Account age is a meaningful dimension in many scoring models because long‑standing, well‑managed relationships signal stability. Keeping older accounts active—used lightly and paid on time—can help preserve average age and available credit. Even infrequent, small transactions prevent inactivity closures by some issuers. Before simplifying wallets, weigh the potential scoring impact against annual fees and practicality. Thoughtful portfolio management balances convenience with the subtle credit advantages of seasoned accounts.
