Example of a Predetermined Overhead Rate
It’s important to note that the predetermined factory overhead rate is based on estimates and assumptions. Actual overhead costs may differ from the estimates, resulting in variances that need to be accounted for at the end of the period. Regular monitoring and analysis of the overhead allocation process help ensure the accuracy of the predetermined rates and provide insights into the cost behavior within the manufacturing process. As you have learned, the overhead needs to be allocated to the manufactured product in a systematic and rational manner.
Examples of predetermined overhead rate

By leveraging Flxpoint’s comprehensive platform, businesses can effectively reduce overhead costs, leading to improved profitability and operational efficiency. So the company would apply $5 of overhead cost to the cost of each unit produced. Enhance your proficiency in Excel and automation tools to streamline financial planning processes. Learn through real-world case studies and gain insights into the role of FP&A in mergers, acquisitions, and investment strategies.
- This $4 per DLH rate would then be used to apply overhead to production in the accounting period.
- In summary, overhead rates have a sizable impact on a company’s key financial statements and decisions.
- At a later stage, when the actual expenses are known, the difference between that allocated overhead and the actual expense is adjusted.
- Predetermined overheads rate is the ratio of estimated overhead cost to the estimated units to be allocated and is used for allocation of expenses across its cost centers and can be fixed, variable or semi-variable.
- The use of a predetermined factory overhead rate provides a practical way to allocate overhead costs to products or cost objects without waiting for the actual costs to be determined.
Using a Single Rate for Different Departments

E-commerce businesses typically have different overhead structures – they might have higher technology and website maintenance costs but lower physical store expenses. In a company, the management wants to calculate the predetermined overhead to set aside some amount for the allocation of a cost unit. Therefore, they use labor hours for the apportionment of their manufacturing cost. Overhead rates are an important concept in cost accounting and business analysis. By properly calculating and applying overhead rates, businesses can accurately assess the true costs of their operations. As shown in Figure 3.3 “Using Department Rates to Allocate SailRite Company’s Overhead”, products going through the Hull Fabrication department are charged $50 in overhead costs for each machine hour used.


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 QuickBooks then allocating those costs to the units produced during that period. It’s important to note that this is an estimated rate, and actual overhead costs and the actual activity base can be different from the estimated figures. Therefore, at the end of the period, there might be an underapplied or overapplied overhead, which must be adjusted.
The application rate that will be used in a coming period, such as the next year, is often estimated months before the actual overhead costs are experienced. Often, the actual overhead costs experienced in the coming period are higher or lower than those budgeted when the estimated overhead rate or rates were determined. At this point, do not be concerned about the accuracy of the future financial statements that will be created using these estimated overhead allocation rates. You will learn in Determine and Disposed of Underapplied or Overapplied Overhead how to the predetermined overhead allocation rate is the rate used to adjust for the difference between the allocated amount and the actual amount. Moreover, predetermined overhead cost rates enhance budgetary control and financial planning by providing a clear framework for managing overhead expenses.
