The short version

People ask me about velocity banking after they’ve sat through the webinar, so I tested it against 36 years of real mortgage rates. The version they sell, where you borrow on a line of credit to make big chunk payments on your mortgage, never beat simply sending the same dollars straight to the mortgage.

Not once in 378 five-year test cases, and the average household finished about $12,000 behind someone who just paid extra and refinanced when rates dropped, before paying for the program.

The chunking itself turned out to be roughly a wash. The money was lost by following the program’s advice to stop refinancing, which raises the question I’d put to anyone who’s been pitched: if the trick itself saves nothing, what exactly are you paying for?

What velocity banking is, and why it sounds right

Velocity banking comes in two flavors, and the webinar usually shows you the first. You open a home equity line of credit behind your mortgage, borrow a chunk, say $10,000, and send it to your mortgage as a principal payment. Then you run your paycheck through the line, pay your bills from the line, and whatever is left each month pays the chunk down. When the line is back to zero you borrow another chunk and repeat.

In the second flavor, sold mostly by lenders, your mortgage itself becomes the line: a first-mortgage sweep account where your paycheck lands against the loan balance and your spending comes back out.

Both come with the same piece of advice: stop refinancing. Lenders profit from refinances, the pitch goes, so a serious homeowner stops feeding them. Hold onto that advice. It turns out to matter more than the chunks.

The pitch rests on real facts. A line of credit charges interest daily on what you owe, so every dollar parked there saves a little interest until you spend it. Your mortgage charges interest monthly on a balance that only moves when you pay.

Put those together and it feels like you’ve found a gap you can drive through: get the big balance down early, let your paycheck sit against the small balance, and watch the years fall off.

Then comes the demonstration. On one side of the screen a family pays their mortgage normally and takes 30 years. On the other, the same family uses the system and finishes in seven. The difference looks like magic.

I’ve watched a lot of these demos. The seven-year family is sending every spare dollar they have at the debt. The 30-year family is sending nothing extra. The demo is testing whether paying more gets you out of debt sooner, and nobody needed a webinar to answer that. So I ran the test the demo skips: same dollars, both sides.

What we tested

I built a household: a $400,000 mortgage, $10,000 a month of income, and $2,000 a month left over after the regular payment. Then I ran that household through 378 five-year test cases, one starting every month from January 1990 on, using actual rates (mortgage rates, prime, and the Fed’s short rate). Every version got the exact same money every month. The only thing that changed was the plumbing.

One household did what I’d tell a client to do: send the extra $2,000 to the mortgage every month and, when rates fall enough to matter, refinance at no cost and keep the payment the same.

One ran the second-lien version with $10,000 chunks and no refinances, as sold. One ran the sweep account. For the two velocity versions I also ran a copy with the typical $6,000 program fee added at the start.

Then I looked at who owed less after five years.

What we found

The second-lien version, the one in the webinar, lost all 378 test cases to the household that paid extra and refinanced when rates dropped. Not once was it ahead. The average household finished about $12,000 behind over five years, and about $20,000 behind once the program fee is counted. The worst case, starting in May 1990, finished $36,000 behind.

Here’s the part that surprised me. When I let the velocity household refinance too, the chunking itself cost only a few hundred dollars over five years. The chunks are nearly a wash. Almost all of the $12,000 came from the one piece of advice that travels with the program: don’t refinance.

Over those 36 years, the household that refinanced when rates fell picked up about $12,000 per five-year case on average. That’s not a coincidence. That’s the same money. The structure got the credit, and the advice to stand still paid the bill.

The sweep account did better, and I want to be fair about that. Before fees it beat the paid-extra household in about one case in five. After fees, about one in 20. Every one of those wins started in the months just before a big drop in rates: 1990 and 1991, 2001 and 2002, and 2008 through 2010.

The sweep’s best five years in history began in August 2008 and finished about $16,000 ahead. Its worst finished about $77,000 behind. To win with it, you had to pick the structure before rates collapsed. That’s a forecast, not a feature.

The family that bought in January 2021, when rates were near 3%, is the one I think about. The paid-extra household locked 2.9% and never needed to refinance. The sweep household rode a rate tied to the Fed straight into 2022 and finished about $75,000 behind on identical money. That was when the product was being marketed hardest.

What the other side can rightly say

The sweep’s wins were real. When rates fall fast, a loan that reprices every month beats a fixed loan that steps down one refinance at a time. In a 2008 kind of world, it won.

But look at when those wins happened: 1990, 2001, 2008. Rates don’t collapse because things are going well. They collapse because something broke, and the same months that made the sweep win on rate were the months lenders were mailing freeze letters. Even with a crystal ball, you’d be picking the product in exactly the year it was most likely to be taken away.

The interest you’d save by parking your paycheck against the balance is real too, maybe $15 to $30 a month for this household. Small, but it’s real.

And there’s the discipline argument: some people won’t send the extra money unless a system makes them. I take that seriously. But it’s an argument about the person, not the product, and it means you’re paying $6,000 for a commitment device. There are cheaper ones.

What this test doesn’t cover matters too. The five-year cases overlap, so 378 is a count of starting months, not 378 independent trials; since 1990 there have been maybe five distinct rate environments. The numbers are before taxes.

And I left out the thing that cuts hardest against velocity: in 2008 and 2009, lenders froze and cut home equity lines by the hundreds of thousands, right when the strategy was winning on rate.

Here’s what that looked like. In January 2008, Countrywide mailed about 122,000 homeowners a letter saying their home equity line was frozen. By May, Countrywide, Bank of America, Washington Mutual, and IndyMac had frozen roughly 600,000 lines between them, Chase had notified more than 150,000 customers that their lines were being cut or suspended, and lenders across the industry were doing the same in every market where prices were falling.

Over the next year the number of open home equity lines in America dropped by about 855,000, and roughly $68 billion of available credit disappeared. Most of those homeowners hadn’t missed a payment. A computer estimated that their house was worth less, and the fine print let the lender shut the line, which federal rules allow when a home’s value drops significantly.

Chase later settled a class action covering every customer whose line it had cut that way between 2007 and 2012, and agreed to stop relying on some of the computer valuations it had used. I know how those letters read. I got two of them, one for each house I owned at the time.

Now picture a family running velocity banking that spring. Their paycheck goes into the line. Their bills come out of the line. The $10,000 chunk they borrowed last month is still owed. And the letter arrives.

The line that was supposed to be their payoff engine and their emergency fund is gone in the same envelope, right as the economy heads into its worst year since the Depression. A home equity line is credit someone else can take back. Treating it as money you own is the mistake underneath the whole strategy.

I’ve made that mistake on a client’s behalf. Years before 2008 I set up a home equity line for one of my best clients, a small-business owner, and when she asked why she needed it I told her she didn’t, but it would come in handy on a rainy day.

When 2008 came she planned to make payroll from that line. The lender had frozen it. She nearly lost the business, and the line I’d called a rainy-day fund had turned out to be an umbrella someone else could take back.

What’s left

A garden hose delivers whatever the spigot gives it. You can buy a nicer nozzle, but the lawn gets the water the hose gets. Paying off debt faster works the same way: the water is your leftover cash each month, and the nozzle is the account structure. Velocity banking sells the nozzle. The webinar’s seven-year family just had the spigot open wider.

If you have money left over each month, that money is the lever. Send it to the right balance in the right order, refinance when the market hands you a lower rate, and treat your line of credit as what it is: a backup you don’t count on, not a payoff engine.

That’s the whole plan. It fits on a napkin, and it beat the five-spreadsheet system in every test case I could find.

The long version

DebtRetired doesn’t sell velocity banking or use it with clients. We tested it, and the full study is on our research page: every assumption, every chart, and the spreadsheet behind the numbers. It was written for financial advisors and accountants, so it runs long. You don’t need it to act on what’s here.
