As you have learned, the overhead needs to be allocated to the manufactured product in a systematic and rational manner. This allocation process depends on the use of a cost driver, which drives the production activity’s cost. Examples can include labor hours incurred, labor costs paid, amounts of materials used in production, units produced, or any other activity that has a cause-and-effect relationship with incurred costs. 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). This allocation method is similar to Direct Labor Hours, except it uses the total number of hours production machinery is in use, rather than direct labor hours of all kinds. Once you’ve identified and calculated your total indirect expenses, it’s time to choose an overhead allocation method so you can properly contextualize the results and make the right strategic decisions.

One of the advantages of predetermined overhead rate is that it can help businesses monitor overhead rate. A business can calculate its actual costs periodically and then compare that to the predetermined overhead rate in order to monitor expenses throughout the year or see how on-target their original estimate was. This comparison can be used to monitor or predict expenses for the next project (or fiscal year). Take, for instance, a manufacturing company that produces gadgets; the production process of the gadgets would require raw material inputs and direct labor. These two factors would definitely make up part of the cost of producing each gadget. Nonetheless, ignoring overhead costs, like utilities, rent, and administrative expenses that indirectly contribute to the production process of these gadgets, would result in underestimating the cost of each gadget.

If the predetermined overhead rate calculated is nowhere close to being accurate, the decisions based on this rate will definitely be inaccurate, too. That is, if the predetermined overhead rate turns out to be inaccurate and the sales and production decisions are made based on this rate, then the decisions will be faulty. When there is a big difference between the actual and estimated overheads, unexpected expenses will definitely be incurred. Also, profits will be affected when sales and production decisions are based on an inaccurate overhead rate.
Examples of Overhead Rates
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. A company’s manufacturing overhead costs are all costs other than direct material, direct labor, or selling and administrative costs.

- So, the cost of a product in one period may not reflect the cost in another period—for instance, the cost of freezing fish increases in the summer and lowers in the winter.
- A manufacturer producing a variety of products that require different processes will have multiple overhead rates known as departmental overhead rates instead of just one plant-wide overhead rate.
- This rate is useful from the point of view of cost control as it enables management to plan ahead and budget for the future.
- 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.
- For example, Figure 4.18 shows the monthly costs, the annual actual cost, and the estimated overhead for Dinosaur Vinyl for the year.
To avoid such fluctuations, actual overhead rates could be computed on an annual or less-frequent basis. However, if the overhead rate is computed annually based on the actual costs and activity for the year, the manufacturing overhead assigned to any particular job would not be known until the end of the year. For example, the cost of Job 2B47 at Yost Precision Machining would not be known until the end of the year, even though the job will be completed and shipped to the customer in March. For these reasons, most companies use a single predetermined overhead rate is called a(n)s rather than actual overhead rates in their cost accounting systems.

That means it represents an estimate of the costs of producing a product or carrying out a job. The estimate will be made at the beginning of an accounting period, before any work has actually taken place. The overhead rate is a cost allocated to the production of a product or service. Overhead costs are expenses that are not directly tied to production such as the cost of the corporate office. To allocate overhead costs, an overhead rate is applied to the direct costs tied to production by spreading or allocating the overhead costs based on specific measures. Hence, the overhead incurred in the actual production process will differ from this estimate.
- For instance, imagine that your company has a new job coming up, and you need to calculate predetermined overhead rate for an estimate of manufacturing costs.
- It is absolutely an invaluable tool for businesses of all types and sizes, but the values reached using the predetermined overhead rate calculation formula come with a bit of their own risk.
- When the $700,000 of overhead applied is divided by the estimated production of 140,000 units of the Solo product, the estimated overhead per product for the Solo product is $5.00 per unit.
- Overhead is then applied by multiplying the pre-determined overhead rate by the actual driver units.
- Using the Solo product as an example, 150,000 units are sold at a price of $20 per unit resulting in sales of $3,000,000.
