Good Debt vs. Bad Debt: Distinguish to Use Leverage for Wealth Building Instead of Drowning in Debt

In Vietnam, many people grow up with the belief that "debt is bad and should be avoided at all costs." While this mindset protects many from trouble, it also causes quite a few to miss opportunities — because the truth is there are debts that make you wealthier, and debts that drag you down. Knowing how to distinguish between these two is a crucial financial skill.

What is Good Debt?

Good debt is a loan that helps you create or increase value beyond the borrowing cost. Characteristics:

• Used to purchase assets capable of generating income or appreciating over time.
• Or invested in something that enhances your earning capacity.
• Reasonable interest rate, and repayments are within your means.

Examples of debt that can be "good":

• Mortgage for a home to live in (instead of long-term renting), when you can afford the payments.
• Business loans for operations with clear cash flow and profit.
• Student loans for education and skills that increase income.

Common thread: this loan helps your net worth increase over time.

What is Bad Debt?

Bad debt is a loan used to buy things that depreciate or only serve consumption, often with high interest rates. Characteristics:

• Used to buy consumer goods (depreciate over time) or immediate spending.
• High interest rates (overdue credit cards, quick consumer loans, loan sharks).
• Doesn't generate income or value to offset the cost.

Examples:

• High-interest loans to buy the latest phone, luxury items, or travel.
• Installment payments on multiple consumer items simultaneously beyond your means.
• Daily-interest loan shark debt.

Bad debt causes your net worth to gradually decrease — you're paying money to become poorer.

The Line Isn't Always Clear

The same loan can be good or bad depending on circumstances:

• A mortgage is good debt if you can afford payments; but becomes bad debt if you overborrow and become financially exhausted.
• A business loan is good debt if the operation is profitable; becomes bad debt if poured into unprofitable ventures.

So the question isn't just "what am I borrowing for," but also "can I afford to repay it, and does this create value exceeding the borrowing cost?"

Principles for Using Leverage Safely

Leverage (borrowing to amplify results) is a double-edged sword — it multiplies both gains and losses. To use it safely:

1. Only borrow for value-creating purposes, don't borrow for emotional consumption.
2. Keep debt-to-income ratio within safe limits (total monthly debt payments should typically be under 35–40% of income).
3. Always have an emergency fund before borrowing — so you don't default when income is interrupted.
4. Prioritize paying off high-interest debt first (see article on debt repayment strategies).
5. Read the actual interest rate and total borrowing costs carefully, not just the advertised numbers (see article on understanding interest rates).

Warning Signs You're Borrowing Beyond Your Means

Be alert if:

• Monthly debt payments consume most of your income.
• You have to borrow new loans to pay old ones.
• You can only make minimum payments on credit cards.
• Nothing left to save after debt payments.
• Stressed, losing sleep over debt.

If you notice many of these signs, your number one priority should be reducing debt, temporarily setting aside other goals.
