Disclaimer

Results are estimates

Every calculator on this site produces an estimate based on the formula and assumptions stated on its page. Real-world outcomes depend on factors no general-purpose tool can capture: fees, taxes, changing rates, individual health, local rules, and rounding conventions used by specific institutions.

Not professional advice

Nothing on this site constitutes, or substitutes for:

• Financial advice — loan quotes, investment decisions, tax calculations, or retirement planning should be confirmed with a licensed professional or the relevant institution.
• Medical advice — health calculators use population-average formulas and are not a diagnosis or treatment guidance. Consult a qualified health professional.
• Legal advice — date and deadline calculations may not match the counting rules of your jurisdiction or contract.

No warranty

The site is provided “as is.” While formulas are tested and pages are reviewed regularly, we make no warranty that results are error-free or suitable for any particular purpose. Use of the site and its results is at your own judgment and risk.

External links

Pages may link to external sources (for example, standards bodies) for reference. We're not responsible for the content of external sites.

Found an error?

If a result looks wrong, tell us through the “Report an error” link on the calculator's page. We investigate every report against the cited formula.
