Frequently asked questions
What is amortization?
Paying off a loan with equal regular payments. Early payments are mostly interest; as the balance falls, more of each payment goes to principal.
Do extra payments go to principal?
They should — ask your lender to apply extra payments to principal, not to future payments.
