The Surprising Benefit of Keeping a Credit Card You Never Use

2 weeks 6 days ago

You probably have one. That old credit card from college, or the store card you opened for a one-time discount, is sitting in a drawer with a zero balance. It’s easy to think that card is useless. Why keep it? It’s not hurting anything, but maybe you’re tempted to cancel it to simplify your wallet. Before you do, understand what that card is doing for your credit score behind the scenes.

The biggest reason to hold onto an unused card is your credit history length. Your credit score looks at the average age of all your accounts. The older your accounts, the better. That card from ten years ago is pulling your average up. If you close it, it eventually falls off your report after about seven to ten years. When it does, your average account age drops. That can hurt your score, especially if you don’t have many other old accounts. Even if you have to wait a while for the effect, closing that card is like cutting down a tree that’s been providing shade. The shade is gone once the tree falls, but with credit, the shade disappears later. So keeping the card open, even without using it, preserves that long history.

Another factor is your credit utilization ratio. That’s the amount of credit you’re using compared to your total credit limit. Let’s say you have two cards: one with a $5,000 limit and a balance of $1,000, and another with a $10,000 limit and no balance. Your total credit is $15,000, and you’re using $1,000, so your utilization is about 6.7%. That’s excellent. Now imagine you close that $10,000 card because you never use it. Your total credit becomes $5,000, and your utilization jumps to 20%. That’s still okay, but it’s worse. If you have a bigger balance, closing an unused card can push your utilization over 30%, which is a red flag to lenders. The unused card is actually a safety cushion. It gives you a higher total limit, which keeps your utilization low, even if you don’t touch that card.

But keeping a card you never use requires some attention. Many credit card companies will close an account for inactivity after a year or more. So you need to put a small charge on it occasionally. You can set it to auto-pay a streaming service like Netflix or Spotify. Then set up automatic payments from your bank account, and let it sit. That small monthly charge keeps the card active without you having to think about it. Just make sure you pay the full balance each month so you don’t rack up interest. Another option is to use it once every few months for a cheap purchase, like a coffee or a gas refill, and pay it off immediately.

Of course, there are times when closing an unused card makes sense. If it has an annual fee, and you’re not getting benefits that outweigh that fee, it’s usually better to close it or ask the issuer to downgrade it to a no-fee version. Also, if you have a serious spending problem, and having that available credit is tempting, closing it might be the responsible move. But if you can handle the discipline, keeping it is almost always the smarter play for your long-term credit health. A little bit of effort now can save your score a lot of pain later.

Another thing to consider is the credit mix. Your score likes to see different types of credit, like credit cards, auto loans, and a mortgage. But a credit card is still a credit card. Having more cards doesn’t hurt as long as you manage them well. Older cards also help you build a relationship with a lender. That can come in handy if you ever need a loan or a higher limit later.

The moral of the story is simple. Don’t be too quick to cancel an old credit card just because it’s no longer part of your everyday spending. That card is quietly working for you by lengthening your credit history, lowering your utilization, and giving you a stable foundation for your score. Keep it active with a tiny recurring charge, pay it off automatically, and forget about it. Years from now, when you apply for a mortgage or a car loan, you’ll be glad you did. Your future self will thank you for leaving that card in the drawer.

So before you pick up the phone to close that account, stop and think. That card you never use might be one of your best credit tools.
