How to Use Amortization Calculator
Amortization Calculator Formula / How It Works
This calculator applies compound interest amortization mathematics to compute fixed installment payments. Each month, interest is calculated on the remaining balance, the payment is split between principal and interest, and the ending balance is updated until fully paid off.
For example, amortizing a ,000 loan at 5% APR over 36 months results in a monthly payment of .71, total interest paid of .52, and an ending balance of .00 on month 36.
Frequently Asked Questions
A loan amortization schedule is a complete table showing every periodic payment on an installment loan, detailing how much goes toward interest versus principal, and tracking the declining principal balance.
Because interest is calculated on your remaining principal balance, as your principal decreases each month, the interest portion of your fixed payment shrinks, allowing more of your payment to go toward principal.
Yes! Setting the interest rate to 0% divides your loan principal equally across all payment periods with zero interest charged.
Due to floating-point precision and rounding, slight residual fractions accumulate over multi-year schedules. Our calculator automatically adjusts the final payment to ensure your balance closes to exactly .00.
