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) and fixed rate home loans with shorter terms offer lower rates than the ever-popular 30-year fixed loan. If you can budget the higher monthly payment of the 15-year fixed or 10-year fixed loan, or if you're comfortable with the possibility of your rate changing with the ARM, these options could help you get a better refinance rate for your home loan and pay much less interest over time.
