Estimating overhead costs is difficult because many costs fluctuate significantly from when the overhead allocation rate is established to when its actual application occurs during the production process. You can envision the potential problems in creating an overhead allocation rate within these circumstances. A predetermined overhead rate is calculated at the start of the accounting period by dividing the estimated manufacturing overhead by the estimated activity base.

Any type of business can benefit from job costing, from construction companies to accounting firms. Accounting software can help you keep track of receipts, stay on track with your financial goals, and ensure you are getting paid what you are worth.

If the actual overhead at the end of the accounting period is 1,575 the overhead is said to be over applied by 25 (1,600 – 1,575). Again the actual overhead at the end of the accounting period is 1,575 and the overhead is said to be under applied by 81 (1,494 – 1,575) as shown below.

The overhead rate allocates indirect costs to the direct costs tied to production by spreading or allocating the overhead costs based on the dollar amount for direct costs, total labor hours, or even machine hours. Now that you’ve calculated your predetermined overhead rate, you can apply it to jobs for the purpose of job costing as the applied overhead cost. If a job is in work in process and has recorded actual direct labor hours of 600 during an accounting period then the predetermined overhead applied to the job is calculated as follows. If the predetermined overhead rate calculated is nowhere close to being accurate, the decisions based on this rate will definitely be inaccurate, too.
