Terms of Service
These terms govern your use of CalcKit, a free collection of 280 online calculators provided as-is for educational and personal use. By using the site you accept that all tools and content are offered without warranty of any kind, express or implied. Calculator results are estimates for informational purposes. Health calculators are screening tools, not medical advice — consult a healthcare professional for diagnosis or treatment decisions. Financial calculators project scenarios from the inputs you provide and do not constitute financial, tax, or legal advice; actual loan terms, taxes, and investment returns vary. We work to keep every formula accurate and document the method each calculator uses on its page, but you should verify important numbers independently. We may update these terms at any time; continued use of the site constitutes acceptance of the current version.
