What Hurts Your Credit Score? 10 Things to Avoid in 2026

Payment history is 35% of your FICO score — the single biggest factor. Even one payment made 30 days late can drop a high score by 60–100 points, and the higher your starting score, the bigger the fall. The damage grows the later you pay: 60 days late hurts more than 30, and 90 days more still.

The key detail: a payment must be at least 30 days past due to be reported. If you pay within 29 days of the due date, it typically won't hit your credit report — though you may still owe a late fee. Set up autopay for at least the minimum on every account as a safety net; this single action eliminates the most common cause of credit damage.

Credit utilization — how much of your available credit you're using — is 30% of your score. Using more than 30% of your limit starts to hurt; the highest scores belong to people who stay below 10%. FICO looks at utilization both per-card and across all your cards combined, so one maxed-out card hurts even if your overall usage is low.

The good news: utilization has no memory. Unlike late payments, the moment you pay a balance down and the lender reports the lower number, the damage disappears. This makes it the fastest factor to fix — see how to improve your credit score fast.

When an account goes 90+ days without payment, it may be declared in default and sent to a collections agency. This is a major negative mark that signals serious risk to lenders. A collection account can drop your score significantly and stays on your report for 7 years.

If you have an account heading toward collections, paying it off before it's formally sent to a collection agency has a positive effect compared to letting it go to collections. Medical collections were removed from credit reports under 2025 CFPB rules — if any still appear, dispute them.

Bankruptcy is one of the most severe negative marks. Chapter 7 stays on your credit report for 10 years; Chapter 13 for 7 years. It can drop your score by 100+ points and makes new credit difficult to obtain for years. That said, for people who genuinely can't repay their debt, it can be the right reset — but it should be a last resort. See how to get out of debt without bankruptcy for the alternatives to try first.

Each time you apply for credit, the lender pulls your report — a "hard inquiry" — which usually costs fewer than 5 points and recovers within a few months. The problem is volume: many applications in a short window signal risk and have a compounding effect. Statistically, people actively seeking lots of new credit are more likely to miss future payments, so the scoring model treats it as a warning sign.

Exception: rate shopping for a single installment loan (mortgage, auto, student) within a focused window of 14–45 days counts as one inquiry. This protection does not apply to credit card applications — space those out.

Closing a credit card hurts in two ways: it removes that card's limit from your available credit (raising utilization), and if it's an old account, it can lower your average account age. The impact is largest when you close a high-limit card or your oldest card. Unless a card charges an annual fee you can't justify, keep it open — put a small recurring charge on it to keep it active.

You can do everything right and still have your score damaged by a mistake that isn't yours. The FTC found 1 in 5 Americans has a verified error on at least one credit report — a payment marked late that you made on time, an account that isn't yours, or a balance that's wrong. These errors can cost significant points. Pull your free reports at AnnualCreditReport.com and dispute anything inaccurate; resolved disputes raise scores by an average of 25 points, sometimes 100+.

If someone opens accounts in your name or runs up fraudulent charges, your score can drop from activity you never authorized. A routine score check won't reveal fraud — you have to look at the full report. Review your reports regularly, set up account alerts, and consider a free credit freeze if you're not actively applying for credit. If you find fraud, dispute it immediately and file a report at IdentityTheft.gov.

Having balances on a large number of accounts — even small balances — can weigh on your score. Scoring models look at how many of your accounts carry a balance, not just your total debt. Paying off and keeping a balance on fewer accounts generally looks healthier than spreading small balances across many cards.

Beyond the hard inquiries, opening several new accounts in a short period lowers your average account age and signals risk. New accounts can indicate increased credit risk to the scoring model. If you need more available credit, requesting a limit increase on an existing card is gentler on your score than opening a new account. Space out new accounts and open them only when you have a clear reason.
