An adjustable rate mortgage (ARM) is a type of mortgage loan with specific rate terms. An ARM is usually initially fixed for a set period of time, followed by periodic adjustments according to a specific benchmark.

Other Factors:

There are various factors that determine the interest rate changes including market conditions, financial index and a margin. The index is a measure of interest rates generally, and the margin is an extra amount that the lender adds.

The initial rate and payment amount on an ARM will remain in effect for a limited period ranging from just 1 month to 5 years or more. With most ARMs, the interest rate and monthly payment change every month, quarter, year, 3 years, or 5 years. The period between rate changes is called the adjustment period. For example, a loan with an adjustment period of 1 year is called a 1 year ARM, and the interest rate and payment can change once every year.


  • Typically, you are offered a lower interest rate early in the loan term which equates to lower monthly payments.
  • You can take advantage of falling rates without having to refinance.
  • You may end up with a lower monthly payment if rates drop.

Is an Adjustable-Rate Mortgage Right for You?

An adjustable rate mortgage (ARM) may be a good option for you if:

  • You have plans to move within the initial locked-in period when the rate cannot change.
  • You plan on utilizing the payment savings to aggressively pay down principal.
  • Expect your income to increase in the next couple of years.
  • You want the benefit of a lower initial rate and monthly payment.
  • You have a lump sum of money coming your way before it adjusts where you could pay the house off at that time or significantly reduce the principal.
