how to determine predetermined overhead rate

Not only profit, but it is also useful in other types of variance analysis. 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. The total number of units produced varies and is often known sooner than the cost of overhead. For example, a company may know it will have a contract to produce 100 custom units long before it knows the utility costs for the next year.

They divide $35,000,000 by 150,000, the number of direct labor hours, which equals $233 per hour. Predetermined overhead rate provides companies with a percentage they can monitor on a quarterly, monthly and even weekly basis, with the amount of base and expense being proportionate to each other. Similar absorption problems would result if actual cost incurred for repairs and maintenance were charged directly to a job or product processed during the month when the repairs were done. Ordinarily, repairs are necessary be­cause of wear and tear over a much larger period than one month and are done to permit continuous production.

This allocation process depends on the use of a cost driver, which drives the production activity’s cost. 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. Companies typically base their predetermined overhead rateson the estimated, or budgeted, amount of allocation base for the upcoming period. This is the method that is used in this chapter, but it is practice that is recently come under severe criticism. Direct labor standard rate, machine hours standard rate, and direct labor hours standard rate are some methods of factory overhead absorption. There are concerns that the rate may not be accurate, as it is based on estimates rather than actual data.

Why are predetermined overhead rates used at the beginning of the year?

A predetermined overhead rate 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.

The overhead rate for the packaging department is calculated by taking the estimated manufacturing overhead cost and dividing it by the estimated direct labor cost. The company actually had $300,000 in total manufacturing overhead costs for the year, and the actual machine hours used were 53,000. Predetermined overhead rates can be used with advantage for both job order and process cost accounting. These estimates are based on the previous year’s overhead costs and direct labor hours and are adjusted for expected increases in demand the coming year. Kline Company expects to incur $800,000 in overhead costs this coming year—$200,000 in the Cut and Polish department and $600,000 in the Quality Control department. The Cut and Polish department expects to use 25,000 machine hours, and the Quality Control department plans to utilize 50,000 hours of direct labor time for the year.

Thus the benefits of having improved cost information must outweigh the costs of obtaining the information. As we move on to more complex costing systems, remember that these systems are more expensive to implement. Kevin Johnston writes for Ameriprise Financial, the Rutgers University MBA Program and Evan Carmichael. Isobel Phillips has been writing technical documentation, marketing and educational resources since 1980.

One of the most common examples is rent, which remains static no matter how many goods are produced. To conclude, the predetermined rate is helpful for making decisions, but other factors should be taken into consideration, too. Writing professionally since 2004, Charmayne Smith focuses on corporate materials such as training manuals, business plans, grant applications and technical manuals. Smith’s articles have appeared in the “Houston Chronicle” and on various websites, drawing on her extensive experience in corporate management and property/casualty insurance. Who can explain for me the difference between over-applied overhead and under-applied overhead. After reviewing the product cost and consulting with the marketing department, the sales prices were set. The sales price, cost of each product, and resulting gross profit are shown in Figure 6.6.

Calculating Predetermined Overhead Rate

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. A predetermined overhead rate, also known as a plant-wide overhead rate, is a calculation used to determine how much of the total manufacturing overhead cost will be attributed to each unit of product manufactured. The rate is determined by dividing the fixed overhead cost by the estimated number of direct labor hours. For example, if the annual budget is based on a production quantity of 10,000 units and the direct labor required for each unit is three hours, the total direct labor is 10,000 x 3 or 30,000 hours.

The use of this rate allows the management to avoid the actual manufacturing overhead costs for the year-end closing process. The predetermined overhead rate formula is calculated by dividing the total estimated overhead costs for the period by the estimated activity base.

The overhead used in the allocation is an estimate due to the timing considerations already discussed. 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. A predetermined overhead rate is an allocation rate given for indirect manufacturing costs that are involved in the production of a product . According to a survey 34% of the manufacturing businesses use a single plant wide overhead rate, 44% use multiple overhead rates and rest of the companies use activity based costing system. The predetermined overhead rate is applied for each direct labor hour worked.

  • Since the amount of actual overhead is more than the forecasted overhead, the manufacturer has over-absorbed its overhead costs.
  • It will have a huge impact on inventory and cost of goods sold.Rely on management estimationThis method relies on the management team who will try to make the financial statement look good.
  • This allocation process depends on the use of a cost driver, which drives the production activity’s cost.
  • However, in recent years the manufacturing operations have started to use machine hours more predominantly as the allocation base.
  • Assume Kline Company allocates overhead costs with the plantwide approach, and direct labor cost is the allocation base.
  • Cost accountants aim to average out these variations through the use of a predetermined overhead rate calculated on an annual basis.

She also writes on personal development for the website UnleashYourGrowth. Phillips is a qualified accountant, has lectured in accounting, math, English and information technology and holds a Bachelor of Arts honors degree in English from the University of Leeds. Equipped with these predetermined overhead rate software tools, you can also more effectively perform needs analysis to further reduce overhead. We saved more than $1 million on our spend in the first year and just recently identified an opportunity to save about $10,000 every month on recurring expenses with PLANERGY.

The cost of manufacturing products includes more than labor, machinery and supplies. Your company has additional overhead for expenses like utilities, loan payments, insurance and lease payments. This overhead can be figured in such a way that you price each product to pay its share of overhead. In other words, this predetermined overhead rate is part of the cost of each product. Your calculations of expenses become much more accurate when you include predetermined overhead. In order to find the overhead rate we will use the same basis that we have chosen by multiplying this basis by the calculated rate.

The total overhead expenditure is then divided by the total labor hours to arrive at the overhead rate. If, in the example, total overhead amounts to $120,000 a year, the overhead rate will be $120,000 divided by 30,000 hours, or $4 per hour.


The formula for the predetermined overhead rate is purely based on estimates. Hence, the overhead incurred in the actual production process will differ from this estimate. Dina Inc. management has estimated the factory overhead cost as $1090 variable cost and $1430 fixed cost to make 100 units using 500 machine hours. Job 31 has a direct materials cost of $390 and a total manufacturing cost of $1,260. Overhead is applied to jobs at a rate of 200 percent of direct labor cost. The overhead rate of cutting department is based on machine hours and that of finishing department on direct labor cost.
