What is Consumer Surplus?

Consumer surplus represents the additional benefit or value that consumers receive when they pay less for a good or service than they are willing to pay. It is calculated as the difference between the maximum price a consumer is willing to pay (their individual valuation of the good) and the actual market price they end up paying.

When consumers are willing to pay a certain amount for a product but the market price is lower, they experience surplus because they are acquiring a product at a price that is below their maximum willingness to pay. This surplus is a crucial concept because it reflects the economic welfare that consumers gain from participating in the market. It provides insight into how much value consumers derive from transactions and can be used to assess the efficiency of market outcomes.

Understanding consumer surplus helps illustrate how pricing can affect purchasing behavior and overall market satisfaction. It highlights the benefits of competitive markets, where the price typically falls below consumers' maximum willingness to pay, increasing their level of satisfaction and economic well-being.
