Acceptance of these terms
By accessing or using Calculator Matters at calculatormatters.com (the "Site"), you agree to be bound by these Terms of Use and by our Privacy Policy and Disclaimer. If you do not agree with any part of these terms, please do not use the Site.
Who can use the site
The Site is intended for general audiences. You may use the calculators and content for any lawful purpose — personal, educational or professional. What is not permitted is copying, scraping, framing or republishing the Site or substantial parts of it, except as these terms allow for embeds and the API. By using the Site, you confirm that you are able to form a binding agreement in your jurisdiction.
Permitted use
Calculator Matters provides formula-backed online calculators and related educational content. You may use the Site provided that you:
- Do not use the Site for any unlawful purpose or in violation of these terms.
- Do not reverse engineer, bulk-scrape, or reproduce the Site or its functionality without permission — see Embedding our calculators for the licensed exceptions.
- Do not interfere with the proper working of the Site, including by introducing malicious code or placing unreasonable load on our servers.
- Do not present our calculators or content as your own.
Embedding our calculators
Our official embed widgets — the responsive iframes generated from any calculator's /embed/ URL, as described on the Embed a Calculator page — are one licensed exception to the reproduction restrictions in these terms. You may add any Calculator Matters tool to your own website, blog, or intranet this way, free of charge, on personal or commercial sites alike, provided that the small "Powered by Calculator Matters" attribution credit stays visible and intact and you do not modify, strip, or misrepresent the embedded tool. This permission covers only the official embed widget; it does not extend to copying our page content, scraping the Site, or reproducing a calculator's logic outside the provided iframe. The public JSON API described on the developers page is the other: you may call it from personal or commercial apps as that page sets out.
Intellectual property and copyright
All content on the Site — text, the presentation of formulas, explanations, code, design, graphics and logos — is owned by the operator or used under licence, and is protected by applicable intellectual property laws. You are welcome to link to individual pages. Brief quotation with clear attribution and a link back is generally welcome; you may not republish or redistribute substantial portions of our content without prior written permission, except through the official embed widgets described above. For content ownership detail and how to report or counter a copyright claim, see our Copyright & DMCA Policy.
No professional advice
The calculations and information on this Site are for general informational and educational purposes only. They do not constitute financial, investment, medical, legal, tax, or any other professional advice. Please read our full Disclaimer before relying on any result.
Accuracy and availability
We work to keep the calculators accurate and current, but we do not warrant that the Site will be error-free, uninterrupted, or free of outdated information. We may modify, suspend, or discontinue any part of the Site at any time without notice.
Third-party advertising and links
The Site may display advertising and may link to third-party websites. Those third parties operate under their own terms and privacy policies, and we are not responsible for their content or practices. See our Advertising Disclosure and learn about our use of cookies for detail.
Limitation of liability
To the fullest extent permitted by law, Calculator Matters and its operators shall not be liable for any direct, indirect, incidental, consequential, or exemplary damages arising from your use of the Site or your reliance on its content or calculations.
Indemnity
You agree to hold Calculator Matters and its operators harmless from any claim or demand arising out of your misuse of the Site, your violation of these terms, or your infringement of the rights of another party.
Downloadable files and workbooks
Some calculators let you download a spreadsheet (XLSX) or CSV generated from the values you enter. These files are provided for your own personal or internal use as educational estimates. You may not resell or redistribute them as a standalone product, and — like the on-page results — they are not professional advice and come with no warranty of accuracy.
Your feedback
If you send us feedback, a correction, or a suggestion, you grant us permission to use it to improve the Site without obligation or compensation to you. Please do not send confidential information you do not want us to use for that purpose.
Governing law and disputes
These terms are governed by the laws of India. Any dispute arising from these terms or your use of the Site is subject to the courts having jurisdiction over Udham Singh Nagar district, Uttarakhand, India, without prejudice to any mandatory consumer-protection rights you have under the law of your own country of residence.
Severability, waiver, and entire agreement
If any provision of these terms is found unenforceable, the remaining provisions continue in full force. Our failure to enforce a provision is not a waiver of it. Together with our Privacy Policy, Disclaimer, and related policies linked here, these terms are the entire agreement between you and us regarding your use of the Site.

Terms FAQ
Can I use the calculators for personal use?
Yes. You may use the calculators for any lawful purpose — personal, educational or professional — and they run directly in your browser.
Can I republish or embed your calculators or content?
You may not bulk-copy, scrape, mirror, or republish substantial portions of the Site or pass our calculators or content off as your own without prior written permission. One licensed exception is our official embed widgets: you may add any calculator to your own website, blog, or intranet — personal or commercial — for free, using the iframe snippet from the Embed a Calculator page, as long as the “Powered by Calculator Matters” attribution stays visible and intact. The public API described on the developers page is the other.
Can I use the downloadable Excel/CSV files for my own work?
Yes — the workbooks and exports are generated from your inputs for your own personal or internal use. You may not resell or redistribute them as a product, and they remain educational estimates, not professional advice.
Do you guarantee the results?
No. The Site and its results are provided on an “as-is” basis without warranties. Results are educational estimates — verify anything important with a qualified professional, as set out in the Disclaimer.
