What Predetermined Overhead Rate Is Formula and Sample

As you’ve learned, understanding the cost needed to manufacture a product is critical to making many management decisions (Figure 6.2). Knowing the total and component costs of the product is necessary for price setting and for measuring the efficiency and effectiveness of the organization. Remember that product costs consist of direct materials, direct labor, and manufacturing overhead.

Team at a large corporation, using this formula effectively can help you measure and refine your indirect spend.

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.

Overhead expenses are generally fixed costs, meaning they’re incurred whether or not a factory produces a single item or a retail store sells a single product. Fixed costs would include building or office space rent, difference between horizontal and vertical utilities, insurance, supplies, maintenance, and repair. Unless a cost can be directly attributable to a specific revenue-generating product or service, it will be classified as overhead, or as an indirect expense.

Because the predetermined overhead rate is based on estimates, calculating it with incomplete or inaccurate data can also skew the budgets, reports, and forecasts created using it. Let’s assume a company has overhead expenses that total $20 million for the period. The company has direct labor expenses totaling $5 million for the same period. The overhead rate is a cost added on to the direct costs of production in order to more accurately assess the profitability of each product. In more complicated cases, a combination of several cost drivers may be used to approximate overhead costs.

Predetermined Overhead Rate Formula

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. As previously mentioned, the predetermined overhead rate is a way of estimating the costs that will be incurred throughout the manufacturing process. That means it represents an estimate of the costs of producing a product or carrying out a job.

  • Converting this to a percentage, Bob has a manufacturing overhead rate of 89% with regard to direct labor costs.
  • The concept of predetermined overhead rate is very important because it is used most of the enterprises as it enables them to estimate the approximate total cost of each job.
  • To allocate overhead costs, an overhead rate is applied to the direct costs tied to production by spreading or allocating the overhead costs based on specific measures.
  • The predetermined overhead rate formula is calculated by dividing the total estimated overhead costs for the period by the estimated activity base.

The production hasn’t taken place and is completely based on forecasts or previous accounting records, and the actual overheads incurred could turn out to be way different than the estimate. The allocation base (also known as the activity base or activity driver) can differ depending on the nature of the costs involved. Applying the percentage conversion, we see Bob’s total overhead costs with regard to sales are 25%. In addition, without the proper analytical tools, it’s possible to rely too heavily on historical data that may not apply to current operating conditions and costs. A difference between estimated and actual costs creates a variance charged to the cost of goods sold.

Direct Costs vs. the Overhead Rate

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. Added to these issues is the nature of establishing an overhead rate, which is often completed months before being applied to specific jobs. Establishing the overhead allocation rate first requires management to identify which expenses they consider manufacturing overhead and then to estimate the manufacturing overhead for the next year.

Do you own a business?

When you determine all company’s manufacturing overhead costs, add them to get the total. The allocation of overhead to the cost of the product is also recognized in a systematic and rational manner. The overhead is then applied to the cost of the product from the manufacturing overhead account. The overhead used in the allocation is an estimate due to the timing considerations already discussed.

Total Machine Hours

The computation of the overhead cost per unit for all of the products is shown in Figure 6.4. Once calculated, this rate can be applied to future periods in order to predict and better understand the financial impact of overhead costs. It can also be used retroactively, to help assess the cost effectiveness of past productions. In either case, having a clear understanding of your company’s predetermined overhead rate can be helpful in making key decisions about pricing, production levels, and more. Sales of each product have been strong, and the total gross profit for each product is shown in Figure 6.7.

For example, the cost of Job 2B47 at Yost Precision Machining would not be known until the end of the year, even though the job will be completed and shipped to the customer in March. For these reasons, most companies use predetermined overhead rates rather than actual overhead rates in their cost accounting systems. 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.

The predetermined overhead rate formula is a useful resource for businesses planning for the future. Larger businesses may even wish to calculate different rates for specific departments, which can encourage even higher levels of accuracy by employing even greater levels of precision across the business. However, it should not be forgotten that calculating the rate can potentially be a considerable task and is likely to add to the cost of required accounting labor itself. When numerous factors are taken into consideration, a predetermined overhead rate can be an instructive instrument for manufacturing businesses.

Overhead Rate Formula and Calculation

This rate is frequently used to assist in closing the books more quickly, since it avoids the compilation of actual manufacturing overhead costs as part of the period-end closing process. However, the difference between the actual and estimated amounts of overhead must be reconciled at least at the end of each fiscal year. Once you’ve identified and calculated your total indirect expenses, it’s time to choose an overhead allocation method so you can properly contextualize the results and make the right strategic decisions.
