People Also Ask

What is breakeven CPA?
Breakeven CPA is the maximum amount you can spend to acquire a customer while still making zero profit. Any CPA below this means you're profitable; above it means you're losing money per customer.
How do I calculate maximum allowable CPA?
For a target ROAS, divide your LTV by the target ROAS percentage. For example, with $10,000 LTV and 300% target ROAS, max CPA = $10,000 / 3 = $3,333.
Should I spend up to my breakeven CPA?
No. Operating at breakeven means zero profit. Set a target ROAS (typically 300%+) and calculate your max CPA accordingly. This ensures healthy profit margins while scaling.
