Definitions:

Labor Price Variance

The difference between the actual cost of labor and the budgeted or standard cost of labor, used in budgeting and cost management.

Materials Quantity Variance

The difference between the actual quantity of materials used in production and the expected amount, which can indicate efficiency or waste.

Standard Price

The predetermined cost assigned to materials, labor, and overhead, used in budgeting and variance analysis.

Labor Variances

Differences between the actual labor costs incurred during production and the standard or expected labor costs, which can indicate efficiencies or inefficiencies.
