常见问题

How is average age of credit calculated?

Average age of credit is calculated by adding up the age of every open account on your credit report and dividing by the total number of accounts. For example, if you have three accounts aged 10 years, 5 years, and 1 year, your average age is 5.3 years.

Does closing an old credit card hurt your score?

Yes. Closing an old card removes it from your average age calculation, lowers your total available credit (increasing utilization), and eventually removes positive payment history. Keep old cards open even if you rarely use them.

What is a good average age of credit?

Seven years or more is considered excellent for FICO scoring. Four to six years is good. Two to three years is fair. Under two years is thin and will limit your score. The longer your accounts have been open, the better.
