ROAS & Break-even

Break-even ROAS Explained: What It Is and How to Calculate It

Break-even ROAS is the minimum return on ad spend where your campaign stops losing money after product costs — not the revenue number your ad platform shows by default.

What is break-even ROAS? (breakeven ROAS meaning)

To run your numbers, use the Break Even ROAS Calculator.

ROAS (return on ad spend) is revenue divided by ad spend. Break-even ROAS is the ROAS where contribution margin equals ad spend — profit after product costs is zero. Any ROAS below that threshold means you lose money on each conversion, even when revenue looks healthy.

Key insight: Platform ROAS uses gross revenue. Break-even ROAS uses contribution margin. They are not the same number.

The break-even ROAS formula

First find contribution per conversion: value times gross margin percent, minus any fixed cost per order or per lead.

Contribution = (value × margin%) − fixed cost

Break-even ROAS = value ÷ contribution

With no fixed costs, this simplifies to 1 ÷ margin. Fifty percent margin means 2.0× break-even ROAS. Twenty-five percent margin means 4.0×.

Worked example (ecommerce)

AOV $90, gross margin 50%, shipping and fees $6 per order.

  1. Contribution = ($90 × 0.50) − $6 = $39
  2. Break-even ROAS = $90 ÷ $39 = 2.31×
  3. At 2.0× platform ROAS, the campaign loses money despite $180 revenue on $90 spend

Apply the formula above with your own AOV, margin, and fixed costs per order.

Lead gen: use expected revenue per lead

For lead gen, value is expected revenue per lead: customer or deal value multiplied by close rate. A $5,000 deal at 15% close rate has $750 expected value per lead. Apply the same formula to that value.

Conversion rate on the landing page does not change break-even ROAS — only margin and value per conversion matter.

Frequently asked questions

What is break-even ROAS?
Break-even ROAS is the minimum ROAS where ad spend equals contribution margin per conversion. Below it, campaigns lose money after product or fulfillment costs.
What is breakeven ROAS meaning?
Breakeven ROAS means the same as break-even ROAS: zero profit after COGS and per-order fees. It is not the same as platform revenue ROAS.
How do I calculate break-even ROAS?
Divide value (AOV or expected revenue per lead) by contribution per conversion. Contribution equals value times margin percent minus fixed costs.
How does contribution margin set break-even ROAS?
Contribution margin per conversion is the denominator. Break-even ROAS = value ÷ contribution. Higher contribution lowers the ROAS you need.
Does conversion rate affect break-even ROAS?
No. Conversion rate affects max CPC and volume, but break-even ROAS depends only on margin and value per conversion.
Is break-even ROAS the same as target ROAS?
Break-even ROAS is your floor. Target ROAS in ad platforms should be at or above this number — often higher if you want profit, not just break-even.
