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 borrow definition 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. 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.

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. Any difference between applied overhead and the amount of overhead actually incurred is called over- or under-applied overhead. As the production head wants to calculate the predetermined overhead rate, all the direct costs will be ignored, whether direct cost (labor or material).

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. 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.

Selecting an Estimated Activity Base

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. In these situations, a direct cost (labor) has been replaced by an overhead cost (e.g., depreciation on equipment). 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. To account for these changes in technology and production, many organizations today have adopted an overhead allocation method known as activity-based costing (ABC).

4 Compute a Predetermined Overhead Rate and Apply Overhead to 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. 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.

This allocation can come in the form of the traditional overhead allocation method or activity-based costing.. 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. Manufacturing overhead costs include all manufacturing costs except for direct materials and direct labor.

Until now, you have learned to apply overhead to production based on a predetermined overhead rate typically business boost centre 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. As a result, management would likely view labor hours as the activity base when applying overhead costs.

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. 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.

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 estimate is made at the beginning of an accounting period, before the commencement of any projects or specific jobs for which the rate is needed. A manufacturer producing a variety of products that require different processes will have multiple overhead rates known as departmental overhead rates instead of just one plant-wide overhead rate. Hence, this predetermined overhead rate of 66.47 shall be applied to the pricing of the new product VXM. The predetermined overhead rate calculation shown in the example above is known as the single predetermined overhead rate or plant-wide overhead rate.

  1. This calculator offers a straightforward way to estimate the predetermined overhead rate, making it easier for businesses to manage and allocate their manufacturing overhead costs effectively.
  2. All such information is provided solely for convenience purposes only and all users thereof should be guided accordingly.
  3. The rate is determined by dividing the fixed overhead cost by the estimated number of direct labor hours.
  4. After reviewing the product cost and consulting with the marketing department, the sales prices were set.
  5. This activity base is often direct labor hours, direct labor costs, or machine hours.

Commonly, the manufacturing overhead cost for machine hours can be ascertained from the predetermined overhead rate in the manufacturing industry. Further, it is stated that the reason for the same is that overhead is based on estimations and not the actuals. Calculating the Predetermined Overhead Rate (POR) is a critical step in cost accounting, particularly in the manufacturing sector. It involves estimating the manufacturing overhead costs that will be incurred over a specific period and then allocating those costs to the units produced during that period. 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.

Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing. 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. After reviewing the product cost and consulting with the marketing department, the sales prices were set. The sales price, cost of each product, and resulting gross profit are shown in Figure 6.6.

Therefore, the JKL’s predetermined manufacturing overhead rate for the new year will be $60 ($1,200,000/20,000) per production machine hour. A predetermined overhead rate is often an annual rate used to assign or allocate indirect manufacturing costs to the goods it produces. Manufacturing overhead is allocated to products for various reasons including compliance with U.S. accounting principles and income tax regulations. The common allocation bases are direct labor hours, direct labor cost, machine hours, and direct materials. As you have learned, the overhead needs to be allocated to the manufactured product in a systematic and rational manner.
