Let us take the example of ort GHJ Ltd which has prepared the budget for next year. The company estimates a gross profit of $100 million on total estimated revenue of $250 million. As per the budget, direct labor cost and raw material cost for the period is expected to be $40 million and $60 million respectively.
For example, the recipe for shea butter has easily identifiable quantities of shea nuts and other ingredients. Based on the manufacturing process, it is also easy to determine the direct labor cost. But determining the exact overhead costs is not easy, as the cost of electricity needed to dry, crush, and roast the nuts changes depending on the moisture content of the nuts upon arrival. Direct labor standard rate, machine hours standard rate, and direct labor hours standard rate are some methods of factory overhead absorption.
- These include things like rent or mortgage payments, insurance, equipment leases, and plant maintenance.
- 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.
- The estimate is made at the beginning of an accounting period, before the commencement of any projects or specific jobs for which the rate is needed.
- 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.
Sales of each product have been strong, and the total gross profit for each product is shown in Figure 6.7. 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. The cost of goods sold consists of direct materials of $3.50 per unit, direct labor of $10 per unit, and manufacturing overhead of $5.00 per unit. With 150,000 units, the direct material cost is $525,000; the direct labor cost is $1,500,000; and the manufacturing overhead applied is $750,000 for a total Cost of Goods Sold of $2,775,000. Another approach to calculating a single or plantwide overhead rate uses direct cost as a basis, rather than direct labor hours. If your company manufactures several products at different locations in your plant, each product has its own overhead expenses.
Predetermined Overhead Rate: Definition
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. A company’s manufacturing overhead costs are all costs other than direct material, direct labor, or selling and administrative costs.
- The company estimates a gross profit of $100 million on total estimated revenue of $250 million.
- To calculate this number, identify the total direct cost of production and the total overhead costs for the month.
- If your company manufactures several products at different locations in your plant, each product has its own overhead expenses.
- Direct labor standard rate, machine hours standard rate, and direct labor hours standard rate are some methods of factory overhead absorption.
- A plant-wide overhead rate is often a single rate per hour or a percentage of some cost that is used to allocate or assign a company’s manufacturing overhead costs to the goods produced.
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. 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.
Component Categories under Traditional Allocation
To calculate this number, identify the total direct cost of production and the total overhead costs for the month. First, find the total of all operational costs other than the direct cost of production for the period you are measuring. You have to consider more than the cost of the goods or services your company sells when you set prices.
The predetermined overhead rate calculation shown in the example above is known as the single predetermined overhead rate or plant-wide overhead rate. Company B wants a predetermined rate for a new product that it will be launching soon. Its production department comes up with the details of how much the overheads will be and what other costs will be incurred. Departmental overhead rates are needed because different processes are involved in production that take place in different departments. However, one major disadvantage of the method is that both the numerator and the denominator are estimates and as such, it is possible that the actual result may vary significantly from the predetermined overhead rate.
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. As a result, management would likely view labor hours as the activity base when applying overhead costs.
Larger organizations employ different allocation bases for determining the predetermined overhead rate in each production department. However, in recent years the manufacturing operations have started to use machine hours more predominantly as the allocation base. To calculate the plantwide overhead rate, first divide total overhead by the number of direct labor hours used to find the overhead per labor hour. Next, multiply the overhead per labor hour by the number of labor hours used to produce each unit.

To conclude, the predetermined rate is helpful for making decisions, but other factors should be taken into consideration, too. While it may become more complex to have different rates for each department, it is still considered more accurate and helpful because the level of efficiency and precision increases.
Instead of figuring overhead costs for each product, you can calculate plant-wide expenses. This averages the costs for all products, and gives you an overview of expenses for your entire manufacturing operation. Sometimes called the “predetermined overhead rate,” your plant-wide figure helps you understand your company profitability. In response to this situation, manufacturers will use departmental overhead rates and perhaps activity based costing. To find your overhead cost, add up all your subtotals of expenses, direct and indirect.
Calculation of Predetermined Overhead and Total Cost under Traditional Allocation
Add up all your quality control expenses into one grand total, even if most of the quality problems are with one or two products. The allocation base (also known as the activity base or activity driver) can differ depending on the nature of the costs involved. The estimate is made at the beginning of an accounting period, before the commencement of any projects or specific jobs for which the rate is needed. From the above list, salaries of floor managers, factory rent, depreciation and property tax form part of manufacturing overhead.
What is a plant-wide overhead rate?
Also, if the rates determined are nowhere close to being accurate, the decisions based on those rates will be inaccurate, too.

Estimated Total Manufacturing Overhead Costs
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.

To account for these changes in technology and production, many organizations today have adopted an overhead allocation method known as activity-based costing (ABC). This chapter will explain the transition to ABC and provide a foundation in its mechanics. To calculate a predetermined overhead rate, divide the manufacturing forecasting the income statement overhead cost by the units of allocation. You also need the total number of direct labor hours and the direct labor hours required to produce each product the plant manufactures. Per unit labor hours can be calculated by dividing the total labor hours used to manufacture each product by the number of units manufactured.
Divide your total expenses for the plant by the total number of units you produce. Using the plantwide overhead rate formula, if expenses come to $10,000 for instance and you produce 2,500 units, $10,000 divided by 2,500 equals four. Enter the total manufacturing overhead cost and the estimated units of the allocation base for the period to determine the overhead rate. In these situations, a direct cost (labor) has been replaced by an overhead cost (e.g., depreciation on equipment). Because of this decrease in reliance on labor and/or changes in the types of production complexity and methods, the traditional method of overhead allocation becomes less effective in certain production environments.
