An explanation of the Black-Scholes formula

The Black-Scholes formula standard is:

Call Option Price = S × N(d1) − K × e⁻ϳᵀ × N(d2)

Put Option Price = K × e⁻����� × N(−d2) − S × N(−d1)

Where:

Black Scholes Model Calculation of N(d1)

This is the d1 formula:

d1 = [ln(S/K) + (r + σ²/2)T] / (σ√T)
d2 = d1 − σ√T

The likelihood that the option will expire in the money is represented by N(d1).
