Dear Liz: I paid off my high-interest credit cards. Should I close the accounts or leave them open? I heard a long time ago that closing the accounts will affect my credit score because less credit is available to me. But I don’t want to use these credit cards anymore because they have a high interest rate.
Answer: A card’s interest rate is irrelevant if you pay off your balances in full each month, which is the best way to use credit cards.
Closing a bunch of your credit cards at once can have a negative impact on your credit scores. That’s why the general advice is to leave cards open if possible, making a small charge once in a while so the issuer doesn’t close them.
If you can’t trust yourself to use the cards responsibly, though, closing them may be the best option. Or you can ask the issuers for a “product change” to a lower interest card.
