Overhead Rate Calculator
Calculate overhead allocation rate
About this calculator
An overhead rate calculator helps businesses determine the percentage of indirect costs that should be allocated to products or services. This essential financial tool calculates how much overhead expense should be assigned per dollar of direct costs, enabling accurate product pricing, cost analysis, and profitability assessment. By understanding your overhead allocation rate, you can make informed decisions about pricing strategies, budget planning, and resource allocation to maximize operational efficiency and maintain competitive margins.
How to use
Enter your total overhead costs (rent, utilities, administrative expenses, etc.) and your allocation base (direct labor costs, machine hours, or direct materials). The calculator will divide total overhead by the allocation base to determine your overhead rate percentage. Use this rate to allocate indirect costs proportionally across your products or services.

What allocation base should I use?
Common allocation bases include direct labor hours, direct labor costs, machine hours, or direct materials costs. Choose the base that best correlates with your overhead consumption.
