In economics, consumer surplus is a fundamental concept that reflects the benefit consumers receive when they pay less for a product than what they were willing to pay. It is a measure of consumer welfare and market efficiency. When you hear someone say, “That was a great deal,” they’re unknowingly referring to consumer surplus.

Whether you’re a student learning microeconomics, a business owner analyzing market behavior, or just a curious consumer, this calculator provides instant insights with minimal input.
What is Consumer Surplus?
Consumer surplus is the difference between the highest price a consumer is willing to pay for a good or service and the actual price they pay.
Formula (Simple Text Format):
Consumer Surplus = Maximum Price Willing to Pay − Actual Price Paid
This surplus represents the extra value or savings the consumer enjoys due to favorable market pricing.
