These Terms and Conditions (“Terms”) apply to your use of allcalculator.biz (“All Calculator”, “the site”, “we”, “us” or “our”). By using the site, you agree to these Terms. If you do not agree, please do not use the site.
Using the Site
All Calculator provides free online calculators, converters and guides for general information and education. You do not need an account to use them.
You may use the site for personal, educational and business purposes, including using results in your own work, homework, reports and planning.
Accuracy of Results
We build and test every calculator carefully. We work the examples on each page by hand and check them against the calculator before publishing. Even so:
- results depend on the numbers you enter, so check your inputs,
- results are rounded for display, so small differences can appear,
- formulas and estimates have limits, which we explain on the relevant pages, and
- rules, rates and guidance, such as tax rates, can change after a page was last checked.
The calculators and guides are provided “as is” and “as available”. We do not promise that they are free of errors, complete, or suitable for any particular purpose. For anything important, check the result another way or ask a qualified professional.
If you find an error, please tell us through our contact page. We review every report and correct confirmed errors.
Health Calculators
Health and fitness calculators, such as the BMI and calorie calculators, give general estimates based on published formulas. They are not medical advice, a diagnosis or a treatment plan, and they cannot take your full health history into account. Always speak to a doctor or another qualified health professional before making decisions about your health, diet or exercise. Do not delay or ignore professional advice because of a result on this site.
Financial, Tax and Business Calculators
Money, tax, loan, pricing and business calculators give estimates for planning and education. They are not financial, tax, legal or investment advice. Real figures from lenders, tax authorities and other organizations may differ because of fees, rounding, local rules and changes over time. Check important figures with a qualified adviser or the organization involved before you rely on them.
Acceptable Use
When using the site, you agree not to:
- copy, scrape or download the site’s content or calculators in bulk, or use automated tools that place an unreasonable load on the site,
- try to access parts of the site or its systems that are not meant to be public,
- interfere with the site’s security, advertising or normal operation,
- use the site for anything unlawful, or
- click on ads dishonestly or encourage others to, which breaks Google’s advertising rules.
We may block access for anyone who breaks these rules.
Intellectual Property
The site’s text, guides, calculator designs, code, layout and logo belong to All Calculator or are used with permission, and are protected by copyright and other laws.
You may:
- use results from the calculators however you wish,
- share links to any page on the site, and
- quote short extracts from our guides with a link back to the page.
You may not copy whole pages, republish our guides or calculators on another website, or present our work as your own without written permission. Formulas and mathematical facts belong to no one, and you are free to use them.
Embedding and Links
You are welcome to link to any page on All Calculator. Please do not frame the site inside another website, or embed our calculators on your own site, without asking us first.
Our pages may link to other websites, such as official sources. We do not control those sites and are not responsible for their content or their privacy practices.
Advertising
The site is funded by advertising, including ads served by Google. Ads are provided by third parties, and we do not endorse the products or services they advertise. How advertising uses cookies is explained in our Privacy Policy.
Limitation of Liability
As far as the law allows, All Calculator and the people who run it are not liable for any loss or damage that comes from using, or being unable to use, the site, or from relying on any result, guide or information on it. This includes loss of money, profit, data or opportunity, and indirect or consequential loss.
Nothing in these Terms limits or excludes any liability that cannot be limited or excluded by law. That includes liability for death or personal injury caused by negligence, liability for fraud, and any rights you have as a consumer that the law does not allow us to remove.
Changes to the Site and These Terms
We may change, add or remove calculators and pages, or pause the site, at any time. We may also update these Terms. The effective date at the top shows when they were last changed. If you keep using the site after a change, the updated Terms apply.
Governing Law
These Terms are governed by the laws that apply to the operator of All Calculator. If you live in a country whose consumer laws give you extra rights, or the right to bring a claim in your local courts, nothing in these Terms takes those rights away.
