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. In these situations, a direct cost (labor) has been replaced by an overhead cost (e.g., depreciation on equipment).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.
- As per the budget, the company will require 150,000 direct labor hours during the forthcoming year.
- In addition, changes in prices and industry trends can make historical data an unreliable predictor of future overhead costs.
- The predetermined overhead rate is then applied to production to facilitate determining a standard cost for a product.
- To calculate a predetermined overhead rate, divide the manufacturing overhead cost by the units of allocation.
- The predetermined overhead rate is used to price new products and to calculate variances in overhead costs.
It is an integral part of the process of cost accounting, which helps companies determine the cost of their products and services accurately. 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.

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. 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. XYZ Inc. estimates that its total manufacturing overhead costs for the upcoming year will be $500,000.
In other words, it is the total amount of factory overhead costs divided by the total amount of the allocation base. 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. Calculate the predetermined overhead rate of GHJ Ltd if the required machine hours for next year’s production is estimated to be 10,000 hours. As you’ve learned, understanding the cost needed to manufacture a product is critical to making many management decisions (Figure 6.2).
How Do You Calculate Single Plantwide Factory Overhead Rate?
However, it has limitations, such as inaccurate product costs, which can result in mispricing and lost profits. Therefore, companies should consider more sophisticated methods of allocating overhead costs, such as activity-based costing, for more accurate and reliable cost information. 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). 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. Until now, you have learned to apply overhead to production based on a predetermined overhead rate typically using an activity base. 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.
Hence, the overhead incurred in the actual production process will differ from this estimate. Using a plantwide overhead rate is simpler than other allocation methods, such as departmental rates or activity-based costing, but it might not be as accurate because it assumes all products or services use overhead resources in the same way. This assumption may not hold true if a company produces a variety of products with different production processes, complexities, or volumes.
Step 2 of 3
This predetermined rate was based on a cost formula that estimated $\$ 257,400$ of total manufacturing overhead cost for an estimated activity level of 11,000 direct labor-hours. The most common allocation base used in manufacturing is machine hours, direct labor hours, or direct materials cost. For example, if the allocation base is machine hours, estimate the total number of machine hours for the period. Further, the company uses direct labor hours to assign manufacturing overhead costs to products. As per the budget, the company will require 150,000 direct labor hours during the forthcoming year.

Plantwide Overhead Rate Method 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. 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 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. A predetermined overhead rate is defined as the ratio of manufacturing overhead costs to the total units of allocation. A single plantwide factory overhead rate is used to allocate overhead costs to products.
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 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. 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. In a real-world scenario, a company may have a complex mix of products with different production requirements, which might lead it to use a more sophisticated overhead allocation method, like departmental rates or activity-based costing.
The sales price, cost of each product, and resulting gross profit are shown in Figure 6.6. The monthly accounting close process for a nonprofit organization involves a series of steps to ensure accurate and up-to-date financial records. 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. Harold Averkamp (CPA, MBA) has worked as a university accounting instructor, accountant, and consultant for more than 25 years.
Based on the given information, calculate the predetermined overhead rate of TYC Ltd. Once you have determined the single plantwide factory overhead rate, you can apply it to the products manufactured in the plant. Multiply the overhead rate by the actual amount of the allocation base used for each product to allocate the overhead costs to each product. For example, if Product A requires 10 machine hours, the total overhead cost allocated to Product A would be $100 ($10 x 10).
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. The first step is to determine the total estimated manufacturing overhead costs for the period. These costs include indirect materials, indirect labor, rent, utilities, depreciation, insurance, and other indirect expenses. Luthan Company uses a plantwide predetermined overhead rate of $\$ 23.40$ per direct labor-hour.
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. Enter the total manufacturing overhead cost and the estimated units of the allocation base for the period to determine the overhead rate. For example, the total direct labor hours estimated for the solo product is 350,000 direct labor hours. With $2.00 of overhead per direct hour, the Solo product is estimated to have $700,000 of overhead applied. 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.
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. The allocation base (also known as the activity base or activity driver) can differ depending on the cash conversion cycle explained in 60 seconds nature of the costs involved. From the above list, salaries of floor managers, factory rent, depreciation and property tax form part of manufacturing overhead. Small companies typically use activity-based costing, while large organizations will have departments that compute their own rates. After reviewing the product cost and consulting with the marketing department, the sales prices were set.
