Terms of Use

Last updated 24 July 2026

What this site is

CalcStocks provides free educational calculators for investing and company valuation. Each tool performs arithmetic on figures you supply and displays the result together with the method used.

Not investment advice

Nothing on this site is investment, financial, tax or legal advice, and nothing here is a recommendation to buy, sell or hold any security.

Outputs are the arithmetic consequence of assumptions you choose. They are not forecasts, price targets or valuations of any actual company, and they do not take account of your circumstances, objectives or risk tolerance.

Consider consulting a qualified financial professional before acting on anything you calculate here.

No warranty

The site is provided as is, without warranty of any kind. We take accuracy seriously and document our conventions, but we cannot warrant that every figure is free of error or fit for your particular purpose. Verify anything that matters independently before relying on it.

If you believe a calculation is wrong, please tell us through the contact form — corrections are welcome and acted on.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any loss or damage arising from use of this site or reliance on its output, including investment losses.

Acceptable use

You may use these calculators freely for personal and professional purposes. Do not attempt to disrupt the service, submit automated bulk requests to the contact endpoint, or misrepresent output as originating from a regulated advisory service.

Changes

We may update these terms as the site develops. The date at the top of this page always reflects the current version.
