Terms of Use
Last updated: November 7, 2026
Please read these terms carefully. By using completecalculator.com, you agree to these Terms of Use. If you do not agree, please do not use the site.
1. Acceptance of These Terms
These Terms of Use govern your use of completecalculator.com, including all calculators, guides, blog articles, and other pages on the site. By accessing or using the site, you accept these terms in full. We may update these terms from time to time, and the updated version will be posted on this page with a new "Last updated" date. Your continued use of the site after an update means you accept the updated terms.
2. The Service
completecalculator.com provides 43 free online calculators covering finance, health, mathematics, date and time, and everyday practical calculations, together with explanatory guides and articles. The service is provided free of charge. You do not need to register, create an account, or pay to use any calculator on the site.
We aim to keep the site available at all times, but we do not guarantee uninterrupted access. The site may be unavailable for maintenance or updates, and we may change, add, or remove calculators, features, or content at any time without notice.
3. Accuracy Disclaimer: Results Are Estimates
Our calculators are built on standard, documented formulas and are tested against worked examples before publication. Even so, results are estimates, not exact figures, and they depend on the numbers and assumptions you enter.
Calculators on this site are provided for general information and educational purposes only. They are not professional advice, and they do not replace advice from a qualified professional. In particular:
- Financial calculators (including mortgage, loan, investment, tax, and retirement tools) are estimates only. They do not take account of your full financial situation, and they are not financial, investment, or tax advice. Check any important financial decision with a qualified financial adviser, accountant, or tax professional.
- Health calculators (including BMI, calorie, body fat, and pregnancy tools) are general guides only. They are not medical advice, diagnosis, or treatment, and they do not replace advice from a doctor or other qualified health professional.
- All other calculators are provided as practical aids. If a result will be used for a legal, safety, engineering, or other high-stakes decision, verify it independently and consult a qualified professional where needed.
4. Acceptable Use
You agree to use the site lawfully and responsibly. You must not:
- Use the site in any way that breaks the law, infringes the rights of others, or causes harm.
- Attempt to gain unauthorised access to the site, its servers, or any related systems, or to interfere with the site's operation, security, or availability.
- Use automated tools, bots, or scrapers to copy large amounts of content, overload the site, or collect data in bulk without our permission.
- Submit false, misleading, or harmful information through any form on the site, or impersonate another person or organisation.
- Use the site to send spam, distribute malware, or carry out any other abusive activity.
We may restrict or end your access to the site if we reasonably believe you have breached these terms.
5. Intellectual Property
The content on completecalculator.com — including its text, guides, calculator designs, layout, and branding — is owned by or licensed to the site, unless stated otherwise, and is protected by copyright and other intellectual property laws. You may use the calculators and read the guides for your own personal, non-commercial use.
You may share a link to a page on the site, and you may quote a short extract with clear attribution and a link back to the original page. You may not copy, republish, sell, or redistribute substantial parts of the site's content, or use it to build a competing service, without our prior written permission.
6. Third-Party Links and Advertising
The site may contain links to third-party websites, and it displays advertising, including through Google AdSense and other authorised advertising partners. Third-party sites and advertisements are not under our control, and we are not responsible for their content, products, or privacy practices. If you follow a link or click an advertisement, you do so at your own risk, and the third party's own terms and privacy policy will apply.
7. Privacy
Your use of the site is also governed by our Privacy Policy, which explains what information we collect, how we use it, and your rights. Please read it alongside these terms. You do not need to provide personal information to use the calculators, and we do not sell personal information to third parties.
8. Limitation of Liability
The site and its calculators are provided "as is" and "as available", without warranties of any kind, whether express or implied, including warranties of accuracy, completeness, fitness for a particular purpose, or non-infringement. To the fullest extent permitted by law, we will not be liable for any loss or damage arising from your use of, or inability to use, the site or its results — including direct, indirect, incidental, or consequential loss, and including any loss arising from a decision made on the basis of a calculator result.
Nothing in these terms limits any liability that cannot be limited by law, or any rights you have as a consumer that cannot be excluded.

We may update these Terms of Use at any time. Changes will be posted on this page with an updated "Last updated" date, and material changes will take effect from the date of posting. Please check this page periodically. If you continue to use the site after a change, you accept the updated terms.
