The short answer is: it depends on your circumstances and credit history. Leaving a credit card unused won't automatically damage your score, but inactivity can have indirect effects that matter more for some people than others.
Your credit score is built from five main factors, and credit card accounts play a role in several of them. The two most relevant to unused cards are:
Credit utilization ratio (about 30% of your score): This measures how much of your available credit you're actually using. If you have a $5,000 limit and carry a $1,000 balance, your utilization is 20%. An unused card with no balance actually helps this ratio by increasing your total available credit without adding debt.
Payment history (about 35% of your score): This tracks whether you pay bills on time. An inactive card doesn't hurt this—it simply stays out of the equation unless the issuer closes it.
The risk isn't inactivity itself; it's what happens because of it.
The issuer closes your account. Credit card companies sometimes close accounts that show no activity for an extended period—often six months to a year, though policies vary. When that happens, two things can occur:
You forget about it. An unused card sitting in a drawer can become a security risk if lost or stolen, and it's harder to notice fraudulent activity.
Whether inactivity affects your score depends on:
| Factor | Impact |
|---|---|
| How many cards you have | One inactive card among five has less effect than one of two. |
| Your current utilization ratio | If you carry high balances elsewhere, an unused card's available credit helps. If you carry no balances, its absence matters less. |
| Issuer's inactivity policy | Some companies are more aggressive about closing dormant accounts; others are lenient. |
| Your overall credit profile | A strong credit history with multiple active accounts is more resilient to a single closed account than a thinner profile. |
| How long it's been unused | A few months of inactivity is different from years. |
If you're concerned about account closure or want to maintain the credit benefits:
None of these require you to carry a balance or pay interest—the score benefit comes from the available credit and payment history, not from debt.
Avoid closing a card solely to "clean up" your credit profile. Closing an account can lower your score temporarily, whereas keeping it open and unused typically doesn't. If an issuer closes the account first, that's beyond your control—but it doesn't permanently damage your score.
Not using a credit card won't hurt your score as long as the account stays open. The real risk is account closure by the issuer, which depends on their policies and your activity level. If you own a card you no longer need, occasional small purchases kept paid in full will keep it active without requiring you to change your spending habits. Your individual score outcome will depend on your full credit profile—how many other accounts you have, what balances you carry, and your payment history across all of them.
