What We Provide
We provide free calculators and educational guides about proportions, ratios and statistics. All calculators run in your browser, no account is needed, and the tools are provided “as is”, without any warranty of any kind. We aim for accuracy — see our Methodology page — but we do not guarantee that any result is error-free or suitable for a particular purpose.

You may not use the site to break the law, to attempt to access systems you are not authorised to access, to overload the site, or to copy the site’s content and present it as your own. You may link to our pages and quote short excerpts with attribution.
No Professional Advice
Our content is educational. It is not professional, medical, legal or financial advice. Decisions that affect health, safety, money or legal rights should be checked with a qualified professional, and statistical results should be interpreted with the conditions and limits stated on each tool page.
Limitation of Liability
To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of the site or from reliance on its results, including errors in a calculation or in a guide. Your use of the site is at your own risk.
