How to Use This Calculator
Breakeven CPA
This is the maximum cost per acquisition before you start losing money. If your Google Ads CPA is above this number, every sale is unprofitable.
Breakeven ROAS
The minimum return on ad spend needed to break even. Anything below this ROAS means you're spending more on ads than you're making back.
Target CPA & ROAS
These factor in your desired profit margin. Set your Google Ads bid strategies to these targets to ensure you're actually making money, not just breaking even.
Single vs. LTV
Single purchase targets assume each customer buys once. LTV targets factor in repeat purchases, giving you more room to spend on acquisition if your customers come back.
