How This Calculator Works

This calculator uses the standard loan amortization formula: Monthly Payment = P × [r(1+r)^n] / [(1+r)^n - 1] Where: • P = Principal (loan amount) • r = Monthly interest rate (annual rate ÷ 12) • n = Total number of payments Each payment consists of: 1. Interest portion = Remaining balance × monthly rate 2. Principal portion = Monthly payment - interest Early payments are mostly interest; later payments are mostly principal.
