CPA Calculator
CPA (cost per acquisition, also called cost per action) is how much you pay, on average, for each conversion — a sale, lead, or sign-up. Toolverge uses CPA = total spend ÷ conversions, and can also solve for the budget needed at a target CPA and conversion goal, or the conversions a given spend and CPA imply. CPA is the bottom-of-funnel counterpart to CPC and CTR, tying spend directly to results.
How it works
- Choose what to solve for: CPA, budget (spend), or conversions.
- Enter the other two numbers. A $1,000 / 20 conversion example is filled in ($50 CPA).
- Read all three values on the tape.
Formula CPA = total spend / conversions

How is CPA different from CPC?
