Terms of Use

Using the calculators

RK Calculator is free to use for personal and business purposes. The calculators are tested and reviewed carefully, but every result depends on the values entered and on each calculator's stated assumptions and limitations, which are shown on its page.

Not professional advice

Results and explanations are for information. They are not financial, legal, medical, engineering or other professional advice. For decisions that matter, such as a loan, a structural pour or a medical question, check the result with a qualified professional.

Accuracy and liability

We work to keep every calculator correct and fix reported errors promptly (see how to report an error). The site is provided as it is, and [limitation-of-liability wording for the operator's jurisdiction: to be provided by the site owner].

Content and code

The explanations, diagrams and software on this site are original work. You may link to any page and quote short passages with a link back. Embedding calculators on other sites will be offered through official widgets with their own terms.

Acceptable use

Please don't attempt to disrupt the site, overload it with automated requests, or copy it wholesale.
