For ease and simplicity, a common absorption rate for overheads may be used across a factory for all jobs and units of production, irrespective of the department in which they were produced. Calculating the overhead rate begins with determining which expenses of the company can be classified as overhead costs. Once the specific costs have been identified, the sum of all the costs is divided by revenue in the corresponding period. Overhead expenses are generally fixed costs, meaning they’re incurred whether or not a factory produces a single item or a retail store sells a single product. Fixed costs would include building or office space rent, utilities, insurance, supplies, maintenance, and repair.
You would then take the measurement of what goes into production for the same period. So, if you were to measure the total direct labor cost for the week, the denominator would be the total weekly cost of direct labor for production that week. Finally, you would divide the indirect costs by the allocation measure to achieve how much in overhead costs for every dollar spent on direct labor for the week. As you’ve learned, understanding the cost needed to manufacture a product is critical to making many management decisions (Figure 6.2). Knowing the total and component costs of the product is necessary for price setting and for measuring the efficiency and effectiveness of the organization. Remember that product costs consist of direct materials, direct labor, and manufacturing overhead.

To calculate the overhead rate, divide the indirect costs by the direct costs and multiply by 100. If the manufacturer uses a plant-wide manufacturing overhead rate, it would divide its expected total manufacturing overhead for the upcoming year by the expected total machine hours for the upcoming year. Let’s assume that the resulting plant-wide manufacturing overhead rate will be $30 per machine hour.
Direct Costs vs. the Overhead Rate
The equation for the overhead rate is overhead (or indirect) costs divided by direct costs or whatever you’re measuring. Direct costs typically are direct labor, cash flow vs profit direct machine costs, or direct material costs—all expressed in dollar amounts. Each one of these is also known as an « activity driver » or « allocation measure. »
- This allocation can come in the form of the traditional overhead allocation method or activity-based costing..
- Let’s compare these results to our single-rate computations by looking at the gross profit per unit.
- It is possible to have several overhead rates, where overhead costs are split into different cost pools and then allocated using different allocation measures.

Here, according to this method of overhead absorption, $5 per unit will be taken as factory overhead. Therefore, it becomes necessary to charge overheads to the cost of products, jobs, and processes according to certain well-established norms and scientific reasoning. All products, jobs, or services pass through one or more producing cost centers. Overhead absorption is defined as the allotment of overheads to cost units. When the amount of overheads has been determined on the predetermined basis for each cost center, the next step is to charge it to production. Overhead rate is also known as the predetermined overhead rate when budgeted information is used to calculate it.
Everything You Need To Master Financial Modeling
This means that for every dollar of direct labor, Joe’s manufacturing company incurs $1.21 in overhead costs. If you’re using accounting software for your business, you can obtain this information directly from your financial statements or other system reports. If not, you’ll have to manually add your indirect expenses to calculate your overhead rate. Sometimes a single predetermined overhead rate causes costs to be misallocated. Understanding how to calculate your overhead costs can help you create efficient strategies for your business. Regularly reviewing overhead lets you identify areas of excess spending while comparing your overhead to sales and labor helps you make effective decisions about pricing and hiring.
Departmental overhead rate definition
A departmental overhead rate is a standard charge based on the units of activity produced by a business segment. Overhead rates at the departmental level are usually applied in a more refined cost allocation environment, where there is a need to apply overhead costs as precisely as possible. Most organizations do not use departmental overhead rates, preferring instead to apply a simpler factory-wide overhead rate. Running a business requires a variety of expenses to create your product or service, but not all of them will directly contribute to generating revenue.
Assigning overheads to departments ensures that all jobs and Units of Production are charged with their fair share of overheads. Allocating overheads to jobs or units refers to assigning expenses to the job or unit that causes them. Fixed overhead costs are overhead costs that don’t change in relation to your production output. This could be something like rent that will stay the same even if your business activity fluctuates.
Allocating Based on Direct Labor
The application of multiple overhead absorption rates depend on two factors viz., the degree of accuracy desired and the clerical cost involved. In such cases departmental overhead absorption of respective departments is applied to the jobs or units depending on the time spent in each department instead of single overhead absorption rate. Under this method, total direct labor hours are used to determine the overhead absorption rate. An overhead rate, in managerial accounting, is an additional cost added on to the direct costs of production in order to more accurately assess the profitability of each product.
Blanket absorption rate is used in relation to the recovery or absorption of overheads. Suppose a manufacturing company is trying to determine its overhead rate for the past month. If our calculations are correct, we should be allocating all $188,000 of the overhead based on two rates instead of one.

For example, if a company makes bread, different departmental rates could be used for the actual production/manufacturing line and the bagging process. Of course, management also has to price the product to cover the direct costs involved in the production, including direct labor, electricity, and raw materials. A company that excels at monitoring and improving its overhead rate can improve its bottom line or profitability.
This is because the overhead expenses are incurred uniformly across all the departments in the factory. The main benefit of using a blanket absorption rate is that it is simple and easy to calculate. Therefore, measuring how much overhead should be applied to different units produced is very challenging.
