How Mortgage Calculations Work

This calculator uses the standard mortgage payment formula (PMT). The monthly payment is calculated using:

M = P[r(1+r)^n] / [(1+r)^n - 1]

Where M is the monthly payment, P is the principal (loan amount), r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments.

The amortization schedule shows how each payment is split between principal and interest over the life of the loan. Early payments go mostly toward interest, while later payments go mostly toward principal.
