How Not Using Your Credit Card Affects Your Credit Score

Not using a credit card does hurt your score, but the damage is usually small and slow

A credit card you never use will not destroy your score overnight. But it will drag your score down over time, because credit scoring models reward active card use. The longer a card sits unused, the more it can hurt — especially if it is one of your older accounts or if you have few other cards open.

The damage happens through two mechanisms. First, your credit utilization ratio — the percentage of your available credit you are actually using — stays artificially high when you have unused cards. If you have $5,000 in available credit across all your cards but only use one card with a $2,000 limit, your utilization looks like 100 percent instead of 20 percent. Second, credit bureaus see inactivity as a sign of risk. A card with no recent transactions looks abandoned, and scoring models treat abandoned accounts as less reliable than active ones.

Key Takeaways

• An unused credit card will lower your score gradually because it does not contribute to your credit utilization ratio, making your overall utilization appear higher than it actually is.
• Credit scoring models reward recent activity, so a card with no transactions in six months or longer signals risk to lenders, even if you have never missed a payment.
• Closing an unused card can hurt your score more than leaving it open, because closing it removes available credit and can raise your utilization ratio immediately.
• A small purchase every few months — even a dollar or two — keeps a card active in the eyes of credit bureaus and prevents the score damage that comes with dormancy.
• The damage from one unused card is usually modest if you have other active accounts, but it compounds if most of your cards are sitting idle.

Why credit bureaus penalize cards you do not use

Credit scoring models, including the widely used FICO and VantageScore models, treat inactivity as a warning sign. When a card has no transactions for several months, the bureau's system logs it as dormant. Dormant accounts suggest you may have abandoned the card or that you are no longer creditworthy enough to use it — even though neither may be true.

The scoring penalty is not immediate. Most credit bureaus do not flag a card as inactive until six months or more have passed without a transaction. But once that threshold is crossed, the account begins to weigh against you. Some card issuers will even close inactive accounts on their own, which creates a separate problem: a closed account removes available credit from your total, raising your utilization ratio and lowering your score further.

How unused cards affect your credit utilization ratio

Your credit utilization ratio is the total amount of credit you are using divided by the total amount available to you. If you have three cards with $5,000 limits each — $15,000 total available — and you carry a $3,000 balance on one card, your utilization is 20 percent. That is healthy.

But if one of those cards sits unused, it still counts toward your available credit. If the card issuer closes that unused card because of inactivity, you lose that $5,000 in available credit. Now your total available credit drops to $10,000, and your $3,000 balance becomes 30 percent utilization. Your score drops, not because you spent more, but because you have less available credit. This is why closing an unused card often hurts your score more than leaving it open.

The difference between leaving a card open and closing it

Leaving an unused card open is almost always better for your score than closing it. An open card with no recent activity will lower your score slowly. A closed card lowers it faster and more severely, because closing removes available credit immediately.

There is one exception: if the card charges an annual fee and you are not using it, the fee costs you money for no benefit. In that case, the financial harm of the fee may outweigh the credit score benefit of keeping the card open. But if the card has no annual fee, there is no reason to close it. The card issuer does not care if you use it or not — they make money from interchange fees when other people use their cards — and you benefit from the available credit sitting there, even if you never touch it.

How to keep an unused card active without spending money

The simplest way to prevent score damage is to use the card occasionally. You do not need to carry a balance or spend much. A single small purchase every three to six months — a coffee, a gas fill-up, a dollar item online — is enough to keep the account active in the credit bureau's eyes.

After you make the purchase, pay it off in full when the bill arrives. This keeps the account active, prevents interest charges, and maintains a zero balance on the card. The credit bureau sees recent activity, the card issuer sees a transaction, and your score stays stable. If you are worried about forgetting, set a phone reminder for every four months to buy something small on the card, or set up an automatic small recurring charge like a streaming service and pay it off immediately when the bill comes.

When the score damage from one unused card actually matters

If you have five active cards and one sits unused, the damage to your score is usually modest — perhaps five to ten points, depending on how long it has been inactive and how much credit you have in total. That is not nothing, but it is not catastrophic either.

The damage becomes more serious if most of your cards are inactive. If you have ten cards and nine of them have no recent transactions, your score will take a real hit. The same is true if the unused card is one of your oldest accounts. Credit bureaus reward length of credit history, and an old card that goes dormant loses that advantage. An old card that stays active — even with tiny purchases — protects your score in two ways: it keeps your history long, and it keeps your utilization low.

What happens if a card issuer closes your account for inactivity

Some card issuers will close an account if it has been inactive for a year or more. When this happens, you lose the available credit, your utilization ratio rises, and your score drops. You also lose the account history itself if the card issuer reports the closure to the credit bureaus as a closed account rather than an account you closed.

The best defense is to use the card before the issuer closes it. Check your card statements or log into your account every few months to see which cards have had no activity. Make a small purchase on any card that has been dormant for four or five months. This keeps the issuer from ever reaching the point where they consider closing it.

Frequently Asked Questions

How long can a credit card sit unused before it hurts my score?

Most credit bureaus begin to penalize inactivity after six months without a transaction. However, card issuers may close the account themselves after twelve months or more of no activity. To be safe, use the card at least once every four to six months, even if it is just a small purchase.

Will my score recover if I start using an unused card again?

Yes. Once you resume using the card, the credit bureau will see recent activity and the inactivity penalty will fade. Your score will not bounce back instantly, but it will begin to improve within a month or two of regular use. The longer you keep the card active going forward, the faster the recovery.

Is it better to close a credit card or leave it open if I am not using it?

Leave it open if there is no annual fee. An open unused card hurts your score less than a closed one, because the available credit still counts toward your utilization ratio. Closing the card removes that credit and can lower your score more than leaving it alone.

Can I use a credit card just once and then not use it for months?

One transaction will keep the account from being flagged as dormant, but the longer you go between uses, the more the inactivity penalty applies. For the best outcome, use the card at least once every four to six months. This keeps it active in the credit bureau's system and prevents the issuer from closing it.

Does having too many unused credit cards hurt my score?

Yes, but the effect depends on how many you have and how much total available credit they represent. One unused card among several active ones causes minor damage. But if most of your cards are inactive, the combined effect can lower your score noticeably. Keep your oldest and highest-limit cards active, even with small purchases, to protect your score.
