Methods of Costing
1. Job Costing
Job costing is a method used where production is carried out according to specific customer orders. Each job is treated as a separate cost unit, and costs are accumulated individually for every job. Materials, labour, and overheads are recorded separately for each assignment. This method is commonly used in construction companies, printing presses, repair workshops, and interior design firms. Job costing helps determine the exact cost and profitability of each job. It provides detailed cost information and supports effective cost control. Therefore, it is suitable for customized and non-repetitive production activities.
2. Batch Costing
Batch costing is an extension of job costing where a group of identical products is treated as a single cost unit. Costs are accumulated for the entire batch and then divided by the number of units produced to determine the cost per unit. This method is suitable for industries producing goods in batches, such as pharmaceutical companies, bakeries, garment manufacturing, and electronic component production. Batch costing helps simplify cost calculations and improve production efficiency. It is particularly useful when products are manufactured in lots rather than individually.
3. Contract Costing
Contract costing is used for large-scale projects that extend over a long period and are usually carried out at specific sites. Each contract is treated as a separate cost unit, and costs are recorded individually for each contract. This method is commonly used in construction, shipbuilding, road development, and engineering projects. Contract costing helps monitor project expenses and determine contract profitability. It also assists management in controlling costs and evaluating project performance. Due to the size and duration of contracts, detailed records are maintained throughout the project period.
4. Process Costing
Process costing is used in industries where production is continuous and products pass through various stages or processes. Costs are accumulated for each process or department and then allocated to units produced. This method is suitable for industries such as oil refining, chemical manufacturing, cement production, paper mills, and food processing. Since products are identical and produced continuously, individual cost identification is not possible. Process costing helps determine the average cost per unit and supports efficient cost management. It is one of the most widely used costing methods in manufacturing industries.
5. Unit or Single Costing
Unit costing, also known as single costing, is used where only one type of product is manufactured. The cost per unit is determined by dividing total production cost by the number of units produced. This method is suitable for industries producing homogeneous products such as bricks, cement, sugar, coal, and steel. Unit costing provides simple and accurate cost information for cost control and pricing decisions. It is easy to apply because the products are identical in nature. Therefore, it is commonly used in industries with standardized production.
6. Operating Costing
Operating costing, also called service costing, is used in service organizations rather than manufacturing concerns. It determines the cost of providing services to customers. This method is commonly applied in transport companies, hospitals, hotels, educational institutions, and power supply organizations. Costs are collected and analyzed according to the nature of services rendered. Operating costing helps management fix service charges, control operating expenses, and evaluate efficiency. Since services cannot be stored like products, cost determination focuses on the cost of service units such as passenger-kilometers or room occupancy.
7. Multiple Costing
Multiple costing is used when a product consists of several components manufactured through different processes and costing methods. It combines two or more costing methods to determine the total cost of a product. This method is commonly used in industries such as automobile manufacturing, aircraft production, and machinery manufacturing. For example, process costing may be used for certain parts while job costing may be used for assembly operations. Multiple costing provides comprehensive cost information and ensures accurate cost determination for complex products.
8. Operation Costing
Operation costing is a combination of job costing and process costing. It is used when products pass through a series of operations and some degree of customization is involved. Costs are accumulated for each operation and assigned to products accordingly. This method is suitable for industries such as footwear manufacturing, textile production, and engineering industries. Operation costing helps determine costs accurately where production involves repetitive operations but products differ in specifications. It provides a balance between process costing and job costing, making it useful for semi-standardized production systems.
9. Departmental Costing
Departmental costing is a method where costs are collected and analyzed separately for each department within an organization. Each department is treated as a cost center, and the cost of operations performed by that department is determined individually. This method helps management evaluate departmental efficiency and control costs effectively. It is commonly used in large manufacturing organizations where production activities are divided among various departments. Departmental costing provides detailed information for performance evaluation and resource allocation. Therefore, it supports better managerial control and decision-making.
10. Composite Costing
Composite costing is used when a business produces a combination of products that are closely related or jointly manufactured. Costs are accumulated collectively and then allocated among the different products using suitable methods. Industries such as petroleum refining, dairy processing, and chemical manufacturing commonly use composite costing. This method helps determine the cost of multiple products produced simultaneously from the same raw materials. It ensures fair cost allocation and supports profitability analysis. Composite costing is especially useful where joint products and by-products are generated during production.
