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.
In today's market, the mortgage rate of a 5-year ARM is a 94 basis points (0.94%) lower than a comparable 30-year fixed. Rates for the 5-year ARM average 2.99% and rates for the 30-year loan average 3.93%. Because its rates are lower, 5-year ARMs save $52 per $100,000 borrowed at today's mortgage rates. Getting access to cheaper payments, though, should not be the reason you choose an adjustable-rate mortgage over a fixed-rate one.
