The overhead rate, often referred to as the standard overhead rate, is the cost that an organization allots to production in order to obtain a more accurate picture of the expenses associated with its products and services. To get the overhead rate, first, the direct and indirect costs must be added together, and then those totals must be divided by a predetermined value. Although larger manufacturing companies are required to do this as a matter of course, even smaller companies might gain something useful from assessing their overhead rate. This article will explain how to calculate a predetermined overhead rate formula.

What Is Overhead Rate?

Overhead rate is the measure of indirect cost and other allocation measures. Indirect costs are costs that are not rapidly attached to the output of a product. While allocation measures are criteria necessary to make the product or service, it could be the number of direct labor hours for a unique product or a period.

Also, the overhead rates are the costs incurred by not producing any goods at a company divided by other metrics. A company’s overhead includes all expenses on the income statement, except for those directly related to the manufacture of a product.

The overhead rate additionally represents the proportion of a company’s overhead engagement and different managerial costs to direct prices, sales, or different inputs, including system hours. It offers company owners and managers the proof of tilting costs, outstanding for instance, its direct prices of production or gross sales.

How Can You Lower Your Overhead Rate?

You can lower your overhead rate in two different ways. 

  • This is to cut administrative costs. This can be beneficial, but it can also be reversible. There’s the potential for managers to be penny-wise and pound-foolish, slashing niches unnecessarily and leading to even massive problems. 
  • The other big way to cut the overhead rate is to grow. More action spreads continuous costs. So, while costs don’t go down, the overhead rate is effectively decreasing.

How Often Should You Calculate the Overhead Rate?

It’s very essential for commercial enterprise proprietors and executives to calculate and tune overhead rates often, semiannually, or maybe quarterly. If your enterprise is developing rapidly or constantly enhancing sports or product lines, you may need to calculate even more constantly. However, assuming that your commercial enterprise isn’t enhancing instantly, though, quarterly or semiannually might now no longer be enough.

Importance of Overhead Rate 

Overhead rate is important for companies to measure and track their business. However, it is also important for them to see how their administrative costs change over time. Also, whether their company is overburdened with administrative expenses rather than profit-generating activities. This assists them in determining how much to pay for their products and determining a breakeven point when it comes to profitability.

Limitations of the Overhead Rate

When applying to companies with few overhead costs or whose costs relate to production, the expense ratio has limitations. It’s also essential to measure the predetermined overhead to other firms in the same sector. A large corporation with a main office, a benefits division, and a human capital separation will have a greater predetermined overhead than a much smaller corporation with fewer overhead expenses.

Predetermined Overhead Rate 

A predetermined overhead rate is an allocation charge that applies a certain quantity of producing overhead to task orders or products. Commonly, you can calculate a predetermined overhead rate at the start of every reporting period, which you can dictate with the aid of using a formula that divides the expected overhead charges for production and the aid of using an allocation base. The allocation base is also the interesting driver. Some normally used activity drivers are device hours, direct materials, direct labor hours, and direct hard work bucks.

Furthermore, a predetermined overhead rate is a grant speed that provides for indirect manufacturing costs that involve the production of a product. It is used to estimate future manufacturing costs. The estimate is made at the beginning of an analysis time, before the start of any projects or specific employment for which the rate is needed. Learning about the predetermined overhead rates and how you calculate it can help you use this tool for yourself.

Components of Predetermined Overhead Rate

Let’s consider the following components of the overhead rate given below:

#1. Overheads Estimation

Discovering the entire overhead identity for the goal period is the first step you need to take. The overall overheads are an aggregate of fixed, variable, and semi-variable overheads. A distinctive evaluation of beyond prices and anticipation of upcoming new prices facilitates a faulty estimation of overheads.

#2. Base Allocation

Once you estimate the whole overheads, the company wishes to become aware of the bottom unit that is in use for the allocation of overheads. The base unit may be numerous gadgets structured to measure the range of hard work hours, system hours in use, or another base depending on the kind of business. The base unit identity is important for the correct allocation; which in the end enables becoming aware of the department-sensible overall performance and troubles if any.

#3. Purpose

You need to know the predetermined amount. If you are ready to get the price sheet for a year or an extended duration, then it’s acceptable to consist of the constant price in overhead allocation. However, if you need to put up a quote for a one-time order that isn’t regular and the companies have already recovered the fixed price from the recent payment, in this case, you will keep in mind the irregular and incremental costs.

#4. Analysis

The predetermined overhead is helpful when managing the budgeted cost of each office. After the actual quantities are out, the comparison of actual and budgeted quantities helps in the labeling of variances and the characteristics that run them. This analysis is one of the most significant factors in cost accounting in any association, as it accurately specifies the reason.

#5. Accounting

This is cost accounting, which points out the important costs and minimizes them by implementing the best and new procedures. Standard cost as part of a predetermined overhead pace is normally used to specify price variance, material variance, usage variance, and various other variances needed by a company.

The Formula for Predetermined Overhead Rate

Predetermined overhead rate = Estimated manufacturing overhead cost/Estimated allocation base

The formula for the predetermined overhead rate is solely based on estimates. Therefore, the overhead incurred within the real manufacturing process will range from this estimate. You can calculate the predetermined overhead rate difference at the end of the accounting period. Commonly It is both over-absorption or under-absorption of overheads.

To further understand the formula of predetermined overhead rate, consider the following steps:

  • Find out the different overhead costs targets and also the total amount involved.
  • Specify the costs that are the same and have a relationship with the various allocation bases. 
  • Determine the allocation basis for each department, if any.
  • Divide the total overhead cost by the allocation base.
  • You can use the rate calculated in step 4 for another department. However, there is a need. for a departmental rate because of the different processes involved 

To Calculate Predetermined Overhead Rate

Let’s use the following example below to calculate the predetermined rate.

Let’s say there’s an employer ABC Ltd. which makes use of labor hours because of the base for allocation of Overheads. In the approaching year, the employer expects the overall overheads to be $150,000 and expects that there may be 3,000 direct hard work hours performed.

Formula: Predetermined Overhead Rate = Estimated Total Overhead Cost / Estimated overall gadgets withinside the allocation base

Predetermined Overhead Rate = $150,000/3,000 = $50 in keeping with direct hard work hours.

Computing the Predetermined Overhead Rate

Some issues are determining the correct predetermined overhead rate. Nevertheless, the more historical facts that a business has, the better off it is going to be while computing predetermined rates. It is likewise possible (and frequently recommended) for a business enterprise to apply specific strategies relying on the particular products, processes, and offerings inside the organization.

Managers and accounting employees have to work collectively to research the ancient overhead statistics to search for relationships between the full overhead and one of the unique allocation bases.  Therefore, the supervisor may also note that the overhead charge is typically approximately one and a half times the fee for direct exertions for a given project. If that is steady for plenty of initiatives in that branch over the last year, then the predetermined overhead rate for that branch could be computed via means of multiplying the expected fee for direct works through means by 150%.

Problems With Predetermined Overhead Rates

There are several drawbacks to using a predetermined overhead rate, which is listed below.

#1. The Overhead Rate Is Unrealistic

Because both the numerator and denominator of the calculation are estimates, the result may bear little resemblance to the actual rate.

 #2. Decisions on Sales and Production Are Flawed

If sales and production decisions are based in part on a predetermined rate, as well as the rate being inaccurate, the decisions would be incorrect as well.

 #3. Problems With Variance Recognition

The compared with the actual and predetermined overhead quantities could be charged to expenses in the current period, causing a significant change in the amount of revenue and stock assets reported.

 #4. Weak Connection to Historical Costs

The use of historical data to calculate manufacturing overhead may not be applicable if there is a sudden increase or decrease in these costs.

Uses of Predetermined Overhead Rate

Companies use predetermined overhead rates in a variety of ways, including:

#1. Finishing the Job

Businesses use this velocity to help them close their books faster by avoiding compiling actual overhead costs as part of the closing process. They will, however, have to reconcile the difference between estimated and actual overhead at the end of their fiscal year.

#2. Monitoring Relative Expenses

A predetermined overhead rate gives businesses a percentage that they can track on a quarterly, monthly, or even weekly basis. Also, the base and expense are proportionate to each other. However, you can use this to assist you in ensuring that costs do not escalate over time.

#3. Monitoring Overhead Rate

To track expenses throughout the year, a company can also, calculate actual costs on a regular basis and compare them to the predetermined overhead rate.

#4. Pricing

Once a company understands its overhead costs per product or labor hour, it can set accurate pricing that allows it to profit.

Advantages and Disadvantages of a Predetermined Overhead Rate

Let us take a look at the advantages and disadvantages of the predetermined overhead rate illustrated below.


Some of the advantages are : 

  • Enabling of brief calculation of the predicted price for every department.
  • It enables overall performance tracking.
  • Useful in making a budget ready.
  • A crucial issue of an enterprise is concerned with production activities.
  • Useful in finalizing price and promoting charge of products.


Let’s consider some of these disadvantages: 

  • It is a time-eating process.
  • Many companies discover it is hard to implement.
  • It isn’t continually easy to tune all of the destiny fees accurately.
