Direct Labor Time Variance

The difference between the actual labor time spent on a product and the standard labor time expected, affecting product costs.

Standard Costs

Predetermined or estimated costs that are used as benchmarks for measuring the performance of actual costs in manufacturing or production.

Actual Costs

Actual costs are the real or true costs incurred for materials, labor, and overhead in the production of goods or provision of services, as opposed to estimated or standard costs.
