Revolving Interest Trap
1. As long as you don't pay in full, all purchases accrue interest from the posting date, not from the payment due date.
2. Minimum payments seem easy, but most of the payment goes to interest, and the principal decreases very slowly.
3. New purchases are immediately added to revolving interest calculations, creating a staggering compound interest effect.
4. An annual rate of 15% means unpaid balances double every 5 years.
Suggestion: Make it a habit to pay in full monthly. If that's difficult, consider a personal loan to refinance at a lower rate.
