4. Liability for content

Most calculators use published formulas, which we check against reference examples. Even so, the results are estimates and are not financial, medical, legal or any other professional advice. Some health calculators are simplified educational models and say so in a visible warning. The website is provided "as is"; see sections 2, 3 and 9 of the Terms of Use for details. If you find an error, please let us know and we will fix the calculator and its description.

You may embed our calculators on your website free of charge under section 6 of the Terms of Use.
