Not all debt is equal. Some borrowing can help you build skills, assets, or income, while other borrowing drains your finances for years. The difference depends on what you buy, the cost of the loan, and whether you can comfortably repay it. This guide offers a practical framework for deciding when debt makes sense.
What people mean by good debt "Good debt" usually describes borrowing that funds something likely to increase your net worth or income over time. Examples can include:
- A reasonable mortgage on a home you can afford.
- Education or training that meaningfully improves earning potential.
- A business loan backed by a realistic plan.
- A reliable vehicle needed to earn income, bought at a sensible price.
Even good debt can become harmful if the amount is too large or the terms are poor.
What people mean by bad debt "Bad debt" generally funds consumption or depreciating items at high interest rates. Examples include:
- Credit card balances carried month to month.
- High-cost payday or short-term loans.
- Financing holidays, gadgets, or luxury items.
- Buy-now-pay-later plans used for everyday spending.
These debts cost money without building future value.
Five questions to ask before borrowing 1. Will this purchase increase my income or net worth over time? 2. What is the APR and total cost of borrowing? 3. Can I comfortably afford the payment from net income? 4. What happens if my income falls? 5. Could I save for this instead?
Use the loan calculator to find the total repaid. Seeing that a $3,000 purchase costs $3,800 over time often changes the decision.
