The implied volatility formula is a key tool in the financial market for determining the expected volatility of a financial instrument, such as a stock or option, based on current market prices. Using the implied volatility formula, traders and investors can better understand the risk associated with their investments and make more informed decisions. This article provides a comprehensive guide to using the implied volatility formula in Microsoft Excel, a popular spreadsheet software.
Understanding Implied Volatility
Implied volatility is the implied level of volatility that exists in the market based on the current prices of a financial instrument. It is calculated by using the Black–Scholes model, which is a mathematical model that describes the price of a stock option based on the underlying stock price, volatility, expiration date, and other factors. The Black–Scholes model was originally developed in the 1970s and has since been modified and improved upon, but it remains a fundamental tool in options trading today.
Calculating Implied Volatility in Excel
To calculate implied volatility in Excel, you first need to input the current price, volatility, and expiration date of the option you are interested in. You can then use the implied volatility formula in Excel to calculate the implied volatility.

2. On a new worksheet, enter the following data:
A1: Current Option Price
