The Options Calculator is a tool that allows you to calcualte fair value prices and Greeks for any U.S or Canadian equity or index options contract. Theoretical values and IV calculations are performed using the Black 76 Pricing model, which is different than the Greeks calculated and shown on the symbol's Volatility & Greeks page which used the Binomial Option Pricing model.
- Enter any U.S or Canadian equity or index symbol (IBM, SPY, $SPX, etc.)
Result: The calculator finds the nearest expiration date and call strike price closest to the last price of the underlier and fills in the input parameters on the page. If a U.S. equity, we use the latest Cboe BZX real-time price as the last price.
- You can adjust the option type, expiration date, and strike price to use.
- You may also adjust any of the input parameters shown on the left side of the page.
Result: As input parameters are adjusted, the Theoretical Values are recalculated on the right side of the page.
- You may also select the Market Option Price (Last, Bid, Ask, Mid, Theoretical) to recalculate the Implied Volatility.
The page also includes a number of "Quick Links" that allow you to further analyze the selected option in the calculator.
