CPA = Advertising cost ÷ Attributed acquisitions
Use consistent periods and units throughout the calculation. When rates are entered as percentages, convert them to decimals for arithmetic unless the interface performs that conversion automatically.
What the result means
It converts the entered assumptions into a consistent estimate of google ads cpa. The result is most useful for comparison and planning when every input covers the same scope.
Compare CPA with contribution profit or customer lifetime value, not revenue alone. Recalculate when the underlying inputs change, and use source records rather than memory for material decisions.
$9,600 in spend producing 240 acquisitions yields a $40 CPA.
The example illustrates the mechanics only. Replace every example value with data that reflects the user’s actual period, account, policy, or scenario.
