Call Option Calculator
A Call Option Calculator helps traders estimate the value of a call option using the Black-Scholes formula. This tool considers factors such as the stock price, strike price, volatility, time to expiration, risk-free interest rate, and dividends. With this calculator, you can make informed decisions about buying or selling options, helping to maximize profits or minimize risks.
Formula for Call Option
The Black-Scholes formula for calculating the price of a call option is:
C = S * N(d1) - X * e^(-r*T) * N(d2)
where:
d1 = [ln(S / X) + (r + σ² / 2) * T] / (σ * √T)
d2 = d1 - σ * √T
S = Current stock price
X = Strike price
T = Time to expiration (in years)
r = Risk-free interest rate
σ = Volatility (standard deviation)
N = Cumulative normal distribution
