Adjustable-rate mortgage (ARM)[skip to next word] A mortgage in which your interest rate and monthly payments may change periodically during the life of the loan, based on the fluctuation of an index. Lenders may charge a lower interest rate for the initial period of the loan. Most ARMs have a rate cap that limits the amount the interest rate can change, both in an adjustment period and over the life of the loan. Also called a variable-rate mortgage.
