Terms of Use

Last updated 2026-05-31

These terms govern your use of SuperCalculator (the “Service”). By using the Service, you agree to them. If you disagree, do not use the Service.

1. What the Service is

SuperCalculator is a collection of free, browser-based calculators covering finance, investing, real estate, health, business, and career topics. Calculations run with public formulas and configurable assumptions. We do not store, broker, or transmit your financial, medical, or personal information beyond what is needed to render the page you requested.

2. Not professional advice

All output from the Service is for informational and educational purposes only. It is not — and is not intended to be — financial, investment, tax, legal, accounting, medical, nutritional, or any other form of professional advice. Examples:

Consult a qualified professional — licensed mortgage lender, CPA, physician, financial advisor, attorney — before making decisions based on any result you see here.

3. Accuracy

We work hard to make the math correct and the assumptions reasonable, but the Service is provided “as is”, with no warranty of accuracy, completeness, fitness for a particular purpose, or non-infringement. Tax brackets, interest rates, fee schedules, and default assumptions may be out of date. If you find a bug or disagree with an assumption, please tell us.

4. Acceptable use

You may use the Service for personal and commercial purposes, including embedding scenario URLs in articles, sharing them on social media, or referencing them in client work. You agree not to:

  • Scrape or otherwise place automated load on the Service in a way that degrades it for other users.
  • Abuse the /ask AI endpoint (it is rate-limited).
  • Misrepresent calculator output as our advice, endorsement, or recommendation.
  • Use the Service to violate any applicable law.

5. Intellectual property

The calculator math engine is intended to be open-source — see our contact page for the repository. The site brand, design, and content (including the long-form explainer pages) are © 2026 SuperCalculator, all rights reserved. You may quote short excerpts for review or commentary with attribution; you may not reproduce the full pages without permission.

6. AI features

Some features use large language models (currently Anthropic Claude) to route your questions to the right calculator and, in the future, to polish explanations. These models are inherently probabilistic and can be wrong. AI features never compute the underlying numbers themselves — those come from the deterministic calculation engine — but the AI’s choice of which calculator to use, or its framing of a result, may be incorrect. Treat AI output as a suggestion, not a fact.

7. Third-party services

The Service is hosted on Vercel, uses fonts from Google Fonts, and may call the Anthropic API for AI features. Each of those providers has its own terms. The Service does not embed third-party advertising or social-media trackers.

8. Limitation of liability

To the maximum extent permitted by law, neither SuperCalculator nor any contributor will be liable for any indirect, incidental, consequential, special, or punitive damages — or for any loss of profits, data, or savings — arising from your use of the Service. Our total liability for any direct damages is limited to USD $0 (the price you paid).

9. Changes

We may update these terms. Material changes will be noted at the top of this page with a new “Last updated” date. Continuing to use the Service after a change means you accept the new terms.

10. Governing law

These terms are governed by the laws of the jurisdiction in which the Service operator resides, without regard to conflict-of-law principles. Any dispute will be resolved in the courts of that jurisdiction.
