Direct Cost: A direct cost which is directly identified with the object we are trying to cost. Usually, Direct cost is the combined cost of Direct Material Cost, Direct Labor Cost, and Direct Expenses.
Direct Material Cost: Any material, component, or raw material which is directly utilized to manufacture any unit of product or good is Direct Material. For example, suppose that a fixtures maker is defining the cost of a wooden chair. The manufacture of the chair has involved the use of wood, bolts and metallic drawer handles.
Direct Labor Cost: Any wages paid to the machine operator, assembler or finisher who are directly involved to produce a unit of product or good for instance chair.
Direct Expenses: Direct expense would be the payment made to the designer of the chair who may be entitled to a royalty payment for each chair made.
Indirect Cost: All cost other than Direct Cost is classified as Indirect Cost. Although it is incurred in the production of the chair, it cannot be directly attributed to a particular cost unit. Examples are as follows:
| COST Incurred | Cost Classification |
| Material related to Lubrication Oils and Cleaning Material | Indirect Material Cost |
| Salaries of Floor Supervisor | Indirect Labor Cost |
| Rent of Factory, Power | Indirect Expense |
It is important to understand that a particular cost may sometimes be direct cost and sometimes an indirect cost depending on the cost object.
