How the amortization calculator works
An amortization schedule shows how a fixed loan payment is split over time. Early on, most of each payment is interest; as the balance falls, more goes to principal, until the loan is fully paid off.
Each month: interest = balance × r, principal = payment − interest
Frequently asked questions
Why is early interest so high?+
Interest is charged on the outstanding balance, which is largest at the start. As you pay down principal, the interest portion of each payment shrinks.
Can I see it month by month?+
This view summarizes by year to stay readable. The totals match a full monthly schedule to the cent.
