Consumer surplus
Step-by-step explanation:
The consumer surplus is a measure of the difference between the price a consumer is willing to pay for a unit of a product and the price they actually pay for that product unit.
If a consumer is willing to to pay a higher amount than the actual selling price of a product, it is deduced that the consumer surplus for that product, is higher than if the consumer were charged for the product at his highest willingness point to pay.
