How to read this

From spend to profit, in plain English

ROAS
is revenue ÷ ad spend, shown as a multiple. A 4× means every $1 of ad spend returned $4 of revenue — before costs.
ROI %
is (revenue − spend) ÷ spend. It's the top-line return as a percentage, ignoring margin.
Net after ad spend
is your gross profit (revenue × margin) minus the ad spend. This is the number that tells you if the campaign actually made money.
Break-even ROAS
is 1 ÷ margin. Beat it and you profit; fall below it and you lose money on every sale. The verdict compares your actual ROAS to this line — green above, amber within 10%, red below.
Max profitable CPA
(when AOV is set) is the most you can pay to acquire one customer and still break even: AOV × margin.

ROAS questions

Asked, answered.

What is a good ROAS?+

There's no universal number — a good ROAS is any ROAS above your break-even ROAS, which depends on your profit margin. At a 30% margin you break even at roughly 3.33×, so anything above that is profit. Lower-margin businesses need a higher ROAS to stay profitable, while high-margin software can be healthy at 2×. Always compare actual ROAS to your own break-even, not to a generic benchmark.

How is ROAS different from ROI?+

ROAS is revenue divided by ad spend, shown as a multiple like 4×, so it ignores margin and counts top-line return. ROI is profit relative to spend, shown as a percentage, so it reflects what you actually keep. A campaign can show a strong ROAS yet a thin or negative ROI once cost of goods and margin are factored in — which is why this calculator reports both.

How do I calculate break-even ROAS?+

Break-even ROAS is 1 divided by your profit margin expressed as a decimal. At a 25% margin that's 1 ÷ 0.25 = 4×, meaning every dollar of ad spend must return four dollars of revenue just to cover costs. Beat that number and you're profitable; fall below it and you're losing money on every sale, even if the campaign looks busy.
