Debt as a Tool: How Leverage Actually Builds Wealth

Over the last few weeks, we’ve climbed through this debt series together. You learned to spot when debt crosses from tool to trouble. You learned the difference between good debt and bad debt. Today we finish the climb by looking at something most people never get taught: how debt, used on purpose, actually builds wealth. There’s a word for that. It’s called leverage.

I sat across from a lot of families in my advisor years who flinched at the word “debt” — or “leverage,” once they learned it meant the same thing. That’s not an accident. A lot of us were taught, sometimes loudly, that all debt is dangerous. But debt used to grow your own wealth has a name, and it isn’t a bad word. It’s leverage.

Once you understand it, you’ll never look at a mortgage statement the same way again.

What Leverage Actually Means

Leverage is borrowing money to acquire something that grows in value or produces income, using a relatively small amount of your own cash to control something bigger.

Here’s the plain-English version: you put down $40,000 on a $400,000 house. The bank puts up the other $360,000. If that house appreciates 3% next year, you don’t just gain 3% on your $40,000 — you gain 3% on the full $400,000. That’s leverage working for you.

The same idea shows up in a business loan that lets someone buy equipment that pays for itself in revenue, or a student loan that unlocks a career earning far more than the debt cost. In every case, the debt is a tool that lets you control something bigger than your cash alone could buy.

Where You’ve Probably Already Used It

You don’t need to be an investor to have used leverage. Most Ascenders already have.

• Your mortgage. If your home has appreciated since you bought it, leverage already worked in your favor — even if you never thought of it that way.
• A business loan for equipment or inventory that generates more revenue than it costs. The debt pays for itself and then some.
• Student loans tied to a real career outcome. If the degree led to income that outpaces the loan, that’s leverage doing its job.

Notice the pattern. In every good example, the debt is attached to something that either grows in value or grows your income. That’s the test.

Debt Isn’t Bad Every Time — Here’s the Proof

I recently came across a number that surprised even me: roughly 1 in 4 homeowners with a mortgage rate around 3% are paying extra toward that mortgage every month.

I get the instinct. Money isn’t just math — it’s emotional. Debt especially carries weight that a spreadsheet can’t capture. Paying it off feels like relief, like control, like proof you’re doing the right thing. That feeling is real, and it matters. But mathematically, paying extra on a 3% mortgage is often the wrong move.

If your mortgage is costing you 3% and the stock market has historically returned 10% or more over time, every extra dollar you send to the mortgage is a dollar that could have earned the spread — the difference between what you’re paying and what you could be earning.

That’s not a guarantee, and the market doesn’t move in a straight line. But it’s the clearest example of why debt isn’t automatically the enemy. A cheap mortgage sitting quietly in the background while your money grows elsewhere is leverage doing exactly what it’s supposed to do.

So Where’s the Line?

A few weeks ago, we talked about a 10% threshold as a rough way to flag debt that’s becoming a problem. I want to be careful with that number today, because it’s a guide, not a rulebook. A 9% loan isn’t automatically fine, and an 11% loan isn’t automatically a disaster. The real question is bigger than any single percentage:

Is this debt helping you climb toward your summit — or is it just weighing down your pack?

A mortgage on a home you can afford, at a rate lower than what your money could earn elsewhere, is leverage. A loan for something that doesn’t grow, doesn’t produce income, and stretches your monthly budget thin is a liability wearing a leverage costume. The rate matters. But what the debt is doing for you matters more.

Now What?

You don’t need to take out new debt this week. You just need to see the debt you already have with clearer eyes.

1. Pull out your list from the last two weeks — the one where you labeled each debt good, bad, or straining.
2. For every “good” debt, ask: is this attached to something growing? A home, an education, an income-producing asset.
3. If yes, you’re not carrying debt. You’re using leverage. Let it keep working quietly in the background.
4. If a “good” debt isn’t actually attached to growth, relabel it honestly. That’s useful information, not a failure.

That’s the whole series in one sentence: debt without the purpose of helping you grow toward your summit is just weight. Debt with a purpose is a tool.
