Terms of use
PureCalc is free to use. By using it you agree to these terms. Please read the disclaimer too: results are estimates, not professional advice.
Last updated October 5, 2026.
Using the site
You may use the calculators for personal and business purposes and share links to any page. Do not try to disrupt the site, overload it, or get around its security.
Estimates, not advice
Every result is an estimate based on the inputs you give and the published sources each calculator cites. Results are not financial, tax, legal, medical, engineering or other professional advice. See the disclaimer for details.
No warranty
We work hard to keep every calculator correct and tested, but the site is provided as is, without any warranty that it is accurate, complete or always available.
Limitation of liability
To the extent the law allows, PureCalc is not liable for any loss or damage that comes from using the site or relying on its results.
Content
The site's text, design and code belong to PureCalc. The formulas and reference data come from the public sources cited on each page.
Changes
We may update these terms. The new version is posted here with a new date at the top, and using the site after that means you accept it.
