Break-even ROAS calculator

Below break-even ROAS, each dollar of ad-driven revenue does not cover product cost plus ads. This uses gross margin only: a simple floor, not full contribution margin.

Your numbers

For example, 40 for 40%.

Optional: work margin out from one order. Used only when the margin field is blank.

How to read break-even vs platform ROAS

Break-even ROAS is 1 ÷ gross margin. At 40% margin, each $1 of revenue leaves $0.40 after product cost, so you need $2.50 of revenue for every $1 of ads just to stand still. That is 2.50x.

Compare it with a ROAS that counts each sale once, like MER from payment revenue. Next to summed Meta + Google ROAS, double-counting can make an account look above break-even when the money says otherwise.

It is a floor, not a target. Fixed costs, refunds and payment fees all sit on top.

Check it against real numbers

Size the double-count with the platform vs payment gap calculator, then work out the payment-verified ratio with the MER calculator. If MER sits below break-even, the ads are not paying for themselves yet, whatever the platform dashboards say.

Where Thexly fits

Thexly does not work out margin for you. It shows payment-verified revenue per client, live, so you have an honest number to hold against break-even. See how it works for agencies, or start free.
