Why closing a paid-off card can lower a credit score
A credit card with a zero balance may look like an account you no longer need. But closing it can change a key part of how credit scores are calculated: credit utilization, the share of your available revolving credit that you’re using.
Suppose you owe $1,000 across your cards and have $10,000 in total credit limits. You’re using 10% of your available credit. If you close a card with a $5,000 limit while keeping the same debt, your total limit falls to $5,000, and utilization rises to 20%. The balance hasn’t grown, but it now takes up a larger portion of the credit available to you. That change can pull a score down, especially if the remaining balances are high relative to their limits.
The effect may not be immediate—or permanent
Closing an account doesn’t always erase its history from a credit report right away. A closed account in good standing can remain on a report for years, and scoring models may continue to count it in measures of credit history while it’s there. So the utilization change is often the more immediate concern; the effect of losing an account’s age can depend on the scoring model and when the account stops being included.
The size of any score change also depends on the rest of a person’s credit profile. Someone with other cards and low balances may see little difference, while someone relying on that card’s limit may see a more noticeable shift. Lenders and scoring models can weigh credit information differently, so a drop is possible, not guaranteed.
That’s why “paid off” and “safe to close” aren’t always the same thing: removing unused credit can make the debt you still carry look heavier, even when you haven’t borrowed another dollar.
