What's An Easy Way To Calculate Implied Volatility?

Calculating implied volatility (IV) is more of a backwards-type calculation.

Since IV is “implied” through each option price itself, you’ll first need to know the price of the option you’re considering and then run that price through an option calculator. You can use this one from the CBOE.

At the bottom-right corner of that calculator, you’ll see the box that will help you solve for IV.
