Terms of Use

Last updated: October 2026. By using fincalcs.best you agree to these terms.

Educational reference only — not investment advice

Everything on this site — calculators, simulators, guides, and worked examples — is provided for education. It is not investment, tax, accounting, or legal advice, and no content is a recommendation to buy, sell, or hold any security or product. Formulas follow standard textbook conventions (END-mode ordinary annuities, clean bond prices on coupon dates); real instruments, real fees, and real taxes differ in ways this site does not model.

No warranty

The site and its contents are provided "as is" without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, and non-infringement. Numerical results can contain errors — verify anything load-bearing against your own sources (that is also how you learn the material). To the maximum extent permitted by law, we are not liable for any damages arising from use of the site, including decisions made on the basis of a computed result.

Trademarks

BA II Plus is a trademark of Texas Instruments Incorporated; HP 12C is a trademark of HP Development Company, L.P. This site is an independent educational reference — unofficial, unaffiliated, and not endorsed by either company. References to the CFA Institute and its exams are informational; the CFA Institute does not endorse this site, and its own publications are authoritative.

Acceptable use

Use the site freely for study, teaching prep, and double-checking your work. Don't scrape it at volumes that degrade service for others, and don't republish the calculators as your own.

Changes

These terms may be updated; the date above will change with them. Questions: contact us.
