How to Use This Option Calculator

This free option calculator uses the Black-Scholes model to calculate theoretical option premiums and Greeks for NIFTY and BANKNIFTY options.

Understanding the Greeks:

Delta: How much option price changes when underlying moves Rs 1
Gamma: Rate of change of Delta
Theta: Daily time decay (how much value lost per day)
Vega: Sensitivity to 1% change in volatility

Use the P&L scenarios to see potential profit/loss at different price levels.
