Break-even ROAS Calculator

Estimate the ROAS required to break even after variable costs, fees, and returns.

Inputs

Start with adjusted order revenue, add non-ad variable costs, then pressure-test CAC tolerance.

Break-even is a ceiling, not a target operating state.

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.
