Under process costing generally all the material required for production is purchased and issued to the first process. The output in whatever form of the first process becomes the raw material for the next process and so on. In different processes additional material may be added as per the nature and the requirement of the product. The whole of material issued or used for the process is shown in the debit side of the process account. Process Costing refers to a method of accumulating cost of production by process.
Understanding Process Costing: How It Works and Why It Matters

In certain industries, there arise by-products or joint-products, which require further processing. The factory is divided into a number of process cost centers or departments and in each cost center an account is maintained—setting up progress cost centers. If the product is processed in more than one process costing process, the output of the first process is transferred to the second process.

Standard Cost Method
- (1) The production of goods is continuous, except where the plant is shut-down for repairs, until the final product.
- The total number of units produced during a given period is calculated and by dividing the total cost of a process by the total number of units produced, the cost per unit shall be obtained.
- Unlike tracking costs for custom products, this methodology averages expenses across homogeneous output, making it ideal for mass production environments.
- Process costing in cost accounting is a methodology used to allocate production costs across multiple stages or processes involved in manufacturing a product or offering a service.
- This lets management monitor unit cost, control margins and react quickly if material, energy or labor costs start to rise.
- Each template below can be customized to fit the unique needs of your production line.
- A separate account is opened for each process to which all costs incurred thereon are charged.
Units receive standard cost assignments based on equivalent unit calculations, while variance accounts capture cost differences for management analysis. Implementing effective process costing requires a systematic approach that ensures accurate cost allocation and meaningful management https://scrubguru.pk/adjusting-journal-entries-what-are-they-what-are/ information. The five-step methodology provides a structured framework for calculating unit costs and valuing inventory. However, many manufacturing operations combine elements of both mass production and customization. A furniture manufacturer might use process costing for standard chair production while employing job costing for custom executive desks. This hybrid approach allows optimal cost tracking for different product lines within the same facility.
The 5 Essential Steps in Process Costing
Process costing refers to a method of accumulating cost of production by process. It is used in mass production industries producing standard products like steel, sugar, chemicals, oil, etc. In all such industries, goods produced are identical and all factory processes are standardised.
It is concerned with the determination of the cost of each operation rather than the process. Cash Flow Statement In those industries where a process consists of distinct operations, the method of costing may be called operation costing, though it is still process costing in approach and application. Process costing relies on average costs, which can mask variations in efficiency or quality. If one batch of products requires more resources due to quality issues, the averaging effect spreads these costs across all units, potentially hiding the true cost of the problematic batch. Food processing operations, for example, begin with the direct material, such as a potato, and gradually transform the direct material into finished products (such as wafers) by various rendering operations. The use of process costing can help companies provide products at competitive prices.
- The value of opening WIP is added to the costs incurred during the current accounting period, and the total cost is divided by the total equivalent units to get the average cost of equivalent units.
- The fundamental principle behind process costing lies in its assumption that all units produced during a given period incur essentially the same production costs.
- Motor spirit, kerosene oil, fuel oil, lubricating oil, wax, tar and asphalt are the examples of joint products produced from crude petroleum.
- Whether they’re operating machines or assembling products by hand, the direct labor costs incurred are spread evenly across all units.
(c) Determine the cost per unit of normal production by dividing the result of step No. 2 by result of step No. 1. By past experience and data available relating to industry, a rate of normal loss is always mentioned with specification of production techniques. If the loss is within the specified limit, it is referred to as normal loss.

Process Costing is Applicable in Industries:

Instead of tracking costs per unit, as in job costing, process costing averages the costs up and down the manufacturing process. The costs can be allocated to both the finished product and WIP (work in process) inventory. Partially completed product is treated in the same manner as completed product by handling them all as equivalent units and then determining the average cost per each. Process costing systems maintain one work-in-process account per department or production stage, accumulating costs as products flow through the manufacturing process. Job costing, conversely, creates separate accounts for each individual job or project, tracking materials, labor, and overhead specific to that particular order. As a process costing example, ABC International produces purple widgets, which require processing through multiple production departments.
