It estimates payments on an adjustable-rate mortgage across the fixed introductory period and the adjustment periods that follow, including worst-case rate caps.
ARM in Florida
ARMs can appeal to Florida buyers who expect to sell or refinance before the fixed period ends — common in a state with seasonal residents and frequent relocations. Just stress-test the worst case: if you might still own the home when it adjusts, make sure the capped payment is one you could absorb.
The calculator amortizes at the low intro rate during the fixed period, then projects payments at the maximum the rate can reach under the caps, so you see both the best case and the worst case after the loan adjusts.

Frequently Asked Questions
What does 5/1 ARM mean?
The rate is fixed for the first five years, then adjusts once a year after that. The new rate is set by an index plus a margin, limited by the loan's rate caps.
Is an ARM riskier than a fixed loan?
It can be, because the payment can rise after the fixed period. The risk is bounded by the caps, and it is lower if you plan to sell or refinance before the loan adjusts.
