How to Calculate a Predetermined Overhead Rate OH: A Step-by-Step Guide

The management concern about how to find a predetermined overhead rate for costing. While predetermined overhead rates are widely used and needed for businesses, they may have some limitations. A business needs to estimate its total overheads for a period and estimate its total units or activity basis for the predetermined overhead rates. If these estimates are not accurate, they can end up causing a lot of problems for the business specially if decisions are based on the rates, such as pricing decisions.

Multiple or departmental predetermined overhead rates:

A company’s manufacturing overhead costs are all costs other than direct bookkeeping 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..

Using a Single Rate for Different Departments

Once the units to be produced or activity base has been estimated, the business must then estimate its total manufacturing costs based on the number of units to be produced. Once both these estimates have been made, the business can calculate its predetermined overhead rate. The company’s budget shows an estimated manufacturing overhead cost of $16,000 for the forthcoming year.

Enforcing company-wide cost-saving policies around printing, travel, etc. further helps minimize overhead. Allocating overhead this way provides better visibility into how much overhead each department truly consumes. So the company would apply $5 of overhead cost to the cost of each unit produced.

Indirect costs are those that cannot be easily traced back to a specific product or service. For example, the office rent mentioned earlier can’t be directly linked to any one good or service produced by the business. If the actual overhead at the end of the Catch Up Bookkeeping accounting period is 1,575 the overhead is said to be under applied by 75 (1,500 – 1,575) as shown in the table below. Using small business accounting software centralizes overhead tracking and analysis. Features like automated categorization and reporting provide real-time visibility into overhead costs. By factoring in overhead costs in this manner, the company arrives at a more accurate COGS.

In large ones, each production department computes its own rate to apply overhead cost. The use of multiple predetermined overhead rates may be a complex and time consuming task but is considered a more accurate approach than applying only a single plant-wide rate. According to a survey 34% of the manufacturing businesses use a single plant wide overhead rate, 44% use multiple overhead rates and rest of the companies use activity based costing (ABC) system. A predetermined overhead rate (OH) predetermined overhead rate is a critical calculation used by businesses to allocate manufacturing overhead costs to products or services.

Activity-Based Costing (ABC) Method

• It can be used to allocate overhead when calculating product costs and profits.
• Manufacturing operating expenses typically are comprised of machines, direct materials cost, direct labor hours and actual machine hours needed to manufacture a product.
• A company that excels at monitoring and improving its overhead rate can improve its bottom line or profitability.
• The single overhead rate method is a simplified approach that uses a single predetermined overhead rate for all overhead costs.
• Activities can be classified into different categories, such as setup, production, inspection, and shipping.
• Dinosaur Vinyl uses the expenses from the prior two years to estimate the overhead for the upcoming year to be $250,000, as shown in Figure 4.17.
• The equation for the overhead rate is overhead (or indirect) costs divided by direct costs or whatever you’re measuring.

This is why a predetermined overhead rate is computed to allocate the overhead costs to the production output in order to determine a cost for a product. The predetermined overhead rate is, therefore, usually used for contract bidding, product pricing, and allocation of resources within a company, based on each department’s utilization of resources. The company needs to use predetermined overhead rate to calculate the cost of goods sold and inventory balance.
