In economics and cost accounting, total cost (TC) describes the total economic cost of production and is made up of variable costs, which vary according to the quantity of a good produced and include inputs such as labor and raw materials, plus fixed costs, which are independent of the quantity of a good produced and include inputs (capital) that cannot be varied in the short term, such as buildings and machinery.
Total cost in economics includes the total opportunity cost of each factor of production as part of its fixed or variable costs.
The rate at which total cost changes as the amount produced changes is called marginal cost. This is also known as the marginal unit variable cost.
If one assumes that the unit variable cost is constant, as in cost-volume-profit analysis developed and used in cost accounting by the accountants, then total cost is linear in volume, and given by: total cost = fixed costs + unit variable cost * amount.
The total cost of producing a specific level of output is the cost of all the factors of input used. Conventionally, economists use models with two inputs: capital, K; and labor, L. Capital is assumed to be the fixed input, meaning that the amount of capital used does not vary with the level of production. The rental price per unit of capital is denoted r. Thus, the total fixed costs equal Kr. Labor is the variable input, meaning that the amount of labor used varies with the level of output. In fact, in the short run, the only way to vary output is by varying the amount of the variable input. Labor is denoted L and the per unit cost, or wage rate, is denoted w, so the total variable costs is Lw. Consequently, total cost is fixed costs (FC) plus variable cost (VC), or TC = FC + VC = Kr +wL.

When a firm has time to expand or reduce the amount of capital and land it employs in its production, it may find its average, per-unit production costs either rising or falling with the amount of capital it uses. This phenomenon is known as economies of scale (or size). Sometimes, the larger a firm becomes, the more it produces, the lower its average costs of production. On the other hand, it is possible for a firm to become too big for its own good, and experience diseconomies of scale: when producing more output leads to rising average costs. This lesson distinguishes between a firm's short-run average total cost and its long-run average total cost, and explains how economies of scale may help a firm achieve lower average costs as it increases its output in the long-run.
