Also called a variable-rate mortgage, an adjustable-rate mortgage has an interest rate that may change periodically during the life of the loan in accordance with changes in an index such as the U.S. Treasury-Index (T-Bill) or the Secured Overnight Financing Rate (SOFR) published daily by the New York Fed. Bank of America ARMs generally use SOFR as the basis for ARM interest rate adjustments. Note: Bank of America is not affiliated with the New York Fed.

Your monthly payment may fluctuate as the result of any interest rate changes, and a lender may charge a lower interest rate for an initial portion of the loan term. Most ARMs have a rate cap that limits the amount of interest rate change allowed during both the adjustment period (the time between interest rate recalculations) and the life of the loan.
