Good Debt vs. Bad Debt
Reviewed and updated
Not all debt is equal — one kind builds your future, the other drains it.
Overview
Debt is borrowed money you repay over time, usually with interest added on top. People often treat all debt as equally bad, but it helps to split it into two kinds: debt that can build your future, and debt that mainly funds spending today.
Knowing the difference between the two changes how you borrow for the rest of your life.
Core Concept
"Good" debt tends to fund something that grows in value or boosts your income — like a mortgage on a home or a loan for education or a business. "Bad" debt usually funds things that lose value or are quickly consumed, often at high interest, like a credit card balance for a holiday.
This matters because the same word, "debt", hides two very different deals. One can be a tool; the other is usually a trap.
Applied Insight
Compare two 5,000 GBP debts. One is a low-interest loan for a course that lifts your earning power for decades. The other is a credit card balance at 25% for a holiday that is over in a week.
Same amount, opposite effects. The first can pay for itself many times over; the second costs you extra every month for a memory. The question is always what the borrowing is buying.
Practical Walkthrough
The mistake is focusing only on whether you can make the monthly payment, rather than what the debt is for. Affordable bad debt is still bad debt.
Before borrowing, ask two questions: will this purchase still have value after the loan is repaid, and what is the interest rate? High-interest borrowing for something that will be gone or worthless is the pattern to avoid.
Key Takeaways
Debt is borrowed money repaid with interest.
Good debt funds things that grow in value or income.
Bad debt funds things that lose value, often at high interest.
Judge debt by what it buys and its interest rate, not just the monthly payment.
Next Steps
Look at any debts you currently hold and label each one "good" or "bad" based on what it funded and its interest rate, to see clearly where your borrowing really stands and what to tackle first.
