Quick Summary

In economics, fixed costs are expenses that remain constant and do not change with short-term fluctuations in production levels. These costs are distinct from variable costs, which directly fluctuate with changes in output. Examples of fixed costs include the expenses associated with leasing a building or maintaining heavy machinery.

Total cost is the sum of both fixed and variable costs incurred by a firm at a specific output level. While fixed costs remain stable, variable costs, such as labor and raw materials, change with production volume. In the long run, if fixed costs are unchanged, the rate at which variable costs increase with output may accelerate due to diminishing returns.

How costs are measured
These are called fixed costs. Other costs, like labor and raw materials, can increase or decrease depending on how much is produced. These are called variable costs.
