4 4 Compute a Predetermined Overhead Rate and Apply Overhead to Production Principles of Accounting, Volume 2: Managerial Accounting

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.

• For these reasons, most companies use predetermined overhead rates rather than actual overhead rates in their cost accounting systems.
• A number of possible allocation bases are available for the denominator, such as direct labor hours, direct labor dollars, and machine hours.
• 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.
• So, predetermined overhead rates are an important tool for the organization to assess their performances quickly and take corrective measures.
• The business world is dynamic, and the production environment is getting complex day by day.
• Predetermined Overhead Rate Calculators are essential tools for cost accountants, financial analysts, and business managers.
• Once the total overheads are estimated, the organization needs to identify the base unit used for allocating overheads.

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. 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.

Estimated Total Manufacturing Overhead Costs

From the above list, salaries of floor managers, factory rent, depreciation and property tax form part of manufacturing overhead.

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. The predetermined overhead rate is based on anticipation and certain historical data. The person involved in preparing and finalizing overhead rates must have an eye for detail and an in-depth understanding of products and the manufacturing process within the organization. Also, any change in the product line, raw material, or any deviation from previous processes must be taken into consideration before the finalization of predetermined overhead rates.

Calculation of Predetermined Overhead and Total Cost under Traditional Allocation

Therefore, the predetermined overhead rate of TYC Ltd for the upcoming year is expected to be $320 per hour. There are several concerns with using a predetermined overhead rate, which include are noted below. Following are some of the disadvantages of using a predetermined overhead rate. Overheads have been absorbed in the product cost traditionally using machine and labour hours. However, modern absorption requires the use of multiple bases to enhance the accuracy of the process.

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 https://www.bookstime.com/ to dry, crush, and roast the nuts changes depending on the moisture content of the nuts upon arrival. Cost accountants want to be able to estimate and allocate overhead costs like rent, utilities, and property taxes to the production processes that use these expenses indirectly.

Examples of Predetermined 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. 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 predetermined overhead rate 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. As a result, two identical jobs, one completed in the winter and one completed in the spring, would be assigned different manufacturing overhead costs.

It’s useful in cost accounting as product costing can only be obtained once overheads are absorbed in the cost of the product. 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. There are concerns that the rate may not be accurate, as it is based on estimates rather than actual data. In addition, changes in prices and industry trends can make historical data an unreliable predictor of future overhead costs. Finally, using a predetermined overhead rate can result in inaccurate decision-making if the rate is significantly different from the actual overhead cost.
