How to avoid the 5 most common credit mistakes.

Last verified May 23, 2026

The direct answer. The five most common credit mistakes are: closing old credit cards, applying for several accounts in a short window, carrying balances close to the credit limit, ignoring the statement closing date, and skipping the annual credit report pull. Avoiding all five protects 30 to 60 points of FICO score that most borrowers give away without knowing it.

Step 1 of 5

Keep your oldest credit cards open.

Length of credit history is 15 percent of your FICO score. Closing an old card removes its credit limit from your total available credit, which raises utilization. After about ten years, the closed account ages off and your average age drops too. Keep no-fee cards open. Use them once a quarter for a small charge.

Step 2 of 5

Space out your credit applications.

New credit is 10 percent of your FICO score. Each hard inquiry trims a few points and the effect lasts about a year. Several applications in a short window signal risk to lenders. Space major applications six to twelve months apart. Use pre-qualification tools with a soft pull first.

Step 3 of 5

Keep balances well below your limit.

Utilization is 30 percent of your FICO score. Balances above 30 percent of your limit on any card lower the score. The lift kicks in hardest below 10 percent. The number that reports is the balance on your statement closing date, so pay it down before that date, not just before the due date.

Step 4 of 5

Pay attention to the statement closing date as much as the due date.

The due date is when the lender wants payment. The statement closing date is what the bureaus see. They are usually 21 to 25 days apart. To lower reported utilization, make a payment one to two days before the statement closes. To avoid interest, pay the full statement balance by the due date. Do both.

Step 5 of 5

Pull your credit report at least once a year.

Roughly one in five credit reports contains an error. An unnoticed mistake can quietly cost score points and may signal identity theft. Pull all three reports free at AnnualCreditReport.com once a year. Stagger them every four months for year-round monitoring. Dispute anything wrong in writing.

Frequently Asked Questions

Questions readers ask most often.

What is the worst thing for my credit score?

A missed payment that reaches 30 days past due. One can drop a FICO score 60 to 110 points. Set autopay on every credit account for at least the minimum to prevent it. The impact fades over 12 to 24 months and the mark stays on the report seven years.

Does closing a credit card hurt my credit score?

Often yes. Closing a card removes its credit limit from your total available credit, which raises utilization. Once the closed account ages off in about ten years, it shortens your average account age too. Keep no-fee cards open and use them for a small charge every 60 to 90 days.

How many credit card applications are too many?

Several applications in a six-month window can drop your score 10 to 20 points and signal risk to lenders. Space major applications six to twelve months apart. Use pre-qualification tools (soft pull only) before you apply.

What credit card balance hurts my score the most?

Any balance above 30 percent of the card's limit pulls the score down. Above 70 percent of the limit, the drop accelerates sharply. Get every card below 30 percent first, then aim for under 10 percent for the biggest lift.

Why is the statement closing date as important as the due date?

The balance on your statement closing date is the one reported to the credit bureaus, not the balance after you pay. To lower reported utilization, make a payment one to two days before the statement closes. To avoid interest, pay the full statement balance by the due date.
