Break-Even ROAS

What This Page Answers

Break-even ROAS is the minimum return on ad spend needed to avoid losing money before considering longer-term value. It depends on contribution margin, not revenue alone.

Formula

Break-even ROAS = 1 / contribution margin

If contribution margin is 40%:

1 / 0.40 = 2.5 break-even ROAS

The campaign needs at least 2.5 ROAS to break even on first-order contribution.

Why It Matters

A 3.0 ROAS can be excellent for a high-margin product and unprofitable for a low-margin product. Break-even ROAS helps connect ad performance to actual economics.

What To Include In Margin

Consider:

  • Cost of goods sold

  • Payment processing

  • Shipping and fulfillment

  • Returns

  • Discounts

  • Platform fees

  • Sales costs where relevant

First-Order vs LTV ROAS

Some businesses can accept below break-even first-order ROAS if customers repeat, subscribe, or expand. But that decision requires:

  • Reliable LTV

  • Acceptable payback period

  • Cash flow tolerance

  • Retention confidence

Practical Rule

Never set a ROAS target without knowing margin. ROAS without margin is just revenue attribution.
