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. 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. Departmental overhead rates are needed because different processes are involved in production that take place in different departments.
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. 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.
The sales price, cost of each product, and resulting gross profit are shown in Figure 6.6. 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. From the above list, salaries of floor managers, factory rent, depreciation and property tax form part of manufacturing overhead.
- 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.
- 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.
- Departmental overhead rates are needed because different processes are involved in production that take place in different departments.
- This activity base is often direct labor hours, direct labor costs, or machine hours.
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 single overhead rate for assigning all of the manufacturing production and service department costs to products. This rate is less accurate than departmental rates if a company manufactures a diverse group of products. Direct labor standard rate, machine hours standard rate, and direct labor hours standard rate are some methods of factory overhead absorption.

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.
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. The term “predetermined overhead rate” refers to the allocation rate that is assigned to products or job orders at the beginning of a project based on the estimated cost of manufacturing overhead for a specific period of reporting.
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. 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. 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. However, if the company manufactures diverse products, some of which use expensive equipment while some use only inexpensive equipment, or the company wants precise costs for pricing decisions, a plant-wide rate is not appropriate.
Which of the following is the formula to calculate the predetermined factory overhead rate?
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. The predetermined overhead rate is used to price new products and to calculate variances in overhead costs. Regardless of the approach used to allocate overhead, a predetermined overhead rate is established for each cost pool. The plantwide allocation approach uses one cost pool to collect and apply overhead costs and therefore uses one predetermined overhead rate for the entire company. Its direct materials consist of hardware and software that it purchases and installs on behalf of its clients.
What is your current financial priority?
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. For example, the total direct labor hours estimated for the solo product is 350,000 direct labor hours.
Predetermined Overhead Rate: Explanation
The common allocation bases are direct labor hours, direct labor cost, machine hours, and direct materials. How to calculate plantwide predetermined overhead rate, The formula for the predetermined overhead rate is purely based on estimates. Hence, the overhead incurred in the actual production process will differ from this estimate. It has been suggested that the problem lies with manufacturing overhead because it is the largest element of total manufacturing cost. Accordingly, you have been asked to find a more appropriate way of assigning manufacturing overhead cost to units of product.
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.

To conclude, the predetermined rate is helpful for making decisions, but other factors should be taken into consideration, too.
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.
A company’s manufacturing overhead costs are all costs other than direct material, direct labor, or selling and administrative costs. Once a company has determined the overhead, it must establish how to allocate the cost. This allocation can come in the form of the traditional overhead allocation method or activity-based costing.. 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.
