Accurate cost allocation and determination of the cost per unit are crucial in industries where continuous processes occur. Costing techniques enable companies to accumulate and allocate costs, determine the cost per unit, and report cost information for each production process. Companies in these industries can use process costing to achieve that.
What is Process Costing?
Process costing is a managerial accounting method of calculating the cost of producing large quantities of identical or similar products or services. It is prevalent in industries where production occurs through continuous or repetitive processes. Usually, it involves accumulating and allocating costs to determine the cost per unit used for valuation and accounting purposes.
In process costing, the costs incurred during each production process get accumulated and allocated to the units produced. The total costs incurred in each step are then get divided by the total units produced to determine the cost per unit. Consequently, this cost per unit helps in valuation and accounting purposes, such as determining the cost of goods sold and valuing inventory.
How does Process Costing work?
There are several steps involved in process costing, as listed below.
- Collecting costs: All costs incurred during each production process get accumulated and recorded in appropriate cost accounts.
- Assigning costs: The accumulated costs in each production process get allotted to the units produced during that process. It occurs by using a predetermined allocation method, such as using the average cost per unit or allocating costs based on the physical units produced.
- Determining cost per unit: The total costs incurred in each production process get divided by the total units produced during that process to determine the cost per unit.
- Reporting: The cost per unit determined in each process gets used for valuation and reporting purposes, such as determining the cost of goods sold and valuing inventory.
Some companies may have more than one production process. Therefore, they must repeat these steps individually.
What is the importance of Process Costing?
Process costing is essential for businesses with continuous or repetitive production processes. It enables accurate cost determination, as costs get tracked and allocated to each production process. Consequently, it helps determine the cost per unit and valuing inventory and cost of goods sold. This information is crucial for financial reporting and decision-making.
Process costing also allows for effective cost monitoring, as costs get systematically tracked at each stage of the production process. Therefore, it helps companies identify cost variances, analyze cost trends, and take corrective actions to manage costs efficiently. Process costing also helps in production planning by providing cost information that allows businesses to optimize production levels, adjust production schedules, and ensure efficient resource utilization.
What are the limitations of Process Costing?
Process costing, like any costing method, has its limitations. One limitation is the lack of accuracy in cost allocation, as costs get estimated, assumed, or averaged across production processes, which may not reflect the actual resource utilization. Consequently, it can result in distorted cost information, affecting decision-making and financial reporting.
Process costing may also face challenges in tracking individual product costs, as costs get allocated to production processes rather than single products. It can make it difficult to determine the cost of each product. Similarly, process costing may not accurately capture unique costs, such as specific labour or overhead costs, which can result in incomplete cost information.
Conclusion
Process costing is a prevalent method applying industries involving continuous or repetitive production processes. It offers benefits, for example, simplicity, ease of use, and the ability to provide cost information for mass-produced or similar products. However, it may also have some limitations, as listed above.
