CPA Calculator
Calculate cost per acquisition and compare it with customer revenue or value.
CPA formula
CPA = acquisition spend ÷ customers acquired. It can be calculated for purchases, signups or another defined acquisition, but make sure your denominator matches the outcome you actually care about.
Compare CPA with economics
CPA by itself is incomplete. Compare it with gross contribution, customer lifetime value or another economic measure to understand whether acquisition is sustainable.
