Amortization explains how a fixed-rate mortgage shifts from interest-heavy payments early on toward more principal later. Use this calculator to visualize that tradeoff and understand how extra payments change the schedule.

Reading The Schedule
What to watch in an amortization table
Principal share
This is the part of each payment that actually reduces the loan balance.
Interest share
This is the borrowing cost for that month and is highest early in the schedule.
Remaining balance
The balance helps you see how quickly equity builds and how long the loan still has to run.
Extra-payment effect
When extra principal is added, the balance falls faster and later interest charges shrink.
FAQ
Amortization calculator questions
What is an amortization schedule?
An amortization schedule is a month-by-month breakdown of each payment, showing how much goes to principal, how much goes to interest, and what balance remains.
Why is so much of the payment interest at the beginning?
Because interest is calculated on the outstanding balance, and the balance is highest early in the loan term.
Can extra payments change the amortization schedule?
Yes. Extra payments reduce principal sooner, which lowers future interest and changes the pace at which the balance falls.
