Job Costing

Job costing is a method used when a company produces unique products or services based on specific customer orders. Each job is treated as a separate cost object, and costs are accumulated for each job separately. The main characteristics of job costing include:

  • Unique products or services
  • Specific customer orders
  • Costs are traceable to individual jobs
  • Used in industries such as construction, printing, and custom manufacturing

Calculating Job Costs

To calculate the cost of a job, follow these steps:

  1. Identify and assign direct materials costs to the job.
  2. Identify and assign direct labor costs to the job.
  3. Allocate manufacturing overhead costs to the job using a predetermined overhead rate.
  4. Sum up the direct materials, direct labor, and allocated overhead costs to determine the total cost of the job.

Process Costing

Process costing is a method used when a company produces homogeneous products in a continuous process. Costs are accumulated for each process or department and then assigned to the products that pass through them. The main characteristics of process costing include:

  • Homogeneous products
  • Continuous production process
  • Costs are accumulated by process or department
  • Used in industries such as oil refining, chemical processing, and food processing

Calculating Process Costs

To calculate process costs, follow these steps:

  1. Determine the total costs (direct materials, direct labor, and manufacturing overhead) for each process or department.
  2. Calculate the equivalent units of production for each process or department.
  3. Compute the cost per equivalent unit for each cost category (direct materials, direct labor, and manufacturing overhead).
  4. Assign costs to the units completed and transferred out, and to the units remaining in work-in-process inventory.

Common Questions and Answers

What is the main difference between job costing and process costing?

Job costing is used for unique products or services based on specific customer orders, while process costing is used for homogeneous products produced in a continuous process.

When should a company use job costing instead of process costing?

A company should use job costing when it produces unique products or services based on specific customer orders, and when the costs can be easily traced to individual jobs. Examples include custom furniture manufacturers, construction companies, and print shops.

How are overhead costs allocated in job costing and process costing?

In job costing, overhead costs are allocated to individual jobs using a predetermined overhead rate based on a cost driver, such as labor hours or machine hours. In process costing, overhead costs are allocated to each process or department and then assigned to the products that pass through them.
