Terms of Service
Last updated: May 5, 2026
Acceptance
Using MathLab — opening a calculator, copying a result, or following an embed — is acceptance of these terms. They are written to be specific to what MathLab actually is: a collection of small, browser-based calculators that return numeric results based on the formulas published alongside each tool. If a section below is materially updated, the “last updated” date at the top of the page reflects the change.
What MathLab is, and what it is not
MathLab is a reference utility. The mortgage, loan, IRA, GPA, tip, percentage, sales-tax, snow-day, and related calculators are designed for general estimation and learning. They are not a substitute for a licensed financial advisor, a CPA, a mortgage broker, a school registrar, a tax preparer, or any state or federal authority. Results are calculated against the formulas and rate tables published on each tool’s page; a tax-year transition or rate change between visits can change the answer.
Use of the site
You may use MathLab for any lawful personal or professional reference. Treat the calculators as you would treat a spreadsheet you wrote yourself: verify edge cases before acting on a large financial decision. Do not attempt to disrupt the site, gain unauthorized access to its underlying systems, or scrape the pages at a rate that affects availability for other visitors. Embedding short calculator screenshots in editorial content is permitted with attribution.
Disclaimer of warranties
MathLab is provided on an as-is and as-available basis. The publisher does not warrant that any calculator output is fit for a specific purpose, that the rate tables are current to the minute, or that the formulas cover every regional variant. Where the result of a calculation matters financially or legally, confirm the answer with the primary source the calculator cites or with a qualified professional.
Limitation of liability
To the maximum extent permitted by law, the publisher is not liable for indirect, incidental, special, or consequential damages arising from use of MathLab, including losses tied to financial decisions made on the basis of a calculator result. These terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-laws principles.
