Predetermined Overhead Rate

how to calculate predetermined overhead rate

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.

  • Using the plantwide allocation method, calculate the predetermined overhead rate and determine the overhead cost per unit for the inkjet and laser products.
  • The manufacturing overhead could be spread across all three accounts to be more accurate, but this is more time consuming.
  • The result of this calculation will be the predetermined overhead rate based upon the direct labor costs.
  • Another benefit of a predetermined overhead rate is for Project Planning.
  • If sales and production decisions are being made based in part on the predetermined overhead rate, and the rate is inaccurate, then so too will be the decisions.

Further, customized input from different departments can be obtained to enhance the accuracy of the budget. Most manufacturing and service organizations use predetermined rates. Since the CD requires 10 seconds of machine time, each CD will be charged for $0.30 of overhead cost.

Accounting Details

Once a company has determined the overhead, it must establish how to allocate the cost. This allocation can come in the form of the traditional overhead allocation method or activity-based costing.. The overhead rate for the molding department is computed by taking the estimated manufacturing overhead cost and dividing it by the estimated machine hours. The companies use different allocation bases when calculating their predetermined overhead rates. As mentioned above, an activity driver could be direct labor hours, machine hours or something else. If a business was an auto repair shop, then they would calculate the number of labor hours it took to complete a job. If you run a factory, you need to estimate the number of hours that a machine runs during the activity period.

  • This budget is normally prepared annually based on the related factors.
  • There could be various reasons for such variations, including seasonality.
  • The allocation base can differ depending on the nature of the costs involved.
  • Predetermined overhead is typically calculated at the beginning of each reporting period and is determined by dividing the estimated overhead costs for manufacturing by an allocation base.
  • Direct labor standard rate, machine hours standard rate, and direct labor hours standard rate are some methods of factory overhead absorption.

The predetermined overhead rate is also commonly called predetermined absorption rate or predetermined overhead absorption rate. It also can be called as predetermined manufacturing overhead rate. Before jumping to detail, let’s go through the basic overview and key definition first. Recall from Chapter 2 “How Is Job Costing Used to Track Production Costs?” that the manufacturing overhead account is closed to cost of goods sold at the end of the period.

Accounting Topics

This is the method that is used in this chapter, but it is practice that is recently come under severe criticism. A predetermined overhead rate is mainly useful in the manufacturing industry to ascertain the company’s manufacturing overhead cost.

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.

Traditionally, overheads have been absorbed in the product cost based on a single basis of apportionment. For instance, in a labor-intensive environment, labor hours were used to absorb overheads. On the other hand, the machine hours were used to absorb overheads in a machine incentive environment. You can calculate applied manufacturing overhead by multiplying the overhead allocation rate by the number of hours worked or machinery used.

So if you produce 500 units a month and spend $50 on each unit in terms of overhead costs, your manufacturing overhead would be around $25,000. This calculation will give you a basic figure for financial planning. The goal is to understand all the activities required to make the company’s products. This requires interviewing and meeting with personnel throughout the organization.

Calculate Predetermined Overhead Rate

It’s important to note that if the business uses the ABC system, the individual activity is absorbed on a specific basis. For instance, cleaning and maintenance expenses will be absorbed on the basis of the square feet as shown in the table above. Suppose following are the details regarding indirect expenses of the business. If the absorbed cost is more than the actual cost, an adjusting entry is passed to reduce the expenses. On the other hand, if the actual cost is more, an adjusting entry is passed to record the remaining cost in the business’s income statement. These costs must be included in the stock valuation of finished goods and work in progress. Both COGS and the inventory value must be reported on the income statement and the balance sheet.

Next, calculate the predetermined overhead rate for the three companies above. Therefore, the predetermined overhead rate of GHJ Ltd for next year is expected to be $5,000 per machine hour. When a company understands the overhead costs per product or labor hour, it can then set accurate pricing that allows it to earn a profit.

This charge is constant and would not be affected by the level of activity during a period. Many accountants always ask about specific time which we need to do this, at what point in time is the predetermined overhead rate calculated. The predetermined rate usually be calculated at the beginning of the accounting period by relying on the management experience and prior year data. Cost accountants want to be able to estimate and allocate overhead costs like rent, utilities, and property taxes to the production processes that use these expensesindirectly. Since they can’t just arbitrarily calculate these costs, they must use a rate.

The rate is based on one of the direct costs such as labor or machine hours, depending on the manufacturing process used. Overheads are apportioned over the total quantity of products manufactured by applying the predetermined rate to each unit produced. Predetermined overhead rate is a rate calculated in advance of the period in which it is to be used, by dividing the estimated period overhead to be absorbed by the estimated period production. Production may be measured on any of the absorption bases, such as prime cost, labour hours, etc. The costs of a product are easy to determine once the product has been produced. These costs generally include material costs, labor costs and overheads.

What Are The Limitations Of Predetermined Overhead Rates?

It is better to have a good estimate of costs when doing the work instead of waiting a long time for only a slightly more accurate number. The predetermined overhead rate for machine hours is calculated by dividing the estimated manufacturing overhead cost total by the estimated number of machine hours. This formula refers to the predetermined overhead because this overhead total is based on estimations, rather than the actual cost. The estimated or budgeted overhead is the amount of overhead determined during the budgeting process and consists of manufacturing costs but, as you have learned, excludes direct materials and direct labor. Examples of manufacturing overhead costs include indirect materials, indirect labor, manufacturing utilities, and manufacturing equipment depreciation.

A predetermined overhead rate is an allocation rate that is used to apply the estimated cost of manufacturing overhead to cost objects for a specific reporting period. This rate is frequently used to assist in closing the books more quickly, since it avoids the compilation of actual manufacturing overhead costs as part of the period-end closing process.


Dorothy’s Hat Company computed a predetermined overhead rate based on annual machine hours. A company can calculate actual costs on a periodic basis and then compare that to the predetermined overhead rate to monitor expenses throughout the year. If you work in manufacturing, establishing and monitoring an overhead rate for your business can help you keep expenses in proportion with production volumes and sales. It can help you know when you need to review your spending more closely in order to protect the company’s profit margins. Learning about predetermined overhead rate and how you calculate it can help you use this tool for yourself. When the absorption is based on actual overhead, it is known as actual absorption rate. This can be calculated only after the end -of the accounting period when all cost and production figures have been collected.

  • Conversely, if the actual manufacturing overhead was $100,000 but their applied manufacturing overhead was $120,000, they overapplied by $20,000.
  • This record maintenance and cost monitoring is expected to increase the administrative cost.
  • The gas dispensing pool included costs for storage tanks, all of which were the same size, as well as gas pumps and signs.
  • The predetermined overhead rate is found by taking the total estimated overhead costs and dividing by the estimated activity base.
  • Once the ABC information was presented, the case was settled, and the initial injunction was lifted.
  • The more consistency there is between the total overhead and the allocation base, the more accurate the estimate of predetermined overhead will be.
  • Whereas the packaging department bases its overhead rate on labor hours.

At the beginning of year 2021, the company estimated that its total manufacturing overhead cost would be $268,000 and the total direct labor cost would be 40,000 hours. The actual total manufacturing overhead incurred for the year was $247,800 and actual direct labor hours worked during the year were 42,000. 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.

How To Calculate The Overhead Budget Using The Rate

With the manufacturing overhead costs and the machine hour totals, you can calculate the predetermined overhead rate by dividing the overhead costs by the machine hours. For instance, if the manufacturer estimates $10,000 in overhead costs with 20,000 machine hours, the predetermined overhead rate is 50 cents per unit. The predetermined overhead rate was found by dividing the estimated manufacturing overhead cost by the estimated total units in the allocation base, so the predetermined overhead cost per unit is $9.00. The predetermined overhead rate formula is calculated by dividing the estimated manufacturing overhead cost by the allocation base. Predetermined overhead rate is calculated by dividing the manufacturing overhead cost by the activity driver. For example, if the activity driver was machine-hours, then you would divide overhead costs by the estimated number of machine-hours.

Based on this calculation, the business can make several decisions such as what the price of the product should be, how much resources should be allocated towards the production of the product, etc. Both of these expenses are also examples of the types of expenses that compose manufacturing overhead. An example of the current revenue recognition principle is a company paying $4,800 a year for property insurance.

Manufacturing overhead is also known as factory overheads or manufacturing support costs. Overhead costs such as general administrative expenses and marketing costs predetermined overhead rate are not included in manufacturing overhead costs. Since the predetermined overhead rate is $0.02 per second, the overhead cost applied to each CD would be $0.20.

The following estimates are provided for the coming year for the company and for the Patterson High School Science Olympiad Jacket job. The company actually had $300,000 in total manufacturing overhead costs for the year, and the actual machine hours used were 53,000. A predetermined overhead rate is an allocation rate that is used to apply an estimated cost of manufacturing overhead to either products or job orders. This step requires adding indirect materials, indirect labor, and all other product costs not included in direct materials and direct labor. Here, overhead is estimated to include indirect materials ($50 worth of coffee), indirect labor ($150 worth of maintenance), and other product costs ($200 worth of rent), for a total of $400. The basic purpose of overhead absorption rates is to absorb total overhead in products or jobs manufactured.

Fixed overheads are expected to increase/decrease per unit in line with the seasonal variations. So, the cost of a product in one period may not reflect the cost in another period—for instance, the cost of freezing fish increases in the summer and lowers in the winter.

Predetermined Overhead Rate Definition

Unexpected expenses can be a result of a big difference between actual and estimated overheads. Profits will be affected and assets may need to be worked beyond their capacity too. Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing. This means that the overhead that is applied to jobs or products is different than the actual overhead from the product or job. Company X and Company Y are competing to acquire a massive order as that will make them much recognized in the market, and also, the project is lucrative for both of them. After going to its terms and conditions of the bidding, it stated the bid would be based on the overhead rate percentage.
