A predetermined overhead rate (pohr) is use to calculate the amount of manufacturing overhead which is to be applied to the cost of a product. The most prominent concern of this rate is that it is not realistic being that it is based on estimates. Since the numerator and denominator of the POHR formula are comprised of estimates, there is a possibility that the result will not be close to the actual overhead rate. The fact is production has not taken place and is completely based on previous accounting records or forecasts.
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. Ahead of discussing how to calculate predetermined overhead rate, let’s define it. A predetermined overhead rate(POHR) is the rate used to determine how much of the total manufacturing overhead cost will be attributed to each unit of product manufactured. If the business uses machine hours as the activity base and the estimated machine hours for the year is 5,000 then the machine hour rate calculation formula can be used as follows to calculate the predetermined overhead rate.
Also, if the rates determined are nowhere close to being accurate, the decisions based on those rates will be inaccurate, too. The predetermined overhead rate calculation shown in the example above is known as the single predetermined overhead rate or plant-wide overhead rate. The overhead will be allocated to the product units at the rate of 10.00 for each machine hour used. These estimates were made last year and will be used during all of the current year. In practice, companies most frequently set rates for the entire year, although some set rates for shorter periods, such as a quarter. 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.
- Examples can include labor hours incurred, labor costs paid, amounts of materials used in production, units produced, or any other activity that has a cause-and-effect relationship with incurred costs.
- Imagine that each month you produce 100,000 gallons of vanilla ice cream and your friend produces 100,000 gallons of 39 different flavors of ice cream.
- The predetermined overhead rate calculation shown in the example above is known as the single predetermined overhead rate or plant-wide overhead rate.

Based on the above information, we must calculate the predetermined overhead rate for both companies to determine which company has more chance of winning the auction. In the table below, we present several examples of the cost drivers companies use. Most cost drivers are related to either the volume of production or to the complexity of the production or marketing process.
Company B wants a predetermined rate for a new product that it will be launching soon. Its production department comes up with the details of how much the overheads will be and what other costs will be incurred. This video will discuss the differences between the traditional costing method and activity based costing. Since both the numerator and denominator of the calculation are comprised of estimates, it is possible that the result will not bear much resemblance to the actual overhead rate. To keep this from being an issue, base the estimates on recent actual history, adjusted for your best estimate of production activity in the near future.
Whereas, the activity base used for the predetermined overhead rate calculation is usually machine hours, direct labor hours, or direct labor costs. 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.
Why You Can Trust Finance Strategists
Establishing the overhead allocation rate first requires management to identify which expenses they consider manufacturing overhead and then to estimate the manufacturing overhead for the next year. Manufacturing overhead costs include all manufacturing costs https://www.wave-accounting.net/ except for direct materials and direct labor. 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.
Two companies, ABC company, and XYZ company are competing to get a massive order that will make them much recognized in the market. This project is going to be lucrative for both companies but after going over the terms and conditions of the bidding, it is stated that the bid would be based on the overhead rate. This means that since the project would involve more overheads, the company with the lower overhead rate shall be awarded the auction winner. To conclude, the predetermined rate is helpful for making decisions, but other factors should be taken into consideration, too. From the above list, salaries of floor managers, factory rent, depreciation and property tax form part of manufacturing overhead. Notice how the total overhead for the month of January is the same at $200,000 but the amount allocated to each product is different.
How to calculate the predetermined overhead rate
If the job in work in process has recorded actual material costs of 4,640 for the accounting period then the predetermined overhead applied to the job is calculated as follows. A predetermined overhead rate is calculated before the start of an accounting period. Depending on the size of the business the predetermined overhead rate might be calculated for the whole business or, for a larger business, separate rates might be calculated for each department using a suitable basis. The allocation of overhead to the cost of the product is also recognized in a systematic and rational manner. The overhead is then applied to the cost of the product from the manufacturing overhead account.
If at the beginning of the year the business estimates that manufacturing overheads will be 50,000 and that the estimated activity level will be 40,000 labor hours, then the pre-determined overhead rate is calculated as follows. Look at the overhead rates computed for the four activities in the table below. Note that the total overhead for current year is $2,000,000 using activity-based costing, just as it was using a traditional costing method. The total amount the structure of the saxophone of overhead should be the same whether using activity-based costing or traditional methods of cost allocation to products. The primary difference between activity-based costing and the traditional allocation methods is the amount of detail; particularly, the number of activities used to assign overhead costs to products. In practice, companies using activity-based costing generally use more than four activities because more than four activities are important.
Computing a Predetermined Overhead Rate
Although both of you produce the same total volume of ice cream, it is not hard to imagine that your friend’s overhead costs would be considerably higher. If the predetermined overhead rate calculated is nowhere close to being accurate, the decisions based on this rate will definitely be inaccurate, too. That is, if the predetermined overhead rate turns out to be inaccurate and the sales and production decisions are made based on this rate, then the decisions will be faulty. When there is a big difference between the actual and estimated overheads, unexpected expenses will definitely be incurred. Also, profits will be affected when sales and production decisions are based on an inaccurate overhead rate. Hence, it is essential to use rates that determine how much of the overhead costs are applied to each unit of production output.
As a result, the overhead costs that will be incurred in the actual production process will differ from this estimate. The activity base (also known as the allocation base or activity driver) in the formula for predetermined overhead rate is often direct labor costs, direct labor hours, or machine hours. That is, a number of possible allocation bases such as direct labor hours, direct labor dollars, or machine hours can be used for the denominator of the predetermined overhead rate equation. The predetermined overhead rate is calculated by dividing the estimated manufacturing overhead by the estimated activity base (direct labor hours, direct labor dollars, or machine hours).
Machine Hours Example
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. Management analyzes the costs and selects the activity as the estimated activity base because it drives the overhead costs of the unit. 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 Predetermined Overhead Rate Formula (With Excel Template)
Activity-based costing has revealed that low-volume, specialized products have been the cause of greater costs than managers had realized. 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. In these situations, a direct cost (labor) has been replaced by an overhead cost (e.g., depreciation on equipment).
Larger organizations may employ a different predetermined overhead rate in each production department, which tends to improve the accuracy of overhead application by employing a higher level of precision. However, the use of multiple predetermined overhead rates also increases the amount of required accounting labor. The predetermined overhead rate is used to price new products and to calculate variances in overhead costs. Hence, the overhead incurred in the actual production process will differ from this estimate. A predetermined overhead rate is an allocation rate given for indirect manufacturing costs that are involved in the production of a product (or several products).
The overhead used in the allocation is an estimate due to the timing considerations already discussed. One of the advantages of predetermined overhead rate is that it can help businesses monitor overhead rate. A business can calculate its actual costs periodically and then compare that to the predetermined overhead rate in order to monitor expenses throughout the year or see how on-target their original estimate was. This comparison can be used to monitor or predict expenses for the next project (or fiscal year). In larger companies, each department in which different production processes take place usually computes its own predetermined overhead rate. Despite the fact that it may become more complex, it is considered more accurate and helpful to have different predetermined overhead rates for each department, because the level of efficiency and precision increases.
