DEFINITION of 'Variable Rate Mortgage'. A type of home loan in which the interest rate is not fixed. The two most common types of mortgages in the United States are fixed rate and variable rate (also called adjustable rate). With a fixed rate mortgage, the interest rate does not change for the entire loan term. Borrowers know with certainty what the interest and principal payment on their mortgage will be each month for as long as they carry the mortgage. With a variable rate mortgage, the interest rate adjusts periodically.
(June 2007). A fixed interest rate loan is a loan where the interest rate doesn't fluctuate during the fixed rate period of the loan. This allows the borrower to accurately predict their future payments. Variable rate loans, by contrast, are anchored to the prevailing discount rate. A fixed interest rate is based on the lender's assumptions about the average discount rate over the fixed rate period. For example, when the discount rate is historically low, fixed rates are normally higher than variable rates because interest rates are more likely to rise during the fixed rate period.
