By using this site you agree to these terms. If you do not agree, please do not use the site.
This site provides free online calculators and accompanying explanatory material. No registration or payment is required, and no contract for services is formed by using it.
All results and written content are provided for general information only. They do not constitute medical, legal, financial, tax, or any other professional advice, and no professional relationship is created by your use of this site.
Calculations rely on general formulas and on assumptions stated on each page. Individual circumstances vary, and formulas that describe populations well can describe a particular person poorly.
The site is provided "as is". While reasonable care is taken to ensure calculations are correct and content is current, no warranty is given as to accuracy, completeness, or fitness for any particular purpose. Formulas, rates, and regulations change, and content may become outdated.
To the fullest extent permitted by law, the operator accepts no liability for any loss or damage arising from use of, or reliance on, this site — including decisions made on the basis of any calculation shown here. You use these tools at your own risk.
The explanatory content, calculator implementations, and design of this site are the property of the operator.
You may read, print, and share links freely, and quote short extracts with attribution. You may not reproduce substantial portions of the content, republish it commercially, extract the calculator code for use elsewhere, or scrape the site by automated means, without prior written permission.
You agree not to interfere with the operation of the site, attempt to gain unauthorised access, place unreasonable load on the hosting infrastructure, or use the site for any unlawful purpose.
The site carries third-party advertising. The operator does not control and does not endorse the products or services advertised, and is not a party to any transaction between you and an advertiser.
Links to other sites are provided for convenience. The operator has no control over their content and accepts no responsibility for it. A link is not an endorsement.
The site may be modified, suspended, or withdrawn at any time without notice. Tools may be added, changed, or removed, and formulas may be updated as standards change.
If any provision of these terms is found unenforceable, the remaining provisions continue in full effect.
