NSE Option Price Calculator Option Price CalculatorWork out what an option should be worth before it expires. The calculator prices a contract from the NSE spot price and the implied volatility we already hold, then lays out strike by strike what you would make or lose and what that is as a percentage return — so a mid-cycle exit becomes a number rather than a guess.

Frequently asked questions
How does the option price calculator work?
It prices the contract from the NSE spot price and the implied volatility stored in our database, along with the time left to expiry. Change the spot you expect or the date you expect to exit, and every strike is repriced under that assumption.
Where does the implied volatility come from?
From our own stored copy of NSE data for that contract, rather than a typed-in guess. That is what makes the estimate specific to the strike you are actually looking at.
Can it tell me which strike to buy?
It shows what each strike would return under the view you enter, which is the information that decision needs. It is not advice, and the numbers are estimates — real fills depend on liquidity, volatility changing and the spread.
Why is my broker showing a different premium?
A theoretical price assumes the volatility and time inputs it is given. Live premiums also carry the bid-ask spread, demand at that strike and volatility that has moved since the stored figure. Treat the calculator as an estimate of fair value, not a quote.
