10 Common Credit Mistakes to Avoid

The single most damaging thing you can do to your credit is miss payments. Payment history accounts for 35% of your credit score-the largest factor.

A single payment that's 30 days late can drop your score by 60-110 points, depending on your starting score. The higher your score, the more you have to lose. And this negative mark stays on your credit report for 7 years.

How to avoid it: Set up autopay for at least the minimum payment on every account. Use calendar reminders as a backup. If you're struggling to pay, contact your creditor before the due date-many will work with you.

Using too much of your available credit is the second-biggest score killer. Credit utilization (30% of your score) measures how much credit you're using compared to your limits.

Maxing out a credit card tells lenders you might be financially stressed and could struggle to repay. Even 50% utilization can hurt your score. The sweet spot is under 30%-ideally under 10%.

How to avoid it: Request credit limit increases regularly. Pay down balances throughout the month, not just at statement time. Spread purchases across multiple cards instead of concentrating on one.

It seems logical: you're not using a card, so you close it. But this often backfires. Closing an old card hurts you two ways: it reduces your total available credit (increasing utilization) and eventually removes that card's history from your credit report (reducing average account age).

A 10-year-old card with a $5,000 limit is valuable credit history. Close it, and you lose that history plus $5,000 of available credit.

How to avoid it: Keep old cards open, even if you rarely use them. Put a small recurring charge (like a subscription) on them to keep them active. Some issuers close inactive accounts, so occasional use matters.

Each credit application creates a hard inquiry, which temporarily lowers your score. Multiple applications in a short period is a red flag to lenders-it looks like you're desperate for credit or about to go on a spending spree.

This is especially damaging if you're applying for different types of credit (credit cards, auto loans, personal loans) simultaneously. Lenders see this as risky behavior.

How to avoid it: Apply strategically and only when you have a good chance of approval. Space out credit card applications by at least 3-6 months. When rate shopping for a mortgage or auto loan, do it within a 14-45 day window-these get counted as a single inquiry.

Many people have errors on their credit reports-some studies suggest up to 25% of reports contain mistakes that could affect scores. These errors could be anything from accounts that aren't yours to incorrect payment history or wrong credit limits.

If you don't check your report, you won't know about errors. And you won't know if someone has opened fraudulent accounts in your name.

How to avoid it: Check your credit reports from all three bureaus at least annually (free at AnnualCreditReport.com). Dispute any errors you find. Consider a credit monitoring service for ongoing alerts.

Mistake #6: Only paying the minimum: Minimum payments keep you in debt for years, costing thousands in interest. Always pay more than the minimum when possible.

Mistake #7: Co-signing loans: When you co-sign, you're 100% responsible if the primary borrower doesn't pay. Their missed payments hurt your credit. Only co-sign if you're prepared to pay the entire debt.

Mistake #8: Not having a credit mix: Having only credit cards shows limited experience. A mix of credit types (cards, installment loans, mortgage) can boost your score-but don't take on unnecessary debt just for variety.

Mistake #9: Ignoring authorized user opportunities: Being added as an authorized user on a responsible person's account can boost your score. Not taking advantage of this is leaving easy points on the table.

Mistake #10: Settling debt without understanding the impact: Settling a debt for less than owed can result in a "settled" status that's nearly as damaging as the original delinquency. Negotiate for "paid as agreed" if possible.
