How to Use a Credit Card Without Falling Into Debt — Expert Tips

Why Are Credit Cards Dangerous?

Credit card interest rates in Thailand are capped at 18% per year by the Bank of Thailand — much higher than personal loans. If you only pay the minimum of 5–8% of the outstanding balance each month, debt accumulates rapidly.

A Scary Credit Card Debt Example

Assume an outstanding balance of 50,000 THB, paying the minimum 2,500 THB/month (5%) at 18% annual interest — it will take over 3 years to pay off, with total interest paid exceeding 16,000 THB.

5 Rules for Safe Credit Card Use

1. Pay the full balance before the due date every month — the only way to pay zero interest
2. Keep your credit limit to 1–2 months of income — prevents overspending
3. Check your balance every week — catch problems before debt piles up
4. Avoid installment plans for non-essential items — 0% installments feel cheap but compress your monthly budget
5. Use a card that matches your spending habits — cashback if you shop online a lot, miles if you travel frequently

How to Make Your Credit Card Work for You

• Cashback: many cards return 0.5–2% on every purchase
• Points/Miles: redeem for free flights or rewards
• Free travel insurance: Platinum cards and above often include accident coverage
• 0% installments: use for necessary purchases you were going to make anyway — not because a promotion tempts you

If You Already Have Credit Card Debt

1. Stop using the card immediately
2. Transfer the balance to a lower-interest personal loan (Balance Transfer)
3. Contact your bank to request debt restructuring — BOT requires banks to maintain assistance programs for borrowers
4. Always pay more than the minimum to reduce principal, not just interest
