Options Profit Calculator: NIFTY, BANKNIFTY & Greeks

How to use it

Pick the underlying: the NIFTY, BANKNIFTY and FINNIFTY presets fill the lot size and the strike step, and "US stock" uses 100 shares per contract. Type today's spot price, the days left to expiry and the implied volatility (IV) your platform shows. Choose a ready strategy or set the legs yourself. Leave a premium empty and the calculator prices that option with the Black-Scholes model; type the real premium from your option chain and every number follows your fill.

Reading the result

The green area of the chart is profit at expiry, the red area loss; the dashed line is the value of the same position today. Move a finger or the mouse over the chart to read the profit at any price. Max profit and max loss are at expiry. "No limit" means the loss (or profit) keeps growing as the price moves, which is the case for a short call or a short straddle: those positions need a stop and enough margin.

A worked example: a NIFTY bull call spread with spot at 26,000, buying the 26,000 call for ₹180 and selling the 26,100 call for ₹130 costs ₹50 × 65 = ₹3,250 per lot. The most it can lose is that ₹3,250; the most it can make is the 100-point width minus the cost, (100 − 50) × 65 = ₹3,250, at 26,100 or higher on expiry. It breaks even at 26,050.

The greeks in plain words

Delta: how many units of the index the position behaves like right now (+30 units gains about ₹30 for every 1 point up). Theta: what one day of time does to the position if nothing else changes; option buyers usually lose it, sellers earn it. Vega: the change for 1 point of implied volatility. Gamma: how fast delta changes as the price moves. All four come from Black-Scholes with your IV and rate, so they are estimates.

Limits of the model

NSE index options are European style and settled in cash, which suits Black-Scholes. Stock options in the US can be exercised early and pay dividends, which the model here ignores. Brokerage, STT, exchange charges and GST are not included. NSE reviews lot sizes from time to time (65, 30 and 60 since the January 2026 contracts), so check the current NSE circular before you trade.

ऑप्शन प्रॉफिट कैलकुलेटर हिंदी में

NIFTY, BANKNIFTY या FINNIFTY चुनें, फिर स्पॉट प्राइस, एक्सपायरी तक बचे दिन और IV भरें। हर लेग में Buy या Sell, Call या Put, स्ट्राइक, प्रीमियम और लॉट डालें। कैलकुलेटर एक्सपायरी पर अधिकतम मुनाफ़ा, अधिकतम नुक़सान और ब्रेक-ईवन बताता है और चार्ट में हर कीमत पर लाभ-हानि दिखाता है। प्रीमियम खाली छोड़ेंगे तो मॉडल (Black-Scholes) से कीमत ली जाएगी; असली प्रीमियम अपने ऑप्शन चेन से डालें।

ध्यान रखें: ऑप्शन बेचने (Sell) पर नुक़सान की कोई सीमा नहीं होती, और NSE लॉट साइज़ बदलता रहता है (अभी NIFTY 65, BANKNIFTY 30, FINNIFTY 60)। ट्रेड से पहले NSE का ताज़ा सर्कुलर देखें। यह केवल सीखने के लिए है, निवेश सलाह नहीं।

Questions

How is the profit of an option calculated at expiry?

A bought call is worth the price above the strike, a bought put the price below it; take away the premium paid and multiply by the lot size. Sold options are the same with the sign turned round.

What is the NIFTY lot size now?

65 units since the January 2026 contracts (BANKNIFTY 30, FINNIFTY 60). NSE reviews lot sizes, so check its latest circular.

Why is my real premium different from the model price?

Each strike trades at its own implied volatility and with a spread. Type the premium from your option chain to use your real price.

What does 'No limit' mean for max loss?

The loss keeps growing the further the price moves against the position, as with a short call. Such trades need a stop loss and enough margin.

Are taxes and charges included?

No. Brokerage, STT, exchange fees and GST lower the real result.
