常见问题
What does 5/1 ARM mean?
A 5/1 ARM has a fixed rate for the first 5 years, then adjusts every 1 year after that. Enter these intervals in the setup fields.
How high can the rate go?
Rate caps limit increases per adjustment period and over the loan life. Enter your cap values and the calculator projects the worst-case payment.
What is the index margin?
The margin is added to the index rate (like SOFR) to determine your adjusted rate. Enter the margin from your loan terms on the setup sheet.
Is the worst-case scenario shown?
Yes. The dashboard shows the worst-case payment amount if the rate hits the lifetime cap, alongside the initial and expected adjusted payments.
