DEFINITION of 'ARM Index'. The benchmark interest rate to which an adjustable rate mortgage is tied. An adjustable rate mortgage's interest rate consists of an index value plus a margin. The index underlying the adjustable rate mortgage is variable, while the margin is constant. There are several popular indexes used for different types of adjustable rate mortgages. This is also referred to as the fully indexed interest rate.
Adjustable rate mortgage (ARM). An adjustable rate mortgage is a long-term loan you use to finance a real estate purchase, typically a home. Unlike a fixed-rate mortgage, where the interest rate remains the same for the term of the loan, the interest rate on an ARM is adjusted, or changed, during its term. The initial rate on an ARM is usually lower than the rate on a fixed-rate mortgage for the same term, which means it may be easier to qualify for an ARM. You take the risk, however, that interest rates may rise, increasing the cost of your mortgage.
