Option price and Greeks calculator
Enter spot, strike, days to expiry and implied volatility to get the Black-Scholes price and Greeks.
What the Greeks mean
Delta: how much the option moves for a 1-point move in the underlying. Gamma: how fast delta changes. Theta: premium lost per day from time decay. Vega: premium change for a 1-point change in implied volatility.
Black-Scholes assumes European exercise and constant volatility; index options on NSE are European, so it is a reasonable guide.
