ROAS calculator terms and permitted use
Effective August 17, 2026, these terms govern the calculators, formulas, examples, guides, and supporting pages at roascalculator.org. You may use the site for lawful personal or business planning and may cite or share results when you preserve the input definitions and identify them as estimates.
Do not attempt to disrupt the service, bypass security controls, submit harmful code, scrape the site in a way that degrades availability, or misrepresent the project as affiliated with an advertising platform.
Planning estimates, not financial advice
The calculators perform mathematical relationships using user-supplied inputs. They do not provide accounting, investment, legal, tax, or financial advice and do not guarantee revenue, profit, bidding outcomes, attribution accuracy, or campaign performance.
You are responsible for verifying source data, currency, period, attribution model, tax treatment, cost scope, and the suitability of any decision. Material business decisions should be reviewed against accounting records and qualified advice.
Availability and accuracy
We aim to keep formulas transparent and correct, but the service is provided as available without a promise of uninterrupted access or fitness for a particular purpose. Features may change when calculation methods, platform conventions, or technical requirements change.
Report suspected errors with reproducible anonymous inputs. Until an issue is resolved, compare the result with the published formula or an independent calculation.
Content, trademarks, and external services
Original interface code and site content are protected by applicable rights. Google, Meta, TikTok, Amazon, Shopify, and other names belong to their respective owners and are used only to identify common advertising contexts.
Links to third parties do not create endorsement or control. Third-party content, availability, terms, and privacy practices remain their responsibility.
Changes and contact
Continued use after published changes means the updated terms apply from their effective date. Questions can be sent to legal@roascalculator.org. Last reviewed August 17, 2026.
