Price Your Options

Enter the underlying price, strike price, time to expiration, risk-free rate, and implied volatility. The calculator computes theoretical option prices using Black-Scholes along with all Greeks (Delta, Gamma, Theta, Vega). It helps evaluate whether an option is overpriced or underpriced relative to theoretical value.

Key Components

  • Underlying Asset Price: Current spot price of stock/index.
  • Strike Price: Agreed execution price.
  • Time to Expiration: Days remaining until contract expiry.
  • Volatility: Expected annual price fluctuation (IV %).
  • Risk-Free Rate: Prevailing interest rate.

How It Works

Uses Black-Scholes formula:

  • Call Option Value: S·N(d₁) - K·e⁻ʳᵀ·N(d₂)
  • Put Option Value: K·e⁻ʳᵀ·N(-d₂) - S·N(-d₁)
