How To Calculate Value Of Stock Options

Stock options are a popular financial instrument that gives individuals the right, but not the obligation, to buy or sell a specific amount of a stock at a predetermined price within a specified time frame. Calculating the value of these options involves complex mathematical formulas. This article introduces an online calculator to simplify the process of determining the value of stock options.

Formula: The Black-Scholes formula is commonly used to calculate the theoretical price of European-style stock options. It considers factors such as stock price, strike price, time to expiration, volatility, and interest rate. The formula involves the cumulative distribution function (CDF) for the standard normal distribution.

How to Use:

  1. Enter the current stock price.
  2. Input the strike price of the stock option.
  3. Specify the time to expiration in years.
  4. Provide the volatility of the underlying stock in percentage.
  5. Enter the interest rate in percentage.
  6. Click the “Calculate” button to get the estimated option price.

Example: Suppose the current stock price is $100, the strike price is $95, time to expiration is 0.5 years, volatility is 20%, and the interest rate is 5%. After entering these values into the calculator and clicking “Calculate,” the estimated option price is displayed.
