Terms of Use

By using CalcNests, you agree to these Terms of Use. If you don't agree with them, please don't use the site.

CalcNests provides free calculators and reference tools for personal, informational use. You may use the site and its calculators for any lawful purpose. You agree not to misuse the site — for example, by attempting to disrupt it, scrape it at a disruptive scale, or use it in a way that could damage, disable, or impair it for other users.

Every calculator on CalcNests is built on a standard, correct formula, but results are estimates based on the inputs and assumptions you and the calculator use — they are not guarantees, official government figures, or professional advice. See our Disclaimer for more detail, particularly for financial calculators.

You're responsible for how you use the information a calculator gives you. For decisions with real financial, legal, tax, or medical consequences, verify important numbers with a qualified professional or an official source before relying on them.

The CalcNests name, design, and site content (including calculator explanations, FAQs, and layout) belong to CalcNests unless otherwise noted. You may link to CalcNests pages freely. You may not copy, republish, or redistribute substantial parts of the site's content without permission.

CalcNests may link to third-party websites for reference or context. We don't control those sites and aren't responsible for their content, accuracy, or privacy practices. Links don't imply an endorsement.

We aim to keep CalcNests available and working correctly, but we don't guarantee uninterrupted access. The site may be unavailable at times for maintenance, technical issues, or reasons outside our control.

CalcNests is provided “as is,” without warranties of any kind, express or implied. To the fullest extent permitted by law, CalcNests and its operators are not liable for any damages or losses arising from your use of the site or reliance on its calculators, including decisions made based on calculator results.

We may update these Terms of Use from time to time. The “Last updated” date at the top of this page reflects the most recent revision. Continued use of the site after a change means you accept the updated terms.
