How to Calculate Predetermined Overhead Rate

The allocation base (also known as the activity base or activity driver) can differ depending on the nature of the costs involved. Therefore, the predetermined overhead rate of GHJ Ltd for next year is expected to be $5,000 per machine hour. Therefore, the predetermined overhead rate of TYC Ltd for the upcoming year is expected to be $320 per hour.

However, the use of multiple predetermined overhead rates also increases the amount of required accounting labor. If you want to measure your indirect costs against direct labor, you would take your indirect cost total and divide it by your direct labor cost. The equation for the overhead rate is overhead (or indirect) costs divided by direct costs or whatever you’re measuring. Direct costs typically are direct labor, direct machine costs, or direct material costs—all expressed in dollar amounts. Each one of these is also known as an “activity driver” or “allocation measure.”

Which of these is most important for your financial advisor to have?

Before calculating the overhead rate, you first need to identify which allocation measure to use. An allocation measure is something that you use to measure your total overall costs. Therefore, this predetermined overhead rate of 250 is used in the pricing of the new product. 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.

• Hence, it is essential to use rates that determine how much of the overhead costs are applied to each unit of production output.
• Job costing is possible only in businesses where the production is done as per the customer’s requirement.
• This is calculated at the start of the accounting period and applied to production to facilitate determining a standard cost for a product.
• Finally, you would divide the indirect costs by the allocation measure to achieve how much in overhead costs for every dollar spent on direct labor for the week.

Hence, the overhead incurred in the actual production process will differ from this estimate. 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). A number of possible allocation bases predetermined overhead rate formula are available for the denominator, such as direct labor hours, direct labor dollars, and machine hours. On your current project (coded as J-17), your division has spent $2,600 on direct materials; therefore, the predetermined overhead for this project will be $4,550 ($2,600 × 175%).

Examples of Predetermined Overhead Rate

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 https://www.bookstime.com/ costs. The predetermined overhead rate formula can be used to balance expenses with production costs and sales. For businesses in manufacturing, establishing and monitoring an overhead rate can help keep expenses proportional to production volumes and sales.

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. The predetermined overhead rate is used to price new products and to calculate variances in overhead costs.

What information do you need to calculate predetermined overhead rate?

This chapter will explain the transition to ABC and provide a foundation in its mechanics. The use of such a rate enables an enterprise to determine the approximate total cost of each job when completed. In recent years increased automation in manufacturing operations has resulted in a trend towards machine hours as the activity base in the calculation. The difference between the actual and predetermined amounts of overhead could be charged to expense in the current period, which may create a material change in the amount of profit and inventory asset reported.

Big businesses may actually use different predetermined overhead rates in different production departments, as these may vary significantly. 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.
