You check your credit score and it’s down 20, 40, maybe 60 points. You haven’t missed a payment. You haven’t applied for anything new. Nothing changed. Or so you think.
Credit scores react to things you don’t always notice. Some drops are temporary and fix themselves. Others point to problems on your report that need attention. Here are the most common causes.
Your credit card balance was higher when the statement closed
Utilization is reported based on your statement balance, not your balance on the due date. If you made a large purchase and the statement closed before you paid it off, the bureaus see a high utilization number even if you paid the full balance by the due date.
This is the most common cause of “mysterious” score drops. You spent $3,000 on a card with a $4,000 limit, the statement closed at $3,000 (75% utilization), and your score dropped 30 points. You paid it in full two weeks later, but the damage was already reported.
Fix: pay down the balance before the statement closing date, not just before the due date. Or just wait. The score recovers when the next statement reports a lower balance.
A credit limit was reduced
Some issuers periodically review accounts and reduce credit limits on cards that aren’t being used or on accounts where the cardholder’s financial profile has changed. If your limit goes from $10,000 to $5,000 and you carry a $2,000 balance, your utilization jumps from 20% to 40% overnight.
You might not even get notified. Some issuers send a letter; others don’t. Check your credit card accounts online to see if any limits changed.
Fix: call the issuer and ask for the limit to be restored. If they won’t, pay down the balance on that card to bring utilization back under 30%.
An old account fell off your report
Closed accounts stay on your credit report for up to 10 years after closing. When that 10 years is up, the account disappears. If it was an old account with a long positive history, losing it reduces your average account age, which can lower your score.
This is a normal part of how credit aging works. There’s nothing to fix. Your score adjusts over time as your remaining accounts age.
Someone ran a hard inquiry you forgot about
Applied for a store credit card at checkout? Authorized a landlord to check your credit? Pre-approved for a car loan at the dealership and they pulled your credit? These all generate hard inquiries. If you forgot about them, the score drop seems to come from nowhere.
Check the inquiries section of your credit report. Any hard inquiry you don’t recognize might be unauthorized, which you can dispute.
An account went to collections without your knowledge
Medical bills are the biggest offender here. You might have an unpaid bill from a provider you thought was covered by insurance. The provider sent it to collections after 90 or 180 days. The collections account appears on your credit report and drops your score, and you had no idea the bill existed.
Check the collections section of your report. If something’s there, verify it’s legitimate, then either pay it, negotiate it, or dispute it if it’s wrong.
A creditor reported incorrect information
The creditor accidentally reported a late payment, a higher balance, or some other error. It happens more often than you’d expect. The only way to catch it is to review your credit report details, not just the score.
If you find an error, dispute it with the bureau. Provide documentation showing the correct information.
Normal score fluctuations
Credit scores fluctuate by small amounts regularly. A 5 to 10 point swing from month to month is normal and nothing to worry about. It can happen just from the timing of when different accounts report their balances.
Only investigate drops of 20 points or more, or drops that persist for more than one month.
What to do when your score drops
Pull your credit reports from all three bureaus. Compare the details to your own records. Look for new accounts you didn’t open (possible fraud), incorrect balances or late payments, new collections accounts, and credit limit changes.
If everything is accurate and the drop is from utilization or normal fluctuation, wait a month. It usually corrects itself when updated balances are reported. If there’s an error or fraud, dispute it immediately. The sooner you catch it, the faster it gets resolved.
