The Durability of Your Dollars

My youngest daughter got $20 recently for doing some farm chores.

Within the hour, $13.15 of it was a Black Rock drink.

Nothing wrong with that. She’s a kid after all. But it was gone in 20 minutes or less.

But watching her spend it got me thinking. She's a kid. She had every right to enjoy it without a framework. Most adults don't have one either.

This piece is that framework.

It starts with a $13 drink. But it scales all the way up to the biggest financial decisions you will ever make.

A quick preface before we get into it.

I am not going to tell you to stop buying coffee.

You are going to spend money on groceries, date nights, vacations, cars, and a hundred other things that do not compound or appreciate. That is not a problem. That is a life well lived. Nothing in this piece argues against any of it.

What I am asking you to look at is the mix.

Most people evaluate spending one purchase at a time. Can I afford this? Does it fit the budget? Those are reasonable questions, but they are narrow ones. They tell you almost nothing about the full picture.

The better question is not whether you can afford the next purchase. It is this: when I look at a full month, a full year, where does the weight of my spending actually live? How much of it is gone the moment it lands? How much of it is building something?

Most people have never asked that question. Not because they are careless. Because nobody ever gave them a framework for it.

This is that framework.

It does not ask you to give up any category. It asks you to see the categories clearly. Most people find that once the picture comes into focus, a few intentional shifts change the math more than they expected.

It starts with a $12 drink and a Greenlight notification. But the principle scales to every financial decision you will ever make.

The money is gone before the receipt prints.

The Black Rock drink is a perfect example. Groceries on a credit card you don't pay off. Concert tickets. A bar tab that became a balance. Subscriptions you forgot you had. Clothes worn once.

The moment the transaction is done, the value is gone. Nothing left. No asset, no lasting return.

When you borrow to pay for consumables, you are paying interest on something that no longer exists. You are paying tomorrow for something already gone today.

Most people do not think of it this way. They see the monthly payment, not the fact that what they bought is long since consumed.

This is the most expensive end of the spectrum. Not because it is wrong to spend here. But because the math never works in your favor when this is where most of your money lives.

Real value. But it fades.

Vacations. Weekend trips. The honeymoon. A great dinner for a milestone birthday. Season tickets. A concert you planned for months.

This one deserves a real conversation because shared experiences have genuine value. Time with people you love creates something real. There is a legitimate argument that the memory of a trip matters more than the price tag.

But from a financial lens, the value is short-lived. A week in the mountains is a week in the mountains. Then it is a photo on your phone and a balance on your statement. The experience does not compound. It does not appreciate.

This does not mean never take vacations. It means be clear-eyed about what you are financing. If you are still paying for last summer's trip when next summer arrives, you are borrowing against something already in the past.

The asset is real. But it is losing value.

Car loans live here. So do boat loans, RV financing, electronics purchased on credit, furniture packages, and equipment that wears out.

The asset exists. You can see it, drive it, use it. But from the moment you sign, it is worth less than you paid. Every year, the value falls. And if the interest is compounding faster than the asset is useful, you end up owing more than it is worth before you have finished paying.

Car debt is not inherently wrong. Transportation is a real need. But people underestimate how quickly auto loan interest stacks up, and how fast the car stops being worth what they owe.

The question at this tier is always the same: am I paying more for this asset over time than the value it delivers?

The debt funds something that can grow.

A mortgage on a property that builds equity. A loan to invest in your business. Borrowing to acquire an income-producing asset. Financing equipment that generates revenue. Using margin to acquire something with long-term value.

Here is where leverage starts to make sense.

The debt funds something that can grow. The asset works. The value can compound. If you structure it right, the return on the asset outpaces the cost of the debt.

This is why financially sophisticated people are not afraid of debt. They are afraid of the wrong kind. A business owner who borrows to expand capacity and grows revenue by 30 percent made a good trade. A consumer who borrows to finance a vacation they cannot afford made a bad one.

The debt looked identical on paper. The outcome was completely different.

The only question that matters.

The question is not whether you spend at every tier. You will. Everyone does.

The question is what your bank statement tells you when you look at a full month.

If most of it is Tier 1 and Tier 2, you are financing things that are already gone. That is not a character flaw. It is just a math problem. And math problems have solutions.

Start there. Look at the mix. If it bothers you, change one thing. Not everything. Just one thing.

My daughter will eventually look at her bank statement and ask that question herself. That is the whole goal.
