Frequently Asked Questions about the Amortization Calculator

What is an amortization schedule?

An amortization schedule shows each payment broken into principal and interest portions, plus remaining balance after each payment.

Why do early payments have more interest?

Because interest is calculated on the remaining balance. Early on the balance is highest, so more of each payment goes to interest.
