Acceptable use
Use any calculator for personal or classroom purposes without an account. Do not scrape the site at abusive rates, republish outputs as your own calculation service, or strip attribution from embedded widgets. Automated access must respect robots.txt and rate limits.
Estimates, not advice
Outputs are educational estimates from the formulas documented in methodology — market prices, tax rules and personal circumstances vary. Finance, health and legal tools carry their own disclaimers; our editorial policy describes checks and corrections. Continued use of the site accepts these terms.
