Consumer Surplus

D - Microeconomics

Consumer surplus is the monetary gain a buyer receives when the price actually paid for a good is lower than the highest price the buyer would have been willing to pay for it, measured as the area beneath the demand curve and above the market price. Alfred Marshall popularized the concept in his Principles of Economics, building on earlier work by the engineer Jules Dupuit, and it remains the standard measure economists use to express how much value a market delivers to buyers rather than sellers.
