Definitions:

Machine-Hours

A measure of production time, representing the total hours that machines are operated in the manufacturing process.

Manufacturing Overhead

All manufacturing costs that are not directly related to the production of goods, such as the cost of maintenance, heat, and light of the production facility.

Plantwide Predetermined Rate

A single overhead rate calculated by dividing total estimated manufacturing overhead costs by the total estimated amount of the allocation base, applied throughout an entire plant or facility.

Machine-Hours

The total number of hours that machinery is in operation, used as a basis for allocating manufacturing overhead costs in a production environment.
