Consumer Surplus – Definition & Examples

Definition: The difference between what consumers are willing to pay for a good and what they actually pay.

Detailed Explanation

Consumer surplus represents the 'bonus' buyers get from market transactions. If you'd pay $50 for a concert ticket but get it for $30, your consumer surplus is $20. On a graph, it's the triangle between the demand curve and the market price. Efficient markets maximize total surplus (consumer + producer surplus).

Real-World Example

During Black Friday sales, consumer surplus skyrockets. A TV you'd pay $800 for sells at $400, giving you $400 in consumer surplus—that's why people camp outside stores.

AP Economics Relevance

Consumer surplus is central to welfare economics on AP exams. You'll calculate it graphically and analyze how policies like taxes and price controls affect it.

How to Remember It

The difference between what consumers are willing to pay for a good and what they actually pay. A useful definition should do more than name the concept. Try to describe Consumer Surplus – 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.
