You logged into your bank app, took a look at your credit score, and felt sick to your stomach.
Everything was fine last month. This month, it has gone down – 40 points, maybe 60, maybe more. And you swear you wouldn’t have done anything different.
Here’s the brutal truth: You don’t have to do anything dramatic to lower your score. A single late bill, a maxed-out card, even a misplaced loan payment can make it worse.
You too are not alone. The national average FICO score has now fallen for two consecutive years, hitting 715 in 2025 — down from 717 a year ago and 718 the year before that. Rising credit card usage and a spike in missed payments – partly linked to the resumption of student loan default reporting – led to the decline.
So if your score has just dropped, you have plenty of company. The question is, who among these seven things did this?
1. You missed a payment
This is the big one. Payment history makes up 35% of your FICO score – the biggest factor in the formula.
A bill is missed by 30 days or more, and your lender will report it to the bureau. That one slip could cost you 60 to 110 points, depending on where your score started from.
The higher your score, the faster you will fall. Someone with a score of 800 loses more points if a payment is 30 days late than someone with a 680. The math seems unfair, but that’s how the model works.
Pay by the 29th day and you may have to pay a late fee, but the bureau won’t know about it. Get past 30 days, and the damage has been done.
2. Your credit card balance has increased
Balance – mostly your credit utilization – makes up 30% of your FICO score. This is the second biggest factor.
Here’s how usage works. If you have a credit limit of $10,000 and you have $3,500 left, you are using 35% of your available credit. Most experts recommend keeping that ratio below 30%, and the highest-scoring consumers keep it below 10%.
Hunt? Your card issuer reports your balance once a month, usually on the statement close date – not the due date. So even if you pay in full every month, a big purchase before the statement goes out could increase your usage and lower your score.
Solution: Pay the balance before the due date and not just before the due date. If your total balance is huge, check out these ways to pay off credit card debt.
3. You have applied for new credit
Every time you apply for a card, car loan or mortgage, the lender pulls your report. This is a difficult inquiry, and it highlights some points.
A tough inquiry is no big deal. There are three or four in a small window. Lenders feel like you are struggling for money.
There is one exception. If you’re rate-shopping for a mortgage or auto loan, the bureaus typically group inquiries into a single program within a 30-day period. So shopping around won’t penalize you – as long as you do it fast.
4. You’ve closed an old credit card
This bothers a lot of people. You decide to “clean up” your finances by closing an old card you no longer use. Feels responsible. Hurts your score.
Two things happen. First, you lose that card’s available credit, causing your utilization ratio to increase overnight. Second, if it was one of your older accounts, you’ve lowered the average age of your credit history – and length of history accounts for 15% of your score.
Rule: Don’t close old cards just to feel neat. Stick them in a drawer, charge each one a small recurring fee and pay it off every month.
Exception: If you’re paying a hefty annual fee, either close the card, or even better, call the company and tell them if they don’t drop the annual fee, you’ll drop the card.

5. You paid off the loan
Wait – did I lose money paying off the loan?
Sometimes, yes. Your credit mix – the different types of accounts you have – is 10% of your score. The scoring model likes to look at both revolving accounts (credit cards) and installment accounts (car loans, mortgages, student loans).
If you just paid off your only car loan and now your report shows nothing but credit cards, your mix gets diluted. Your score may drop 10 or 20 points.
Never avoid repaying your loan to protect your score. That would be madness. Just know that the decline is temporary and meaningless. You are better off without debt.
6. Your student loans come due
This is the biggest news of this year. Pandemic-era protections that paused student loan payments officially ended, and the 12-month “on-ramp” that kept missed payments off credit reports expires in October 2024.
The result has been genocide. According to the Federal Reserve Bank of New York, 2.2 million delinquent student loan borrowers saw their credit scores drop by more than 100 points between January and March 2025. Another 1 million experienced declines of 150 points or more.
FICO’s spring 2026 data shows that the average new student loan delinquency now causes borrowers to lose 62 points from their FICO score — enough to bring you from “good” credit to “fair” in the same reporting cycle.
If your federal loan is 90 days past due, your servicer will notify you. The solution is not great: Contact the service provider immediately about an income-driven repayment plan or rehabilitation. Every additional month it goes into default makes recovery harder.
7. There is an error on your credit report
Sometimes a loss is not your fault. The Federal Trade Commission previously estimated that approximately one in five Americans have errors on at least one of their three credit reports.
A payment may have been reported late when it was not. An account you closed years ago may be showing as open with the same balance. It is possible that someone has stolen your identity and opened a card in your name.

bottom line
Your credit score is not a secret, and it’s not fragile. It’s just a snapshot of your borrowing habits at one point in time.
If your score has just taken a dip, find out which of these seven culprits caused the damage and deal with it. Most dropsy resolve within a few months once you fix the underlying problem. Some – like missed payments – take longer to fade away, but they do fade away.
The most important thing to remember: a single bad month is not permanent. Make payments on time, keep your balances low and keep your oldest accounts open. For more information, see “7 Ways to Raise Your Credit Score Fast.” The score will be returned.
