Terms of Use

Last updated November 13, 2026 · NoiMath

Acceptance

By using this site you agree to these terms. If you do not agree, do not use the site. These terms apply to every page, calculator and guide on the domain.

What the calculators are

The calculators are arithmetic tools. They apply the formulas documented on the methodology page to the numbers you enter. They do not verify inputs, they do not know anything about the property you are analysing, and they do not access third-party data about it.

No professional advice

Nothing on this site is financial, investment, legal, tax or accounting advice. No output should be relied on as a recommendation to buy, sell, finance, or refrain from any transaction. See the disclaimer for the full statement.

No warranty

The site is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose. The formulas are tested, but we do not warrant that the site will be uninterrupted or error-free, or that any output is accurate for your situation.

Limitation of liability

To the maximum extent permitted by law, the site operator is not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, data or opportunity, arising from your use of the site or reliance on any output.

Your responsibility

You are responsible for the inputs you enter and for how you use the results. A calculator cannot tell whether a rent is achievable, whether an expense is missing, or whether a property is a good purchase. Verify assumptions against leases, tax bills, insurance quotes and an inspection before relying on any number.

Licence to use the outputs

You may use the outputs of the calculators freely for your own analysis, including in commercial work such as an investment memo or a lender package. You may quote short excerpts of the text with attribution and a link. You may not republish substantial portions of the site's text, guides or design as your own.

Acceptable use

You may not scrape the site at a volume that degrades service, attempt to disrupt or gain unauthorised access to it, republish its content as your own, or use it in a way that violates applicable law. Automated access that respects the site's published rules and rate is permitted.

Third-party links and advertising

Pages may contain links to third-party sites and display advertising. Those sites and ads are not controlled by this site, and their content, products and privacy practices are their own responsibility. An advertisement is not an endorsement, and no advertiser has influence over a formula or a result.

Availability and changes

Pages, calculators and formulas may change or be removed without notice. Material changes to these terms are reflected in the date above. Continued use of the site after a change means the updated terms apply.

Severability

If any provision of these terms is found unenforceable, the remaining provisions stay in effect and the unenforceable provision is limited to the minimum extent necessary.
