Account Age: Why Older Tradelines Are Worth More
Account age is the length of time a credit card has been open and active. It is one of the most significant factors in determining both the value of a tradeline and the size of the credit score boost it can provide. A card that has been open for 20 years carries far more weight than one that is two years old, both for the primary cardholder and for any authorized users added to the account.
How account age affects your credit score
Length of credit history makes up about 15 percent of your FICO score. This includes the age of your oldest account, your newest account, and the average age of all your accounts. When you are added as an authorized user to an older account, that account’s age gets factored into your credit profile, which can raise your average account age and improve your score.
Why account age matters when buying tradelines
Not all tradelines are priced the same, and account age is one of the main reasons why. A card that is 15 years old with consistent on-time payments represents a long track record of responsible credit use. That history gets passed along to the authorized user, which is why older cards cost more and deliver a stronger impact on your score.
What account age to look for
Here is a general breakdown of how account age typically corresponds to tradeline value:
- 2 to 5 years: Entry-level impact, good for thin credit files
- 5 to 10 years: Moderate impact, solid choice for most buyers
- 10 to 15 years: Strong impact, noticeable score improvements
- 15 years and older: Premium tier, highest score potential
The right choice depends on your current credit profile and what you are trying to accomplish.
Account age vs. credit limit: which matters more
Both matter, but account age tends to have a deeper impact on your score because it affects the length of credit history category directly. A high credit limit helps with utilization, while a long account age improves your score’s foundation. The best tradelines combine both: a long history and a high limit with low utilization.
