The service
The site provides free percentage calculators and related articles for personal and educational use. We may change, add, or withdraw tools or content at any time. We do not charge for the calculators themselves. Advertising may appear on pages; it is provided by third parties and is not a recommendation of any product.
No professional advice
Results and explanations are for general information. They are not financial, tax, legal, medical, or academic advice. You are responsible for checking that a calculation is appropriate for your situation, especially where money, grades, or official records are involved.
Accuracy
We take care to use standard formulas and to avoid misleading outputs such as Infinity or NaN. Even so, we do not warrant that every result will be error-free or suitable for a particular use. You should review the working on the page and, where it matters, confirm the result independently. See also our Disclaimer and calculation methodology pages.
Acceptable use
You may not misuse the site, attempt to disrupt it, scrape it in a way that harms service for others, or use it to build a competing service by wholesale copying of our text. You may link to our pages.
Intellectual property
The site’s layout, original explanations, and branding are provided by Real Percentage Calculator. Formulas themselves are standard mathematics and are not claimed as exclusive property.
Third-party services
The site may load advertising, analytics, and hosting-related services, as described in the Privacy Policy. Their terms also apply when those services run.
Limitation of liability
To the extent permitted by law, Real Percentage Calculator is not liable for any loss or damage arising from your use of the site or reliance on a calculation, including indirect or consequential loss. Nothing in these terms excludes liability that cannot legally be excluded.
Changes
We may update these terms from time to time. The date at the top of this page will change when we do. Continued use of the site after an update means you accept the revised terms.
