How Does the Black-Scholes Model Use Implied Volatility?

The Black-Scholes model is a theoretical framework used to estimate the fair price or premium of a European-style option. It requires five inputs: the underlying asset's price, the option's strike price, the time to expiration, the risk-free interest rate, and the volatility.

In practice, traders use the known option price and solve the formula backward for the volatility, which is the implied volatility. Therefore, IV is an output when pricing options in the market, but it's an input when using the model to calculate a theoretical price.
