Implied volatility is the market's forecast of a likely movement in a security's price. IV is often used to price options contracts where high implied volatility results in options with higher premiums and vice versa. Supply and demand and time value are major determining factors for calculating implied volatility.

Implied Volatility (IV) uses an option price to determine and calculate what the current market is talking about, the future volatility of the option's underlying stock. Implied volatility is one of the six essential factors used in options pricing models.

Implied volatility is calculated by taking the market price of the option, entering it into the Black-Scholes formula, and back-solving for the value of the volatility.

The Rule of 16 is a way to estimate the 1-day expected move of any security based on evaluating its implied volatility and dividing that number by 16. For the market in general (SPX), this can be done by dividing the VIX by 16 since the VIX is the implied volatility of SPX (roughly 23-37 days out).

Thus the implied volatility must be calculated numerically. In general, this calculation is accomplished by feeding the value-price difference: C(σ) − C_M into a root-finding program, where C(·) is an option pricing formula, σ is the volatility parameter, and C_M is the observed market price of the option.

Implied volatility is calculated by taking the market price of an option and backing out the implied volatility that results in the market price given a particular option pricing model and other input parameters.
