How it works
Use this calculator to compare an adjustable-rate mortgage with a fixed mortgage.
What this calculator does
The ARM vs fixed mortgage calculator compares fixed payment, ARM intro payment, adjusted ARM payment, and intro-period savings.
ARM vs Fixed Formula
The calculator amortizes the ARM during the intro period, then recalculates payment at the adjusted rate.
Example calculation
If a fixed mortgage rate is 6.5% and an ARM starts at 5.5% for 5 years, the calculator estimates intro savings and the adjusted payment.
When to use this calculator

FAQs
