Cost per acquisition calculates how much it costs to acquire a new customer, lead, or completed action. Businesses use CPA to measure advertising efficiency and profitability.

For example, if a campaign spends $500 and generates five signups, the CPA is $100. A strong performance program reduces CPA through better targeting, creative optimization, and conversion improvements rather than only lowering spend.
