I consider myself fairly well educated about the "tricks" that credit card companies play. But today, I learned, through personal experience, of yet another one.
You all probably know, as do I, that if you take a cash advance on a credit card, it is subjected to a higher interest rate. You probably also know, as do I, that payments you send in are applied to your purchases balance (at a lower interest rate, usually); none of the payment you send in reduces your cash advance principal balance until the purchases balance is paid down in full.
Here's what I didn't know, but discovered today while giving a closed account we're paying off a good eyeball.
The portion of the bill subject to cash advance charges was $1300 or so. This surprised me--we NEVER take cash advances on our cards, based on the knowledge from the points mentioned above.
I called the bank to find out when we ever took a $1300 cash advance.
Turns out, we never did. However, in July 2004 we did open the card, at a zero-percent rate for 12 months on all balance transfers, and we transferred a $420 balance to this card and closed the other. Using the card for a business we were running, and not paying off the balance in full each month, we didn't pay off the balance transfer during the promo period. "It" became classified as a "cash advance" subject to the higher interest rate.
Here's the part that surprised me... no, shocked me! The INTEREST on that amount doesn't get paid off with my monthly payments, either, but has ACCRUED DAILY and been ADDED ONTO the "cash advance" balance, changing the original $420 transfer into a $1300 cash advance balance, still subject to the higher rate (every day).
I've just reprioritized which of my debts get paid off out of next month's bonus.
Posting this here as a consumer education tip. I was caught off guard by the growth of the cash advance amount (I never took "cash" from an ATM with this card) via the accrual of the higher-rate interest on that amount... it happened slowly, month by month, and though an avid watcher of statements and tracker of balances / rates, I missed it on this card.
