How to Calculate a Predetermined Overhead Rate
Hence, it is essential to use rates that determine how much of the overhead costs are applied to each unit of production output. This is why a predetermined overhead rate is computed to allocate the overhead costs to the production output in order to determine a cost for a product. The predetermined overhead rate is, therefore, usually used for contract bidding, product pricing, and allocation of resources within a company, based on each department’s utilization of resources. In production, the predetermined overhead rate is computed to facilitate the determination of the standard cost for a product. That is, a certain amount of manufacturing overhead is applied to job orders or products which is used to estimate future manufacturing costs. Predetermined overhead rate is an allocation rate that is used in manufacturing, applying an estimated manufacturing overhead to specific periods or jobs.
- In accounting, a predetermined overhead rate is an allocation rate that applies a specific amount of manufacturing overhead to services or products.
- One of the advantages of predetermined overhead rate is that businesses can use it to help with closing their books more quickly.
- In this article, we will discuss the formula for predetermined overhead rate and how to calculate it.
- Keeping proper financial records is time-intensive and small mistakes can be costly.
A good rule of thumb is to ask yourself if the cost will be incurred regardless of how much product you’re making. A bookkeeping expert will contact you during business hours to discuss your needs. Harold Averkamp (CPA, MBA) has worked as a university accounting instructor, accountant, and consultant for more than 25 years. Dinosaur Vinyl uses the expenses from the prior two years to estimate the overhead for the upcoming year to be $250,000, as shown in Figure 4.17. A financial professional will offer guidance based on the information provided and offer a no-obligation call to better understand your situation.
As a result, the overhead costs that will be incurred in the actual production process will differ from this estimate. The activity base (also known as the allocation base or activity driver) in the formula for predetermined overhead rate is often direct labor costs, direct labor hours, or machine hours. That is, a number of possible allocation bases such as direct labor hours, direct labor dollars, or machine hours can be used for the denominator of the predetermined overhead rate equation.
The estimate will be made at the beginning of an accounting period, before any work has actually taken place. Predetermined overhead is an estimated rate used by the business to absorb overheads in the product cost, and it’s calculated by dividing overheads by the budgeted level of activity. Both figures are estimated and need to be estimated at the start of the project/period. A predetermined overhead rate is used by businesses to absorb the indirect cost in the cost card of the business. Further, this rate is calculated by dividing budgeted overheads by the budgeted level of activity.
Characteristics of the predetermined overhead rate
The predetermined overhead rate is then applied to production to facilitate determining a standard cost for a product. Let us take the example of ort GHJ Ltd which has prepared the budget for next year. The company estimates a gross profit of $100 million on profit and loss questions total estimated revenue of $250 million. As per the budget, direct labor cost and raw material cost for the period is expected to be $40 million and $60 million respectively. The company uses machine hours to assign manufacturing overhead costs to products.
A predetermined overhead rate is achieved by first estimating the total cost of the activity base, which is typically the total cost of labor hours, machine hours, and similar. Secondly, the total manufacturing overhead cost is estimated for the specific period of activity, order, or job. This figure is the sum of costs of the entirety of resources expended during the specific period. This is achieved by dividing the manufacturing overhead cost by the activity base. For example, if a manufacturing business estimates it has $12,000 in overhead costs and a $15,000 activity, the predetermined overhead rate is $0.80. This rate can now be deployed by the business to help them determine the estimated total cost of each job when completed.
Therefore, the predetermined overhead rate of GHJ Ltd for next year is expected to be $5,000 per machine hour. Therefore, the predetermined overhead rate of TYC Ltd for the upcoming year is expected to be $320 per hour. This predetermined overhead rate can also be used to help the marketing agency estimate its margin on a project. Then, they’ll need to estimate the amount of activity or work that will be performed in that same time period.

Implementation of ABC requires identification and record maintenance for various overheads. This record maintenance and cost monitoring is expected to increase the administrative cost. So, the businesses need to do a cost-benefit analysis before implementing the ABC system of costing. On the other hand, if the business wants to use actual overheads, it has to wait for the end of the month and get invoices in hand. So, it may not be a good idea with perspective to effective business management. It’s a completely estimated amount that changes with the change in the level of activity.
The rate avoids collecting actual manufacturing overhead costs as part of the closing period. In accounting, a predetermined overhead rate is an allocation rate that applies a specific amount of manufacturing overhead to services or products. Typically, accountants estimate predetermined overhead at the beginning of each reporting period. Using the planned annual amounts for the upcoming year reduces the fluctuations that would occur if monthly rates were used. In order to find the overhead rate we will use the same basis that we have chosen by multiplying this basis by the calculated rate.

This means that once a business understands the overhead costs per labor hour or product, it can then set accurate pricing that allows it to make a profit. Hence, one of the major advantages of predetermined overhead rate formula is that it is useful in price setting. Therefore, in simple terms, the POHR formula can be said to be a metric for an estimated rate of the cost of manufacturing a product over a specific period of time.
Sales and production decisions based on this rate could be faulty
This information is then used to calculate an overhead rate per unit of production. The predetermined overhead rate is used to price new products and to calculate variances in overhead costs. Of course, management also has to price the product to cover the direct costs involved in the production, including direct labor, electricity, and raw materials. A company that excels at monitoring and improving its overhead rate can improve its bottom line or profitability. The overhead rate has limitations when applying it to companies that have few overhead costs or when their costs are mostly tied to production.
Examples of Predetermined Overhead Rate
In more complicated cases, a combination of several cost drivers may be used to approximate overhead costs. For this, you can take the average manufacturing overhead cost for the previous three months, and divide this by the machine hours in the current month. If you then find out later that in fact the actual amount that should have been assigned is $36,000 dollars, then the $4000 dollar difference should be charged to the cost of goods sold.
This allocation process depends on the use of a cost driver, which drives the production activity’s cost. 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. Sales of each product have been strong, and the total gross profit for each product is shown in Figure 6.7.
