Consumer and Producer Surplus
Consumer and producer surplus are key concepts in economics that measure the benefits to buyers and sellers in a market. Consumer surplus is the difference between what consumers are willing to pay for a good and what they actually pay, representing their extra benefit. Producer surplus is the difference between the price sellers receive and the minimum they would accept, reflecting their gain. Together, they illustrate the total welfare created by market transactions.

💡 Key Takeaways
- Define consumer surplus and producer surplus and why they matter for buyers and sellers.
- Consumer surplus is the extra value buyers get when the price is below their maximum willingness to pay (area between the demand curve and the price).
- Producer surplus is the extra earnings sellers get when the price is above their minimum acceptable price (area between the price and the supply curve).
- Market equilibrium tends to maximize total surplus, and price changes or taxes can reduce welfare by creating deadweight loss.
