Theoretical value is a model estimate, not a quote. American exercise, discrete dividends, liquidity, and jumps can produce different market prices.
How to use the Black-Scholes option price calculator
Enter the current underlying price, option strike, calendar days remaining, annualized implied volatility, continuously compounded risk-free rate, and dividend yield. The calculator converts days to years and estimates value with the standard Black-Scholes formula.
The model assumes lognormal prices, constant volatility and rates, continuous trading, and European exercise. American equity options, discrete dividends, volatility skew, jumps, liquidity, and early exercise can produce different market values. Use the estimate as a consistent benchmark rather than a quote.
