With all of the information out there about credit scoring, it's hard to know if cancelling credit cards will be good or bad for your credit health. It might seem like a no-brainer to close out credit cards that you haven't used in years, but the truth is, it's usually better to keep them open.
First of all, you should know that just because you cancel a credit card does not mean it drops from your credit report. A closed account will stay on your report for years to come. So cancelling a credit card with a negative history is hardly like waving a magic wand to make it disappear. Only time can do that.
So if credit card accounts remain on your report whether you cancel them or not, what’s the harm in cancelling them? Two answers: Length of credit history and a little term called utilization.
The key to a strong credit score is to build up a nice, long history of good credit. Lenders love a consumer with a lengthy proven track record of paying down debt in a timely manner. So it makes sense to keep that first credit card you got as a college freshman back in 1982, especially if the account is in good standing. By keeping the card, even if you never use it, your credit history spans almost three decades. And since length of credit history accounts for 15% of your credit score, that Banana Republic card you opened in 2006 just can’t compare.
The other reason to keep credit cards open is to maintain a healthy credit utilization rate (otherwise known as your debt-to-credit ratio). Basically, the idea here is that it's better to have more credit available to you than less. Credit bureaus tend to drop your credit score if you're using too much of your available credit.
Example: Say I have three credit cards with different credit limits of $8,000, $10,000, and $15,000. I never use the first two, but I routinely have a balance of around $7,000 on the third. This means I'm utilizing 21% of my total credit ($7,000 divided by my total credit limit of $33,000). If I were to cancel the two cards I don't use, then my utilization rate jumps to 47%, which in turn would lower my credit score. (Note that credit bureaus look at both the total utilization rate as well as the utilization rate of each card, so I'd be better served to keep my balance lower on the card with the $15,000 limit, and let one of my other cards pick up the slack.)
While the credit bureaus aren't forthcoming with their precise scoring formulas, we do know that lower utilization rates will significantly boost your score.
If you've already got a low utilization rate (say, under 30%) and are still itching to cancel some of your cards, here are the guidelines you should follow:
Once you've made the decision to cancel a credit card, make sure you do it the right way. Call the credit card company; don't just cut up the card. And make sure they give you a written confirmation for your records.
