The plain-English terms

Last updated: 30 June 2026.

What we provide

OnlyCalculators offers free online calculators and accompanying explanations for general information and educational purposes. Each tool is built from a stated formula or method and is intended to help you estimate and understand a result, not to make a decision for you.

Not professional advice

Our calculators and content are not a substitute for professional advice. Nothing on this site is medical, financial, tax, legal, engineering, or other professional advice, and no professional relationship is created by using it. Results are estimates that can depend on assumptions, rounding, current rates, and the accuracy of the values you enter. Before you act on anything that affects your health, money, safety, or legal position, confirm it with a qualified professional and the current official source.

No warranty

We work hard to keep every calculator accurate and to cite reputable sources, but the site is provided "as is" and "as available", without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability. Formulas can be simplified, official figures change, and errors can occur.

Limitation of liability

To the fullest extent permitted by law, OnlyCalculators and its contributors are not liable for any loss or damage arising from your use of, or reliance on, the calculators or content, including any decision made based on a result. Your sole remedy if you are dissatisfied is to stop using the site.

Acceptable use

You may use OnlyCalculators for lawful personal and commercial purposes and may embed our widgets where we provide an embed option. Please do not misuse the site, for example by attempting to disrupt it, scrape it at a scale that degrades service for others, remove attribution from embeds, or present our content as your own.

Intellectual property

The site design, text, and original explanations are ours or our contributors'. Formulas and underlying facts are not owned by anyone, and we cite the standards and references we rely on. You are welcome to use a calculated result; you may not wholesale copy our written explanations without permission.

Advertising and third-party links

This site is supported by ads served through Adsterra and may link to third-party websites, including the sources behind each calculator. We are not responsible for the content, products, or privacy practices of third parties. See our Privacy Policy for how advertising data is handled.

Changes

We may update these terms as the site evolves. Continued use after a change means you accept the updated terms. The "last updated" date above shows the current version.
