Comparison
ARM vs Fixed Calculator
An ARM trades certainty for a lower starting rate. Whether that's smart depends almost entirely on how long you'll keep the loan and how much rate risk you can genuinely absorb.
This model shows the fixed-period savings, then what happens if the rate adjusts to its cap, the scenario worth being honest about before you sign.

Questions people ask
- What do the numbers in a 7/6 ARM mean?
- Seven years fixed, then adjusting every six months thereafter, subject to caps on each adjustment and over the life of the loan.
- Can I refinance out of an ARM?
- Usually yes, but it isn't guaranteed, it depends on your credit, equity and market conditions at that time. Never choose an ARM assuming you'll definitely refinance.

In plain English
It compares a fixed payment against an adjustable one, including what happens when the adjustable one adjusts.
When to use it
- You expect to move or refinance within the fixed period
- The rate gap between the two is unusually wide
- You want to see the worst case before choosing
Common mistakes
- Planning on refinancing later
- Rates and circumstances may not cooperate. Choose a loan that works if nothing changes.
- Ignoring the caps
- The ceiling on adjustments is the number that matters most in a bad scenario.
- Picking on the starting rate
- The savings window is finite. Compare across your full expected time in the home.
