Common credit mistakes and how to avoid them

Summary

• Always pay your credit card bill on time—late payments can negatively affect your credit score.

• Aim to keep credit card balances and other revolving credit balances low so your use of credit stays healthy. This is called your credit utilization—the percentage of your available credit you’re using. 

• Apply for new credit only when you need it.

• Always review your credit card statements and credit reports. 

• Keep older accounts open if they fit your financial plan and are worth the cost of any potential fees. 

• Avoid cash advances because interest often starts right away and fees typically apply.

• To help pay off debt faster, pay more than the minimum payment on your credit card balance.

• Be aware of any due dates and fees so costs don’t pile up.

• Build a steady credit history with simple, repeatable habits.

Good credit usually follows steady habits, not one big move. Most mistakes start small and build over time, like a late payment that slips by or a balance that grows without the necessary funds to pay it off. 

Here are a few of the more common credit mistakes people make and how to avoid them. With a little attention and a simple routine, you may be able to lower costs, maintain good credit habits, and keep your budget on track.

Making a late payment

A late payment is any payment you make after the due date. Late payments can negatively affect your score and add fees and extra interest. To help avoid late payments, you can turn on automatic payments for at least the minimum so you don’t miss a deadline. Then, add calendar alerts a few days before each due date. If a payment looks tight, you can call your lender early and ask about options; many lenders offer hardship programs or may consider goodwill adjustments, but these are discretionary.

Using too much of your limit

Credit utilization means the share of your revolving credit limit you’re using. A $300 balance on a $1,000 limit is 30% utilization. High utilization signals risk and can pull your score down. Try to keep balances under 30% on each credit card—the lower the better. Try making an extra payment right before your statement closes. It helps show a smaller balance, which can be good for your score.

Paying only the minimum

The minimum payment is the smallest amount you must pay on a loan to keep your account current. It helps you avoid a late fee, but it can also stretch debt over months and sometimes years. When you can, pay the full statement balance so purchases don’t collect interest. Even small extra payments can make a big difference over time by reducing interest and helping you pay down debt sooner.

Applying for too much credit at once

A hard inquiry happens when a lender checks your credit to decide on an application. While one or two inquiries are usually not impactful to your score, several in a short period can signal higher risk. 

With this in mind, it may make sense to apply for new credit only when you need to. However, if you’re rate shopping for a mortgage, auto loan, or student loan, multiple inquiries within a short window (depending on the scoring model, but typically 15-45 days) are often counted as one for scoring purposes.

Closing old credit card accounts

Length of credit history looks at how long your accounts have been open—and a longer credit history, depending on its strength, can be better than a shorter one. 

Closing an old card can shorten the average age of your credit. It can also raise your credit utilization ratio. If an older card has no annual fee and still fits your plan, you may want to consider keeping it open. Then, you can make a small purchase every few months and pay it in full so the account stays active.

Ignoring your credit reports

A credit report is the file that lists your accounts, balances, and payment history. Errors (including identity theft) can happen and can negatively affect your credit score. Thanks to the Fair Credit Reporting Act (FCRA) you’re legally entitled to one free credit report from each of the major credit bureaus (Equifax, Experian, and TransUnion) at least annually. You can do this via the official site at AnnualCreditReport.com. 

Checking your credit reports on a regular basis helps you catch mistakes early. If you see an error, contact the credit bureau that issued the report to file a dispute. You can also reach out to the creditor that reported the information if you believe it’s inaccurate. Consumer reporting companies usually investigate within 30 days, and may take up to 45 days if you provide additional information. (See AnnualCreditReport.com and CFPB guidance; timelines can vary.)

Maxing out cards

Maxing out your credit card means your balance is close to or at your limit. This can lower your score and cause you to pay more in interest over time.

If you can, postpone big purchases or spread them out so no single card nears its limit. A mid-cycle payment can free up room and lower the balance that gets reported.

Using cash advances

A cash advance is when you borrow cash from your credit card (and some other lending products). Cash advances usually start interest right away and include a separate fee. Life happens. But if you can, try and avoid cash advances if possible. Instead, try and build a small emergency fund so a surprise bill doesn’t push you toward costly cash from a card. If you do find yourself needing a cash advance, make sure to review your card’s cash advance terms first.

Co-signing on a loan or lease for another person 

To co-sign on a personal loan or lease means you agree to pay if the other person doesn’t. Their missed payments can land on your report, too. So it’s important to only co-sign if you trust the borrower and are prepared to take full responsibility for the payments if needed.

Not reading the fine print (terms and conditions)

Annual percentage rate, or APR, is the yearly cost to borrow. Cards can also include late fees, balance transfer fees, and foreign transaction fees. Some credit cards have something called a grace period, which lets you pay your balance in full by the due date to avoid interest charges—though not all cards offer this feature.

It’s important to know, however, that cash advances usually don’t have a grace period, so it’s crucial to read your card agreement so you know your rates, fees, and any grace period rules.

Making big changes before applying for a loan

Closing a credit card or opening new accounts can change your credit score—even right before you apply for a loan. Big shifts like these may affect how lenders view your credit profile for a mortgage, auto loan, or other financing. Keep in mind that lenders can review your credit more than once during the application process, not just at the start.

In the months leading up to a major loan application (like a mortgage for a home), aim to keep your credit activity consistent. Avoid opening or closing accounts unnecessarily, maintain low balances, and continue making on-time payments to reflect stable credit behavior.

Allowing bills to go to collections 

If you’re contacted by a collection agency, you can request written verification of the debt before paying or sharing personal information. Once confirmed, you can work directly with the agency to either pay the outstanding bill or you can dispute the charges. Be cautious of scams; confirm the collector’s identity before sharing personal information.

Not budgeting for all expenses 

Some bills show up only once or twice a year. Without planning, these periodic expenses can throw off your budget and lead to missed payments. List them in advance and save a bit each month so you’re prepared when they arrive.

Opening a store card for a one-time use

Store credit cards often come with high interest rates and low credit limits. A quick discount can get expensive if you carry a balance or open several cards at once. Say yes only if the card fits your spending habits. If you do open one, the best practice is to keep the balance low and pay in full each month.

Dropping a credit report dispute after you file it

A credit report dispute is a formal request to correct an error on your credit report. After you file it, the credit bureau usually investigates within 30 days (or up to 45 if you provide more information). It’s a good idea to keep copies of any letters, forms, and confirmations, and check the status to make sure it’s resolved. If you disagree with the results, you can add a short statement directly to your credit report to explain the item. 

This won’t change your score, and lenders may or may not consider it when reviewing a credit application, but the statement will appear on your credit report for their review.

Complacency

Complacency creeps in when everything looks fine and you stop checking on things. Scores can slip if a bill posts late, a balance creeps up, or a small error lands on your report. Set up a simple routine: Review your credit card and other loan statement(s) monthly and check your credit score and reports on a regular schedule. Turn on alerts for large purchases, credit limit changes, and due dates. A five-minute check each month can help catch small issues before they grow.

Thinking you need to carry a balance to build credit

You don’t have to carry a balance on credit cards to build credit. That’s a myth. Payment history and low credit utilization on revolving credit are what most models reward. Use your card and pay the full statement balance by the due date. That helps to build credit and avoid interest. If you do carry a balance for a short time, make a plan to pay it down and cut back on spending until your balance is in a more manageable place.

Quick credit building checklist

• Turn on autopay and set calendar reminders for yourself.

• Keep utilization under 30% and aim lower when you can.

• Try to pay more than the minimum balance where it makes sense.

• Limit hard inquiries and group rate shopping.

• If it works for you, keep old, no-fee cards open and active.

• Review your credit reports regularly and dispute errors with documentation.

• Try to avoid cash advances and instead begin building a small emergency fund.

• Plan for yearly and seasonal bills.

Pick one habit to improve this week and one to automate next month. Small changes can compound when you make them part of your routine. Check your progress every few weeks and adjust your plan to help your credit and your budget both get stronger.
