predetermined overhead rate formula

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.

predetermined overhead rate formula

That is, a predetermined overhead rate includes the ratio of the estimated overhead costs for the year to the estimated level of activity for the year. Since the rate is based solely on estimates and not confirmed costs, the end results may not always match the actual manufacturing overhead rates. Manufacturing decisions may be influenced by what the predetermined overhead rate, rather than the true production, needs.

Example of predetermined overhead rate

Further, the company uses direct labor hours to assign manufacturing overhead costs to products. As per the budget, the company will require 150,000 direct labor hours during the forthcoming year. Based on the given information, calculate the predetermined overhead rate of TYC Ltd. Overhead costs are those expenses that cannot be directly attached to a specific product, service, or process. Allocation bases (such as direct labor, direct materials, machine hours, etc.) are used when finding a relationship with total overhead costs. To calculate the predetermined overhead, the company would determine what the allocation base is.

By having multiple rates like this, you can achieve a greater degree of accuracy. The downside is that it increases the amount of accounting labor and is therefore more expensive. Whether it is products or services, companies must calculate the cost of their items. Once they can do so reliably, companies can use the information in various decisions. At the start of 2021, Dorothy’s Hat Company estimated that the total manufacturing overhead cost for the year would be $320,000, and the total machine hours would be 50,000 hours. The formula for a predetermined overhead rate is expressed as a ratio of the estimated amount of manufacturing overhead to be incurred in a period to the estimated activity base for the period.

Predetermined Overhead Rate Usage

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. The predetermined overhead rate formula is calculated by dividing the estimated manufacturing overhead cost by the allocation base. For example, the total direct labor hours estimated for the solo product is 350,000 direct labor hours. With $2.00 of overhead per direct hour, the Solo product is estimated to have $700,000 of overhead applied. 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.

predetermined overhead rate formula

It uses the total estimated overhead costs for a period and divides them by the expected production units. Consequently, it provides rates companies can apply to every product or service produced. The predetermined rate is crucial in assigning total costs to products during the manufacturing process.

Common activity bases used in the calculation include direct labor costs, direct labor hours, or machine hours. Commonly used allocation bases are direct labor hours, direct labor dollars, machine hours, and direct materials cost incurred by the process. As a result, the overhead Small Business Bookkeeping Services 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.
