Data Source and Methodology
All calculations are based strictly on the Black-Scholes model, a widely used tool in finance for calculating options pricing. Learn more.
The Formula Explained
$$ \sigma = \frac{IV}{S \cdot \sqrt{T}} $$
Glossary of Terms
Option Price: The market price of the option.
Underlying Price: Current price of the underlying asset.
Strike Price: The set price at which the option can be bought or sold.
Time to Expiration: The time remaining until the option expires.
Risk-Free Rate: The theoretical return of an investment with no risk of financial loss.
How It Works: A Step-by-Step Example
Let's say the option price is $10, the underlying asset is priced at $100, the strike price is $105, with 30 days to expiration and a risk-free rate of 2%. The implied volatility, calculated using the Black-Scholes model, would be displayed above.
