Overhead Rate Meaning, Formula, Calculations, Uses, Examples

A company’s manufacturing overhead costs are all costs other than direct material, direct labor, or selling and administrative costs. Once a company has determined the overhead, it must establish how to allocate the cost. This allocation can come in the form of the traditional overhead allocation method or activity-based costing.. A predetermined overhead rate is calculated at the start of the accounting period by dividing the estimated manufacturing overhead by the estimated activity base. The predetermined overhead rate is then applied to production to facilitate determining a standard cost for a product.

Selecting an Estimated Activity Base

To calculate the predetermined overhead rate using direct labor costs, the estimated manufacturing overhead costs would be divided by the allocation base which would be, in this case, the direct labor costs. The result of this calculation will be the predetermined overhead rate based upon the direct labor costs. 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.

Direct Costs vs. the Overhead Rate

Unexpected expenses can be a result of a big difference between actual and estimated overheads. Also, if the rates determined are nowhere close to being accurate, the decisions based on those rates will be inaccurate, too. From the above list, salaries of floor managers, factory rent, depreciation and property tax form part of manufacturing overhead. For example, if ABC Manufacturing’s actual manufacturing overhead was $100,000 but their applied manufacturing overhead was only $60,000, they underapplied $40,000. Conversely, if the actual manufacturing overhead was $100,000 but their applied manufacturing overhead was $120,000, they overapplied by $20,000.

Predetermined Overhead Rate Formula

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. Prior to the start of the accounting year, JKL Corp calculates the predetermined annual overhead rate to be used in the new year. JKL’s profit plan for the new year includes $1,200,000 as the budgeted amount of manufacturing overhead.

In recent years increased automation in manufacturing operations has resulted in a trend towards machine hours as the activity base in the calculation. The difference between the actual and predetermined amounts of overhead could be charged to expense in the current period, which may create a material change in the amount of profit and inventory asset reported. This can be avoided to some extent by regularly adjusting the predetermined overhead rate to align with actual costs. 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. Overhead costs are incurred whether the company is producing a large or small quantity of products or services.

Departmental overhead rates are needed because different processes are involved in production that take place in different departments. The following exercise is designed to help students apply their knowledge of the predetermined overhead rate in a business scenario. Companies need to make certain the sales price is higher than the prime costs and the overhead costs. In some industries, the company has no control over the costs it must pay, like tire disposal fees.

• You and the other managers at XYZ, Inc. have reviewed the historical overhead rates within your division and found that there is a link between the amount spent on materials to make your product and the total overhead.
• In addition, changes in prices and industry trends can make historical data an unreliable predictor of future overhead costs.
• Overhead costs are expenses that are not directly tied to production such as the cost of the corporate office.
• The term “predetermined overhead rate” refers to the allocation rate that is assigned to products or job orders at the beginning of a project based on the estimated cost of manufacturing overhead for a specific period of reporting.
• Overhead costs are incurred whether the company is producing a large or small quantity of products or services.

Calculating Manufacturing Overhead Cost for an Individual Job

To ensure that the company is profitable, an additional cost is added and the price is modified as necessary. In this example, the guarantee offered by Discount Tire does not include the disposal fee in overhead and increases that fee as necessary. 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.

• You would then take the measurement of what goes into production for the same period.
• If a company prices its products so low that revenues do not cover its overhead costs, the business will be unprofitable.
• This can be avoided to some extent by regularly adjusting the predetermined overhead rate to align with actual costs.
• This is a particular concern in highly competitive industries where production rates may vary dramatically, based on the popularity of the latest round of product releases.
• To conclude, the predetermined rate is helpful for making decisions, but other factors should be taken into consideration, too.

• For example, if ABC Manufacturing’s actual manufacturing overhead was $100,000 but their applied manufacturing overhead was only $60,000, they underapplied $40,000.
• 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.
• Manufacturing overhead costs include all manufacturing costs except for direct materials and direct labor.
• For these reasons, most companies use predetermined overhead rates rather than actual overhead rates in their cost accounting systems.
• In this example, the guarantee offered by Discount Tire does not include the disposal fee in overhead and increases that fee as necessary.
