Definitions:

Efficiency Variance

The difference between the actual amount of resources used in production and the amount that was expected to be used, indicating the level of efficiency in using materials, labor, and overhead.

Denominator Level

A term used in cost accounting to describe the level at which fixed costs are allocated to units of production.

Predetermined Overhead Rate

A rate used to allocate manufacturing overhead costs to products, calculated before the period begins based on estimated costs.

Variable Overhead

Costs that vary with the level of production output, such as utilities or indirect materials, but are not directly traceable to a specific unit of product.
