Standard Cost System

A cost accounting method that assigns expected costs to products to help in setting budgets and analyzing cost variances.

Volume Variance

The variance that arises whenever the standard hours allowed for the actual output of a period are different from the denominator activity level that was used to compute the predetermined overhead rate. It is computed by multiplying the fixed component of the predetermined overhead rate by the difference between the denominator hours and the standard hours allowed for the actual output.

Variable Manufacturing Overhead

Costs that fluctuate with production volume, such as indirect materials, indirect labor, and other expenses that increase or decrease as production levels change.

Fixed Manufacturing Overhead

Costs related to production that do not vary with the level of output, including salaries of permanent staff and rent of factory premises.
