Cost-per-acquisition formulas
CPA = attributed cost ÷ acquisitions. Reverse modes use cost = CPA × acquisitions and acquisitions = cost ÷ CPA.
Worked example
$10,000 divided by 250 acquisitions gives a $40 CPA.
Define the denominator
An acquisition may mean a customer, lead, or conversion depending on your organization. The result does not establish profitability, lifetime value, attribution quality, or campaign recommendations.
