Predetermined overhead rate definition

the predetermined overhead rate is based on total costs and activity base.

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. 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.

For Yore Company, dividing total fixed manufacturing overhead by units produced gave a bit of a skewed number according to the production manager because deluxe purses take twice as much effort to produce as a basic purse. Overhead costs are allocated to products by multiplying the predetermined overhead rate for each activity (calculated in step 4) by the level of cost driver activity used by the product. Once the total overheads are estimated, the organization needs to identify the base unit used for allocating overheads. The base unit can be the number of units produced; labor hours worked, machine hours utilized, or any other base depending on the type of business.

Predetermined Overhead Rate Formula

And assigning costs to products requires a significant amount of time in the accounting department. Imagine having 15 cost pools (activities), each with a predetermined overhead rate used to assign overhead costs to the company’s 80 products—not an unrealistic example for a large company. The application rate that will be used in a coming period, such as the next year, is often estimated months before the actual overhead costs are experienced.

  • 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.
  • 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.
  • Knowing the total and component costs of the product is necessary for price setting and for measuring the efficiency and effectiveness of the organization.
  • The point here is that managers must beware of using per unit cost information blindly for decision making, particularly if a significant change in the level of production is anticipated.
  • The sum of all the activity costs is the amount of factory overhead applied to the job.
  • For example, if we choose the labor hours to be the basis then we will multiply the rate by the direct labor hours in each task during the manufacturing process.

By using an estimated rate, the company can allocate costs fairly and accurately, and can use this information to make informed decisions about pricing and production processes. The computation of the overhead cost per unit for all of the products is shown in Figure 6.2.3. The management of Parker Company would like to use activity-based costing to allocate overhead rather than use one plantwide rate based on direct labor hours. The following estimates are for the activities and related cost drivers identified as having the greatest impact on overhead costs. This is the same cost figure used for the plantwide and department allocation methods we discussed earlier. Activity-based costing simply provides a more refined way to allocate the same overhead costs to products.

Example of Predetermined Overhead Rate

Overhead is then applied by multiplying the pre-determined overhead rate by the actual driver units. Any difference between applied overhead and the amount of overhead actually incurred is called over- or under-applied overhead. The allocation of overhead to the cost of the product is also recognized in a systematic and rational manner.

  • As you have learned, the overhead needs to be allocated to the manufactured product in a systematic and rational manner.
  • A cost object (in the case of manufacturing, the item produced) is the target of the activity.
  • The person involved in preparing and finalizing overhead rates must have an eye for detail and an in-depth understanding of products and the manufacturing process within the organization.
  • 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 first two cost pools allocated costs using gallons of gas sold and therefore were allocated as they would be with the plantwide approach (63 percent for regular grade, 20 percent for plus, and 17 percent for premium).
  • Estimating overhead costs is difficult because many costs fluctuate significantly from when the overhead allocation rate is established to when its actual application occurs during the production process.

It is unlikely that one rate can capture all the diversity of what goes on in a factory with reliable precision. Both costing experts had to allocate costs to each of the three grades of gasoline (regular, plus, and premium) to determine a total cost per grade of fuel and a cost per gallon for each grade. Sales of regular grade fuel were significantly higher (63 percent of total sales) than the other two grades. Using the plantwide approach, the plaintiff‘s expert allocated all costs based on gallons of gas sold. Using the activity-based costing approach, the defendant‘s expert formed three activity cost pools—labor, kiosk, and gas dispensing.

Module 4: Allocating Manufacturing Overhead

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.

the predetermined overhead rate is based on total costs and activity base.

Therefore, the predetermined overhead rate of GHJ Ltd for next year is expected to be $5,000 per machine hour. However, the production manager wants to see if there are other, more rational ways to allocate overhead that take into account the longer and more intense production time and energy to produce the deluxe purse. Compared with the plantwide approach, activity-based costing showed a lower cost per gallon for regular gas and a higher cost per gallon for the other two grades of fuel. Once the ABC information was presented, the case was settled, and the initial injunction was lifted. Notice that this information includes an estimate of the level of activity for each cost driver, which is needed to calculate a predetermined rate for each activity in step 4.

For example, the costs of heating and cooling a factory in Illinois will be highest in the winter and summer months and lowest in the spring and fall. If the overhead rate is recomputed at the end of each month or each quarter based on actual costs and activity, the overhead rate would go up in the winter and summer and down in the spring and fall. 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.

The first step is to identify the total overheads identification for the target period. The total overheads are a combination of fixed, variable, and predetermined overhead rate semi-variable overheads. A detailed analysis of past expenses and anticipation of upcoming new expenses helps inaccurate estimation of overheads.

Companies like Chrysler Group LLC have been known to try ABC, only to meet resistance from their managers. Until managers are willing to use the ABC information to make improvements in the organization, there is no point in implementing such a system. The cost information provided by ABC is generally regarded as more accurate than the information provided by most traditional costing methods. This allows management to make better decisions in areas such as product pricing, product line changes (adding products or eliminating products), and product mix decisions (how much of each product to produce and sell). 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.
