Why Do Younger People Tend to Have Lower Credit Scores?
Younger borrowers as a group tend to post lower average credit scores than older ones, and it’s tempting to read that as a statement about financial habits. Mostly, it’s a statement about arithmetic — there simply hasn’t been as much time for a file to build.
The short answer
Younger people tend to have lower scores mainly because scoring models reward a longer credit history, and a shorter history is a near-universal feature of being newer to credit, not a sign of poor habits. Structural factors like a thin credit file, fewer account types, and less time for any single mark to fade all stack in the same direction early on. These effects tend to ease naturally with time, independent of any change in behavior.
Length of history is baked into the math
Credit history length is one of several factors that make up a score, and it’s one that simply cannot be accelerated — it accumulates only as time passes. Someone who opened their first account recently has, by definition, a shorter average account age than someone who has held accounts for a decade or more, even if both are making every payment on time. This single structural factor pulls younger files toward the lower end of the range almost automatically.
Fewer accounts, less variety
Younger borrowers also tend to have fewer accounts overall, and often fewer types of credit — perhaps a single card and no installment loan, for example — simply because there hasn’t been an occasion yet to take on a mortgage, an auto loan, or a second card. A thinner file gives a scoring model less to work with, which can produce a more conservative score than a thicker file would, even when the underlying behavior is equally sound.
New activity has an outsized effect on a short file
In a file with limited history, a single new account or a single missed payment moves the needle more than it would in a longer, more established file, where one event gets diluted across years of other data. This means that ordinary, expected steps — opening a first card, taking out a first loan — can each cause a temporary dip that would barely register in an older file with more history to average across.
Ways some younger borrowers work around this
A few common approaches address the structural gap directly rather than trying to out-behave it:
- Becoming an authorized user. Being added to an established account can extend a file’s visible history, since that account’s age and payment record may be reflected on the added person’s report as well, a dynamic covered in more depth in how being an authorized user can help build someone’s credit.
- Keeping a first account open. Since account age keeps counting only as long as an account remains open and reported, holding onto that early account lets its age contribute for as long as possible.
- Being patient with new accounts. A new account’s initial dip in average age is temporary and fades as the account matures alongside the rest of the file.
The takeaway
A lower average score among younger borrowers reflects the mechanics of how scoring models treat time and history far more than it reflects anything about financial discipline. The gap tends to close gradually, on its own, simply by staying in the credit system long enough for a file to mature.
