Good debt vs bad debt
Not all borrowing is equal
Figures checked September 2026
India’s credit card dues went from about ₹340 crore in 2015 to roughly ₹2.88 lakh crore by August 2025, and about 45% of new cardholders are under 30. If that includes you, this is the lesson that pays for itself.
Debt isn’t always bad. Used well, borrowing can move your life forward years earlier than saving alone would. Used badly, it quietly drains you. The whole skill is telling the two apart before you sign.
What makes debt “good”
Good debt buys something that grows in value or earns you more over time, usually at a lower interest rate.
- A skill or education that raises what you can earn.
- A home loan, where you build an asset and the interest rate is relatively low.
- A sensible business loan that lets you earn more than it costs.
The test is simple. Does the borrowed money help you build or earn something worth more than the interest? If yes, the debt is working for you.
What makes debt “bad”
Bad debt pays for things that lose value fast, at high interest.
- A credit-card balance you don’t clear in full.
- “Buy now, pay later” on things you consume and forget.
- A personal loan for a lifestyle expense, like a holiday, a gadget, or a wedding splurge.
Here the money buys something that fades while the interest keeps climbing. The debt is working against you.
The cost ladder
Interest rates vary by lender and by your profile, but the ordering is remarkably stable. From cheapest to dearest, roughly: home loan, then loan against property, then education loan, then car loan, then personal loan, and finally credit-card revolving balances at the top.
The reason is security. A home loan is backed by the home, so the lender can recover something if you stop paying, and charges you less for that comfort. A credit card is backed by nothing at all, so it costs the most. That single idea explains most of the ladder.
The credit-card trap, in rupees
The classic bad debt is the credit card you only partly pay.
The rupee example. You spend ₹30,000 on a card and pay only the small “minimum due”. The unpaid balance can cost roughly 3% to 3.5% every month, which works out to about 36% to 42% a year, and is close to ₹900 to ₹1,050 in the first month alone, and it stacks on a balance that keeps growing.
Why the “minimum due” is the trap
The minimum due is designed to keep you comfortable and in debt. Pay only that, and most of your payment barely touches the balance, so the interest clock keeps running on almost the full amount. A ₹30,000 bill treated this way can quietly balloon into far more over a year.
There’s a second sting people miss. Once you carry a balance, many cards stop giving you the interest-free period on new purchases too. So the coffee you buy tomorrow starts accruing interest from day one.
The one habit that protects you
Treat a credit card like a debit card. Spend only what you can fully repay by the due date, and always pay the full statement amount, never just the minimum. Do that and a credit card is a convenient, even rewarding tool. Break it and it becomes the most expensive money you’ll ever borrow.
Compounding, working against you
You’ve seen how compounding grows your investments. Bad debt is that exact same math, pointed the other way. On a credit card, interest piles on interest on you. The snowball still rolls. It just rolls downhill toward the bank.
That’s why clearing high-interest debt is often the best “investment” you can make. Paying off a balance costing 40% a year is a guaranteed 40% saved, better than almost any return you could chase elsewhere.
Before you sign anything
Three questions worth answering honestly:
- What does this cost in total? Not the EMI, the full amount you’ll repay. A longer tenure lowers the EMI and raises the total.
- What’s the rate, and is it fixed or floating? A floating rate can move against you later.
- What are the extras? Processing fees, prepayment penalties, insurance bundled in. These rarely appear in the advertisement.
A rough guide on size: keep all your EMIs together under about 40% of take-home pay. Lenders use a similar test when they assess you. Past that point, one bad month starts forcing fresh borrowing, which is exactly how good debt turns bad.
Two ways to clear what you owe
When you’re juggling several debts at once, pick a method and stick to it.
The avalanche. Pay minimums everywhere, then throw everything spare at the highest interest rate. Mathematically this costs you the least.
The snowball. Pay minimums everywhere, then clear the smallest balance first. It costs slightly more, but closing an account early is a real motivator, and a plan you finish beats a cheaper one you abandon.
If the rates are close together, use the snowball. If one debt is far more expensive than the rest, use the avalanche.
A simple order of priority
When money is tight and you’re juggling both:
- Keep a small emergency cushion so you don’t add new debt.
- Clear the highest-interest debt first, usually cards and BNPL.
- Then invest steadily for the long term.
Common mistakes
- Paying the minimum due and believing the card is handled.
- Judging a loan by its EMI instead of its total cost.
- Stretching the tenure to afford a bigger purchase.
- Taking a new loan to pay an old one without cutting the rate.
- Ignoring the credit record, which quietly decides what you’ll be charged next time.
Not all borrowing is a mistake. But borrow for things that grow, avoid borrowing for things that fade, and never let a card balance roll. Get that right and debt becomes a tool instead of a trap.

Questions people ask
What actually makes a debt good or bad?
Two things: what the money buys, and what it costs. Borrowing cheaply for something that grows in value or raises your earnings is good debt. Borrowing expensively for something that fades is bad debt. A home loan usually passes both tests. A card balance fails both.
Should I clear debt or invest first?
Compare the interest rate to the return you could reasonably expect. Clearing a balance that costs 40 percent a year is a guaranteed 40 percent saved, which beats almost any investment. Low-cost debt like a home loan is different, and often worth carrying while you invest.
Why is paying the minimum due on a credit card so damaging?
Because it barely touches the balance. Most of the payment covers interest, so the clock keeps running on nearly the full amount. It's designed to feel affordable while keeping you borrowing, which is why a modest bill can balloon over a year.
What's the avalanche method versus the snowball method?
Avalanche means clearing the highest interest rate first, which costs you the least overall. Snowball means clearing the smallest balance first, which gives you a quick win and keeps you going. Avalanche is cheaper. Snowball is easier to stick to. Pick the one you'll finish.
How much EMI is too much?
A common rule of thumb is keeping all EMIs together under about 40 percent of take-home pay, and lenders look at something similar when they assess you. Past that, a single bad month starts forcing new borrowing. Treat it as a guide, not a law.
Does closing a credit card help my credit score?
Not always. Closing a card cuts your available limit, which can push up the share of credit you're using, and that share matters to your score. Clearing the balance helps. Closing the account is a separate decision with its own trade-offs.
Is a personal loan ever a good idea?
It can be, if it replaces something more expensive. Moving a credit-card balance to a cheaper personal loan reduces the interest while you clear it. Taking one for a holiday or a gadget is the textbook case of bad debt.
What's the difference between secured and unsecured debt?
Secured debt is backed by an asset, like a home or car, so the lender charges less because they can recover it. Unsecured debt, like cards and personal loans, has no such backing, so it costs more. That's most of why card interest is so high.
