If sales and production decisions are being made based in part on the predetermined overhead rate, and the rate is inaccurate, then so too will be the decisions. Now, let’s look at some hypothetical business models to see actual use-cases for predetermined overhead rates. That’s the entire idea of predetermined overhead rates—by estimating the amount of overhead that will be incurred, you can better plan for and control these costs. These costs cannot be easily traced back to specific products or services and are typically fixed in nature. The allocation of overhead to the cost of the product is also recognized in a systematic and rational manner. The overhead is then applied to the cost of the product from the manufacturing overhead account.
- 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.
- With $2.00 of overhead per direct hour, the Solo product is estimated to have $700,000 of overhead applied.
- Businesses monitor relative expenses by having an idea of the amount of base and expense that is being proportionate to each other.
- In recent years increased automation in manufacturing operations has resulted in a trend towards machine hours as the activity base in the calculation.
- Allocation bases are known amounts that are measured when completing a process, such as labor hours, materials used, machine hours, or energy use.
Unexpected expenses can be a result of a big difference between actual and estimated overheads. While this is a necessity for larger manufacturing businesses, even small businesses can benefit from calculating their overhead rate. Let’s say we want to calculate the overhead cost of a homemade candle eCommerce business. 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.
What are some examples of overhead costs?
Allocation bases (such as direct labor, direct materials, machine hours, etc.) are used when finding a relationship with total overhead costs. Management analyzes the costs and selects the activity as the estimated activity base because it drives the overhead costs of the unit. For example, assume a company expects its total manufacturing costs to amount to $400,000 in that limit activity the coming period and the company expects the staff to work a total of 20,000 direct labor hours. In order to calculate the predetermined overhead rate for the coming period, the total manufacturing costs of $400,000 is divided by the estimated 20,000 direct labor hours. To calculate the predetermined overhead, the company would determine what the allocation base is.
The third step is to compute the predetermined overhead rate by dividing the estimated total manufacturing overhead costs by the estimated total amount of cost driver or activity base. Common activity bases used in the calculation include direct labor costs, direct labor hours, or machine hours. As a result, the overhead costs that will be incurred in the actual production process will differ from this estimate. The activity base (also known as the allocation base or activity driver) in the formula for predetermined overhead rate is often direct labor costs, direct labor hours, or machine hours. That is, a number of possible allocation bases such as direct labor hours, direct labor dollars, or machine hours can be used for the denominator of the predetermined overhead rate equation. The predetermined overhead rate is calculated by dividing the estimated manufacturing overhead by the estimated activity base (direct labor hours, direct labor dollars, or machine hours).
1 Calculate Predetermined Overhead and Total Cost under the Traditional Allocation Method
For example, if ABC Manufacturing’s actual manufacturing overhead was $100,000 but their applied manufacturing overhead was only $60,000, they underapplied $40,000. Conversely, if the actual manufacturing overhead was $100,000 but their applied manufacturing overhead was $120,000, they overapplied by $20,000. If a factory is producing some goods, the accountant should determine the number of hours a machine uses during the activity period.

To conclude, the predetermined rate is helpful for making decisions, but other factors should be taken into consideration, too.

Direct costs typically are direct labor, direct machine costs, or direct material costs—all expressed in dollar amounts. Predetermined overhead rates are essential to understand for eCommerce businesses as they can be used to price products or services more accurately. They can also be used to track the financial performance of a business over time. In order to find the overhead rate we will use the same basis that we have chosen by multiplying this basis by the calculated rate. For example, if we choose the labor hours to be the basis then we will multiply the rate by the direct labor hours in each task during the manufacturing process. As mentioned in the article, accountants may use machine hours, direct labor hours or dollars, etc., as the allocation base.
However, the use of multiple predetermined overhead rates also increases the amount of required accounting labor. This means that for every dollar of direct labor costs, the business will incur $0.20 in overhead costs. When you determine all company’s manufacturing overhead costs, add them to get the total.
How to calculate a predetermined overhead rate
A good rule of thumb is to ask yourself if the cost will be incurred regardless of how much product you’re making. But before we dive deeper into calculating predetermined overhead, we need to understand the concept of overhead itself.

Examples of overhead rate measures
The overhead used in the allocation is an estimate due to the timing considerations already discussed. Direct labor standard rate, machine hours standard rate, and direct labor hours standard rate are some methods of factory overhead absorption. The most prominent concern of this rate is that it is not realistic being that it is based on estimates. Since the numerator and denominator of the POHR formula are comprised of estimates, there is a possibility that the result will not be close to the actual overhead rate. The fact is production has not taken place and is completely based on previous accounting records or forecasts.
This means that for every hour of work the marketing agency performs, it will incur $20 in overhead costs. With the aid of this rate, companies may set prices on their products or services https://www.wave-accounting.net/ and ensure their expenses won’t go overboard. Also, if the rates determined are nowhere close to being accurate, the decisions based on those rates will be inaccurate, too.
Departmental overhead rates are needed because different processes are involved in production that take place in different departments. 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. 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. This predetermined overhead rate can also be used to help the marketing agency estimate its margin on a project. This predetermined overhead rate can be used to help the marketing agency price its services.
Overhead rate is a percentage used to calculate an estimate for overhead costs on projects that have not yet started. It involves taking a cost that is known (such as the cost of materials) and then applying a percentage (the predetermined overhead rate) to it in order to estimate a cost that is not known (the overhead amount). The predetermined overhead rate can be either overapplied or underapplied, depending on how accurate the company estimated the manufacturing overhead. The manufacturing overhead could be spread across all three accounts to be more accurate, but this is more time consuming. The limitations and problems of the predetermined overhead rate are that they are not always realistic, accurate decision-making can be affected, and historical costs do not always match current costs.
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.
