Terms of Use
Last updated: July 3, 2026. By using calcperch.com you agree to these terms — they're short and written to be read.
What CalcPerch is
CalcPerch provides free online calculators, converters, generators, and related guides. Tools run in your browser — the one exception, the URL shortener, is described in the privacy policy. Use of the site requires no account and no payment.
For information only — not professional advice
Our calculators and articles are for general information and education. They are not financial, tax, legal, medical, or other professional advice. Results are estimates based on the inputs you provide and simplified models of the real world (tax rules, interest calculations, health metrics, and prices change and vary by situation). Before making decisions that matter — loans, taxes, health, business spending — verify the numbers with a qualified professional or the primary source.
No warranty
The site and its tools are provided "as is" and "as available." We work hard on accuracy and test our calculators against reference values, but we cannot guarantee that every result is correct, complete, or current, or that the site will be uninterrupted or error-free. To the fullest extent permitted by law, CalcPerch is not liable for any loss or damage arising from your use of, or reliance on, the site or its results.
Acceptable use
You may use the tools freely for personal and commercial purposes. You agree not to: attempt to disrupt or overload the site; scrape or bulk-download content for republication; use our tools or content to mislead others; or attempt to circumvent any technical or security measure. Automated fair use (e.g., occasionally linking a short URL) is fine; bulk automated abuse is not.
Intellectual property
The site's content — text, guides, design, and code we authored — belongs to CalcPerch. You're welcome to link to any page and to quote brief excerpts with attribution and a link. Republishing whole pages or articles is not permitted without permission.
Third-party links and services
Some pages link to external websites or rely on third-party services (for example, our URL shortener falls back to established shortening providers). We don't control external sites and are not responsible for their content or practices.
Advertising
CalcPerch is free to use and supported by advertising. Ads are provided by third-party networks (such as Google AdSense) and never influence the results our calculators produce. See our Privacy Policy for how advertising cookies work.
Changes to these terms
We may update these terms as the site evolves. The "last updated" date above always reflects the current version, and continued use of the site after a change means you accept the updated terms.
