Adjustable Rate Mortgage (ARM)
An Adjustable Rate Mortgage (ARM) is a home loan with an interest rate that fluctuates over its term. It typically starts with a lower introductory rate before adjusting periodically based on market conditions, leading to potentially variable monthly payments.

What is an Adjustable Rate Mortgage (ARM)?
An Adjustable Rate Mortgage (ARM) is a type of home loan where the interest rate is subject to change over the life of the loan. Unlike fixed-rate mortgages that maintain a consistent interest rate, ARMs typically begin with a lower introductory interest rate for a set period. After this initial period, the interest rate adjusts periodically, usually annually, based on a benchmark index plus a margin.
The adjustments to the interest rate on an ARM can lead to fluctuations in the borrower’s monthly payment. If market interest rates rise, the borrower’s monthly payment will increase, potentially making the mortgage more expensive over time. Conversely, if market interest rates fall, the monthly payment could decrease.
ARMs are often utilized by individuals who anticipate moving or refinancing before the initial fixed-rate period ends, or those who believe interest rates will decline in the future. The initial lower rate can provide greater affordability in the short term, making it attractive for some buyers. However, the potential for rising payments introduces a degree of risk and uncertainty into long-term homeownership costs.

Key Takeaways
- ARMs feature an interest rate that can change over the loan’s life, unlike fixed-rate mortgages.
- They typically offer a lower initial interest rate for a predetermined period before adjustments begin.
- Monthly payments can increase or decrease depending on market interest rate fluctuations.
- ARMs are often considered by borrowers who plan to sell or refinance before the adjustment period or expect rates to fall.
- Potential for increased future payments introduces risk, but initial lower payments can improve affordability.
Understanding Adjustable Rate Mortgages (ARMs)
The structure of an ARM involves several key components that dictate how the interest rate changes. An index is a publicly available benchmark interest rate that ARMs are tied to, such as the Secured Overnight Financing Rate (SOFR) or the Cost of Funds Index (COFI). A margin is a fixed percentage added to the index by the lender to determine the ARM’s fully indexed rate.
ARMs also have caps that limit how much the interest rate can increase. These include an initial adjustment cap, which limits the first rate increase, and periodic adjustment caps, which limit subsequent increases. There is also often a lifetime cap, which sets the maximum interest rate the loan can ever reach. These caps provide some protection against extreme payment shocks, though the potential for rising payments remains.
