About Amortization Schedule Calculator

The Amortization Schedule Calculator builds a complete month-by-month repayment table for any fixed-rate loan. From the loan amount, annual interest rate and term in years, it computes the monthly payment, the total interest and the total amount paid over the life of the loan.

Each row of the schedule shows one payment split into interest and principal, plus the remaining balance afterward. Early payments are mostly interest because interest accrues on a large balance; as the balance falls, more of each identical payment goes to principal — that shifting split is what amortization means.

Generate a schedule before signing a mortgage, car loan or personal loan to see exactly where each payment goes, how much interest a longer term really costs, and what your balance will be at any point. Free and instant, right in your browser.

Frequently asked questions

It is a table listing every payment on a loan, showing how much of each one covers interest, how much reduces principal, and the balance that remains. It maps the full path from the original amount to zero.

It uses the standard amortization formula P × r ÷ (1 − (1 + r)^−n), where P is the loan amount, r the monthly rate (annual rate ÷ 12) and n the number of monthly payments.

Interest each month equals the monthly rate times the current balance. At the start the balance is at its largest, so interest consumes most of the payment. As principal shrinks, the split reverses.

Monthly figures are rounded to cents, so tiny differences accumulate over the term. The calculator adjusts the final payment to clear the exact remaining balance and leave the loan at zero.

Treat them as estimates, not financial advice. The schedule assumes a fixed rate, equal monthly payments and no fees; real loans may add origination fees, insurance, variable rates or different day-count rules.
