Total Variable Overhead Spending Variance

The variance between real variable overhead expenses and the anticipated expenses, which are determined using standard rates and the actual levels of production.

Variable Manufacturing Overhead

Indirect manufacturing costs that vary with production volume, such as utilities for the manufacturing plant or raw material handling costs.

Variable Overhead Rate Variance

The difference between the actual variable overhead costs incurred and the standard cost expected for the actual production volume.

Direct Labor-hours

The total hours of labor directly involved in the production of goods, often used as a basis for allocating manufacturing overhead in process costing.
