Greeks Portfolio & Exposure Calculator
Build any multi-leg Nifty or Bank Nifty position and instantly see its net Greeks — Delta, Gamma, Theta, Vega and Rho — and rupee exposure per lot. Add or remove legs; everything computes live in your browser.
How it works: Set the shared market inputs, then add each option leg (buy/sell, call/put, strike, lots). The tool sums every leg's Greek — weighted by side, lots and lot size — into your net position exposure.

How to read your net Greeks
- Net premium is your cash flow: negative = net debit paid, positive = net credit received.
- Net Delta in rupees is your directional P&L per 1-point Nifty move. Near zero = Delta-neutral. See Delta.
- Net Gamma tells you how fast that Delta will change on a move — positive if you are net long options. See Gamma.
- Net Theta is your daily time decay in rupees — negative if you are a net buyer, positive if a net seller. See Theta.
- Net Vega is your rupee gain for a +1% rise in implied volatility. See Vega.
Frequently asked questions
How do I make my position Delta-neutral?
Adjust legs or add an offsetting position (opposite Delta, or Nifty futures) until net Delta is near zero. Then your P&L depends on Theta and volatility rather than direction. Use the delta-hedge calculator to size the hedge.
Why does per-leg IV matter?
Real option chains have a volatility skew — each strike trades at its own IV. Enter a per-leg IV to model that; leave it blank to use the shared IV above.
Are brokerage and taxes included?
No. Figures are pre-cost. Indian trades also incur brokerage, STT, exchange and statutory charges, which matter most for high-frequency and small-edge strategies.
