Good Debt vs Bad Debt: The Distinction That Actually Matters
Not all debt is created equal — knowing the difference shapes every borrowing decision.
The simple framework
'Good' debt funds something that increases your future earning power or wealth (education, a home, a profitable business). 'Bad' debt funds something that depreciates or doesn't generate return (consumer goods, vacations on credit, depreciating cars). The distinction isn't moral — it's economic.
Mortgages
A reasonably-sized mortgage on a primary residence is the classic 'good' debt — fixed rate, tax-advantaged in many systems, building equity, and typically tracking inflation. A mortgage you can't comfortably afford is bad debt regardless of the asset.
Student loans
Education debt is good when it leads to a degree with strong income potential. It's catastrophic when it doesn't — a $100,000 art history degree from a private school has very different economics from a $30,000 nursing degree from a state school.
Business loans
Borrowing to start or grow a business that will produce income is reasonable when supported by realistic projections. Borrowing to chase a hobby is consumer debt with extra steps.
Bad debt to avoid
Credit card balances carried month to month, payday loans, auto loans on luxury vehicles you can't afford, financing furniture or electronics. These transfer wealth from you to lenders at high rates.
The rate matters
Even 'good debt' becomes bad at a high enough rate. A 12% mortgage is borderline disastrous; a 3% one is nearly free money. Always evaluate debt by the rate, the term, and the use combined.
Frequently asked questions
Is car debt always bad?
Modest debt on a reliable, affordable car for genuine transportation needs is closer to neutral than bad. Luxury upgrades on credit are clearly bad debt.
What about 0% promotional APR?
Useful if you can confirm repayment before the promo ends. Disastrous if you can't — back interest often applies retroactively.
Should I pay off all debt immediately?
Not necessarily — extremely low-rate debt may be worth keeping while you invest excess cash. Always pay off high-rate consumer debt first.
