Amortization Calculator with Yearly Schedule
See exactly where every payment goes. This amortization calculator splits each year of your loan into principal and interest, revealing how slowly early payments build equity — and how the balance accelerates downward over time.

How this calculator works
- Each payment first covers the month's interest (balance × rate ÷ 12); whatever remains reduces principal. As the balance falls, the interest share shrinks and payoff accelerates.
- On a 30-year loan at 6.5%, you don't reach 50% equity from payments alone until around year 19.
Frequently asked questions
Why is so much of my payment interest?
Interest is charged on the outstanding balance, which is largest at the start. A $320k loan at 6.5% accrues about $1,733 of interest in month one — most of a ~$2,022 payment.
Do extra payments change the schedule?
Yes — extra principal skips ahead on the schedule, permanently reducing the balance that future interest is computed on. See the mortgage payoff calculator.
Is amortization the same for car loans?
Yes, the same math applies to any fixed-rate installment loan — auto, personal, or student.
