The predetermined overhead rate calculation shown in the example above is known as the single predetermined overhead rate or plant-wide overhead rate. This example helps to illustrate the predetermined overhead rate calculation. Departmental overhead rates are needed because different processes are involved in production that take place in different departments. Small companies typically use activity-based costing, while large organizations will have departments that compute their own rates. Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing.

The standard overhead rate is the total budgeted overhead of $10,000 divided by the level of activity (direct labor hours) of 2,000 hours. Notice that fixed overhead remains constant at each of the production levels, which of the following is the formula to compute the predetermined factory overhead rate? but variable overhead changes based on unit output. If Connie’s Candy only produced at 90% capacity, for example, they should expect total overhead to be $9,600 and a standard overhead rate of $5.33 (rounded).

The overhead used in the allocation is an estimate due to the timing considerations already discussed. 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. For example, the recipe for shea butter has easily identifiable quantities of shea nuts and other ingredients. Based on the manufacturing process, it is also easy to determine the direct labor cost. But determining the exact overhead costs is not easy, as the cost of electricity needed to dry, crush, and roast the nuts changes depending on the moisture content of the nuts upon arrival.

• The following equation is used to calculate the predetermined overhead rate.
• The predetermined overhead rate is then applied to production to facilitate determining a standard cost for a product.
• Start by testing each integer to see if and how often it divides 100 and the subsequent quotients evenly.
• If the outcome is favorable (a negative outcome occurs in the calculation), this means the company was more efficient than what it had anticipated for variable overhead.
• Estimating overhead costs is difficult because many costs fluctuate significantly from when the overhead allocation rate is established to when its actual application occurs during the production process.
• Actual factory overhead for the month was $9,000 and actual volume was 5,000 hours.
• Often, the actual overhead costs experienced in the coming period are higher or lower than those budgeted when the estimated overhead rate or rates were determined.

Formula for Predetermined Overhead Rate

As a result, management would likely view labor hours as the activity base when applying overhead costs. 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. Management analyzes the costs and selects the activity as the estimated activity base because it drives the overhead costs of the unit. It is often difficult to assess precisely the amount of overhead costs that should be attributed to each production process.

• Finally, using a predetermined overhead rate can result in inaccurate decision-making if the rate is significantly different from the actual overhead cost.
• To understand the whole process, first you must get familiar with what is a prime factor.
• Small companies tend to use activity-based costing, whereas in larger companies, each department in which different processes of production take place typically computes its own predetermined overhead rate.
• The standard overhead rate is calculated by dividing budgeted overhead at a given level of production (known as normal capacity) by the level of activity required for that particular level of production.

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. Figure 4.18 shows the monthly manufacturing actual overhead recorded by Dinosaur Vinyl. 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.

Suppose Connie’s Candy budgets capacity of production at 100% and determines expected overhead at this capacity. Connie’s Candy also wants to understand what overhead cost outcomes will be at 90% capacity and 110% capacity. The following information is the flexible budget Connie’s Candy prepared to show expected overhead at each capacity level. Companies need to make certain the sales price is higher than the prime costs and the overhead costs.

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

• Overhead costs are expenses that are not directly tied to production such as the cost of the corporate office.
• If the volume of goods produced varies from month to month, the actual rate varies from month to month, even though the total cost is constant from month to month.
• As a result, management would likely view labor hours as the activity base when applying overhead costs.
• A variable costing system allows companies to understand costs based on how much they are affected by sales volume.
• Departmental overhead rates are needed because different processes are involved in production that take place in different departments.
