Price elasticity of demand is to total revenue as consumer surplus is to what?

Price elasticity of demand tells us how much the quantity demanded of a product changes when its price changes. When demand is elastic, a small price decrease can lead to a large increase in total revenue, while inelastic demand means that total revenue might not change much with price changes. Similarly, consumer surplus is related to how much benefit consumers get from purchasing a product at a lower price than they are willing to pay. Just as price elasticity affects total revenue, consumer surplus can be thought of in relation to producer surplus, which represents the benefit producers receive when selling at a higher price than their minimum acceptable price. For example, if a consumer is willing to pay $10 for a toy but buys it for $7, their consumer surplus is $3, while the producer's surplus is the difference between their cost and the selling price.
