However, there is a strong need to constantly update the production level depending on the seasonal fluctuations and the factor affecting the demand of the product. Detailed cost analysis helps to estimate the cost of overheads with accuracy. Further, customized input from different departments can be obtained to enhance the accuracy of the budget. There are several reasons why businesses need to calculate a predetermined overhead rate. Two companies, Certified Bookkeeper ABC company, and XYZ company are competing to get a massive order that will make them much recognized in the market.
Why Do We Need to Calculate Predetermined Overhead Rate?
(b) Alternatively, we use machine hour rate if in the factory or department of the production is mainly controlled or dictated by machines. This can result in abnormal losses as well and unexpected expenses being incurred. Also, if the rates determined are nowhere close to being accurate, the decisions based on those rates will be inaccurate, too.

This is why a predetermined overhead rate is computed to allocate the overhead costs to the production output in order to determine a cost for a product. The predetermined overhead rate is, therefore, usually used for contract bidding, product pricing, and allocation of resources within a company, based on each department’s utilization of resources. During the year, if XYZ produces a table that requires 4 direct labor hours, $40 ($10 per hour x 4 hours) of overhead costs would be allocated to that table. Calculating the Predetermined Overhead Rate (POR) is a critical step in cost accounting, particularly in the manufacturing sector. It involves estimating the manufacturing overhead costs that will be incurred over a specific period and then allocating those costs to the units produced during that period.

- 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.
- A predetermined overhead rate is a crucial concept in cost accounting that helps allocate indirect manufacturing costs to products or services.
- The formula for calculating Predetermined Overhead Rate is represented as follows.
- The predetermined rate usually be calculated at the beginning of the accounting period by relying on the management experience and prior year data.
This can be best estimated by obtaining a break-up of the last year’s actual cost and incorporating seasonal effects of the current period. Predetermined overhead rates are also used in the budgeting process of a business. As discussed above, a business must wait until the end of a period to know the actual performance in terms of overheads incurred. However, since budgets are made at the start of the period, they do not allow the business to use actual results for planning or forecasting. Therefore, the business must use a predetermined overhead rate to budget its expenses for the future. Many accountants always ask about specific time which we need to do this, at what point in time is the predetermined overhead rate calculated.

As is apparent from both calculations, using different basis will give different results. The price using units of production as a What is Legal E-Billing basis is $47,500 while the price using labor hours as a basis is $46,250. For some companies, the difference will be very minute or there will be no difference at all between different basis while for some other companies the differences will be significant. Therefore, a company should choose the basis for its predetermined overhead rates carefully after considering all the factors. Before the beginning of any accounting year, it is determined to estimate the level of activity and the amount of overhead required to allocate the same.
- (b) Alternatively, we use machine hour rate if in the factory or department of the production is mainly controlled or dictated by machines.
- The price a business charges its customers is usually negotiated or decided based on the cost of manufacturing.
- Predetermined overhead rates are also used in the budgeting process of a business.
- Furthermore, when actual costs are compared to the budgeted costs based on predetermined overhead rates, the variances may be too significant.
- The predetermined overhead rate formula can be used to balance expenses with production costs and sales.
- 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.
