Fixed Cost – Definition & Examples

Definition: Costs that do not change with the level of output produced, at least in the short run.

Detailed Explanation

Fixed costs must be paid regardless of production level—even if output is zero. Examples include rent, insurance, loan payments, and salaried employees. In the short run, fixed costs are 'sunk'—they shouldn't affect production decisions. In the long run, all costs become variable as firms can expand or exit.

Real-World Example

A gym pays $10,000 monthly rent whether it has 100 or 1,000 members. The rent is fixed—it doesn't depend on how many people work out.

AP Economics Relevance

Distinguishing fixed from variable costs is essential for understanding cost curves and shutdown decisions in AP Micro.

How to Remember It

Costs that do not change with the level of output produced, at least in the short run. A useful definition should do more than name the concept. Try to describe Fixed Cost – Definition & Examples in your own words, give one real-world example, and name one situation where confusing it with a related term would lead to the wrong answer. That habit is especially helpful for AP, IB, and introductory college economics.
