OptionsPriceCalculator

FAQ

Is this financial advice?
No. Options Price Calculator is for educational purposes only and is not financial advice. Nothing on this site is a recommendation to buy, sell, or hold any security or option.
How accurate are the P&L numbers?
Prices are computed with a CRR binomial model using constant implied volatility. This is an estimate, not a guarantee - no warranty is made as to the accuracy of any price or figure shown.
Why CRR instead of Black-Scholes?
CRR correctly prices early exercise on American-style options, which plain Black-Scholes ignores - this matters for deep-ITM puts and short calls held through a dividend.
Does this pull live option chains?
No. The calculator runs entirely in manual input mode - you type in strikes, premiums, and expirations yourself.
Is this free?
Yes. Options Price Calculator is free to use, with no account or subscription required.
Do I need an account?
No. There's no login, signup, or personal information required to use the calculator.
Can I use this on mobile?
Yes. Options Price Calculator works on mobile browsers, and it can also be installed as an app on your phone for offline access.
