Fixed Cost. Definition: A fixed cost is a cost that does not vary in the short term, irrespective of changes in production or sales levels, or other measures of activity. A fixed cost is a basic operating expense of a business that cannot be avoided, such as a rent payment.
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. A T C = A V C + A F C {\displaystyle ATC=AVC+AFC}.
