Mortgage calculator

Loan amount info message.

$

The term of your mortgage loan is how long you have to repay the loan. For most types of homes, mortgage terms are typically 15, 20 or 30 years.

An interest rate on a mortgage loan is the cost you will pay each year to borrow the money, expressed as a percentage rate. It does not reflect fees or any other charges you may have to pay for the loan. For example, if the mortgage loan is for $100,000 at an interest rate of 4 percent, that consumer has agreed to pay $4,000 each year he or she borrows or owes that full amount.
