Indirect labor costs are not readily identifiable with a specific task or work order. They are termed indirect costs and are charged to overhead accounts. Use indirect labor in a sentence. At our plant most of our employees are direct labor and a smaller portion are indirect labor that are not directly involved in the production process.
Direct labor cost depends on the number of hours worked and the average hourly rate for labor directly involved in the manufacture of products. Overhead costs are indirect costs, such as administration and quality control. The selling price must be equal to at least the total direct and overhead costs to break even. Divide the overhead costs by the direct labor hours over the same measurement period. 2  In the example, the overhead rate is $20 for each direct labor hour ($2,000/100).
