Hence, the overhead incurred in the actual production process will differ from this estimate. This is related to an activity rate which is a similar calculation used in Activity-based costing. A pre-determined overhead rate is normally the term when using a single, plant-wide base to calculate and apply overhead. Overhead is then applied by multiplying the pre-determined overhead rate by the actual driver units. Any difference between applied overhead and the amount of overhead actually incurred is called over- or under-applied 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.. The overhead rate is calculated by adding your indirect costs and then dividing them by a specific measurement such as machine hours, sales totals, or labor costs.
Example of predetermined overhead rate
In either case, the difference between absorbed overheads and actual overheads is adjusted in profits or losses of the business. The measures used to calculate overhead rate include machine hours or labor costs, with these costs used to determine how much indirect overhead is spent to produce products or services. Ahead of discussing how to calculate predetermined overhead rate, let’s define it.
Small companies typically use activity-based costing, while large organizations will have departments that compute their own rates. Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing. The predetermined overhead rate calculation shown in the example above is known as the single predetermined overhead rate or plant-wide overhead rate. Therefore, the predetermined overhead rate of GHJ Ltd for next year is expected to be $5,000 per machine hour.

Direct labor standard rate, machine hours standard rate, and direct labor hours standard rate are some methods of factory overhead absorption. Even small business owners will benefit from knowing what their indirect costs are and how they impact the business. Overhead costs are incurred whether the company is producing a large or small quantity of products or services. This concept is important because these costs must be estimated in order to properly provide accurate prices to future customers. If overhead is overestimated, then prices will be too high and that can cause customers to seek their products or services from other companies (most likely their competitors). If overhead is underestimated, then the company may set their prices too low and not earn profits or experience a loss.
A predetermined overhead rate, also known as a plant-wide overhead rate, is a calculation used to determine how much of the total manufacturing overhead cost will be attributed to each unit of product manufactured. The rate is determined by dividing the fixed overhead cost by the estimated number of direct labor hours. Until now, you have learned to apply overhead to production based on a predetermined overhead rate typically using an activity base. An activity base is considered to be a primary driver of overhead costs, and traditionally, direct labor hours or machine hours were used for it. For example, a production facility that is fairly labor intensive would likely determine that the more labor hours worked, the higher the overhead will be.
Predetermined Overhead Rate Basis
They can also be used to track the financial performance of a business over time. A predetermined overhead rate is an allocation rate given for indirect manufacturing costs that are involved in the production of a product (or several products). 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. The overhead cost per unit from Figure 6.4 is combined with the direct material and direct labor costs as shown in Figure 6.3 to compute the total cost per unit as shown in Figure 6.5.
The direct cost is easily allocated in the product cost as we need to allocate the quantity in line with the usage. The overhead rate is a cost added on to the direct costs of production https://turbo-tax.org/turbotax-vs-cpa/ in order to more accurately assess the profitability of each product. In more complicated cases, a combination of several cost drivers may be used to approximate overhead costs.
