The Debt Paradox

Here's something that might surprise you: not all debt is bad. In fact, some debt can actually help you build wealth. The trick is knowing the difference between debt that works for you and debt that works against you.

Think of debt like a tool. A hammer is useful for building a house, but useless for cooking dinner. Similarly, debt can be a powerful wealth-building tool in the right situation, but destructive in the wrong one.

What Makes Debt "Good"?

Good debt generally has these characteristics:

  • It helps you build assets or increase income — The money borrowed is invested in something that grows in value or generates income over time
  • It has a reasonable interest rate — You're not paying an exorbitant rate compared to what you're earning
  • There's a clear end date — You have a structured repayment plan that will eventually pay it off
  • The returns outpace the costs — What you gain is worth more than what you're paying in interest

Common examples of good debt include:

  • Home loans — You're borrowing to buy an asset (property) that typically appreciates over time. In Australia, property has historically been a solid long-term investment, and the interest rates are relatively low compared to other loans
  • Investment loans — Borrowing to invest in shares or managed funds. If your investment returns exceed the loan interest (say, 5–7% returns on a 4% loan), you're making money
  • Education loans (HECS-HELP) — You're investing in your earning potential. A degree or qualification typically increases your income over your lifetime, making the loan worthwhile
  • Business loans — Used to start or expand a business that generates income

What Makes Debt "Bad"?

Bad debt typically has these characteristics:

  • It's used to buy things that depreciate — The item loses value immediately or quickly
  • It has high interest rates — You're paying substantially more than the item is worth
  • It doesn't generate income or growth — The money borrowed doesn't help you earn or build wealth
  • It's easy to accumulate quickly — You can spiral into owing more than you can manage

Common examples of bad debt include:

  • Credit card debt — With interest rates often 15–20% or higher, credit cards are one of the most expensive ways to borrow. If you're only making minimum payments, you're mostly paying interest
  • Personal loans for consumables — Borrowing to buy a new car, holiday, or furniture that you'll enjoy but won't make you money
  • Buy-now-pay-later (BNPL) services — Easy to use but can trap you in a cycle of spending you can't afford
  • Payday loans — These are predatory. The interest rates can exceed 200% per year

The Real-World Australian Angle

In Australia, we have a cultural affinity with property investment and home ownership. A home loan is generally considered good debt because:

  • The interest rate is lower than most other loans (currently around 4–6%)
  • Property has historically appreciated over time
  • You're building equity — each payment is money in your pocket, not a bank's
  • It's tax-deductible if it's an investment property

However, borrowing for a car (unless it's for a business purpose) or overspending on credit cards is bad debt because you're paying high interest rates for something that depreciates.

The Grey Area

Some debt sits in the middle. A car loan, for example, can be good if you use the car to earn income (say, for a delivery business), but bad if you're using it purely for personal use and paying 6–8% interest on a depreciating asset.

The key question to ask yourself: Will this debt help me earn more or own more in the future?

What Should You Do?

  • Prioritise paying off bad debt first — High-interest debt is the enemy. Focus on credit cards and personal loans before other debts
  • Don't avoid good debt — If you're saving for a home or investing in your education, strategic borrowing can accelerate your wealth-building
  • Check the numbers — Before taking on any debt, calculate whether the returns justify the cost
  • Have a plan — Whether it's good or bad debt, make sure you can afford the repayments without stretching yourself thin

Debt isn't inherently evil, but it's powerful. Use it wisely, and it becomes a stepping stone to wealth. Use it carelessly, and it becomes an anchor holding you back.
