About ARM Mortgages

An Adjustable Rate Mortgage (ARM) features an interest rate that changes over time. ARMs typically start with a lower fixed rate for an introductory period (e.g., 5 years for a 5/1 ARM), then adjust periodically based on market rates.

How to use: Enter your loan amount, initial rate, fixed period length, expected adjusted rate, and total loan term. The calculator shows both your initial and adjusted payments, helping you evaluate affordability.

Decision factors: ARMs are best when you plan to sell or refinance before rate adjustment, expect rates to decrease, or want lower initial payments. Consider rate caps, index used, and worst-case scenarios.
