Good debt vs bad debt
Not all borrowing is equal
Debt is not always bad. The trick is knowing the difference.
Good debt buys something that grows in value or earns you more later, like a skill, an education, sometimes a home. The cost is usually lower and it can pay off.
Bad debt pays for things that lose value fast, at very high interest. The classic example is a credit card balance you do not clear in full.
The rupee example. You spend ₹30,000 on a card and pay only the small minimum due. The unpaid amount can cost roughly 3% to 3.5% every month, close to ₹900 to ₹1,050 in the first month alone, and it keeps stacking on a bigger balance. That is how a ₹30,000 bill quietly becomes much more.
The 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 amount, never just the minimum.
This is general education, not financial advice. Interest rates vary by card and bank, check your own terms.
