What is an amortization schedule?

An amortization schedule is a table showing each periodic payment on a loan, breaking down how much goes to interest versus principal, and showing the remaining balance after each payment.

Why do I pay more interest early in the loan?

Interest is calculated on the remaining balance. Since the balance is highest at the beginning, more of each early payment goes toward interest. As you pay down the balance, more goes toward principal.

How do extra payments affect amortization?

Extra payments reduce your principal faster, which reduces the interest charged in subsequent months. This can significantly shorten your loan term and reduce total interest paid.

Can I change my amortization schedule?

You can alter your effective amortization by making extra payments, refinancing to a different rate or term, or recasting your mortgage after a lump-sum payment.

Warning

With less than 5% down payment, you'll face higher interest rates, larger PMI premiums, and limited lender options. Many programs require at least 3-3.5% down.

An amortization schedule shows exactly how each mortgage payment is divided between principal and interest over the life of your loan. Early payments go mostly toward interest, while later payments go mostly toward principal.
