Cost terms, Concepts and Classifications Topic Two by Dr. Ong Tze San tzesan@econ.upm.edu.my
Variable and Fixed Cost • Variable cost is a cost that varies in total in direct proportion to changes in activity. • Fixed cost is a cost that remains constant in total within the relevant range of activity
Cost Objects • A cost object is any activity for which a separate measurement of cost is required (e.g. cost of making a product or providing a service).
Direct costs Costs that can beeasily and conveniently traced to a unit of product or other cost object. Examples: direct material and direct labor E.g. Wood to make furniture, hours worked on project, flour to make cake. Indirect costs Costs that cannot be easily and conveniently traced to a unit of product or other cost object. Example: manufacturing overhead E.g. rent of a factory that make cars/furniture, manager’s salary. Direct and Indirect Costs
Cost Drivers • A cost driver is an activity or occurrence that has a direct cause-effect relationship with a cost. • E.g. Production volume (units) has a direct effect on the total cost of raw materials used. • A change in production volume causes a similar change in the cost of raw materials
Control and Uncontrollable costs • Controllable costs are those costs that can be saved by not adopting a given alternative. • Uncontrollable costs are those costs that cannot be saved. • Example: send a salesman to Penang for business trip. Alternatives available: drive or fly. Controllable costs: petrol/air ticket Uncontrollable costs: salary, insurance
