wages} = 1800 \times 5.00 = Rs\,9,000 \]
For Worker C:
\[ \text{Wages} = 2400 \times 6.00 = Rs\,14,400 \]
Step 7: Summary of Calculations
Below is a clear summary table of all workers’ performances and earnings.
| Worker | Units Produced | Efficiency (%) | Applicable Rate | Adjusted Piece Rate (Rs.) | Total Wages (Rs.) |
|---|---|---|---|---|---|
| A | 2000 | 104.17% | 110% of basic rate | 5.50 | 11,000 |
| B | 1800 | 93.75% | 100% of basic rate | 5.00 | 9,000 |
| C | 2400 | 125% | 120% of basic rate | 6.00 | 14,400 |
Step 8: Interpretation of Results
The results show that Worker B, whose efficiency was below standard, received only the basic rate, while Worker A earned slightly more for performing above the standard. Worker C achieved the highest efficiency and thus received a significant increase in earnings under the Merrick’s Differential Piece Rate System. This demonstrates the motivational power of the system, as higher output directly leads to proportionally higher pay.
Step 9: Advantages of Merrick’s Plan
This system effectively rewards high-performing workers while maintaining fairness for others. It encourages employees to improve their efficiency and productivity. Since the increase in rate is gradual (from 100% to 110% to 120%), it provides a balanced approach that avoids extreme competition or fatigue among workers. It also benefits employers by increasing output and reducing labor cost per unit.
Step 10: Conclusion
In conclusion, under Merrick’s Differential Piece Rate System, wages vary according to the efficiency of the worker. Based on the calculations, the total wages are Rs 11,000 for Worker A, Rs 9,000 for Worker B, and Rs 14,400 for Worker C. The system motivates workers to perform better and rewards efficiency, creating a fair and productive working environment.
Material Costs Rs. 176,000
Conversion Costs Rs. 246,000
During the month, 45,000 units with a total cost of Rs. 1,350,000 had been transferred into the department from department. Of these, 40,000 units were completed & transferred to department III, and 5,000 units were in process, on 31st March, 80% completed as to Material, 20% complete as Conversion Cost. ▶
1. Statement of Units
During March 2023 Department II received 45,000 units (transferred in) from Department I. Of these, 40,000 units were completed and transferred to Department III during the month. The closing work in process consisted of 5,000 units which were 80% complete as to materials and 20% complete as to conversion costs. The units reconciliation is:
| Particulars | Units |
|---|---|
| Units transferred in from Dept I | 45,000 |
| Less: Units transferred out to Dept III (Completed) | 40,000 |
| Units in closing WIP (31 March 2023) | 5,000 |
| Total units to account for | 45,000 |
2. Equivalent Units (Weighted Average)
Under the weighted average method the equivalent units are computed by treating transferred-in as 100% complete on receipt and by taking the given completion percentages for materials and conversion for closing WIP. The equivalent units are:
| Cost Element | Units Completed | Equivalent Units in Closing WIP | Total Equivalent Units |
|---|---|---|---|
| Transferred-in (from Dept I) — treated 100% complete on receipt | 40,000 | 5,000 | 45,000 |
| Materials added in Dept II | 40,000 | 5,000 × 80% = 4,000 | 44,000 |
| Conversion costs (labour & overhead) | 40,000 | 5,000 × 20% = 1,000 | 41,000 |
3. Costs to Account For
The costs charged to Department II during the period are given as follows. Transferred-in cost from Department I for the 45,000 units equals Rs. 1,350,000. Costs added in Department II during March 2023 are Material Costs Rs. 176,000 and Conversion Costs Rs. 246,000. The total cost to account for is:
\[ \text{Total Cost} = \text{Transferred-in } 1,350,000 + \text{Materials } 176,000 + \text{Conversion } 246,000 = 1,772,000 \]
| Cost Component | Amount (Rs.) |
|---|---|
| Transferred-in cost (Dept I) | 1,350,000 |
| Materials added in Dept II | 176,000 |
| Conversion costs (labour & overhead) | 246,000 |
| Total cost to account for | 1,772,000 |
4. Cost per Equivalent Unit (Weighted Average)
Now compute cost per equivalent unit for each cost category. Using the equivalent units computed above:
Transferred-in cost per equivalent unit:
\[ \text{Cost per EU (Transferred-in)} = \frac{1,350,000}{45,000} = 30.00 \text{ Rs. per EU} \]
Materials cost per equivalent unit:
\[ \text{Cost per EU (Materials)} = \frac{176,000}{44,000} = 4.00 \text{ Rs. per EU} \]
Conversion cost per equivalent unit:
\[ \text{Cost per EU (Conversion)} = \frac{246,000}{41,000} = 6.00 \text{ Rs. per EU} \]
| Cost Element | Total Cost (Rs.) | Equivalent Units | Cost per EU (Rs.) |
|---|---|---|---|
| Transferred-in | 1,350,000 | 45,000 | 30.00 |
| Materials (Dept II) | 176,000 | 44,000 | 4.00 |
| Conversion (Dept II) | 246,000 | 41,000 | 6.00 |
5. Cost Allocation: Costs Assigned to Units Completed and Ending WIP
Using the cost per equivalent unit, assign costs to the 40,000 completed units and to the 5,000 units in closing WIP.
Cost of units transferred out (40,000 units). For each completed unit the total unit cost is the sum of the three cost elements per unit:
\[ \text{Cost per completed unit} = 30.00 \;(\text{transferred-in}) + 4.00 \;(\text{materials}) + 6.00 \;(\text{conversion}) = 40.00 \]
Therefore cost of units transferred out = \(40,000 \times 40.00 = 1,600,000\) Rs.
Cost of ending WIP (5,000 units). Compute component-wise using equivalent units for closing WIP:
| Cost Element | EU in Closing WIP | Cost per EU (Rs.) | Amount (Rs.) |
|---|---|---|---|
| Transferred-in | 5,000 | 30.00 | 150,000 |
| Materials (80% of 5,000 = 4,000 EU) | 4,000 | 4.00 | 16,000 |
| Conversion (20% of 5,000 = 1,000 EU) | 1,000 | 6.00 | 6,000 |
| Total Ending WIP Cost | 172,000 | ||
6. Cost Reconciliation (Check)
Now reconcile total costs to ensure costs assigned equal costs to account for.
| Particulars | Amount (Rs.) |
|---|---|
| Cost of units transferred out (40,000 × 40.00) | 1,600,000 |
| Cost of closing WIP | 172,000 |
| Total costs assigned | 1,772,000 |
| Total costs to account for | 1,772,000 |
7. Summary and Key Results
Using the weighted average method for Department II for the period ended March 2023, the key outcomes are shown below. The cost per equivalent unit for transferred-in is Rs. 30.00, for materials added in Dept II is Rs. 4.00, and for conversion costs is Rs. 6.00. The cost assigned to the 40,000 completed units transferred to Department III is Rs. 1,600,000. The cost of the 5,000 units in closing work-in-process (80% materials, 20% conversion) is Rs. 172,000. The totals reconcile to the total cost to account for Rs. 1,772,000.
8. Notes and Assumptions
The report uses the weighted average (average cost) method. Equivalent units for transferred-in were treated as 100% complete on receipt. Materials and conversion percentages for closing WIP are as given. All calculations rounded to two decimals where appropriate, but final figures are expressed in whole rupees for clarity. If you want the same report prepared under FIFO or with an alternative presentation (for example a single detailed cost of production statement layout), I will prepare that immediately.
Introduction
In every manufacturing or service organization, overhead costs are incurred not only in the producing departments but also in servicing departments such as maintenance, power, stores, and personnel. While producing departments are directly involved in creating the final product, service departments provide essential support that helps production run smoothly. Since service departments do not produce goods directly, their overhead costs need to be distributed or allocated to the producing departments to determine the true cost of production. This process is known as the allocation and proration of service department overheads.
1. Meaning of Allocation and Proration
Allocation means assigning the entire overhead cost of a service department to a specific producing department when that cost is directly related to that department. Proration, on the other hand, refers to the process of distributing shared overhead costs among several departments based on a fair and logical basis such as labor hours, machine hours, or floor area. The goal of both processes is to ensure that every department bears a fair share of total overhead costs, leading to accurate product costing.
2. Need for Allocation of Service Department Costs
The allocation of service department costs is important for several reasons. It helps in finding the total cost of production more accurately and ensures fair distribution of indirect expenses. It also assists management in identifying the efficiency of various departments, supports decision-making related to pricing and budgeting, and helps in evaluating departmental performance. Without proper allocation, the cost of goods may be understated or overstated, which can mislead management decisions.
3. Methods of Allocating Service Department Costs
There are several recognized methods for allocating and prorating the overhead costs of service departments to producing departments. The most commonly used ones are the direct method, step ladder (or sequential) method, and reciprocal (or algebraic) method. The choice of method depends on the size of the organization, the nature of services provided, and the degree of interdependence between departments.
4. The Direct Method
Under the direct method, service department costs are allocated only to producing departments, ignoring any services provided by one service department to another. The assumption here is that service departments work independently and serve only production departments. For example, if the maintenance department serves both production and personnel departments, only the share of production departments will be considered. Although this method is simple and easy to apply, it does not reflect the true cost relationships where service departments support each other.
5. The Step Ladder Method (or Sequential Method)
The step ladder method recognizes that service departments may provide services to each other but in a limited sequence. In this method, service departments are ranked in the order of the amount of service rendered to other departments. The department providing the greatest amount of service to others is distributed first. After allocating its cost to all departments (both service and producing), that department is closed, and the process continues with the next service department. This method is more accurate than the direct method because it partially accounts for interdepartmental services.
6. The Reciprocal (or Algebraic) Method
The reciprocal method is the most accurate and comprehensive method for allocating service department costs. It recognizes the mutual services exchanged among service departments. For instance, the maintenance department may provide services to the power department, and the power department may, in turn, provide electricity to the maintenance department. Using simultaneous equations, the reciprocal method determines the total cost of each service department, including the share of services received from other service departments, before allocating those costs to production departments. Though it involves complex calculations, it provides the most realistic and precise results.
7. The Repeated Distribution Method
This method is a simplified alternative to the reciprocal method. Here, service department costs are repeatedly apportioned to other departments, including other service departments, in proportion to the services rendered until the remaining balance becomes negligible. The process continues until all service department costs are fully transferred to producing departments. It provides results similar to the reciprocal method but is easier to apply when the number of departments is small.
8. Simultaneous Equation Method
This is a mathematical version of the reciprocal method. In this approach, simultaneous equations are formulated to represent the interrelationship of service departments. Each equation represents the total cost of a service department as its own overhead cost plus the share of costs received from other service departments. Solving these equations gives the total cost of each service department, which is then distributed to producing departments. It is accurate but requires careful computation and is more suitable when data are processed through computer-based systems.
9. Example Illustration
Suppose there are two service departments, Maintenance and Power, and two production departments, A and B. The total overhead costs before allocation are Rs. 40,000 for Maintenance and Rs. 60,000 for Power. If Maintenance provides 20% of its service to Power and Power provides 10% of its service to Maintenance, the reciprocal method will use simultaneous equations as follows: \[ M = 40,000 + 0.10P \] \[ P = 60,000 + 0.20M \] Solving these, we get \[ M = 40,000 + 0.10(60,000 + 0.20M) \] \[ M = 40,000 + 6,000 + 0.02M \] \[ 0.98M = 46,000 \] \[ M = 46,938.78 \] Substitute \( M \) into the equation for \( P \): \[ P = 60,000 + 0.20(46,938.78) = 69,387.76 \] Now, the total costs of Maintenance and Power are Rs. 46,938.78 and Rs. 69,387.76 respectively, which can then be allocated to producing departments A and B based on their usage ratios. This demonstrates how the reciprocal method gives a more accurate allocation.
10. Basis of Apportionment
While allocating service department costs, an appropriate basis must be chosen to reflect the usage of services fairly. For instance, power cost may be apportioned based on machine hours, maintenance cost based on the number of repairs, personnel cost on the number of employees, and canteen cost on the number of meals served. Choosing the right basis ensures that each department is charged proportionally to the benefits it receives from the service department.
11. Factors Affecting the Choice of Method
The choice of allocation method depends on factors such as the size of the organization, the number of service departments, the complexity of interdepartmental relationships, and the accuracy required in cost data. Small firms with simple operations may prefer the direct or step ladder method, while larger firms with multiple interdependent departments often choose the reciprocal or simultaneous equation method for higher accuracy.
12. Importance of Proper Allocation
Accurate allocation of service department overheads ensures that the cost of production reflects the true use of resources. It also helps management in cost control and performance evaluation. When each department is charged fairly, management can identify inefficiencies, make informed pricing decisions, and improve budgeting and planning processes.
13. Limitations of Allocation Methods
Each method has its limitations. The direct method oversimplifies cost relationships by ignoring interdepartmental services. The step ladder method improves accuracy but only partially considers mutual services. The reciprocal and equation methods are accurate but computationally complex and time-consuming. Therefore, organizations often balance accuracy and simplicity based on their operational needs and data handling capabilities.
14. Most Accurate and Realistic Method
Among all methods, the reciprocal or simultaneous equation method provides the most accurate and realistic results. This is because it fully recognizes the mutual services exchanged among service departments and determines the total cost of each department before allocation. Although it is more complex to apply, especially manually, modern computerized accounting systems can handle such calculations easily, making this method practical for large organizations.
15. Conclusion
To conclude, the allocation and proration of service department costs are vital for determining the true cost of production. The methods commonly used include the direct method, step ladder method, repeated distribution method, and reciprocal (or algebraic) method. While simpler methods are useful for small organizations, the reciprocal method offers a more comprehensive and precise approach. By recognizing interdepartmental services, it gives management a realistic picture of overhead distribution and supports more accurate cost analysis, budgeting, and pricing decisions.
