How do you calculate break-even ROAS?

Divide 1 by your contribution margin expressed as a decimal. A 40% contribution margin produces a 2.5x break-even ROAS.

Should returns and payment fees be included?

Yes. Include every variable cost that rises with an order, including product cost, fulfillment, payment fees, discounts, and an expected return allowance.

Q: What is break-even ROAS?

Break-even ROAS is the revenue-to-ad-spend ratio where contribution profit after variable costs exactly covers advertising cost.

Find the return your ads must clear before they make money, with the costs your ad dashboard leaves out.

The formula

What is break-even ROAS?

Break-even ROAS is the revenue-to-ad-spend ratio where your contribution profit exactly covers advertising cost. Above it, each order creates contribution profit. Below it, scaling ads scales the loss.

Worked example

A 40% margin needs 2.5x ROAS just to stand still.

Per $100 orderAmountRunning margin

Revenue$100100%

Product cost-$4258%

Fulfillment, fees, returns-$1840%

Maximum ad spend$402.50x ROAS

The ad platform may report 2.2x as a strong return. Your ledger says it loses $4.55 on every $100 order before overhead.

Break-even ROAS FAQ

What is a good break-even ROAS?

Lower is generally more resilient because each revenue dollar leaves more room for ad spend. There is no universal target: a 1.5x floor may be healthy for a high-margin brand, while a 4x floor may be unavoidable in a thin-margin category.

What is the difference between break-even ROAS and target ROAS?

Break-even ROAS is the no-profit, no-loss floor. Target ROAS should sit above that floor to fund overhead, payroll, reinvestment, and the profit you expect the business to keep.

Does break-even ROAS include fixed overhead?

This calculator focuses on variable contribution economics. To build a target ROAS that covers fixed overhead, add your desired overhead allocation and profit per order to the contribution you need to retain.

Can I use this for lead generation?

Yes, if you translate expected customer value into revenue per acquired customer and include the variable costs of delivery. For a pure lead metric, maximum CPA is usually the more direct output.

Why does Meta or Google Ads ROAS differ from my profit?

Ad platforms compare attributed revenue with ad spend. They do not subtract product cost, fulfillment, payment fees, returns, or discounts, so reported ROAS can look healthy while contribution profit is negative.
