Job Costing vs Process Costing

Process Costing

Process costing entails handing off accumulated costs from one department to the next. For companies that make large volumes of homogeneous products, process costing is much simpler than job costing. It also enables companies to hone in on the cost of each stage in the manufacturing process and look for ways to reduce cost if necessary. Process costing can be time consuming, and it can be difficult to accurately assign product costs to each manufacturing stage and to work-in-progress items.

The main difference between the two methods is that they treat the opening stock of WIP in a different way. An example of parallel processing is provided below. An example of sequential processing is provided below. If there is any by-product in any process and the by-product has any sale price or market price then it is shown on the credit of the process concerned.

Why do we need to allocate total product costs to units of product?

Remember, this is accounting; we are recording and reporting on costs, and trying to have the costs parallel the actual flow of production through the manufacturing process. When 2 or more items are created using the same method, the joint expenses are divided among them according to some weight, such as several points. Point-based weighting is a subjective choice that will result in approximative cost and cannot be relied upon.

  • By understanding how much it costs to produce a product at each stage, companies can make changes to their production process in order to save money and become more efficient.
  • Thus, element wise breakdown of cost into material, labour and overheads is absolutely necessary.
  • In operation costing, each operation is treated as a cost centre and the costs are accumulated for each operation instead of each process.
  • For the purpose of dealing with the stocks of finished goods, a separate Process Stock Account is prepared with each process.
  • For example, in a job order cost system, each job is unique, which allows management to establish individual prices for individual projects.

Products with a cost of $6,400 are transferred from the Rolling department to the Packaging department. Products with a cost of $5,500 are transferred from the Mixing department to the Rolling department.

The total conversion costs are divided by 400 to calculate the conversion costs per unit. To calculate total cost per unit, the materials cost per unit is added to the conversion cost per unit. Process Costing The raw materials are assigned based on material requisition forms, the labor based on time tickets, and the overhead based on predetermined overhead rates based on direct labor dollars.

Process Costing

Process costing is an accounting method deployed when there is mass production of similar products by collecting and assigning manufacturing costs to the units produced. Process costing in accounting is a system that is used to track the costs of production at each stage. This information is then used to calculate the cost per unit of output. One way to reduce the cost per unit of output is to increase the efficiency of the production process. This can be done by reducing the amount of waste, increasing the utilization of resources, and improving the quality of the product.

The process account may be ruled with an additional column to show the unit cost. In some cases, the entire output of a process may not be transferred to the subsequent process and a part of it may be held in the processing department in its finished form.
