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.
Manufacturing companies have direct and indirect costs. The company generates direct costs in the factory where it manufactures its products, while indirect costs are the costs it generates everywhere else. Direct costs consist of the materials used to make the products and the labor used to assemble them. Direct labor usually is paid hourly, and the costs consist of wages, payroll taxes, and benefits. They are variable costs, since they depend on the number of units produced; the greater the amount of production, the greater number of man-hours required.
