The machine hour rate is a method for allocating overhead costs based on machine hours. It is calculated by dividing the total overhead costs by the total expected machine hours. Overhead costs that are allocated this way include depreciation, rent, utilities, maintenance, wages, and more. The machine hour rate breaks costs into standing charges that are fixed and machine charges that are variable based on machine usage. This method allows companies to measure machine efficiency, track idle time, and estimate costs.
