For product B, two labor hours are needed per unit, so the overhead per unit equals two times $48, or $96. 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.
- Product A requires 1.5 hours per unit, so the overhead rate is 1.5 times $48, or $72 per unit.
- As a result, management would likely view labor hours as the activity base when applying overhead costs.
- Based on the manufacturing process, it is also easy to determine the direct labor cost.
- Some products are cheaper to ship than others, but total your shipping costs on a plant-wide basis.
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. The plantwide overhead rate is a single overhead rate that a company uses to allocate all of its manufacturing overhead costs to products or cost objects. This is a simplified approach to cost allocation that works well in smaller and simpler businesses.
Estimated Total Manufacturing Overhead Costs
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. A single overhead rate for assigning all of the manufacturing production and service department costs to products.
- A single overhead rate for assigning all of the manufacturing production and service department costs to products.
- The production hasn’t taken place and is completely based on forecasts or previous accounting records, and the actual overheads incurred could turn out to be way different than the estimate.

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. If your company manufactures several products at different locations in your plant, each product has its own overhead expenses. 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. Enter the total manufacturing overhead cost and the estimated units of the allocation base for the period to determine the overhead rate.
Predetermined Overhead Rate Formula
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. 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.

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.
The concept of predetermined overhead rate is very important because it is used most of the enterprises as it enables them to estimate the approximate total cost of each job. 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. Another approach to calculating a single or plantwide overhead rate uses direct cost as a basis, rather than direct labor hours. To find your overhead cost, add up all your subtotals of expenses, direct and indirect. Divide your total expenses for the plant by the total number of units you produce.
Advantages & Disadvantages of Using Absorption Vs. Variable Costing
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 a complete guide to california payroll taxes $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.
All of your manufacturing activities depend on the services you are paying for throughout your plant. Hence, the overhead incurred in the actual production process will differ from this estimate. Divided into the overhead of $120,000, this comes to $48 in overhead per labor hour. Product A requires 1.5 hours per unit, so the overhead rate is 1.5 times $48, or $72 per unit.
This rate is less accurate than departmental rates if a company manufactures a diverse group of products. 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. 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). Some products are cheaper to ship than others, but total your shipping costs on a plant-wide basis.

A financial professional will offer guidance based on the information provided and offer a no-obligation call to better understand your situation. Unexpected expenses can be a result of a big difference between actual and estimated overheads. Also, if the rates determined are nowhere close to being accurate, the decisions based on those rates will be inaccurate, too.
