How this calculation works
The adjustable loan uses the initial rate until the first reset, then recalculates payments on the remaining balance and term. The entered reset rate stays fixed thereafter. Compare with keeping the original fixed rate.
One reset scenario only. Lifetime caps, periodic caps, indices, margins and later resets must be accounted for in the assumed rate.
How do I use this calculator?
Enter your own figures in each labeled field. Review the assumptions above, then compare the result with a second set of inputs. Reset restores the illustrative example values.
Can I save and compare scenarios?
