What is a predetermined overhead rate?

predetermined overhead rate example

This means that for every dollar of direct labor cost a production process uses, it will use $1.50 of overhead costs. The predetermined overhead rate formula is calculated by dividing the total estimated overhead costs for the period by the estimated activity base. Is considered to be a primary driver of overhead costs, and traditionally, direct labor hours or machine hours were used for it. For example, a production facility that is fairly labor intensive would likely determine that the more labor hours worked, the higher the overhead will be. As a result, management would likely view labor hours as the activity base when applying overhead costs. First, if predetermined overhead rates are based on budgeted activity, then the unit product cost will fluctuate depending on the budgeted level of activity for the period.

There are concerns that the rate may not be accurate, as it is based on estimates rather than actual data. In addition, changes in prices and industry trends can make historical data an unreliable predictor of future overhead costs. Finally, using a predetermined overhead rate can result in inaccurate decision-making if the rate is significantly different from the actual overhead cost. The predetermined overhead rate computed above is known as single or plant-wide overhead rate which is mostly used by small companies. In large ones, each production department computes its own rate to apply overhead cost. The use of multiple predetermined overhead rates may be a complex and time consuming task but is considered a more accurate approach than applying only a single plant-wide rate.

This difference is calculated at the end of the accounting period. It is known as either over-absorption or under-absorption of overheads. Total base units could be the number of units or labor hours etc. Calculate Albert’s predetermined overhead rate for the year 2021.

Total estimated overhead cost for the two product line is $700,000. I am looking for the predetermined manufacturing overhead rate for each department. I repeat that the estimated, not actual, manufacturing overhead is used to calculated predetermined https://www.bookstime.com/ overhead. The predetermined overhead rate as calculated above is a plant-wide overhead rate or a single predetermined overhead rate. Applying the percentage conversion, we see Bob’s total overhead costs with regard to sales are 25%.


Reduces indirect expenses in several important areas by eliminating the need for paper-based workflows. Fixed costs are those expenses unaffected by changes in production levels. One of the most common examples is rent, which remains static no matter how many goods are produced.

This method is used when expenses exist but there is no direct expected benefit. For example, research and development costs are necessary expenses but cannot be traced to a specific product, so they are expensed as incurred. The company’s cars will be sold locally and export to a foreign country. And the total estimated sales for the whole year would be 500,000 Units. If there are no significant changes, the Predetermined Overhead Rate will be kept for use in the following year. The rate is calculated based on the assumption, and mostly there is small material that we could not avoid.

The Struggles of Private Company Accounting

Prior to the start of the accounting year, JKL Corp calculates the predetermined annual overhead rate to be used in the new year. JKL’s profit plan for the new year includes $1,200,000 as the budgeted amount of manufacturing overhead. JKL allocates the manufacturing overhead based on the normal and expected number of production machine hours which are 20,000 for the new year. Therefore, the JKL’s predetermined manufacturing overhead rate for the new year will be $60 ($1,200,000/20,000) per production machine hour.
