What is an Options Calculator?

The Options Calculator is a real-time, easy-to-use tool that helps investors calculate a contract’s theoretical value, price change, and changes in Greeks under selected parameters. To use the options calculator, you just need to select the calculation date, underlying price, implied volatility, and risk-free rate. The theoretical value and price changes will be calculated automatically based on selected parameters.

Please note: We only support the calculation of single options. The calculated result is theoretical and for reference only. The theoretical price uses basic assumptions from the Black-Scholes Model, which may differ from the actual market price.

What Parameters are Included?

Date: set a date ranging from the current date to the expiration date to calculate the theoretical price during that time frame.

  • Underlying Price: set a target price for the options’ underlying security.
  • Implied Volatility: set a value for the implied volatility for the options’ symbol.
  • Risk Free Rate: the default value is 1%.
