A related concept is marginal cost. Average fixed cost is the total fixed cost per unit of output incurred when a firm engages in short-run production. It can be found in two ways. Because average fixed cost is total fixed cost per unit of output, it can be found by dividing total fixed cost by the quantity of output.
Average fixed cost. In economics, average fixed cost (AFC) is the fixed costs of production (FC) divided by the quantity (Q) of output produced. Fixed costs are those costs that must be incurred in fixed quantity regardless of the level of output produced. Average fixed cost is a per-unit-of-output measure of fixed costs. As the total number of units of the good produced increases, the average fixed cost decreases because the same amount of fixed costs is being spread over a larger number of units of output.
