Your card app shows a credit score lower than last month's. You don't remember missing a payment. The urge is to do something right away: close a card, or apply for a new one to make up for it. Both can push the score lower.
A credit score usually drops because something changed in your credit report, so find that change first: it tells you whether to act, wait for new data or do nothing.
What changed in my report, and do I act or wait?
Make sure you're comparing the same score: you have more than one, from different bureaus and scoring models.
Then find the line that matches what changed. Each starts with what to do:
- Wait: you paid a card down, but your report still shows the old balance.
- Act: a statement closed with a high balance. Pay it down before the next one.
- Nothing to do: a new account or hard inquiry from an application you made.
- Act: a payment reported 30 or more days late. Bring the account current.
- Act: a card closed, so your total limit shrank. Keep balances under 10% of it.
- Nothing to do: you were removed as an authorized user; that card left your report.
- Nothing to do: an account closed in good standing left your report after 10 years.
- Nothing to do: you paid off a loan, and it now shows as closed.
Why the verdicts differ: payment history is the largest factor in FICO Scores (35% in FICO's published weights). Creditors generally report a missed payment once it's at least 30 days late. In general, a hard inquiry has a small impact on FICO Scores, more if you have few accounts or a short history. It counts for one year and stays on your report for up to two. Experian calls the dip after a loan payoff slight and usually temporary if you keep handling other accounts well.
If an item is wrong, dispute it free with the bureau and the company that reported it. If you don't recognize an account or inquiry, act: dispute it, freeze your credit at all three bureaus (it's free), and if someone is using your information, report it at IdentityTheft.gov.
Why hasn't my score moved since I paid the card?
Example: Priya's card has a $5,000 limit, and she pays the statement balance in full every month. Her statement closes on the 15th, usually with about $400 on it: 8% of the limit ($400 ÷ $5,000). One month she books a $1,150 flight just before the 15th. The statement closes at $1,550 ($400 + $1,150), or 31% ($1,550 ÷ $5,000). On the 17th, her app shows a lower score.
She checks her report: no late payment, no new account, no inquiry. Only the card's balance changed (line 2). That day she pays the full $1,550, but her score doesn't move. Her report still shows $1,550: card issuers usually report once a month, around the statement closing date (line 1). Around the next 15th, her statement closes with about $400 again, 8%, and that's usually the balance the issuer reports.
- 15th: the statement closes at $1,550; around then her report shows that balance, 31% of the limit.
- 17th: she pays the full $1,550, and her report still shows $1,550 (31%).
- Around the next 15th: her statement closes with about $400 again, 8%, and that's usually the balance the issuer reports.
Card issuers usually report once a month, around the statement closing date. Whether Priya's score changes, and by how much, depends on her whole file.

FICO Score 8, the version most widely used by lenders, typically uses the most recently reported balance, so the 31% usually stops counting then. FICO Score 10T also looks at 24 months or more of balances. Whether Priya's score changes, and by how much, depends on her whole file.
Should I close a card or apply for a new one after a drop?
Usually not. Closing a card takes its limit out of your total, so the same balances use more of your available credit. A new application can add a hard inquiry. FICO also says opening several accounts in a short time represents greater risk, especially with a short credit history. Neither move changes what's already reported.

Can you tell which change needs action?
Your score dropped this month. Which change in your report needs action from you, not just time?
- A. A hard inquiry from a card you applied for
- B. A payment marked 30 days late that you know you made on time ✅
- C. A car loan you paid off, now shown as closed
Why: the inquiry and the closed loan follow from your own choices and need nothing more; a late mark on a payment made on time is an error you can dispute free with the bureau and the lender.
