Understanding the Credit Card Loan Interest Trap
Many borrowers receive offers such as:
- Instant loan on your credit card
- Interest starting from 11%
- Zero convenience fee
While these offers appear attractive, the real borrowing cost is often higher. This situation is commonly referred to as the credit card loan interest trap, where the advertised rate looks low but the effective APR becomes significantly higher.
