What CalcHub is

CalcHub provides free online calculators for general informational and educational purposes. Every calculation runs in your browser; we operate no accounts and store none of your inputs.

Not professional advice

Our calculators are not financial, tax, legal, or medical advice, and they do not create a professional relationship of any kind. Results are estimates based on the numbers you enter and the assumptions stated on each page. For decisions that matter — a mortgage, a tax filing, a medical question — consult a qualified professional.

Acceptable use

You may use the calculators for personal and commercial planning. You may link to any page and share calculation links freely. You may not misrepresent CalcHub's outputs as professional advice, attempt to disrupt the service, or scrape the site at a rate that degrades it for others.

No warranty

The calculators are provided "as is", without warranties of any kind. While we verify our formulas against documented standards, we do not guarantee that results are error-free or suitable for any particular purpose. To the maximum extent permitted by law, CalcHub is not liable for decisions made based on its outputs.

Intellectual property

The CalcHub name, design, and original content are ours. The mathematical formulas themselves are public knowledge and free for anyone to use.

Changes

We may update these terms as the site evolves; the "last updated" date above will reflect the latest version. Continued use after changes means you accept them.
