Informational utility
ROAS Calculator provides arithmetic tools and general explanations for return on ad spend, contribution break-even, contribution return, cost per action, and paid-media customer acquisition cost. The site does not provide accounting, tax, legal, investment, or individualized financial advice.
Your inputs and decisions
You are responsible for the accuracy, consistency, and relevance of the values you enter. Use the same currency, reporting period, conversion event, attribution window, and attribution model when comparing campaigns. Review which costs are included in your margin before relying on a break-even result.
Platform-attributed revenue may differ from incremental revenue caused by advertising. The calculator does not verify attribution, remove duplicated credit across platforms, or test causality.
No performance guarantee
Outputs are mathematical estimates derived from the values you enter. They do not guarantee profit, growth, savings, bidding outcomes, future revenue, campaign performance, or business results. A result above entered contribution break-even does not prove total business profitability because fixed and unentered costs may still apply.
Availability and changes
The site is provided without a promise of uninterrupted availability. Features, formulas, explanations, and these terms may be updated to improve accuracy, clarity, security, or compatibility. Material methodology changes will be reflected on the Methodology page.
External sources
External links are provided for source transparency and further reading. ROAS Calculator does not control external content or availability, and a link does not create an affiliation, partnership, endorsement, or warranty.
Permitted use
You may use the calculator for lawful personal or business analysis. Do not interfere with the site's operation, attempt to introduce malicious code, misuse the service to violate another person's rights, or misrepresent the site's independent status.
Liability boundary
To the extent permitted by applicable law, the site is provided on an “as available” basis without warranties about suitability for a particular decision. You remain responsible for reviewing material business decisions with appropriately qualified professionals and your own complete records.
