Dear Liz: I’m 27 and have no consumer debt, a decent salary and a boatload of student loans. I use my credit cards for most of my expenses to earn rewards points and generally pay off my cards each month. I also take advantage of the 0% introductory rate offered by many credit card companies. This grace period gives me a security blanket so that I can spread large expenses such as insurance or car repairs over several months without derailing my saving plans. Can I apply for these offers without wrecking my excellent scores?
Answer: Occasionally applying for a new card won’t affect your scores much. Typically such applications ding your scores by five points or less.
You should be budgeting and saving for large expenses, however, rather than leaning on your cards. (Car repairs, in particular, aren’t really “emergency” costs — if you have a car, you know they’re coming, and calculators like Edmunds.com’s “True Cost to Own” feature can give you a good idea of what they’re likely to be.) Those 0% offers often come with balance transfer fees or other charges that make the deals a lot less attractive than they seem at first glance.
Also, you should be in the habit of always paying your cards in full — always. “Generally” isn’t good enough, since you could easily be enticed into spending beyond your means, especially as you chase rewards points. Rewards cards are a good deal only if you don’t carry a balance. Otherwise, you can pay frighteningly high interest rates that offset any benefit you may earn.
