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 of every monthly payment over the life of a loan, showing how much of each payment goes toward interest and how much reduces the principal balance. Early payments are mostly interest; later payments are mostly principal.
Each month's interest charge is calculated on the remaining principal balance. As payments reduce the principal, the interest portion shrinks and the principal portion grows — even though the total payment stays the same. This is the core mechanic of an amortizing loan.
This calculator shows the standard amortization schedule for a fixed monthly payment without additional payments. To model the impact of extra payments on your payoff date and total interest, use the EMI Calculator and adjust your scenarios manually.
Yes. Any fixed-rate, fixed-payment installment loan follows the same amortization math. Enter the loan amount, interest rate, and term to generate a full payment schedule for a mortgage, auto loan, or personal loan.
Yes. The schedule is generated using the standard amortization formula with double-precision arithmetic. Results match typical bank statements. Minor differences can arise from bank-specific rounding conventions applied at the payment level.
