Process costing is a method wherein the products go through two or more processes. The costs are assigned/charged to individual processes or operations, averaged over the number of units produced during the said period. It is used commonly in manufacturing units like paper, steel, soaps, medicines, vegetable oils, paints, rubber, chemical, etc. use this method widely.

A product may be manufactured through one process or more than one process. If two or more processes are involved in manufacturing one finished product, the question arises, “which process has consumed the expense?” The answer lies within process costing. It helps identify the specific cost assigned to each process. It enables the management to further decision making.

#1 – Weighted Average Method of Process Costing

Here the actual cost is divided by the weighted averageThe weighted average formula is simply summing up the products of each value with its respective weightage. Here, more significance is given to the weightage of the values rather than the variables themselves.read more of products produced. This calculation is simple as compared to any other method. A weighted average of units means the summation of the product of the rate and quantity of each item.

#2 – Standard Cost

Here the actual cost of units is not considered; instead, it follows a standard costing methodStandard cost is an estimated cost determined by the company for the production of the goods and services or for performing an operation under normal circumstances and are derived by the company from the historical analysis of the data or from the time and the motion studies.read more. Standard cost assumes the cost of certain materials as per management estimate. Any difference in standard & actual costs is recorded separately under the variance account

#3 – First-In-First-Out

This method assigns the expense of first inputs to the processes in the order of production. However, it does not precisely identify which a lot of raw material is taken for production and its procurement rate.

Step#1 – Record of Inventory

This step involves the identification of inventory at the end of each process. The organization can identify such inventory by physically counting the units or through software inbuilt into the manufacturing process. In addition, the costs of inventory under each process are also identified at this change.

Step #2 – Conversion of Work in Process Inventory

Apply the percentage of completionThe percentage of completion method is an accounting method for recognizing revenue and expenses for long-term projects that span over more than one accounting year. The revenue is recognized yearly as a percentage of work completed during that year. Revenue to be recognized = (Percentage of Work Completed in the given period) * (Total Contract Value) read more to the units which are under any process & not yet completed the production. Say 80,000 units of soaps are under process & these are 60% completed. Then the equivalent completed units are 80,000*60% i.e. 48,000 units.

Step #3 – Calculation of Inventory Costs

Here, the organisation calculates the direct costDirect cost refers to the cost of operating core business activity—production costs, raw material cost, and wages paid to factory staff. Such costs can be determined by identifying the expenditure on cost objects.read more and indirect costsIndirect cost is the cost that cannot be directly attributed to the production. These are the necessary expenditures and can be fixed or variable in nature like the office expenses, administration, sales promotion expense, etc.read more in the production phase. These costs are accumulated from the first process to the last process. The said is then bifurcated into an inventory of complete products & inventory of products that are under process.

Step #4 – Calculation of Per-Unit Cost of Inventory

We calculate this by dividing the total cost by equivalent completed units in the production phase. The cost per unit calculated here reflects the cost of only completed units. The basis of equivalent units can be the weighted average, standard cost, or first-in-first-out inventory methodUnder the FIFO method of accounting inventory valuation, the goods that are purchased first are the first to be removed from the inventory account. As a result, leftover inventory at books is valued at the most recent price paid for the most recent stock of inventory. As a result, the inventory asset on the balance sheet is recorded at the most recent cost.read more.

Step #5 – Allocation of Costs

The per-unit costs are then split according to the number of units completed & units that are under process.

When Is Process Costing System Suitable?

Process costing is suitable for industries where the product is continuous and the end products are identical. Also, the entire process of production is standardized. In such industries, the production cycle is standardized & even the quantum of the normal loss of inputs & outputs is quantified earlier. In case of abnormal expense, it is a charge to the profit & loss account directly and not to any individual process.

Industries such as cement, soaps, steel, paper, chemicals, medicines, vegetable oils, rubber, etc., use this method to assign the costs.

Features

Each plant is divided into several processes/centers. Each such division is a stage of production or process. Thus, we first clearly identify the cost centers.
Direct & indirect costs are assigned and accumulated to each process in the factory.
The output of one process may become input for another process.
The finished products are identical & cannot be easily distinguished unless batch coding is done.
The production process is continuous for all days in the year except for regular breakdown hours required to maintain the machinery.
The total cost of production is divided among each process on a suitable basis.
The company is required to keep records for each production process, such as units or costs introduced in each process and passed on to the next stage of production.
The production may result in joint products or by-products.

Conclusion

Process cost allows an organisation to assigns the cost to different steps in the production phase. It helps management in decision making. The organisation can use this method to identify the relevant costsRelevant cost is a management accounting term that describes avoidable costs incurred when making specific business decisions. This concept is useful in eliminating unnecessary information that might complicate the management's decision-making process. For example, businesses use relevant costs in management accounting to conclude whether a new decision is economical.read more (i.e., direct and indirect costs) for each process, and no abnormal expenses are charged to any process.
