Direct Costs and Indirect Costs. Manufacturing costs may be classified as direct costs and indirect costs on the basis of whether they can be attributed to the production of specific goods, services, departments or not. Direct costs can be defined as costs which can be accurately traced to a cost object with little effort. Cost object may be a product, a department, a project, etc. Direct costs typically benefit a single cost object therefore the classification of any cost either as direct or indirect is done by taking the cost object into perspective. A particular cost may be direct cost for one cost object but indirect cost for another cost object.
3. Multiply the amount of each worker's direct labor hours by the total amount of workers. Adding to the example above, say there were 100 direct labor workers for the job. Multiply 100 by the number of hours each worked, in this case 80. That comes to 8,000 direct labor hours. 4. Divide the full amount paid for direct labor by the full amount for direct labor hours. Keeping with the example, say you paid $108,000 for direct labor. Divide this amount by the 8,000 direct labor hours worked. The amount of the actual rate per direct labor hour is $13.50.
