Decomposing Total Costs as Fixed Costs plus Variable Costs. Variable costs are costs that change in proportion to the good or service that a business produces. Variable costs are also the sum of marginal costs over all units produced. They can also be considered normal costs. Fixed costs and variable costs make up the two components of total cost.
Mixed costs or semi-variable costs have properties of both fixed and variable costs due to presence of both variable and fixed components in them. An example of mixed cost is telephone expense because it usually consists of a fixed component such as line rent and fixed subscription charges as well as variable cost charged per minute cost. Another example of mixed cost is delivery cost which has a fixed component of depreciation cost of trucks and a variable component of fuel expense.
