Credit Score

Dear Liz: You recently said you don’t need debt to have good credit, but I was told that “credit utilization” — the amount of credit you use compared with your credit limits — is important. Paying off the cards each month means zero balances are reported to the credit bureaus and result in no utilization. Also, older credit accounts help scores, and my older accounts dropped off after a period of time, lowering my average age of credit accounts to four years. How can I fix this? Good credit doesn’t stay on forever.

Answer: It’s not true that paying off your cards results in zero credit utilization. The balance that the card issuers report to the credit bureaus is typically the balance on your statement date. You could pay it off in full the very next day, and the statement date balance would still show up on your credit reports and get calculated into your credit scores.

That’s why it’s important to keep your credit utilization down, even if you pay in full (as you should). It’s good to keep charges below about 30% of your credit limit. Below 20% is even better, and below 10% is best.

Accounts typically won’t drop off your credit reports unless they’re closed. Even then, the closed accounts can remain on your credit reports for many years, contributing to the average age of your accounts. The key to having good scores is to keep a few accounts open and in use, not to carry debt.
