An ARM starts with a fixed interest rate for an initial period, then adjusts periodically based on market conditions. This can offer lower initial payments. Lower Initial Rate Start with a lower interest rate and monthly payment than fixed-rate loans. Short-Term Ownership Ideal if you plan to sell or refinance before the rate adjusts. Rate Caps Initial, periodic, and lifetime caps limit how far the note rate can move. Read [ARM caps in plain English](/blog/arm-caps-in-plain-english/). Understand the Risks Rates can increase, potentially raising your monthly payment over time. ### How caps work (as of 2026-08) Caps are often written as initial / periodic / lifetime, for example 2/1/5. Those numbers are percentage-point limits on how far the note rate can move, not a promise of what it will do. - **Initial.** The initial adjustment cap limits the first rate change after the fixed period. - **Periodic.** The periodic cap limits later adjustments (often each year after the first change). - **Lifetime.** The lifetime cap is the maximum the rate can rise above the start rate over the life of the loan. After the fixed period, the rate is typically index plus margin, then limited by the caps. Many current ARMs use a SOFR-based index. This page does not quote a current ARM start rate. A cap on the rate is not a cap on taxes, insurance, or HOA. The full payment can still rise when those change.

Often used when the plan is to sell or refinance before the first adjustment — not a promise that you will. #### 7/1 ARM Fixed rate for 7 years, then adjusts annually. #### 10/1 ARM Fixed rate for 10 years, then adjusts annually. Longer fixed period, still an ARM after that date. Interest-only is a different payment machine: principal is not required during a stated period. That is not an ARM teaser and not a temporary buydown. [Interest-only: who it is for](/blog/interest-only-mortgages-who-they-are-for/). ### Is an ARM Right for You?
