Closing Credit Cards can Hurt Your Credit Score
This has become less “strange” in recent years, but closing your credit cards can hurt your score.
What seems like simple financial housecleaning actually affects a variety of factors that go into your credit score. When you close a credit card, your credit limit drops, which increases your credit utilization (bad).
If that card is older than most of the other cards you have, the average age of existing accounts will also fall (bad). These are not as bad as an account in collections, but they could mean the difference between a good credit score and a bad one.
