Terms of Use

Last updated: 2026-08-31

Use of the site

Stockcalculator.io is free to use for any lawful purpose, personal or commercial. Don't abuse the service (automated scraping at disruptive volume, attempts to breach the infrastructure) and don't misrepresent its output as ours where you've modified it.

Not investment advice

Everything on this site is educational. The calculators perform arithmetic on numbers you supply; nothing is a recommendation, solicitation, or offer to buy or sell any security or other asset, and nothing is personalized to your circumstances. Worked examples are historical scenarios. The tax field applies a single illustrative rate and is not tax advice. For decisions with real consequences, consult a licensed professional.

Accuracy and reliance

We work hard on correctness — the methodology page describes the exact-arithmetic engines, the average-cost method, and the test suite — but the site is provided "as is," without warranties of any kind. Verify independently before relying on any figure.

Content

Articles and other written content are © Stock Calculator. You may quote reasonable excerpts with attribution and a link. Cited research remains the property of its publishers and is linked at the source.

Liability

To the maximum extent permitted by law, we are not liable for any damages arising from use of, or inability to use, this site or its results — including trading or investment losses.

Changes

We may update these terms; the date above reflects the latest revision. Material changes are noted in the changelog.
