Your Oldest Credit Card Is More Valuable Than You Think

1 month 3 weeks ago

When you’re in your twenties or early thirties, it’s easy to treat your first credit card like an old gym membership—something you signed up for years ago, barely use, and keep meaning to cancel. But that tired plastic sitting in your drawer could actually be doing more for your credit score than your newest rewards card with the flashy sign-up bonus. The age of your credit accounts matters a lot, and the oldest one is often the most important piece of the puzzle.

Your credit score isn’t just about paying bills on time or keeping balances low. It also looks at how long you’ve had credit in the first place. This is called the length of credit history, and it makes up about 15 percent of your FICO score. That might not sound huge, but when you’re trying to buy a car, rent an apartment, or qualify for a good mortgage rate, every point counts. The system wants to see that you can handle credit responsibly over a long period, not just for a few months. So the older your accounts are, the better you look to lenders.

Here’s the catch: when you close an old credit card, you don’t just lose that account. You also lose its age. Credit scoring models look at two things: the age of your oldest account and the average age of all your accounts. If you close the card you got at age 19, your oldest account might suddenly be something you opened at 23. That makes your credit history look shorter and less proven. Even if you have other cards with low balances and perfect payment records, your score can take a hit simply because your history is now younger.

A lot of people close old cards because they think it will help their credit in other ways. Maybe they don’t like the annual fee, or they’re worried that having too much available credit looks risky. But for most people under 35, the opposite is true. Closing an old card with no annual fee is almost always a mistake. That card is your proof to the credit bureaus that you’ve been in the game for a long time. Even if you only use it once every few months to buy a coffee, keeping it open tells the scoring system, “This person has been trusted with credit since before student loans were a thing.”

There’s another factor that makes old accounts valuable: credit utilization. That’s the amount you owe compared to your total credit limit. If your oldest card has a $5,000 limit and you close it, you suddenly lose that $5,000 of available credit. Your utilization ratio goes up even if you haven’t spent a dime more. For example, if you have $2,000 in balances across your other cards and a total limit of $10,000, you’re using 20 percent. Close that old $5,000 card, and your total limit drops to $5,000, pushing your utilization to 40 percent. That change alone can lower your score significantly because high utilization suggests you’re leaning too hard on credit.

So what should you do with that old card? Don’t cancel it. Instead, put one small recurring bill on it—like a streaming service or a phone plan—and set up autopay for the full balance every month. That way, the card stays active, the issuer reports recent activity to the credit bureaus, and you never carry a balance or pay interest. If the card has an annual fee, call the issuer and ask if they can switch it to a no-fee version. Many companies will do a product change without closing your account. That keeps the original account open with its full history intact.

If you don’t have any old credit cards yet, the best time to open one was five years ago. The second best time is today. Start with a basic card, use it sparingly, pay it on time, and don’t close it. Your future self will thank you when you’re 35 and have a fifteen-year credit history that makes lenders fight for your business. Length of credit history is a slow-building asset, but it’s one of the few things in life that literally gets better with age. Treat your oldest card like a prized possession, because in the world of credit scores, it practically is one.
