Should You Close an Old Credit Card?

A card you no longer use, with a $9,000 limit, sitting at zero. Closing it feels like housekeeping. It takes your reported utilisation from 12.9% to 20.7% the same day, on exactly the same spending, because the limit vanishes and the balance does not.

That is the first of two effects, and they arrive years apart, which is why the advice on this is so confused. Here they are separately.

The two effects, on two timescales

Immediate: your utilisation rises. Utilisation is what you owe divided by your total limits. Closing a card removes its limit from the denominator, so the ratio goes up even though you owe exactly the same. This lands on your next report, within about a month. The CFPB states it directly: closing an account lowers your available credit and increases the percentage you are using.

Much later: your average account age falls. A closed account in good standing generally stays on your report for around ten years and keeps counting towards length of credit history while it is there. So this effect does not arrive when you close the card. It arrives when the account finally drops off, potentially a decade later.

That second point is the one that gets overstated. People close a card and expect their account age to collapse immediately. It does not. And ten years from now, when it does fall off, your other accounts are ten years older, which absorbs much of it.

So the honest ranking: the utilisation effect is the one to worry about, and it is entirely predictable arithmetic.

The utilisation maths, immediately

Four cards, $24,000 of limits between them, $3,100 reported across them.

7.8 percentage points, for an account that was doing nothing. Nothing about the spending changed and nothing was paid off or borrowed.

Two things follow. If you carry no balance at all, the effect is close to zero, because a ratio of nothing to anything is still nothing, and closing is much safer. And the larger the limit relative to your total, the more expensive the closure. Closing a $2,000 card out of $24,000 takes utilisation from 12.9% to 14.1%, which is a difference you can ignore.

Work out your own version before deciding. It is one division and it is the whole case.

The average-age effect, and when it lands

Length of credit history is 15% of a FICO score, and the oldest account matters more than the average.

The sequence people expect is: close the card, lose the history. The actual sequence is: close the card, keep the history on the report for about a decade, then lose it.

That makes it a small consideration in most cases and a large one in exactly one: if the card you are closing is your oldest account. In ten years' time the age of your oldest account resets to whatever your second-oldest is today, and that can be a real step down. If the card in question is the one you opened at twenty-two, keep it, and pay the annual fee if there is one, or downgrade it.

Three reasons to close anyway

The default is keep. These three override it.

1. An annual fee you are not getting value from. A $95 fee on a card you never use is a guaranteed $95 loss against an uncertain and small score benefit. Try two things first. Ask for the fee to be waived, which issuers sometimes do for long-standing customers. Then ask to downgrade to a no-fee card from the same issuer, which usually keeps the same account and its opening date. A downgrade is not a closure, and it is the answer people most often miss.

2. The account is compromised, or you do not trust it. Repeated fraud on the number, a breach at the issuer, or a card you cannot account for. Security outranks a few points of utilisation, and an unwatched open line is a real risk.

3. You cannot stop spending on it. This is the one that matters most and gets mentioned least. If an open card is the reason you are carrying a balance at an average of 22.15%, the interest dwarfs anything the score is worth, and the minimum payment trap shows what that balance does when left alone. Before closing, try removing it from your wallet and your saved payment details, which keeps the limit and removes the temptation. If that has failed twice, close it.

Note what is not on this list: tidiness, having too many cards, or "simplifying". None of those are worth the utilisation increase.

Keeping a card alive with no spending

The problem with keeping it is that issuers close unused accounts, often after a year or two and often without warning. You get the closure anyway, at a time you did not choose.

The fix costs a few dollars a month. Put one small recurring charge on it, a streaming subscription or a phone bill, and set up automatic payment in full. That produces activity, keeps the account open and the limit available, and generates a small reported balance, which is slightly better for scoring than reporting zero.

Check it twice a year to confirm the charge is still going through and the autopay is still attached. A card you have stopped looking at is where fraud sits undetected.

Timing, if you are going to close

The utilisation effect is immediate and then it stabilises as you pay balances down. So the timing rule is simple: close either straight after a major application, or at least six months before the next one. Never in the run-up.

If you are closing more than one, space them out rather than doing it in a single afternoon. And pay balances down first, so the ratio you are worsening starts from a lower base.

When this does not apply

If you carry no balance on any card. Your utilisation is near zero and closing one changes almost nothing. The only remaining consideration is the oldest-account question, and if this is not your oldest card you can close it without much thought.

If the card is a store card with a small limit. These usually have tiny limits and punitive rates. Closing one barely moves utilisation and removes a card you were never going to use well. The exception is if it is genuinely your oldest account.

If you are rebuilding credit from a thin file. Every open account is doing more work than it would in a thick file, and closing one costs proportionally more. Keep everything open.

If the account is joint or you are an authorised user. Different rules apply and the account may be affecting two people's reports. Work out whose file it sits on before closing anything.

If the card is charged an annual fee and you use the benefits. Then it is not a cost, it is a purchase, and the question is whether the benefits are worth the fee rather than what closing does to your score.

Next steps

1. List every card with its limit, its balance and its opening date.
2. Work out your utilisation now, and again with the card's limit removed. That difference is the price of closing.
3. Check whether it is your oldest account. If it is, keep it.
4. If there is a fee, phone and ask for a waiver, then ask about a downgrade to a no-fee card, before considering closure.
5. If you keep it, attach one small recurring charge and automatic payment in full.
6. If you close it, do it well away from any application, and after paying balances down: see what actually moves your credit score.
