4 4: Compute a Predetermined Overhead Rate and Apply Overhead to Production Business LibreTexts

The period selected tends to be one year, and you can use direct labor costs, hours, machine hours or prime cost as the allocation base. The production head wants to calculate a predetermined overhead rate, as that is the main cost allocated to the new product VXM. Traditionally, overheads have been absorbed in the product cost based on a single basis of apportionment. For instance, in a labor-intensive environment, labor hours were used to absorb overheads. On the other hand, the machine hours were used to absorb overheads in a machine incentive environment.

Advantage of using pre-determined overheads

• So, if a higher activity level is forecasted in the accounting period, lower overheads can be estimated and vice versa.
• Businesses normally face fluctuation in product demand due to seasonal variations.
• That is, the company is now aware that a 5-hour job, for instance, will have an estimated overhead cost of $100.
• In the absence of predetermined overhead rates, the business cannot compare actual expenses with any standard and, thus, cannot evaluate its actual performance.
• Predetermined overhead rates are important because they provide a way to allocate overhead costs to products or services.
• This rate is used to allocate or apply overhead costs to products or services.
• Variances can be calculated for actual versus budgeted or forecasted results.

However, for most businesses waiting until the product has been produced to determine its costs may virtual accountant not be an option. The material and labor costs are easy to predict as these can be calculated using estimated usage of material and labor per product multiplied with the expected rate of usage per unit of the product. However, the business may face problems when trying to determine the overhead cost per unit. It’s calculated by obtaining budgeted cost and level of activity, and it’s preferred over actual overheads because estimates can include seasonal variations and other estimates.

How To Calculate

• Use the following data for the calculation of a predetermined overhead 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.
• Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing.
• Another way to view it is overhead costs are those production costs that are not categorized as direct materials or direct labor.
• Instead of using the numbers of units to be produced, the business may also choose another activity base such as labor hours or machine hours that are needed to meet the estimated level of activity.

First, you need to figure out which overhead costs are involved, and then create a total of this amount. If you have a large company, you may need to determine an allocation base for each department. Following this, you can assess which costs are similar and therefore which allocation base they belong to.

• In this article, we will discuss the formula for predetermined overhead rate and how to calculate it.
• The overhead used in the allocation is an estimate due to the timing considerations already discussed.
• Both figures are estimated and need to be estimated at the start of the project/period.
• 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.
• Shaun Conrad is a Certified Public Accountant and CPA exam expert with a passion for teaching.
• The third step is to compute the predetermined overhead rate by dividing the estimated total manufacturing overhead costs by the estimated total amount of cost driver or activity base.
• Understanding your company’s finances is an essential part of running a successful business.

Now, let’s look at some hypothetical business models to see actual use-cases for predetermined overhead rates. The use of such a rate enables an enterprise to determine the approximate total cost of each job when completed. In recent years increased automation in manufacturing operations has resulted in a trend towards machine hours as the activity base in the calculation. A Predetermined Overhead rate shall be used to calculate an estimate on the projects that are yet to commence for overhead costs. It would involve calculating a known cost (like Labor cost) and then applying an overhead rate (which was predetermined) to this to project an unknown cost (which is the overhead amount).

How do I know if a cost is overhead or not?

Predetermined overhead rates are important because they provide a way to allocate overhead costs to products or predetermined overhead rate formula services. 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.

• The most prominent concern of this rate is that it is not realistic being that it is based on estimates.
• In a company, the management wants to calculate the predetermined overhead to set aside some amount for the allocation of a cost unit.
• So if your business is selling more products, you’ll still be paying the same amount in rent.
• For example, let’s say the marketing agency quotes a client $1,000 for a project that will take 10 hours of work.

Calculating Manufacturing Overhead Cost for an Individual Job

The formula for calculating Predetermined Overhead Rate is represented as follows. Overheads have been absorbed in normal balance the product cost traditionally using machine and labour hours. However, modern absorption requires the use of multiple bases to enhance the accuracy of the process.
