Overhead Rate Meaning, Formula, Calculations, Uses, Examples

As a result, two identical jobs, one completed in the winter and one completed in the spring, would be assigned different manufacturing overhead costs. To avoid such fluctuations, actual overhead rates could be computed on an annual or less-frequent basis. However, if the overhead rate is computed annually based on the actual costs and activity for the year, the manufacturing overhead assigned to any particular job would not be known until the end of the year.

• Management analyzes the costs and selects the activity as the estimated activity base because it drives the overhead costs of the unit.
• The use of predetermined overheads effectively incorporates the cost effects of seasonal variations in the product cost and price.
• Implementation of ABC requires identification and record maintenance for various overheads.
• 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 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.
• So, the businesses need to do a cost-benefit analysis before implementing the ABC system of costing.
• Businesses normally face fluctuation in product demand due to seasonal variations.

1 Calculate Predetermined Overhead and Total Cost under the Traditional Allocation Method

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. 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. Direct costs are costs directly tied to a product or service that a company produces. Direct costs include direct labor, direct materials, manufacturing supplies, and wages tied to production.

Calculating Manufacturing Overhead Cost for an Individual Job

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. Common activity bases used in the calculation include direct labor costs, direct labor hours, or machine hours. 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. Added to these issues is the nature of establishing an overhead rate, which is often completed months before being applied to specific jobs.

Overhead Rate Meaning, Formula, Calculations, Uses, Examples

A predetermined overhead rate, also known as a plant-wide overhead rate, is a calculation used to determine how much of the total manufacturing overhead cost will be attributed to each unit of product manufactured. The rate is determined by dividing the fixed overhead cost by the estimated number of direct labor hours. For example, the total direct labor hours estimated for the solo product is 350,000 direct labor hours. With $2.00 of overhead per direct hour, the Solo product is estimated to have $700,000 of overhead applied. When the $700,000 of overhead applied is divided by the estimated production of 140,000 units of the Solo product, the estimated overhead per product for the Solo product is $5.00 per unit. The computation of the overhead cost per unit for all of the products is shown in Figure 6.4.

• Because of this decrease in reliance on labor and/or changes in the types of production complexity and methods, the traditional method of overhead allocation becomes less effective in certain production environments.
• Product costing can be extremely helpful in managerial decision-making, and its prime use is related to product costing and job order costing.
• As explained previously, the overhead is allocated to the individual jobs at the predetermined overhead rate of $2.50 per direct labor dollar when the jobs are complete.
• A predetermined overhead rate is used by businesses to absorb the indirect cost in the cost card of the business.
• However, the problem with absorption/traditional costing is that we have to ignore individual absorption bases and absorb all overheads using a single level of activity.
• Departmental overhead rates are needed because different processes are involved in production that take place in different departments.

On the other hand, if the actual cost is more, an adjusting entry is passed to record the remaining cost in the business’s income statement.

• For instance, a business with a labor incentive environment absorbs the overhead cost with the labor hours.
• Manufacturing overhead costs include all manufacturing costs except for direct materials and direct labor.
• To ensure that the company is profitable, an additional cost is added and the price is modified as necessary.
• 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.
• A number of possible allocation bases are available for the denominator, such as direct labor hours, direct labor dollars, and machine hours.

What is your current financial priority?

The estimated or budgeted overhead is the amount of overhead determined during the budgeting process and consists of manufacturing costs but, as you have learned, excludes direct materials and direct labor. Examples of manufacturing overhead costs include indirect materials, indirect labor, manufacturing utilities, and manufacturing equipment depreciation. Another way to view it is overhead costs are those production costs that are not categorized as direct materials or direct labor. Until now, you have learned to apply overhead to production based on a predetermined overhead rate typically using an activity base. An 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.

If an actual rate is computed monthly or quarterly, seasonal factors in overhead costs or in the activity base can produce fluctuations in the overhead rate. For example, the costs of heating and cooling a factory in Illinois will be highest in the winter and summer months and lowest in the spring and fall. If the overhead rate is recomputed at the end of each month or each quarter based on actual costs and activity, the overhead rate would go up in the winter and summer and down in the spring and fall.

The controller of the Gertrude Radio Company wants to develop a predetermined overhead rate, which she can use to apply overhead more quickly in each reporting period, thereby allowing for a faster closing process. A later analysis reveals that the actual amount that should have been assigned to inventory is $48,000, so the $2,000 difference is charged to the cost of goods sold. Overhead costs are then allocated to production according to the use of that activity, such as the number of machine setups needed. In contrast, the traditional allocation method commonly uses cost drivers, such as direct labor or machine hours, as the single activity. So, if you wanted to determine the indirect costs for a week, you would total up your weekly indirect or overhead costs.

• A company’s manufacturing overhead costs are all costs other than direct material, direct labor, or selling and administrative costs.
• At the end of the year, the amount of overhead estimated and applied should be close, although it is rare for the applied amount to exactly equal the actual overhead.
• After reviewing the product cost and consulting with the marketing department, the sales prices were set.
• Once an overhead rate is calculated using the given formula, it’s absorbed in the cost card of the business using the actual level of the activity.

Finally, using a predetermined overhead rate can result in inaccurate decision-making if the rate is significantly different from the actual overhead cost. The common allocation bases are direct a single predetermined overhead rate is called a(n) labor hours, direct labor cost, machine hours, and direct materials. A predetermined overhead rate is used by businesses to absorb the indirect cost in the cost card of the business.
