A strong credit score is essential for financial success, but many people unknowingly sabotage their own scores. While most know that late payments and high credit card balances can hurt their credit, there are other, less obvious factors at play. In this article, we’ll uncover 10 surprising mistakes that might be damaging your credit—and how to fix them.
1. Ignoring Small Unpaid Bills
Even small unpaid bills—like medical copays, utility balances, or forgotten subscription fees—can be sent to collections. Once reported, they can drop your score significantly.
Fix: Regularly check for unpaid balances and set up autopay where possible.
2. Closing Old Credit Accounts
Closing an old credit card reduces your available credit and shortens your credit history—both of which can negatively affect your score.
Fix: Keep old accounts open, especially if they have no annual fee, to maintain a long credit history.
3. Applying for Too Many Loans or Credit Cards at Once
Each hard inquiry from a loan or credit card application can reduce your credit score by a few points. Multiple applications in a short period signal financial distress to lenders.
Fix: Space out credit applications and only apply when necessary.
4. Not Having a Mix of Credit Types
Credit bureaus reward consumers who responsibly manage different types of credit, like credit cards, installment loans, and mortgages. A limited credit mix can lower your score.
Fix: If you only have credit cards, consider adding an installment loan (like a small personal loan) to diversify your credit profile.
5. Paying Rent and Utilities Without Reporting Them
Rent and utility payments don’t automatically get reported to credit bureaus, meaning you’re missing an opportunity to boost your score.
Fix: Use services like Experian Boost or RentTrack to report your on-time payments.
6. Co-Signing Loans Without Monitoring Them
If you co-sign a loan for a friend or family member and they miss payments, it can hurt your credit score—even if you’re not the one using the loan.
Fix: Only co-sign if you trust the borrower, and monitor the account regularly.
7. Not Using Credit at All
Having no credit activity can be just as damaging as having bad credit. Lenders want to see a history of responsible borrowing and repayment.
Fix: Use your credit card for small purchases and pay it off in full each month to keep your account active.
8. Ignoring Credit Card Fees That Lead to Default
Annual fees, late fees, and balance transfer fees can quickly accumulate if ignored, leading to unexpected missed payments and hurting your credit.
Fix: Regularly review your statements and set reminders for due dates.
9. Carrying High Balances on Individual Cards
Even if your overall credit utilization is low, having one maxed-out card can signal risk to lenders.
Fix: Spread balances across multiple cards or request a credit limit increase to improve your utilization ratio.
10. Ignoring Your Credit Report
Mistakes on your credit report, such as incorrect late payments or fraudulent accounts, can significantly impact your score.
Fix: Check your free credit report regularly at AnnualCreditReport.com and dispute any errors.
