Key differences between Job Costing, Batch Costing, Process Costing
| Basis of Comparison | Job Costing | Batch Costing | Process Costing |
|---|---|---|---|
| Production Type | Customized | Identical lots | Continuous flow |
| Cost Object | Job/Order | Batch/lot | Process/phase |
| Cost Calculation | Per job | Per batch | Per process period |
| Output Nature | Discrete units | Grouped units | Homogeneous mass |
| Work-in-Progress (WIP) | Minimal | Moderate | High/continuous |
| Cost Transfer | Not applicable | Batch to batch | Process to process |
| Identity Maintenance | Per job | Per batch | Lost automatically |
| Product Standardization | No | Partial | Complete |
| Industry Example | Printing, repair | Pharmaceuticals, biscuits | Cement, oil |
| Cost Control | Individual job | Batch level | Process level |
| Idle Time | Significant | Moderate | Negligible |
| Production Continuity | Intermittent | Semi-continuous | Continuous |
| Job/Batch/Process Cost Sheet | Separate per job | Separate per batch | Per process account |
| Suitability | Small scale | Medium scale | Large scale |
| Recording Complexity | High | Medium | Low |
Job Costing
Job costing is a method of costing used to determine the cost of a specific job, project, or order separately. Under this method, costs of materials, labour, and overheads are collected and assigned to each individual job. It is mainly used where production is customized according to customer requirements. Every job is treated as a separate unit and cost is calculated individually. Job costing helps businesses measure profitability, control costs, and fix suitable selling prices. This method is commonly used in construction, printing, furniture making, repair works, and specialized manufacturing industries where products or services differ from one another.
Batch Costing
Batch costing is a method of costing in which the cost of a group or batch of identical products is calculated together. Instead of finding the cost of each unit separately, total production cost is divided by the number of units in the batch to determine cost per unit. This method is suitable for industries producing goods in batches according to demand or production schedules. Batch costing helps in cost control, pricing decisions, and efficient production planning. It is commonly used in industries such as pharmaceuticals, garments, toys, bakery products, and electronic components where similar products are manufactured in large quantities together.
Process Costing
Process costing is a method of costing used in industries where production is continuous and products are identical or homogeneous. Under this method, costs are collected for each process or department separately for a specific period. The total process cost is divided by the number of units produced to determine the cost per unit. It is suitable for mass production industries where goods pass through different stages of production. Process costing helps in cost control, performance evaluation, and pricing decisions. This method is commonly used in industries such as oil refining, chemicals, paper, cement, textiles, food processing, and paint manufacturing.
