Terms of use

Answerivo provides free, informational calculators. Each one performs arithmetic on the values you supply and displays the result along with the formula used. Nothing on this site constitutes accounting, tax, legal, financial, investment, veterinary, engineering, or professional advice of any kind.

We work to keep the formulas correct and to document our assumptions, but results depend entirely on the inputs you provide and on assumptions that may not fit your situation. You are responsible for verifying any figure before relying on it for a bid, a purchase, a payroll run, a loan application, or any other decision.

If you find a result you believe is wrong, please report it — corrections are a priority.

You may use Answerivo for personal and commercial purposes, including in your own business workflow. You may not scrape the site at a volume that degrades service, attempt to circumvent security measures, republish the site’s content as your own, or present Answerivo output as certified or professionally reviewed.

The site’s design, written explanations, and calculator implementations belong to Answerivo. The underlying mathematical formulas are general knowledge and free for anyone to use.

The site is provided as-is and as-available. We may add, change, or remove calculators at any time, and we do not guarantee uninterrupted access.

To the maximum extent permitted by law, Answerivo is not liable for any loss or damage — including lost profit, mispriced work, or business decisions — arising from your use of the site or reliance on its output.

These terms may be updated as the site develops. Continued use after an update means you accept the revised terms.
