How it works

How velocity banking works

Step one: the line replaces the mortgage

At closing, the line pays off the existing mortgage. There is no longer a separate loan with a separate payment. The line balance is the debt.

The line is written in first position, which is what makes it large enough to do this — a second-lien home equity line sits behind an existing mortgage and is typically limited to whatever equity is left over.

Step two: income lands on the line

Your income is deposited into the line rather than a checking account. It reduces the balance on the day it arrives, not at the end of a statement cycle.

That timing matters because interest is calculated daily. A deposit that lands on the third of the month lowers the balance for every remaining day of that month.

Step three: expenses draw back off it

Bills, groceries, escrows and everything else are paid from the line. Each draw raises the balance again.

Over a month the balance follows a sawtooth: down sharply on payday, walking back up as you spend, down again on the next payday. What matters is where it closes relative to where it opened.

Step four: interest is charged on the actual daily balance

Each day, interest accrues on the balance as it actually stands that day. At the end of the month those daily amounts are added together and billed once.

This is the mechanical heart of the strategy, and it is worth being precise about it: interest is charged on the actual daily balance, not on an average, and not on the balance at the start of the month.

Step five: the surplus compounds

If income exceeds expenses plus interest, the balance closes the month lower than it opened. Next month starts from that lower balance, so the interest charged is smaller, so more of the same surplus goes to principal.

That is the entire engine. It is not exotic — it is what happens whenever principal comes down earlier than scheduled.
