Informational purposes only
Everything published on ROAS Calculator — the calculator, the formulas, the benchmark examples and the guidance articles — is provided for general information and education. It does not constitute financial, investment, accounting, tax, legal or business advice, and it is not a recommendation to take or refrain from any commercial action.
No professional relationship
Using this site does not create an advisor–client relationship of any kind. Before acting on any number produced here, consult an accountant, a tax adviser or another qualified professional who knows your specific situation.
The limits of the calculation
The results are pure arithmetic applied to the three figures you type in. They are only as good as those inputs, and they deliberately ignore everything you did not enter. In particular, a result here does not account for:
- fixed costs — salaries, rent, software, agency retainers;
- taxes of any kind, including VAT, sales tax and corporate income tax;
- refunds, chargebacks and returns after the measurement window;
- attribution error — ad platforms routinely over-claim the same conversion;
- customer lifetime value, repeat purchase and organic halo effects;
- currency fluctuation, payment terms and cash-flow timing.
A campaign that looks profitable in this tool may still be unprofitable for your business once those factors are included, and the reverse is equally true.
No guarantee of results
Nothing on this site is a promise or projection of earnings. Advertising performance depends on your offer, your market, your creative and factors outside anyone's control. Benchmark figures quoted in our articles are illustrative industry ranges, not targets you should expect to hit.
Accuracy and availability
We make a reasonable effort to keep the formulas correct and the content current, but we give no warranty of accuracy, completeness or availability. Content may become outdated without notice.
External links and advertising
This site displays third-party advertising and may link to external websites. We do not endorse, control or take responsibility for their content, claims, products or practices. Some links may be affiliate links; where that is the case, it does not change the price you pay or influence the calculator's output.
Limitation of liability
To the fullest extent permitted by law, the operator accepts no liability for any loss or damage — direct or indirect — arising from reliance on any content or result obtained from this site. Your use of the site is entirely at your own risk. See also our Terms of Service.
About the benchmark figures
The margin examples on the home page (80%, 40%, 20%) are illustrative round numbers chosen to show how break-even ROAS moves with margin. They are not researched industry averages, not targets, and not a claim about what your business should achieve. Use your own margin — it is the only one that matters to your break-even.
Affiliate and sponsored content
Advertising shown on this site is served by third parties and is not an endorsement. Some outbound links may earn a commission. Where that is the case it never changes the price you pay, never affects a calculated result, and never influences what the articles say.
Editorial independence
The formulas, the guidance and the FAQ are written independently of any advertiser. No advertiser reviews or approves content before publication, and no advertiser can have content changed or removed.
Found an error?
If a calculation looks wrong to you, please report it via the contact page with the exact figures you entered. Corrections to the maths are treated as urgent — a calculator that is quietly wrong is worse than no calculator at all.
