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 costs. As mentioned in the article, accountants may use machine hours, direct labor hours or dollars, etc., as the allocation base. Suppose a business is focused on auto repair, then the accountant has to use direct labor hours in their calculation to determine how many hours it took for a mechanic to do their job. Ahead of discussing how to calculate predetermined overhead rate, let’s define it. A predetermined overhead rate(POHR) is the rate used to determine how much of the total manufacturing overhead cost will be attributed to each unit of product manufactured.
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). 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. Direct labor standard rate, machine hours standard rate, and direct labor hours standard rate are some methods of factory overhead absorption. Small companies tend to use activity-based costing, whereas in larger companies, each department in which different processes of production take place typically computes its own predetermined overhead rate. These two amounts seldom match in any accounting period, but the variance will generally average to zero after multiple quarters.
- 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.
- 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.
- The common allocation bases are direct labor hours, direct labor cost, machine hours, and direct materials.
- Also, it's important to compare the overhead rate to companies within the same industry.
For instance, if the activity base is machine hours, you calculate predetermined overhead rate by dividing the overhead costs by the estimated number of machine hours. This is calculated at the start of the accounting period and applied to production to facilitate determining a standard cost for a product. The predetermined overhead rate is set at the beginning of the year and is calculated as the estimated (budgeted) overhead costs for the year divided by the estimated (budgeted) level of activity for the year. This activity base is often direct labor hours, direct labor costs, or machine hours. Once a company determines the overhead rate, it determines the overhead rate per unit and adds the overhead per unit cost to the direct material and direct labor costs for the product to find the total cost.
Overhead Rate Formula and Calculation
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. Until now, you have learned to apply overhead to production based on a predetermined overhead rate typically using an activity base.
Companies need to make certain the sales price is higher than the prime costs and the overhead costs. In some industries, the company has no control over the costs it must pay, like tire disposal fees. To ensure that the company is profitable, an additional cost is added and the price is modified as necessary. In this example, the guarantee offered by Discount Tire does not include the disposal fee in overhead and increases that fee as necessary.
You can envision the potential problems in creating an overhead allocation rate within these circumstances. A predetermined overhead rate is calculated at the start of the accounting period by dividing the estimated manufacturing overhead by the estimated activity base. The predetermined overhead rate is then applied to production to facilitate determining a standard cost for a product. These small business banking overhead costs involve the manufacturing of a product such as facility utilities, facility maintenance, equipment, supplies, and labor costs. Whereas, the activity base used for the predetermined overhead rate calculation is usually machine hours, direct labor hours, or direct labor costs. Further, the company uses direct labor hours to assign manufacturing overhead costs to products.

If an actual rate is computed monthly or quarterly, seasonal factors in overhead costs or in the activity base can produce fluctuations in the overhead rate. For example, the costs of heating and cooling a factory in Illinois will be highest in the winter and summer months and lowest in the spring and fall. If the overhead rate is recomputed at the end of each month or each quarter based on actual costs and activity, the overhead rate would go up in the winter and summer and down in the spring and fall. As a result, two identical jobs, one completed in the winter and one completed in the spring, would be assigned different manufacturing overhead costs. To avoid such fluctuations, actual overhead rates could be computed on an annual or less-frequent basis.
How to Calculate a Predetermined Overhead Rate
Two companies, ABC company, and XYZ company are competing to get a massive order that will make them much recognized in the market. This project is going to be lucrative for both companies but after going over the terms and conditions of the bidding, it is stated that the bid would be based on the overhead rate. This means that since the project would involve more overheads, the company with the lower overhead rate shall be awarded the auction winner. Explore the latest trends in overhead rate calculation, including the impact of technology, sustainability considerations, and global economic shifts. With the aid of this rate, companies may set prices on their products or services and ensure their expenses won’t go overboard. The movie industry uses job order costing, and studios need to allocate overhead to each movie.
For example, Figure 4.18 shows the monthly costs, the annual actual cost, and the estimated overhead for Dinosaur Vinyl for the year. 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 overhead used in the allocation is an estimate due to the timing considerations already discussed. 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.
The price a business charges its customers is usually negotiated or decided based on the cost of manufacturing. This means that once a business understands the overhead costs per labor hour or product, it can then set accurate pricing that allows it to make a profit. Hence, one of the major advantages of predetermined overhead rate formula is that it is useful in price setting. For example, assume a company expects its total manufacturing costs to amount to $400,000 in 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.
Enter the total manufacturing overhead cost and the estimated units of the allocation base for the period to determine the overhead rate. There are concerns that the rate may not be accurate, as it is based on estimates rather than actual data. In addition, changes in prices and industry trends can make historical data an unreliable predictor of future overhead costs. Finally, using a predetermined overhead rate can result in inaccurate decision-making if the rate is significantly different from the actual overhead cost. Therefore, you would assign $10 to each product to account for overhead costs in your financial statements.
Benefits of Accurate Calculations
Examples of manufacturing overhead costs include indirect materials, indirect labor, manufacturing utilities, and manufacturing equipment depreciation. Another way to view it is overhead costs are those production costs that are not categorized as direct materials or direct labor. 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. Manufacturing overhead (or factory overhead) is the sum of all indirect costs incurred during the manufacturing process. You can calculate manufacturing overhead costs by adding your indirect expenses, such as direct materials and labor, into one total.
Several factors, such as the nature of the industry, technology adoption, and historical data analysis, can influence the predetermined overhead rate. 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.
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 predetermined overhead rates rather than actual overhead rates in their cost accounting systems. As you’ve learned, understanding the cost needed to manufacture a product is critical to making many management decisions (Figure 6.2).
