Formula
Target CPA = Revenue Per Conversion / Target ROAS
Target CPA estimates the maximum average acquisition cost that still supports a desired return level. It is useful for setting bidding targets, campaign guardrails, and scenario plans before spend goes live.
How to use this calculator
- 1Enter average revenue per conversion, order, or customer for the scenario you are planning.
- 2Enter target ROAS as a ratio such as 3.5 for 3.5x, not as a percentage.
- 3The calculator divides revenue per conversion by target ROAS to estimate the allowable CPA.
What this metric tells you
A lower target CPA means the campaign needs cheaper acquisitions to hit the desired return.
A higher revenue per conversion or a lower return target will allow a higher CPA ceiling.
Target CPA is most useful when paired with break-even thresholds and actual observed CPA to see whether your goals are realistic.
Common use cases
- Setting a target CPA before launching or scaling a campaign.
- Working backward from desired ROAS to an allowable acquisition cost.
- Building media plans and bidding guardrails from revenue assumptions.

Worked example
Example: calculating target CPA from revenue per conversion and target ROAS
If revenue per conversion is $120 and you want a 3.0x ROAS, target CPA is $40.00. That means each acquisition needs to stay around forty dollars or less on average to meet the goal.
FAQ
What is target CPA?+
Target CPA is the acquisition cost ceiling you aim to stay at or below in order to hit a desired return or efficiency goal.
How do you calculate target CPA from ROAS?+
You divide revenue per conversion by target ROAS. For example, $120 revenue per conversion and a 3.0x target ROAS give a $40 target CPA.
Should target CPA equal break-even CPA?+
Not usually. Break-even CPA is the floor. Target CPA is often set lower so there is room for margin, overhead, and reporting variability.
Can target CPA change by campaign type?+
Yes. Different campaigns can justify different target CPA levels depending on conversion quality, order value, customer value, and strategic importance.
