Your credit score does not go down just because you stop using your credit cards. The FICO formula contains no penalty for silence. What it does contain are categories that reward recent activity, and what your card issuer contains is a policy of closing accounts that sit idle. So the honest answer to “does your credit score go down if you don’t use it” is: not from the math, but often from what the math reacts to after your bank closes the dormant account and your available credit shrinks.
The distinction matters because it changes what you actually need to do. You don’t have to spend money to protect your score. You have to keep the accounts alive.
Why Inactivity Alone Doesn’t Move the Number
Payment history is 35% of a FICO score, and that category rewards a pattern of recent on-time payments.1myFICO. What’s in Your FICO Scores When a card sits unused, no new payment entries appear. The score isn’t docked for that silence, but nothing fresh is being added to reward either. Over months of inactivity your profile flatlines while other consumers who are actively paying down debt keep building recent positive history.
Someone with a 740 score who stops using credit isn’t going to watch their number leak down week by week. The problem is what happens when something else on the report eventually shifts — an old account drops off, a hard inquiry ages out, a limit changes. With no recent positive data to absorb the movement, the score has less cushion.
The Real Threat: Your Issuer Closes the Card
Banks watch dormant accounts because an unused credit line carries risk with no revenue attached. Policies vary, but many issuers close a card after roughly 12 to 24 months of zero activity. Some move faster. Card companies aren’t required to warn you first, though a few send a courtesy email.
That silence is a legal quirk, not an oversight. Federal regulations treat closures for inactivity as separate from an “adverse action,” so the advance-notice rules that apply to denied applications or credit-limit cuts don’t apply here.2Consumer Financial Protection Bureau. Regulation B – 1002.2 Definitions You may find out only when you try to use the card, and by then the score effect is already in the report.
What the Closure Does to Utilization
Amounts owed is 30% of a FICO score, and credit utilization — the share of your available revolving credit you’re actually using — is the main driver.1myFICO. What’s in Your FICO Scores When the issuer closes your unused card, that card’s entire limit disappears from your available credit. If you carry balances elsewhere, your utilization jumps instantly.
Say you have two cards with $10,000 limits each and a $2,000 balance on one. Utilization is 10%. Close the unused card and available credit drops to $10,000, doubling utilization to 20%. Still manageable. But at a $5,000 balance, the same closure pushes you from 25% to 50%, well past the 30% threshold where scoring models start penalizing more aggressively.3Experian. What Is a Credit Utilization Rate People with the highest FICO scores tend to keep utilization in the single digits.
Credit Mix and Account Age
A closure can also thin your credit mix. If the closed card was your only revolving account, the model sees a less diverse profile and that costs a small number of points. Age of history takes a hit too, though on a delay. FICO keeps counting closed accounts in the age calculation while they remain on the report, which is typically about 10 years for accounts in good standing. Once the account falls off entirely, any age benefit goes with it.
If You Can, Shift the Limit Before It’s Gone
If you plan to close a card yourself, or you suspect the issuer might, you can sometimes move the credit limit to another card at the same bank. This preserves your total available credit even though one account is going away.4Experian. Can You Transfer Credit Limits Between Credit Cards Not every issuer allows it, and the reallocation only works between accounts at the same institution. A quick call to customer service settles the question. If reallocation isn’t available, paying down balances on your remaining cards before the closure lands is the next best move.
The Bigger Risk: Losing Your Score Entirely
Even if no accounts get closed, prolonged silence can make you unscorable. FICO requires at least one account reported to a credit bureau within the past six months, plus at least one account that has been open for six months or more.5myFICO. What Are the Minimum Requirements for a FICO Score If every account on your report goes stale for longer than six months, the model can’t produce a number. FICO’s own research supports the floor, finding that scores built on sparse or outdated data don’t reliably predict future behavior.6FICO. FICO Fact: Does FICOs Minimum Scoring Criteria Limit Consumers Access to Credit
Being unscorable is worse than a low score in some ways. Mortgage lenders, auto lenders, and many landlords require a valid FICO score to run an application. Without one, you may not even get a denial. The file just can’t move through automated underwriting.
VantageScore is more forgiving. It can generate a score for anyone with at least one credit account on file, with no requirement for recent activity and no minimum age.7Experian. What Is a VantageScore Credit Score Most large mortgage and auto lenders still pull FICO, so a VantageScore alone won’t get you through the door for a major loan, but it’s useful for monitoring and for lenders who accept it.
If your file has thinned out, UltraFICO lets you bring bank account data into the score. Giving the model permission to look at your checking and savings — transaction frequency, balances, how long the accounts have been open — supplements a sparse credit report.8Experian. What Is UltraFICO and How Do I Use It Rent-reporting services and tools that add utility and phone payments to your credit file work along similar lines.
Inactivity Fees Are Not the Worry
One thing the bank cannot do is charge you for not using the card. Federal rules explicitly prohibit fees based on account inactivity, including fees triggered by failing to meet a transaction count or spending threshold.9Consumer Financial Protection Bureau. Regulation Z – 1026.52 Limitations on Fees A bank can’t hit you with a $50 charge because you didn’t spend $2,000 that year. They can close the account instead, and that’s exactly what most do. The law blocks them from profiting off inactivity; it doesn’t require them to keep the relationship.
One nuance: an issuer can weigh your account activity when deciding whether to waive an annual fee on request. A bank that normally waives the fee for active customers can decline to waive it for an inactive one. That isn’t an inactivity fee. It’s the issuer declining to give you a discount.
Keeping Cards Active Without Really Trying
Preventing an inactivity closure takes almost no effort. Put a small recurring charge on each card you want to keep — a streaming subscription, a cloud storage plan, anything that bills automatically — and set autopay for the full balance. The amount doesn’t matter. The activity does.
How often depends on the issuer. Some banks have closed accounts after as few as six months of no activity; others wait two to three years. Using each card at least once per quarter gives you a comfortable margin with almost every issuer. If you have a card you rarely touch, twice a year is generally enough to keep it alive, though quarterly is safer.
For anyone juggling several cards, a calendar reminder every three months to run one small purchase on each dormant card takes about five minutes and prevents problems that take months to reverse.
If the Damage Is Already Done
If you’ve already gone silent long enough to lose your FICO score or watch accounts get closed, the way back is straightforward but slow. Two tools do most of the work.
- Secured credit cards. You put down a cash deposit, typically equal to your credit limit, use the card for small purchases, and pay in full each month. Confirm the issuer reports to all three bureaus. Keep utilization low — under 30%, ideally in the single digits. Some cardholders graduate to unsecured cards after six months of on-time payments.
- Credit-builder loans. These installment loans hold the borrowed amount in a savings account while you make monthly payments, usually for six to 24 months. A CFPB study found that people without existing debt who took out one of these loans saw scores rise roughly 60 points more than borrowers who already carried debt.10Experian. Credit-Builder Loans vs. Secured Credit Cards: Which Is Better
If you already carry other debt, the secured card tends to work better. Credit-builder loans do their best work when you’re starting from a clean slate. Being added as an authorized user on a family member’s well-managed card can help too, since that account’s history may appear on your report.11myFICO. How Authorized Users Affect FICO Scores
Most people who stick with the process see a usable FICO score within six months and meaningful improvement within a year. The strategy isn’t the hard part. Remembering that credit scores reward boring consistency is.
