Good Debt vs Bad Debt
Not All Debt Is the Same
Borrowing money is often treated as universally risky, but that's an oversimplification. Debt exists on a spectrum, and it's useful to think in terms of good debt and bad debt — a rough (not perfect) way to judge whether borrowing is likely to help or hurt in the long run.
What Makes Debt "Good"?
Good debt generally shares a few features:
- It's used for something likely to build future value or earning potential — like education, useful tools for work, or a productive investment
- The amount borrowed is realistic compared to what can actually be repaid
- The interest rate is reasonable, and the terms are well understood (see loans and interest)
What Makes Debt "Bad"?
Bad debt tends to share the opposite features:
- It funds something that loses value quickly, or provides no lasting benefit
- It carries a high interest rate, especially if it's likely to be carried for a long time
- The amount borrowed is not realistic compared to what can be repaid, creating ongoing financial strain
| Feature | Tends toward good debt | Tends toward bad debt |
|---|---|---|
| Purpose | Builds future value or skills | Funds something with fading value |
| Interest rate | Lower, manageable | High, expensive |
| Repayment plan | Realistic and affordable | Unclear or unrealistic |
| Example | A loan for relevant education or training | A high-interest balance from everyday impulse spending |
Worked Example — Two Loans
Imagine two people each borrow the same amount:
- Person A borrows to pay for a course that builds a skill likely to increase their future earning potential, at a manageable interest rate, with a realistic repayment plan.
- Person B borrows at a very high interest rate to fund a string of impulse purchases that lose most of their value almost immediately.
Person A's debt has a reasonable chance of "paying for itself" through improved future income. Person B's debt provides no lasting benefit and simply accumulates cost through interest — a textbook case of bad debt.
Even Good Debt Has Limits
It's worth remembering that labelling debt as "good" doesn't make it risk-free. Borrowing an unrealistic amount, even for a genuinely worthwhile reason, can still create serious financial strain if the repayments don't fit a realistic budget. The purpose of the debt matters, but so does the size of the debt relative to what can actually be afforded.
A Simple Framework for Judging Debt
Before borrowing, it helps to ask:
- What is this money for? Will it likely build value, or will the value fade quickly?
- What's the interest rate? Higher rates raise the bar for what counts as "worth it."
- Can I realistically repay this? Even a good reason to borrow can turn bad if repayment isn't realistic.
Key Words
- Good debt — borrowing likely to build future value or earning potential, on manageable terms
- Bad debt — borrowing for something that loses value quickly, often at a high cost
- Realistic repayment — a repayment plan that genuinely fits within what can be afforded
