How to Use the Options Calculator

Enter the required parameters into the form fields and click the “Calculate” button. The calculator will compute the price of a call or put option based on the Black-Scholes formula.

Parameters Explanation

  • Option Type: Choose whether you are calculating a Call or a Put option.
  • Underlying Price: The current price of the underlying asset.
  • Exercise Price (Strike Price): The price at which the option can be exercised.
  • Time to Expiry: The time remaining until the option expires, represented in years.
  • Volatility: The standard deviation of the asset’s returns, represented as a decimal (e.g., 0.2 for 20%).
  • Risk-Free Rate: The return on a risk-free investment, represented as a decimal (e.g., 0.05 for 5%).

Calculation Methodology

The calculator uses the Black-Scholes formula to compute the price of the option:

Call Option Price: ( C = S cdot N(d_1) – X cdot e^{-rT} cdot N(d_2) )

Put Option Price: ( P = X cdot e^{-rT} cdot N(-d_2) – S cdot N(-d_1) )

Where:

  • ( d_1 = frac{ln(S / X) + (r + 0.5sigma^2)T}{sigma sqrt{T}} )
  • ( d_2 = d_1 – sigma sqrt{T} )
  • ( N(x) ) is the cumulative distribution function of the standard normal distribution.

Limitations

  • The calculator assumes constant volatility and interest rates.
  • It does not account for dividends or other payouts on the underlying asset.
  • The model assumes that the markets are frictionless, with no transaction costs.
