How it works
- ROAS targets without cost visibility tend to produce false confidence.
- Break-even ROAS connects adjusted order revenue to the maximum CAC the order can tolerate.
- Fees and returns lower the CAC ceiling and push break-even ROAS higher.
- This tool is directional and should be validated with real channel economics before committing spend.
Common mistakes
- Using revenue instead of contribution economics.
- Ignoring returns or platform costs.
- Using blended numbers carelessly across unlike channels.
- Setting growth targets without profit thresholds.
