The dangerous thing about using credit cards is that if you don’t use them carefully, you can wind up neck-deep in debt — and getting out of that debt will cost you dearly. If you’re paying off a $10,000 balance over two years, and your APR is 18%, then you can expect to pay about $2,000 in interest. However, a 0% introductory APR balance-transfer credit card can grant you a reprieve from interest lasting anywhere from 12 to 21 months. During that period, all your payments will go straight to the principal amount owed, allowing you to pay off that debt a lot faster. There are instances when applying for a balance-transfer credit card might not make sense. Look for these reasons in part 2 tomorrow.
