How the payoff math works in Naperville
Velocity Banking parks your monthly surplus inside the HELOC so daily interest accrues on a smaller balance. On a typical Naperville home, the 85% CLTV ceiling leaves around $177,000 accessible — but the size of the line is rarely what decides the outcome. The monthly surplus and the spread between the HELOC's APR and your mortgage rate do.
The model below runs your actual balance, rate, and surplus day by day, projects a payoff date, and lets you stress-test what happens if the HELOC rate rises. Nothing here is a guarantee — results depend on discipline, the rate path, and whether you qualify.
