3 3: Process Costing Calculations for a Department in a Manufacturing Company Business LibreTexts

The process costing system is an organized method to calculate the average cost per unit by considering the total costs spread across all the units produced. In this way, the costs accrued in each department or process are allocated to each product accurately, within a specific manufacturing sector. Calculating the applicable costs is the next step in the process costing system.

• (1) The production of goods is continuous, except where the plant is shut-down for repairs, until the final product.
• The most important factors of process costing include the type of industry where the business is operating, and the type of product being manufactured.
• Harold Averkamp (CPA, MBA) has worked as a university accounting instructor, accountant, and consultant for more than 25 years.

Process costing is an accounting methodology that traces and accumulates direct costs, and allocates indirect costs of a manufacturing process. Costs are assigned to products, usually in a large batch, which might include an entire month's production. It assigns average costs to each unit, and is the opposite extreme of Job costing which attempts to measure individual costs of production of each unit.

Determine the per-unit cost

Companies needing to refine their process can simply add or remove a process as necessary. The three components of process cost are direct materials, direct labor, and manufacturing overhead. Accurately assessing these components helps to track and allocate production costs across different stages or processes. In a process cost system, costs are maintained by each department, and the method for determining the cost per individual unit is different than in a job order costing system.

• These are the cooking process, forming process, cooling process, and wrapping process.
• When we assign a cost to a product, we can use job costing if it is a unique product or a service and we can assign the costs directly.
• Tesla Corporation, which adds materials at the beginning of production, uses a weighted-average process-costing system.
• In this example, two groups—administrative and manufacturing—report directly to the chief financial officer .

If any deviation between the actuals and the budget and the standards is identified, corrective measures are taken. Budgets are prepared, standards are established, actuals are ascertained, and then a comparison is made. To fulfill the underlying idea behind this norm, it is important to control the cost so as to reduce the cost of a tax deductions for your photography product or service. As such, the norm that everyone attempts to follow is "the lower the cost, the greater to profit." A bookkeeping expert will contact you during business hours to discuss your needs.

After a production run has been completed, the estimated totals are compared to the actual totals, and the difference is added to a variance account, which is a record of the variances. Your inventory may need to be reported to the tax authorities, depending on your business type. It can be challenging for large companies to track thousands or even millions of products. The value of each item produced is recorded, and each department keeps track of different aspects of the business.

Overhead Costs

The main objective is to allocate total manufacturing costs to the various products according to the proportion of resources consumed by each product. A process costing system accumulates the costs of a production process and assigns them to the products that the business outputs. (6) In case there is loss or wastage of units in any process, the loss has to be borne by the good units produced in that process, and as a result, the average cost per unit increases to that extent. When the candy is going through these stages, it is really work in process (WIP). Ultimately it will go to finished goods and then the cost of goods sold in our accounting records. With process costing, we will have a WIP account for each process (department) where we will record all the costs that go into making the candy during that process.

What Is Process Costing and Why It's Important?

This matching process helps to determine and improve the profitability of the product. Assembly lines can be combined or separated based on actual production and resource management. It is much easy for management to spot the weakness of each process by comparing their cost and output. Company ABC is manufacturing which specializes in shoe production, they mainly focus on the local market. The production needs to go through multiple processes which they called the departments. As we move from process to process, we will decrease the WIP account of the cooking process and increase the WIP account for the forming process, and so on.

(2) Each Process Account is debited with material cost, labour cost, direct expenses and overheads allocated or apportioned to the process. Overheads incurred on two or more processes are apportioned on the basis of direct wages or on any other suitable basis. Sometimes overheads are recorded at pre-determined rate based on direct wages, prime cost, etc. The output or the part of output at the stage of every process can be sold out either at profit or loss. Thus the management can know about the profit or loss at every process by preparing Processes Account. Process costing is easier for the owner, because the business only has to track costs for a particular batch of combs.

It reveals the inefficiencies at various levels, and it also helps to identify the exact cause of a decrease or increase in the profit or loss of a business (as a whole or unit-wise, as required). To ascertain the cost of management, with the help of the costing department, it is worthwhile to make preliminary investigations and introduce a system for recording costs. The question of what technique and process to use depends on the nature of the industry, the type of product, and the method of production.

Monitor profit margins

Let's consider industries where the output units are uniform and individually not worth a lot. For example, reams of paper or bottles of soda, where the production costs for each unit are impossible or difficult to trace. Let's dive in to understand what is process costing, the types of process costing, and how it is calculated along with process costing system examples. Process costing is employed by the industries whose production process is continuous and repetitive, as well as the output of one process is the input of another process. So, chemical industry, oil refineries, cement industries, textile industries, soap manufacturing industries, paper manufacturing industries use this method.

When using this method, the total number of units completed and transferred out is added to the equivalent units of work-in-progress to get the total number of units at the end of the period. Then, all the costs for the current period are summed up and divided by the total number of units. This method is used for cases where there are slight fluctuations in costs from period to period or where there is no standard costing system. Let’s assume, a manufacturing business completed 4,000 products and has another 1,000 units halfway through production, the total costs would be divided by 4,500 units [i.e. If the total cost calculated across all departments to produce these units was $16,875, it means that the cost per unit will be determined by simply dividing the total cost of $16,875 by the 4,500 number of units. Hence, a process costing system is used to allocate costs to an individual unit after a process of mass production.

The costs added in each process during the current period is prorated to the production necessary to complete the opening work in progress, to complete the units added in the process and units in the work in progress. You cannot calculate the total output of the period by just taking the sum of completed units and work in process (ending inventory) because units in the work-in-process inventory are not 100% complete. A student's first thought is that this is easy—just divide the total cost by the number of units produced. The institute of cost and management accountants (icma) defines costing as the technique and process of ascertaining costs.

Process costing and job order costing are both acceptable methods for tracking costs and production levels. Some companies use a single method, while some companies use both, which creates a hybrid costing system. The system a company uses depends on the nature of the product the company manufactures. In the case of a not-for-profit company, the same process could be used to determine the average costs incurred by a department that performs interviews. The department’s costs would be allocated based on the number of cases processed.
