A consumer surplus occurs when a product or service costs less than customers are willing to pay.

It measures the additional advantage consumers gain by paying less than they were willing to spend.

Consumer surplus = (½) x Qd x ΔP
Qd = Supply and demand balance.

ΔP = Pmax – Pd, or the price at equilibrium where supply and demand are equal.

Pmax = The highest price a person is willing to pay.
