The Formula for Average Credit Age#
When checking your credit score, you might have noticed a metric called Average Age of Accounts (AAoA) or credit age. It is a critical component of your FICO and VantageScore algorithms. But how exactly is it calculated, and why does it matter?
The math behind your average credit age is straightforward. The credit bureaus take the age of every single account on your credit report, add them all up, and divide by the total number of accounts.
Example Calculation:
- Credit Card A: 5 years old (60 months)
- Credit Card B: 3 years old (36 months)
- Auto Loan: 1 year old (12 months)
Total months = 60 + 36 + 12 = 108 months. Average Age = 108 / 3 = 36 months (or 3 years).

Length of credit history accounts for 15% of your FICO Score. Lenders want to see that you have a long, proven track record of managing debt responsibly. A longer credit age indicates stability.
How to Improve Your Credit Age#
- Keep old accounts open: Don't close your oldest credit cards, even if you rarely use them. Keep them active with a small recurring charge.
- Become an authorized user: If a family member has an old, well-managed credit card, being added as an authorized user can instantly inherit that card's age on your report.
- Be cautious with new applications: Every time you open a new account, its age is 0 months, which drags down your overall average.
