Disclaimer
Last updated: November 2026
Educational purpose
All calculators, tables, quizzes and guides on MathKit are free, provided for informational and educational purposes only, and require no account. They are not a substitute for professional advice or your own verification of anything that matters.
No professional advice
Financial results (loan payments, interest, margins, discounts) are estimates that do not account for taxes, fees, insurance, or the terms of any real product. Statistics tools use standard conventions — for example population variance — that may differ from what a particular textbook or course expects. Unit conversions use fixed factors and round only for display. Health-adjacent and engineering calculations must be confirmed with qualified professionals. Nothing on this site is financial, medical, legal, or engineering advice.
Accuracy
Every calculator ships as pure, unit-tested logic checked against known-correct cases, and the site's test suite runs on every deploy. Input rules are enforced at the field level — nonexistent shapes, over-100% discounts, and reversed date ranges produce an explicit error rather than a misleading number. Even so, rounding, keyboard slips, or undiscovered bugs can affect a result: if a number will influence an important decision, verify it independently, andtell usabout anything that looks wrong — reports with exact inputs are examined first.
Advertising and third-party scripts
The site is free because it carries advertising. Third-party providers, including Monetag (in-page push), Adsterra (banner/native placements), and Google Analytics, may set their own cookies or use device identifiers for the purposes described in ourprivacy policy. Your calculations are processed entirely in your browser and are never part of that traffic.
External links and trademarks
Links to third-party sites are provided for convenience; we are not responsible for their content or practices. Any brand or product names mentioned in examples or service disclosures belong to their respective owners and do not imply endorsement.
Changes
This disclaimer is updated when site behavior changes in a way you should know about. The "last updated" date above reflects the most recent revision.
