This options calculator tool helps you calculate potential profits and losses from trading options.

## 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.
