How It Works

Each month, interest is calculated on the remaining balance. The difference between your fixed payment and the interest charge goes toward principal reduction. This creates a gradually shifting ratio from interest-heavy to principal-heavy payments.

Formula

Monthly Interest = Balance × (Annual Rate / 12); Principal = Payment - Interest; New Balance = Old Balance - Principal

Assumptions

  • Fixed interest rate throughout loan term
  • Payments made on time each month
  • No prepayment penalties
  • Extra payments applied to principal immediately
