Recall the definition of consumer surplus: it is the difference between what consumers are willing to pay for a good (represented by the demand curve) and what they actually pay (the market price).
Identify the equilibrium price and quantity on the graph where the demand and supply curves intersect.
Understand that consumer surplus is the area between the demand curve and the equilibrium price line, extending from zero to the equilibrium quantity.
Visualize this area as a triangle or shape bounded above by the demand curve, below by the horizontal line at the equilibrium price, and vertically by the quantity sold.
Confirm that this area represents the total benefit consumers receive over and above the amount they pay at equilibrium.
