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).
- A predetermined overhead rate is calculated at the start of the accounting period by dividing the estimated manufacturing overhead by the estimated 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.
- How to calculate plantwide predetermined overhead rate, The formula for the predetermined overhead rate is purely based on estimates.
- The articles and research support materials available on this site are educational and are not intended to be investment or tax advice.
- 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.
- However, in recent years the manufacturing operations have started to use machine hours more predominantly as the allocation base.
Overhead costs are then allocated to production according to the use of that activity, such as the number of machine setups needed. In contrast, the traditional allocation method commonly uses cost drivers, such as direct labor or machine hours, as the single activity. How to calculate plantwide predetermined overhead rate, The formula for the predetermined overhead rate is purely based on estimates.
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).
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 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.
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.
The single plantwide factory overhead rate is called a “plantwide” rate because it applies the same overhead rate to all products manufactured in the same plant. This method of allocation is simple and easy to use, making it popular among small businesses with homogeneous product lines. 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. The predetermined overhead rate is used to price new products and to calculate variances in overhead costs.
The computation of the overhead cost per unit for all of the products is shown in Figure 6.4. 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 company incurred actual total manufacturing overhead cost of $\$ 249,000$ and 10,800 total direct labor-hours during the period.
They also estimate that they will have a total of 10,000 direct labor hours for the same period. A plantwide overhead rate is a single predetermined overhead rate that a company uses to allocate all of its manufacturing overhead costs to its products or services. It’s called “plantwide” because it applies to the entire plant’s production activities rather than specific departments or activities. Calculating the single plantwide factory overhead rate is an important step in allocating overhead costs to products. This method of allocation is easy to use and is suitable for small businesses with homogeneous product lines.
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.
- 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.
- Based on the manufacturing process, it is also easy to determine the direct labor cost.
- However, it has limitations, such as inaccurate product costs, which can result in mispricing and lost profits.
- 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.
- 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 estimated total overhead costs are then divided by the estimated total of the allocation base. A single plantwide factory overhead rate is a predetermined overhead rate used to allocate manufacturing overhead costs to products. The rate is calculated by dividing the total estimated manufacturing overhead costs by the estimated total amount of the allocation base (i.e., the activity level).

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 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.

Which of the following is the formula to calculate the predetermined factory overhead rate?
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.

All such information is provided solely for convenience purposes only and all users thereof should be guided accordingly. 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.
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. Its direct materials consist of hardware and software that it purchases and installs on behalf of its clients. Direct labor standard rate, machine hours standard rate, and direct labor hours standard rate are some methods of factory overhead absorption. 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, 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.
