The smart way to think about debt

The smart way to think about debt

June 28, 2025

Welcome to the fifth issue of Metrix that Matter, a weekly newsletter from WEALTHMETRIX that helps you focus on what matters most for building and sustaining wealth. Every Saturday, we share an educational essay with actionable takeaways to guide you on your journey to financial independence.

A lot of people like to speak in absolute truths. It makes life easier to manage.

Good or bad. True or false. Right or wrong.

Decisions are easier if we can filter everything through a simple lens.

Take nutrition, for example. Depending on who you ask, carbs, fat, and cholesterol can be good or bad.

The same oversimplification happens with exercise. Strength training and cardio draw differing opinions from fitness experts.

Even technology falls into this trap. Ask parents about kids’ screen time and you’ll get passionate arguments on both sides.

In reality, quality and quantity matter far more than the black-and-white labels we love to assign.

This is especially true when it comes to debt.

The most polarizing topic in personal finance

If you spend any time discussing personal finance, you'll quickly discover that debt might be the most polarizing topic of all.

On one side, you have the camp that believes all debt is bad, you should pay off your mortgage early, and borrowing money is a path to financial ruin.

On the other side, you hear that "debt is a tool" and "the rich use leverage to build wealth." Real estate investors talk about using other people's money to buy properties. Business owners leverage debt to grow their companies faster.

Both sides have compelling stories and real-world examples to back up their claims.

The truth? Debt is a double-edged sword, and leverage cuts both ways.

When you borrow money to buy assets that appreciate in value, debt amplifies your gains.

Buy a house with just a 20% down payment, and you benefit from the appreciation on 100% of the home's value. That's the power of leverage working in your favor.

But when that same house loses value, debt amplifies your losses.

This is the nature of leverage: it magnifies whatever happens next, good or bad.

As with nutrition and exercise, quality and quantity matter far more than ideology when it comes to debt.

The quality question: good vs. bad debt

Let’s start with quality. Not all debt is created equal. Understanding the difference between good debt and bad debt is crucial for making smart financial decisions.

Good debt typically has three characteristics: it helps you acquire an asset that has appreciation potential, offers the ability to generate income, and/or comes with relatively low interest rates compared to the value it provides.

Think mortgages on real estate, student loans for valuable education, or business loans that provide ways of generating additional income. These debts can improve your financial position over time. A mortgage allows you to build equity in property that may appreciate. Student loans can lead to higher lifetime earnings. Business debt can create cash flow that exceeds the cost of borrowing.

Bad debt, on the other hand, is used to purchase consumption that provides no lasting value or depreciating assets. Credit card debt is the ultimate example, as most of these purchases provide no financial value. On top of that, the debt that accrues can quickly spiral out of control with extremely high interest rates. Auto loans occupy a gray area, as transportation is often necessary, but vehicles are typically depreciating assets.

The key distinction is how the debt affects your overall financial trajectory. Good debt has the potential to make you wealthier over time, while bad debt does the opposite.

Here's a simple test: if you removed the item you borrowed money for, would you be in a better or worse financial position? A house or education likely makes you better off. A maxed-out credit card from impulse purchases doesn't.

The quantity question: healthy ranges for debt

Even good debt can become problematic if you take on too much of it. This is where quantity matters as much as quality.

Here are some general guidelines for debt ratios based on the percentage of your gross income going toward debt payments:

  • Low (10-15%): You have significant flexibility in your cash flow and greater ability to weather financial storms
  • Average (20-30%): You're in a manageable range but should be mindful of taking on additional debt
  • High (40%+): Your debt payments are consuming a large portion of your income, limiting your financial options

The CERTIFIED FINANCIAL PLANNER® Board offers additional guidelines that focus on specific types of debt:

  • Mortgage payments (including principal, interest, taxes, insurance, and HOA fees) should not exceed 28% of your gross monthly income
  • Total debt payments (including housing, auto loans, student loans, credit cards) should stay below 36% of your gross monthly income

In my experience working with clients, the families who are able to save the most consistently are the ones who keep their debt rate under 25% of their gross income.

But remember, these are guidelines, not rules carved in stone. Your personal situation and the tradeoffs you are willing to make matter.

What’s important is ensuring your debt payments don't force you to cut back on spending priorities or hinder your savings goals.

Climbing out of debt

If you find yourself with more debt than you'd like, especially the bad kind, the good news is there are proven strategies to climb your way out.

Debt Snowball Method

List all your debts from smallest balance to largest, regardless of interest rate. Pay minimums on everything, then throw every extra dollar at the smallest debt until it's gone. Once eliminated, roll that payment into the next smallest debt. This method builds momentum and psychological wins that keep you motivated.

Debt Avalanche Method

List debts from highest interest rate to lowest. Pay minimums on everything, then attack the highest-rate debt first. Mathematically, this saves the most money over time. It's the optimal choice if you can stay motivated without the quick wins of the snowball approach.

Refinancing and Consolidation

Sometimes you can improve your situation by restructuring existing debt. Refinancing a mortgage at a lower rate, consolidating high-interest credit cards into a personal loan, or transferring balances to a 0% promotional card can reduce your monthly payments or total interest paid.

Strategic Liquidation

In extreme cases, it might make sense to sell investments to pay off high-interest debt. If you're earning 7% in the market but paying 22% on credit cards, the math is clear. This should be a last resort, especially if you are pulling money from a qualified account where you will owe taxes and penalties. But sometimes stopping the bleeding within your cash flow is the only way to move forward.

No matter which strategy you choose, it’s important to create a plan first. It takes long-term commitment to get yourself out of debt. Pick your strategy, automate what you can, and celebrate the small victories along the way.

Finding your balance

Ultimately, debt doesn't have to be your enemy, but you need to manage it responsibly.

Like the nutrition and exercise examples we started with, the answers are found in understanding that both quality and quantity matter, and that your individual situation determines what's right for you.

The family using a mortgage to buy their first home is making a very different choice than someone maxing out credit cards for lifestyle purchases. The business owner leveraging debt to expand operations is making a very different choice than someone looking to finance their next car.

When it comes to debt, you need to ensure that the payments are manageable and give you enough savings capacity to move toward your financial goals. No matter how "good" your debt might be, you still need to save for emergencies, invest for retirement, and maintain the cash flow flexibility that creates true financial security.

Using debt as a carefully calibrated tool, with full awareness of both its power and its risks, is the nuanced approach that separates financial success from financial stress. 

WHAT TO FOCUS ON THIS WEEK

Calculate your current Debt Rate. Add up all your monthly debt payments (mortgage, auto loans, student loans, credit cards) and divide by your gross monthly income.

Next, categorize each debt as "good" or "bad" using the quality test: Does this debt help you build wealth or earn income? Or is it consuming your cash flow for items that provide no lasting value?

For your "bad" debt, choose your elimination strategy:

  • Eliminate debts by balance (smallest to largest) if you need psychological wins to stay motivated
  • Eliminate debts by interest rate (highest to lowest) if you want to minimize total interest paid

If your total Debt Rate is above 30%, identify one specific action you can take this month to begin improving it. This might be:

  • Making an extra payment toward your highest-interest debt
  • Researching refinancing options for your mortgage or auto loan
  • Setting up automatic transfers to accelerate debt payoff
  • Avoiding new debt while you focus on elimination
