Amortization, explained
The schedule showing how each loan payment is split between interest and principal over time.
What it means
Amortization is the process of paying down a loan through regular installments that cover both interest and principal. Your lender provides an amortization schedule that lists every payment for the life of the loan and shows exactly how much of each payment reduces your balance versus how much goes to interest. Early payments are interest-heavy because interest is calculated on the outstanding balance. As you pay down principal, the interest portion shrinks and more of each payment chips away at what you owe.
Why it matters
Understanding your amortization schedule tells you when you'll reach positive equity and how much you actually pay in total interest. On a 72-month auto loan at 7%, you might pay $4,000 in interest over six years on a $25,000 car. The schedule also shows that paying extra toward principal early in the loan saves far more interest than extra payments near the end. If you refinance or pay off the loan early, the schedule helps you see exactly how much you'll save.
What to do
Request your amortization schedule from your lender or generate one using any online calculator with your loan amount, rate, and term. If you're considering paying extra each month or refinancing to a lower rate, compare schedules side by side.
