You checked your credit score and your heart sank. It dropped 20, 50, or even 100 points seemingly overnight.
I've been a credit expert for 15 years, and this is the #1 question I get asked.
The good news? Credit score drops usually have clear explanations. The better news? Most are fixable.
Let me walk you through the most common reasons your credit score dropped and exactly what to do about each one.
The Most Common Reasons Your Credit Score Dropped
1. You Made a Late Payment (Even by One Day)
Impact: 60-110 point drop Timeline: Shows up within 30 days
This is the big one. Even a single late payment can tank your score, especially if you normally pay on time. Credit scoring models see this as a major red flag.
What to do:
- Call your lender immediately and ask for a goodwill deletion
- Set up autopay to prevent future late payments
- If it's your first offense, many creditors will remove it as a courtesy
2. Your Credit Utilization Spiked
Impact: 10-45 point drop Timeline: Shows up within 30 days
Your credit utilization is how much of your available credit you're using. If you normally keep balances low but suddenly max out a card, your score will plummet.
What to do:
- Pay down balances immediately
- Consider making multiple payments per month
- Ask for credit limit increases to lower your utilization ratio
3. You Applied for New Credit
Impact: 5-10 point drop per inquiry Timeline: Shows up within days
Each hard inquiry (when you apply for credit) dings your score slightly. Multiple inquiries in a short period can add up.
What to do:
- Limit new credit applications
- Shop for loans within a 14-45 day window (multiple auto/mortgage inquiries count as one)
- Wait 6 months between credit card applications
4. An Account Went to Collections
Impact: 50-100+ point drop Timeline: Shows up within 30-60 days
Collections accounts are credit score killers. Even a small medical bill or utility payment can cause massive damage.
What to do:
- Pay the collection if it's recent and accurate
- Negotiate a "pay for delete" agreement
- Dispute the collection if it's inaccurate or not yours
5. You Closed an Old Credit Card
Impact: 10-30 point drop Timeline: May not show up for months
Closing cards reduces your available credit and can increase your utilization ratio. It also shortens your credit history length eventually.
What to do:
- Keep old cards open, even if you don't use them
- Use the card occasionally to keep it active
- If you must close it, pay down other balances first
6. Your Credit Limit Was Reduced
Impact: 10-40 point drop Timeline: Shows up within 30 days
Credit card companies sometimes reduce limits, especially during economic uncertainty. This automatically increases your utilization ratio.
What to do:
- Call and ask for your limit to be restored
- Pay down the balance to compensate
- Apply for a new card to increase total available credit
7. You Co-Signed for Someone Who Didn't Pay
Impact: 30-100+ point drop Timeline: Shows up within 30 days
When you co-sign, you're 100% responsible for the debt. If the primary borrower misses payments, it hits your credit too.
What to do:
- Make the payments yourself to stop further damage
- Contact the primary borrower immediately
- Consider asking the lender to remove you as co-signer (rare but possible)
8. Identity Theft or Fraud
Impact: Varies widely Timeline: Can happen anytime
Someone opened accounts in your name or used your existing accounts fraudulently. This can cause sudden, dramatic score drops.
What to do:
- File a fraud alert with all three credit bureaus
- Dispute fraudulent accounts immediately
- File a police report and FTC identity theft report
- Monitor your credit closely going forward
9. A Promotional Rate Expired
Impact: 5-20 point drop Timeline: Shows up within 30 days
If you had a 0% APR promotion and carried a balance, your utilization ratio might have effectively increased when calculated at the new rate.
What to do:
- Pay down the balance aggressively
- Transfer to another 0% card if you qualify
- Create a payment plan to eliminate the debt
10. You Paid Off a Loan
Impact: 5-15 point drop Timeline: Shows up within 30 days
This seems backwards, but paying off an installment loan (car, mortgage, personal loan) can temporarily lower your score by reducing your "credit mix."
What to do:
- Don't worry—this is temporary and recovers quickly
- Keep making all other payments on time
- Consider this a good trade-off for being debt-free
Less Common But Possible Reasons
11. Reporting Errors
Credit bureaus make mistakes. A payment might be reported as late when it wasn't, or an account might show the wrong balance.
12. Student Loan Status Changes
Going from in-school deferment to repayment, or from forbearance to active repayment, can affect your score.
13. Bankruptcy or Foreclosure
These major negative events can drop scores by 100-200 points and stay on your report for years.
14. Charge-offs or Repossessions
When creditors give up on collecting a debt, they "charge it off." This devastates your credit score.
15. Credit Report Updates
Sometimes old positive accounts fall off your report, or negative accounts are updated with new information.
How to Investigate Your Credit Score Drop
Step 1: Get Your Credit Reports
Visit AnnualCreditReport.com and pull all three reports (Experian, Equifax, TransUnion). Look for:
- New accounts you didn't open
- Incorrect payment histories
- Wrong balances or credit limits
- Accounts that aren't yours
Step 2: Check Your Credit Score History
Use Credit Karma, Chase Credit Journey, or your bank's free credit monitoring to see when the drop occurred.
Step 3: Compare Reports
Look for differences between what you expected and what's actually reporting. Even small errors can impact your score.
Step 4: Document Everything
Take screenshots, print reports, and keep records of all communications with creditors and credit bureaus.

- Charge-offs: 12-24 months of positive payment history
Prevention Tips

The Bottom Line
Credit score drops are scary, but they're usually fixable. The key is acting quickly once you notice the drop. Don't panic—focus on identifying the cause and taking immediate action.
Remember: Your credit score is a snapshot of your financial behavior. One mistake doesn't define your financial future. With the right approach, you can recover from almost any credit score drop.
Quick Action Checklist
When your credit score drops:
- Pull all three credit reports immediately
- Identify what changed from your last report
- Contact creditors if there are errors
- Pay down high balances
- Set up autopay for all bills
- Monitor your credit monthly going forward
Your credit score will recover. Focus on the actions you can control, and be patient with the process. I've seen people bounce back from 500 to 750+ in less than two years with the right strategy.
FAQ
Q: Can checking my credit score make it drop? A: No, checking your own credit score is a "soft inquiry" and doesn't affect your score.
Q: How much can my score drop from one late payment? A: It depends on your current score, but I've seen drops of 60-110 points from a single late payment.
Q: Will paying off collections immediately improve my score? A: Not necessarily. Paid collections still hurt your score, but they're better than unpaid ones.
Q: Should I close credit cards I don't use? A: Generally no, unless there's an annual fee. Keep them open to maintain your credit history and available credit.
