Good Debt vs Bad Debt — What's the Difference?
Most people are taught that all debt is bad. The reality is more nuanced. Some debt builds your future. Some debt destroys it. Knowing the difference changes how you make financial decisions.
Key takeaways
Good debt — it builds value
Good debt is borrowed money that helps you acquire something that grows in value or increases your earning potential. A home loan at 9% to buy a flat that appreciates over time — you are building an asset while living in it. An education loan that takes your salary from ₹25,000 to ₹65,000 per month — the loan cost ₹8 lakhs, but the return in earning power over a career is many times that. A business loan to buy better equipment that doubles your production and profit — it paid for itself and keeps giving returns.
Bad debt — it destroys value
Bad debt is borrowed money spent on things that lose value immediately or provide no lasting return. Credit card debt is the most dangerous. Ajay buys a ₹45,000 phone on a credit card and pays only the minimum due each month. Credit card interest in India runs between 36% and 42% per year. By the time he pays it off over 12 months, that ₹45,000 phone has cost him over ₹60,000. He paid ₹15,000 extra for the privilege of buying it on credit.
More examples of bad debt
A personal loan at 14-18% interest to fund a vacation. The holiday is over in a week. The EMIs last two years. You are paying for an experience long after it has ended. Buy Now Pay Later for gadgets and clothes — BNPL services make it dangerously easy to spend money you do not have. The amounts seem small individually — ₹2,000 here, ₹3,500 there — but they add up quickly into debt that eats your monthly cash flow.
The grey area — car loans
A car loan sits in the middle. A car depreciates — it loses value every year. But if the car enables you to get to work, earn income, and save two hours of commuting daily, it has practical value even if not financial appreciation. In this case, borrow the minimum, choose a shorter loan tenure, and avoid premium models beyond your means just for status.
One simple question before borrowing
Ask yourself: will this loan help me earn more, build something, or genuinely improve my life in a lasting way? If yes, it may be good debt worth considering. If you are borrowing for a lifestyle upgrade, convenience, or simply because you want something now and cannot wait — that is bad debt. The cost of impatience is the interest you pay.
