Is it worth getting a credit card? Pros, cons and who should avoid them
April 2026
Credit cards get a bad reputation because the people who use them badly talk loudly about it. But used correctly, a credit card is one of the best free financial tools available. The question is whether "used correctly" describes you.
The real benefits
- Cashback or points on spending you'd do anyway (typically 1–5%)
- Builds credit history, which reduces interest rates on mortgages and car loans
- Purchase protection and extended warranties (often free)
- Zero liability on fraudulent charges vs debit cards where banks take longer to investigate
- Float — you spend now, pay in 30 days (0% interest if paid in full)
The real risks
- Average credit card APR is 21–24% — the worst mainstream interest rate available
- Minimum payments are designed to maximise interest paid, not help you get out of debt
- Research consistently shows people spend 10–15% more when paying by card vs cash
- Annual fees on premium cards often exceed the value of rewards for average spenders
- One missed payment damages credit scores significantly
✅ The one rule that makes credit cards worthwhile
Pay the full balance every month, every time, without exception. If you do this, the APR is irrelevant, you get all the rewards and build credit for free. If you can't guarantee this, the risks outweigh the benefits.
Who should get one
- Anyone who pays in full monthly and wants free cashback on existing spending
- People building credit history for a future mortgage (use it for one small recurring bill)
- Frequent travellers (travel cards offer airport lounge access, no foreign transaction fees)
- Anyone who shops online frequently — chargeback protection is genuinely valuable
Who should avoid them
- Anyone who has carried a balance before and paid interest
- People who find tracking spending stressful or who budget tightly
- Anyone with current high-interest debt — paying off existing debt gives a guaranteed 20%+ return
- People who make most purchases as impulse buys
Our verdict
Worth it for disciplined spenders who pay in full monthly — the cashback and protections are genuinely valuable at zero cost. Not worth it for anyone who has ever paid credit card interest or suspects they might. A debit card with a rewards checking account is a better fit for most people.
