4 3: Departmental rates to estimate factory overhead Business LibreTexts

The overhead rate has limitations when applying it to companies that have few overhead costs or when their costs are mostly tied to production. Also, it’s important to compare the overhead rate to companies within the same industry. A large company with a corporate office, a benefits department, and a human resources division will have a higher overhead rate than a company that’s far smaller and with less indirect costs.

• Once the specific costs have been identified, the sum of all the costs is divided by revenue in the corresponding period.
• Each one of these is also known as an “activity driver” or “allocation measure.”
• If you used direct labor hours to calculate the rate, use actual direct labor hours.
• To fully understand the overhead rate, you should first be comfortable with the following accounting terms.
• Dan advises clients on strategic planning, federal and state tax issues, transactional matters, and employee benefits.

The predetermined overhead rate is set at the beginning of the year and is calculated as the estimated (budgeted) overhead costs for the year divided by the estimated (budgeted) level of activity for the year. 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.

Cost-cutting, efficiency and productivity are standard elements of a strong corporate performance methodology. Analysis and benchmarking of departmental overhead rates is an effective way to measure success. Comparisons between competitors, as well as among various internal departments help isolate efforts that are adding value, and those that are destroying enterprise value. The departmental overhead rate is specific to every segregated step in the entire process. For example, if a company makes bread, different departmental rates could be used for the actual production/manufacturing line and the bagging process. The single overhead absorption rate is not appropriate where there are number of departments in the factory and jobs do not spend an equal amount of time in each department.

• Sales of each product have been strong, and the total gross profit for each product is shown in Figure 6.7.

• Direct costs are costs directly tied to a product or service that a company produces.
• This means that for every dollar of direct labor, Joe’s manufacturing company incurs $1.21 in overhead costs.

During that same month, the company logs 30,000 machine hours to produce their goods. Sometimes a single predetermined overhead rate causes costs to be misallocated. When all the jobs or Units of Production pass through all the departments in a factory, it is appropriate to use a blanket absorption rate.

Advantages & Disadvantages of Job Order Costing & Process Costing

Remember that product costs consist of direct materials, direct labor, and manufacturing overhead. A company’s manufacturing overhead costs are all costs other than direct 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..

Why You Need To Know Your Overhead Rate

In spite of not being attributable to a specific revenue-generating component of a company’s business model, overhead costs are still necessary to support core operations. Although our information is becoming more detailed and sophisticated, and we hope more accurate, we still have one more option, Activity-Based Costing (ABC), which may give us yet more insight. However, before you tackle ABC, check your understanding of allocating fixed manufacturing overhead using multiple departmental rates.

What Does the Departmental Overhead Rate Tell You?

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. Unless a cost can be directly attributable to a specific revenue-generating product or service, it will be classified as overhead, or as an indirect expense. If you used estimated machine hours to calculate the rate, use actual machine hours. If you used direct labor hours to calculate the rate, use actual direct labor hours.
