Types of Costs Involved in Job Order Costing
In Job order costing different – different type of costs are involved which are mainly divided into below three categories:
- Direct Material – Direct materials are the major contributor to job order costing.

These costs are completely depending on the quality and quantity of finished goods.
- Direct Labor – In Job order costing cost of labor used in a specific job is identified and added to the cost of production. Direct labor cost is calculated on the basis of no. of manpower and no. of hours worked. If the specific job is related to providing service then direct labor cost is comprised almost 80% – 90% of the total cost.
- Overhead – Overhead costs are those cost which is incurred in the manufacturing of a product or providing service other than the direct labor and direct material like Rent, Electricity, Depreciation, Legal Fees and any other. Some overhead costs are variable and some are fixed.

Let’s take an example of job order costing system.
Notebook Inc is a printing & stationery company who has received an order of 5000 copies of invoices from one of its customer according to the specification provided by the customer as on 1st aug’19 and notebook inc has to deliver the invoice copy on or before 20th aug’19 to its customer. As per the company, they are able to finish the work within 10 days, therefore, they have started on 5th aug’19 and assigned this work as a job no. 10/2019. In completion of this job below cost has been incurred by the company.
Direct Materials: In Production of one copy of invoice two units of raw material is required therefore for production of 5000 copies, 10000 units of raw material will be consumed which company has procured at different – different dates as per requirement. Initially, the cost of Raw material was $ 10 per unit but from 13th aug’19 it has increased by $ 1 because of a shortage of raw material in the market. The total cost of raw material consumed is $ 10500.
Direct Labor: In the production of one copy of invoice one manpower hour is required and cost of one manpower hour is $ 5 therefore for completion of job 5000 manpower hours has consumed which company has taken at different – different days according to the availability of raw material. The total cost of direct labor is $ 25000.
Manufacturing Overhead: Cost incurred by the company is $ 20000 which includes depreciation of plant and machinery, factory and office rent and other overheads consumed in the production of these 5000 copies of invoices.

- If two or jobs are going simultaneously then there is a chance of mistake as the cost of one job may be posted in another job.
- In job order costing overhead costs are based on estimates because it is difficult to know the overhead cost which is directly linked with the specific job because most of the overhead facilities are used for more than one job, therefore, there is a chance of excess/shortage allocation of cost.
