The variable overhead efficiency variance measures the difference between the actual level of activity and the standard activity allowed for the actual output, multiplied by the fixed part of the predetermined overhead rate.

Variable Overhead Efficiency Variance

The difference between the actual and expected (or standard) variable overhead costs based on the actual production hours.

Standard Activity

A benchmark or norm for measuring performance or efficiency, often used in costing and budgeting processes.

Predetermined Overhead Rate

A rate used to allocate manufacturing overhead to individual products or job orders, calculated before the production period based on estimated costs and activity levels.
