Terms of use

Toolora is provided free of charge for personal and commercial use. You may use the results in your own work without attribution. You may not present the site itself as your own, or scrape it to republish the tools elsewhere.

The calculations use standard, published formulas and are covered by automated tests, but no guarantee of accuracy is given for any particular purpose. Each tool shows the formula it uses so you can verify it. Check anything that matters before relying on it.

Financial, academic, medical and engineering results are informational only. They are not financial advice, not a grade guarantee, and not a substitute for a qualified professional or for a design review. Decisions with real consequences deserve a second source.

The site is provided “as is”, without warranty of any kind. It may be unavailable, changed or withdrawn at any time. To the fullest extent permitted by law, we are not liable for any loss arising from use of the site or reliance on its results.
