As a result, two identical jobs, one completed in the winter and one completed in the spring, would be assigned different manufacturing overhead costs. To avoid such fluctuations, actual overhead rates could be computed on an annual or less-frequent basis. However, if the overhead rate is computed annually based on the actual costs and activity for the year, the manufacturing overhead assigned to any particular job would not be known until the end of the year. For example, the cost of Job 2B47 at Yost Precision Machining would not be known until the end of the year, even though the job will be completed and shipped to the customer in March. For these reasons, most companies use predetermined overhead rates rather than actual overhead rates in their cost accounting systems. Let us take the example of ort GHJ Ltd which has prepared the budget for next year.

Predetermined Overhead Rate Formula

• As per the budget, the company will require 150,000 direct labor hours during the forthcoming year.
• Traditionally, direct labor hours were used as the activity base, but technology continually decreases the amount of direct labor used in production, and machine hours or units produced have become more common activity bases.
• In some industries, the company has no control over the costs it must pay, like tire disposal fees.
• Overhead expenses are generally fixed costs, meaning they’re incurred whether or not a factory produces a single item or a retail store sells a single product.
• You can envision the potential problems in creating an overhead allocation rate within these circumstances.

At the end of the year, the amount of overhead estimated and applied should be close, although it is rare for the applied amount to exactly equal the actual overhead. For example, Figure 4.18 shows the monthly costs, the annual actual cost, and the estimated overhead for Dinosaur Vinyl for the year. For example, the recipe for shea butter has easily identifiable quantities of shea nuts and other ingredients.

Selecting an Estimated Activity Base

The manufacturing overhead could be spread across all three accounts to be more accurate, but this is more time consuming. The limitations and problems of the predetermined overhead rate are that they are not always realistic, accurate decision-making can be affected, and historical costs do not always match current costs. As the predetermined overhead rate is an estimate of what the company believes will be the cost for manufacturing the product, the actual costs could be different than what they estimated.

Examples of Overhead Rates

Examples of manufacturing overhead costs include indirect materials, indirect labor, manufacturing utilities, and manufacturing equipment depreciation. Another way to view it is overhead costs are those production costs that are not categorized as direct materials or direct labor. 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 several concerns with using a predetermined overhead rate, which include are noted below. Small companies typically use activity-based costing, while large organizations will have departments that compute their own rates. 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. Since POHR is purely based on estimates, this means that there might be a difference between the actual and the estimated amounts of overhead and therefore, they must be reconciled at least at the end of each financial year.

• A manufacturer producing a variety of products that require different processes will have multiple overhead rates known as departmental overhead rates instead of just one plant-wide overhead rate.
• The predetermined overhead rate, also known as the plant-wide overhead rate, is used to estimate future manufacturing costs.
• During that same month, the company logs 30,000 machine hours to produce their goods.
• As a result, two identical jobs, one completed in the winter and one completed in the spring, would be assigned different manufacturing overhead costs.
• In this case, these numbers are not estimated because they are historical figures.

The actual amount of total overhead will likely be different by some degree, but your job is to provide the best estimate for each project by using the predetermined overhead rate that you just computed. A predetermined overhead rate is often an annual rate used to assign or allocate indirect manufacturing costs to the goods it produces. Manufacturing overhead is allocated to products for various reasons including compliance with U.S. accounting principles and income tax regulations. 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.

• Since POHR is purely based on estimates, this means that there might be a difference between the actual and the estimated amounts of overhead and therefore, they must be reconciled at least at the end of each financial year.
• A company that excels at monitoring and improving its overhead rate can improve its bottom line or profitability.
• Other typical examples of overhead in cost accounting include indirect labor, indirect materials, utilities, and depreciation.

Allocation bases are known amounts that are measured when completing a process, such as labor hours, materials used, machine hours, or energy use. The more consistency there is between the total overhead and the allocation base, the more accurate the estimate of predetermined overhead will be. 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.

Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing. The movie industry uses job order costing, and studios need to allocate overhead to each movie. Their amount of allocated overhead is not publicly known because while publications share how much money a movie has produced in ticket sales, it is rare that the actual expenses are released to the public.

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. Overhead costs are those expenses that cannot be directly attached to a specific product, service, or process. Allocation bases (such as direct labor, direct materials, machine hours, etc.) are used when finding a relationship with total overhead costs. To calculate the predetermined overhead, the company would determine what the allocation base is. The allocation base could be direct labor costs, direct labor dollars, or the number of machine-hours.

How to Treat Overhead Expenses in Cost Accounting

Other typical examples of overhead in cost accounting include indirect labor, indirect materials, utilities, and depreciation. A predetermined overhead rate is defined as the ratio of manufacturing overhead costs to the total units of allocation. 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.
