Terms of Use

Last updated October 19, 2026

Using the calculators

Calcamaze provides free calculators and explanatory articles for general information and education. By using the site you agree to these terms. If you do not agree, please do not use the site.

Not professional advice

Results are estimates based on the information you enter and on standard formulas and typical values. They are not financial, tax, investment, legal, medical, nutritional, engineering, structural or other professional advice, and they do not create a professional relationship. Always check important results independently and consult a qualified professional before acting on them — especially for decisions involving money, health, building work or safety.

Accuracy

We work hard to keep the calculators correct: every calculator is tested, and some are additionally reviewed by a named person, as shown on the page. Even so, we cannot guarantee that every result, article or figure is complete, accurate or up to date, or suitable for your circumstances. Local rules (such as building codes, tax rates and lending rules) vary and change.

No warranty and limitation of liability

The site is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose. To the fullest extent permitted by law, Calcamaze is not liable for any loss or damage arising from your use of, or reliance on, the site or its results. Nothing in these terms limits liability that cannot be limited by law, or your rights as a consumer under the laws of your country.

Acceptable use

Please do not attempt to disrupt the site, access it in ways that place an unreasonable load on it, or copy large parts of its content to republish elsewhere. You are welcome to link to any page and to share calculation links.

Content

The site’s text, design and code are owned by Calcamaze. Formulas and facts themselves are not owned by anyone; you may use the results of your calculations freely.

Changes and contact

We may update these terms; the date above shows the latest version. Questions: postmaster@calcamaze.com.
