This allocation can come in the form of the traditional overhead allocation method or activity-based costing.. 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. 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. 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. 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.
- In contrast, the traditional allocation method commonly uses cost drivers, such as direct labor or machine hours, as the single activity.
- The predetermined overhead rate is used to price new products and to calculate variances in overhead costs.
- Your indirect costs are those that continue no matter how much or how little you manufacture.
- As you’ve learned, understanding the cost needed to manufacture a product is critical to making many management decisions (Figure 6.2).
Do not include wages for shipping personnel because you already included these in your direct costs for the entire plant. These include energy usage, wages for production and shipping personnel, and materials. Each product will use a different amount of these resources, but you can use a grand total for each direct cost as your plant-wide figure. Your indirect costs are those that continue no matter how much or how little you manufacture. These include things like rent or mortgage payments, insurance, equipment leases, and plant maintenance. This figure is your plant-wide indirect cost that you must pay just to be in business.
1 Calculate Predetermined Overhead and Total Cost under the Traditional Allocation Method
In response to this situation, manufacturers will use departmental overhead rates and perhaps activity based costing. 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.
- After reviewing the product cost and consulting with the marketing department, the sales prices were set.
- Enter the total manufacturing overhead cost and the estimated units of the allocation base for the period to determine the overhead rate.
- Per unit labor hours can be calculated by dividing the total labor hours used to manufacture each product by the number of units manufactured.

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. 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. The common allocation bases are direct labor hours, direct labor cost, machine hours, and direct materials.

Plantwide overhead rate definition
Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing. Therefore, the predetermined overhead rate of TYC Ltd for the upcoming year is expected to be $320 per hour. Small companies typically online invoicing portal use activity-based costing, while large organizations will have departments that compute their own rates. Some small products may require large quantities, while complex projects may take longer to produce and therefore result in fewer units during any given period.
How to Calculate the Overhead Rate Based on Direct Labor Cost
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. The computation of the overhead cost per unit for all of the products is shown in Figure 6.4. A predetermined overhead rate is defined as the ratio of manufacturing overhead costs to the total units of allocation.
Why You Can Trust Finance Strategists
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 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. Typically, a plantwide overhead rate assigns a cost figure based on the labor hours needed to produce one unit.

As per the budget, direct labor cost and raw material cost for the period is expected to be $40 million and $60 million respectively. The company uses machine hours to assign manufacturing overhead costs to products. 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.
Which of these is most important for your financial advisor to have?
Add up all your quality control expenses into one grand total, even if most of the quality problems are with one or two products. 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. From the above list, salaries of floor managers, factory rent, depreciation and property tax form part of manufacturing overhead.
