1. What Is Consumer Surplus?

Consumer surplus is an economic measure of consumer benefit. It represents the difference between what consumers are willing to pay for a good or service (their maximum willingness) and what they actually pay (the market price).

2. How The Calculator Works

The calculator uses the consumer surplus formula:

Where:

• \( CS \) — Consumer Surplus ($)
• \( MW \) — Maximum Willingness to Pay ($)
• \( AP \) — Actual Price ($)

Explanation: This simple calculation shows the economic benefit consumers receive when they pay less for a product than the maximum amount they were willing to pay.

3. Importance Of Consumer Surplus

Details: Consumer surplus is a key concept in welfare economics. It helps measure economic welfare, assess market efficiency, and evaluate the impact of government policies like taxes and subsidies on consumer welfare.

4. Using The Calculator

Tips: Enter the maximum amount you would be willing to pay for a product and the actual price you paid. Both values must be positive numbers. The calculator will show your consumer surplus in dollars.
