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.
Definition: Direct labor is production or services labor that is assigned to a specific product, cost center, or work order.irect labor is considered to be a direct cost, which means that it varies directly with revenue or some other measure of activity.
