Not using a credit card does not, by itself, hurt your credit. The damage, when it happens, comes from what the issuer does in response to inactivity: reducing your credit limit, closing the account, or eventually stopping the monthly updates that keep the account visible to scoring models. Any of those can move your score, and a closure can keep affecting it years later when the account finally drops off your report.
What Actually Happens When a Card Sits Idle
An open card with a zero balance is usually good for your score. Its credit limit still counts toward your total available credit, which holds down your overall utilization, and the account keeps aging, which helps the length-of-history part of your score.
The problem is that issuers don’t have to leave an inactive card alone. Federal law bars a creditor from closing a card solely because you haven’t paid finance charges, but it explicitly permits closure once an account has been inactive for three or more consecutive months.1Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans In practice most issuers wait longer, but policies vary, and some card agreements allow closure with little or no advance notice.
Before closing an account outright, some issuers take a smaller step: cutting your credit limit on a card you rarely use or barely draw on.2Experian. Can My Credit Limit Decrease If I Don’t Spend Enough Either move — a lower limit or a closure — is where the score damage starts.
How a Limit Cut or Closure Moves Your Utilization
Credit utilization is roughly 30% of a FICO score.3myFICO. How Are FICO Scores Calculated You calculate it by dividing your total balances across all revolving accounts by your total credit limits.4Equifax. What Is a Credit Utilization Ratio When an issuer shrinks the limit on an unused card, or closes it, your total available credit falls. If you carry balances on other cards, your utilization ratio rises even though nothing about your spending has changed.
Scoring models look at both your total utilization and the utilization on each card individually.5Experian. What Is a Credit Utilization Rate Losing the headroom of an unused card can push either or both higher. That’s the mechanism behind most of the score drops people blame on “not using” a card.
What Closure Does to Your Credit History
Length of credit history is about 15% of a FICO score and reflects the age of your oldest account, the age of your newest, and the average age of everything on your report.3myFICO. How Are FICO Scores Calculated A closed account doesn’t disappear right away. If it was in good standing, it typically stays on your report for up to 10 years after closure and continues to count toward your average account age during that time.6TransUnion. How Closing Accounts Can Affect Credit Scores
The bigger hit is delayed. When the closed account finally drops off, your average account age is recalculated without it, which can shorten your visible history — especially if the card was one of your oldest.6TransUnion. How Closing Accounts Can Affect Credit Scores Someone whose oldest tradeline is a card they let go inactive a decade ago can see a real score change the month it comes off.
The Thin-File Risk: Losing Your Score Entirely
If you have several accounts, inactivity on one card is a manageable problem. If your file is thin, it’s a bigger one. FICO requires at least one account that has been reported to a credit bureau within the past six months, plus at least one account that has been open for six months or more.7myFICO. What Are the Minimum Requirements for a FICO Score Stop using all your cards, and eventually issuers stop reporting monthly updates. Miss that six-month window across every account and you can become unscorable under FICO.
VantageScore is more forgiving: it can generate a score from a single account and only requires an update within the past two years.8Experian. What Is a VantageScore Credit Score Lenders use different models, so it’s possible to have one score and not the other, which makes approvals unpredictable.
Rewards You Could Forfeit
The score isn’t the only cost of a closure. Most major issuers — including American Express, Chase, Capital One, Bank of America, Discover, and Wells Fargo — don’t expire rewards while the account is open and in good standing, but closing the account, whether by you or by the issuer, typically wipes out any points, miles, or cash back you haven’t already redeemed. Some Citi programs expire rewards on their own schedule regardless of account status. If you’re sitting on a balance you care about, redeem it before the card goes idle.
How to Keep an Unused Card Active
Using each card at least once every three months keeps you safely above the federal threshold that lets issuers close for inactivity,1Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans and a small purchase is usually enough to have the issuer report the account as active.9Equifax. Inactive Credit Card – Use It or Lose It A few low-effort options:
- Put a small recurring bill, like a streaming subscription, on the card so it charges itself.
- Rotate the card into a routine expense — gas or groceries — once a quarter, then pay it off.
- Turn on autopay so a forgotten $9 charge doesn’t turn into a missed payment. Payment history is 35% of your score, the largest single factor.3myFICO. How Are FICO Scores Calculated
Individual issuers set their own internal timelines, so there’s no universal “safe” frequency. The three-month rhythm is a conservative default.
If the Account Has Already Been Closed
Move quickly. Some issuers will reinstate a recently closed account, sometimes within a window as short as 30 days from the closure date. Call the customer service number on your last statement and ask. Reinstatement is better than reapplying because it keeps the account’s history and usually avoids a hard inquiry.
If the issuer won’t reopen it, a new application is your only path back, and a new card starts its clock at zero — it won’t restore the history you lost. From there, protect what’s left: keep utilization low on your remaining cards, pay on time every month, and consider putting a small recurring charge on another card you tend to ignore so the same thing doesn’t happen twice.
