Terms of use

Last updated: 18 August 2026

By using onecalculate.com, you agree to these terms. If you don't agree, please don't use the site.

The service

OneCalculate provides free, self-service calculators and related informational content. The site is provided "as is." We work to keep every rate current and every formula correct (see ourmethodology), but we don't guarantee the site is error-free, uninterrupted, or fit for any particular purpose.

Not advice

Nothing on this site is financial, legal, tax or professional advice, and using a calculator doesn't create an advice or client relationship between you and OneCalculate or Nirbhay Tripathi. See ourdisclaimer for the full detail.

Acceptable use

You agree not to:

• Use automated tools to scrape or overload the site beyond normal personal use
• Reproduce the site's content, formulas, or design at scale without permission
• Use the site for any unlawful purpose

Sharing a calculator's embed widget or a share link with your own inputs encoded is expected and welcome — that's what those features are for.

Intellectual property

The site's design, code, written content and OneCalculate branding are owned by OneCalculate. The underlying rates and formulas we calculate with are drawn from public official sources, credited on each page.

Limitation of liability

To the maximum extent permitted by law, OneCalculate and Nirbhay Tripathi are not liable for any loss or damage arising from your use of, or reliance on, this site or its calculators, including decisions made using a calculator's output.

Changes

We may update these terms as the site grows. Continued use after a change means you accept the update.
