Good Debt vs Bad Debt

Not all debt is created equal. Some can build your future; some quietly drains it. Here's how to tell which is which.

The simple test

Ask one question: does this debt buy something that grows in value or income — or something that loses value?

• Good debt tends to fund an asset or higher future earnings, at a reasonable interest rate.
• Bad debt funds consumption that loses value, usually at a high interest rate.

Examples of "good" debt

• A mortgage — buys an asset that can appreciate and builds equity instead of rent. Run the numbers on the mortgage calculator.
• Student loans (in moderation) — can raise lifetime earnings, though the amount matters; see the student loan calculator.
• A business loan that generates more income than it costs.

Examples of "bad" debt

• Credit card balances — often 20%+ APR on things that lose value. The most urgent to eliminate; use the debt payoff calculator.
• Financing depreciating toys — high-interest loans on gadgets or an overpriced car.
• Payday loans — extremely high cost; avoid entirely.

The nuance: rate and discipline matter

Even "good" debt turns bad if the rate is too high or the payment strains your budget. And "bad" debt categories can be fine if paid off in full each month (like a rewards card you never carry a balance on). The rate, the term, and your discipline decide more than the label.

How it fits your bigger picture

Every debt is a liability on your net worth. The goal isn't zero debt at all costs — it's making sure the debt you carry is working for you, not against you. Kill high-interest "bad" debt first, keep reasonable "good" debt manageable, and invest the difference.
