Can you please share the formulla how to calculate it .I want to import this formulla in excel sheet .

Hi, Thank you. This is really a cool tool and almost accurate.

Just a simple update to this would be, after every calculation the values are reset to the default value in the calculator. If you could update that to use the values that the user used in the last calculation would be really great.

Thanks.

In this calculator, the price of deep in the money put option keeps falling as you move farther out or increase the days to maturity. Why does that happen. In foreign calculators, the price increases. Also, if you look at nifty option chain, the price of 11000 strike put option is almost same for April and December expiry, when spot price is around 8000.

Is there a mistake in your calculator.
