Predetermined Overhead Rate

Examples can include labor hours incurred, labor costs paid, amounts of materials used in production, units produced, or any other activity that has a cause-and-effect relationship with incurred costs. 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. Overhead costs are expenses that are not directly tied to production such as the cost of the corporate office.

As the predetermined overhead rate is an estimate of what the company believes will be the cost for manufacturing the product, the actual costs could be different than what they estimated. When the predetermined overhead rate is not exactly what the company estimated, the rate would be either overapplied or underapplied. This is determined by applying the actual costs of manufacturing, once known, against the estimated manufacturing costs, and the difference will determine if the predetermined overhead rate was overapplied or underapplied.

What is predetermined overhead rate?

The predetermined overhead rate is set at the beginning of the year and is calculated as the estimated (budgeted) overhead costs for the year divided by the estimated (budgeted) level of activity for the year. This activity base is often direct labor hours, direct labor costs, or machine hours. Once a company determines the overhead rate, it determines the overhead rate per unit and adds the overhead per unit cost to the direct material and direct labor costs for the product to find the total cost.

While it may become more complex to have different rates for each department, it is still considered more accurate and helpful because the level of efficiency and precision increases. Let’s take an example to understand the calculation of Predetermined Overhead Rate in a better manner.

Predetermined Overhead Rate (POHR): Formula and Calculation

The predetermined overhead rate can be either overapplied or underapplied, depending on how accurate the company estimated the manufacturing overhead. The manufacturing overhead could be spread across all three accounts to be more accurate, but this is more time consuming. The limitations and problems of the predetermined overhead rate are that they are not always realistic, accurate decision-making https://www.bookstime.com/ can be affected, and historical costs do not always match current costs. This is related to an activity rate which is a similar calculation used in Activity-based costing. A pre-determined overhead rate is normally the term when using a single, plant-wide base to calculate and apply overhead. Overhead is then applied by multiplying the pre-determined overhead rate by the actual driver units.

Adam received his master’s in economics from The New School for Social Research and his Ph.D. from the University of Wisconsin-Madison in sociology. He currently researches and teaches economic sociology and the social studies of finance at the Hebrew University in Jerusalem. She enjoys writing in these fields to educate predetermined overhead rate formula and share her wealth of knowledge and experience. Based on this result, Bob’s spending $0.25 on overhead for every dollar he earns in sales. We saved more than $1 million on our spend in the first year and just recently identified an opportunity to save about $10,000 every month on recurring expenses with Planergy.

• The most prominent concern of this rate is that it is not realistic being that it is based on estimates.
• One of the advantages of predetermined overhead rate is that businesses can use it to help with closing their books more quickly.
• Direct costs are costs directly tied to a product or service that a company produces.
• As a result, there is a high probability that the actual overheads incurred could turn out to be way different than the estimate.
• That means it represents an estimate of the costs of producing a product or carrying out a job.
• In this article, we will discuss the formula for predetermined overhead rate and how to calculate it.

Since both the numerator and denominator of the calculation are comprised of estimates, it is possible that the result will not bear much resemblance to the actual overhead rate. To keep this from being an issue, base the estimates on recent actual history, adjusted for your best estimate of production activity in the near future. The predetermined rate is based on estimates before the accounting period begins and is held constant throughout the period.
