Should I use a credit card or is it a debt trap?

Both are right about different people. A credit card paid in full every month is a free short-term loan with rewards and protections. A card carrying a balance is one of the most expensive forms of borrowing available. The card is neutral; the behaviour determines everything. **The genuine benefits when used properly:** 1. **Building credit history**, which affects your ability to get a home loan later and the rate you'll pay. This is the strongest practical argument for having one. 2. **Purchase protection and dispute rights.** If a merchant defrauds you or goods don't arrive, a chargeback is far more effective than trying to recover a debit transfer. 3. **Fraud liability.** Card fraud is the bank's money until resolved; debit card fraud is your money until refunded, which matters enormously if rent is due. 4. **Interest-free float** of up to about 45-50 days. 5. **Rewards** — cashback or points, worth 1-2% of spending, which is real money on expenses you'd have anyway. **The genuine dangers:** - **Interest of 30-45% annually** on carried balances, compounded monthly. This is the trap, and it's severe. - **Minimum payments are designed to keep you in debt.** Paying the minimum on a large balance can take over a decade and cost more in interest than the original purchase. - **Spending psychology.** Research consistently finds people spend more with cards than cash, because the pain of payment is deferred and abstract. - **Cash advances**, which typically charge interest from day one with no grace period, plus a fee. **The rules that make it safe:** 1. **Pay the full statement balance every month, automatically.** Set up autopay for the full amount, not the minimum. This single setting is what separates the two outcomes. 2. **Treat the limit as irrelevant.** Spend only what's in your bank account. 3. **Never take a cash advance.** 4. **Keep utilisation below 30%** of the limit for credit score purposes. 5. **Avoid EMI conversions** on purchases unless the interest is genuinely zero and you've checked for processing fees. **Who should genuinely avoid one**: anyone who has struggled with impulse spending and hasn't yet built a system for it. If you know a card would be used as extra money rather than a payment method, your parents are right about you specifically — and a debit card plus building credit another way is the safer path.
