Credit Card Mistakes You Can Fix Today

Credit cards are everywhere, and they are one of the most widely used forms of payment in the US today. Along with the common use and acceptance of credit cards comes the abuse of credit, which leads to debt. The average credit card debt amongst households who are in debt is well over $15,000, according to Federal Reserve consumer credit data. At the high interest rates that credit cards carry — the average APR on new credit card offers has surpassed 20% as tracked by CreditCards.com’s weekly rate report — this amount of money can take years to pay off and can harm your credit for even longer. Part of the problem is that few Americans are taught how to use credit correctly and what having credit means for your future purchases. For example, one in four consumers said they didn’t know how to improve their FICO Score, and nearly half of consumers said they did not know that credit history can determine if you are able to get a new line of credit, according to research published by the Consumer Financial Protection Bureau (CFPB). Using credit doesn’t have to be intimidating and credit can be a powerful tool to help you get the things you need and create a secure financial future. Read on to find my top 5 credit card mistakes that you need to fix today to make sure your finances are secure.

1. Paying only the minimum balance

Paying only the minimum balance is one of the most expensive credit card mistakes you can make. Carrying a balance on a credit card from month to month is very damaging to your credit score. One of the main factors that determine your FICO Score is your credit utilization ratio, or how much of your total available credit from all of your credit cards you use at one time. If you carry a balance over between months your credit utilization remains high, which means you are a riskier account for credit card companies to consider. Most credit experts, including those at Experian, advise that you should avoid using more than 10% of your total available credit at any one time, and that you pay off your balance every month. Not only can you save money on the interest rates that credit cards charge for carrying a balance but you can improve your credit score.

The Real Cost of Minimum Payments

To understand just how damaging minimum payments are, consider a concrete example. If you have a $5,000 balance on a credit card with a 22% APR — close to today’s national average — and you make only the minimum payment of roughly 2% of the balance each month, it could take you over 20 years to pay off that balance and cost you more than $7,000 in interest alone. This is a calculation you can run yourself using tools provided by the CFPB’s credit card repayment calculator. The CARD Act of 2009, enforced by the CFPB, requires credit card companies to disclose exactly how long it will take to pay off your balance if you make only minimum payments — check your monthly statement for this number. It is usually sobering enough to motivate a behavior change.

Strategies to Pay Down Your Balance Faster

Two widely recommended strategies for paying down credit card debt are the avalanche method and the snowball method. The avalanche method, favored by financial planners at firms like SoFi, directs extra payments toward the card with the highest APR first, minimizing total interest paid. The snowball method, popularized by personal finance educator Dave Ramsey, targets the smallest balance first to build psychological momentum. Both methods beat making minimum payments by a wide margin. If your APR is very high, you may also want to consider a balance transfer card that offers a 0% introductory APR period, which can give you breathing room to pay down principal without accruing new interest.

2. Getting a card just for a discount

Opening a retail store credit card just for an upfront discount is a mistake that costs far more than the savings you receive. It seems like every retailer has their own store branded credit card that offers a great discount for signing up. I’ve seen offers for between 10% to 30% off your first purchase when you apply for a store branded credit card. While this seems like a great deal, be very careful about signing up for these cards. Each time you sign up for a credit card there is a hard inquiry on your credit report, and that lowers your total credit score every time a check is run. According to FICO’s official credit education resources, a single hard inquiry typically lowers your score by fewer than 5 points, but multiple inquiries in a short period can have a compounding negative effect. On top of hurting your credit score by signing up, in exchange for a one-time discount many of these cards have very low credit limits and charge very high interest rates — store cards often carry APRs of 25% to 30%, significantly above the national average tracked by Bankrate — even compared to other credit cards. If you really want to take advantage of a discount make sure the purchase you’re making is worth it, for example buying a new stove and not a new sweatshirt, and that you only buy what you can afford to pay off that month or before the interest kicks in.

When a Store Card Can Actually Make Sense

There are limited scenarios where a store-branded credit card offers genuine value. If you are a very frequent shopper at a specific retailer and the card offers ongoing rewards — not just a one-time sign-up discount — the math can sometimes work in your favor. Cards co-branded with major networks like Visa or Mastercard (as opposed to closed-loop store-only cards) also tend to have better terms and can be used anywhere. Always compare the card’s ongoing APR, annual fee, and rewards structure against a general-purpose rewards card from issuers like Chase, American Express, or Capital One before deciding.

3. You close old accounts

Closing old credit card accounts is one of the most counterintuitive credit mistakes — it feels responsible but can actually hurt your score significantly. It might seem odd, but one of the worst things you can do for your credit is to close old credit card accounts. While you might think you’re simplifying your life by closing accounts you don’t need, history of credit is an important factor in determining your FICO Score. The length of your credit history accounts for approximately 15% of your FICO Score, according to FICO’s official scoring breakdown. The older your account is the higher your score will be. If your card has a low or no annual fee it might make sense to leave it alone and just not use the account instead of closing it. However, if you have an older account with a high fee that you no longer use then it might pay off to close it down and take the hit to your credit score instead of paying an unnecessary fee.

How Closing an Account Affects Your Credit Utilization

Beyond credit history length, closing an old account has a second negative effect: it reduces your total available credit, which automatically increases your credit utilization ratio. For example, if you have $20,000 in total available credit across four cards and carry a $2,000 balance, your utilization is 10%. If you close one card with a $5,000 limit, your total available credit drops to $15,000 and your utilization jumps to approximately 13% — with no change in your actual spending behavior. Experian’s credit education team recommends placing a small recurring charge on old accounts — such as a streaming subscription — and setting it to autopay in full each month. This keeps the account active without requiring active management and avoids the risk of the issuer closing the account due to inactivity.

4. You ignore your credit report

Ignoring your credit report is a costly passive mistake — errors and fraud go undetected for months or even years when you’re not looking. Part of keeping a healthy credit score is monitoring your credit report for errors. Identity theft is rampant and increases every year. According to the Federal Trade Commission (FTC)’s Consumer Sentinel Network, identity theft remains one of the most frequently reported consumer complaints in the United States, with hundreds of thousands of cases reported annually. One of the easiest ways to spot identity theft is to keep an eye on your credit card statements online to spot unauthorized transactions and notify the credit card company when you find something that looks wrong. The other way to stay on top of your credit score is to get a free copy of your credit report from AnnualCreditReport.com, the only federally authorized source for free credit reports, which provides you with a free credit report from each of the big three credit bureaus — Equifax, Experian, and TransUnion — once per year to comply with federal law under the Fair Credit Reporting Act (FCRA). Be careful about using other sites as they may require you to enroll in pricey credit monitoring services.

What to Look for When You Review Your Credit Report

When reviewing your credit report from all three bureaus, look specifically for the following red flags: accounts you do not recognize, incorrect personal information (name, address, Social Security number), inaccurate payment history (late payments reported when you paid on time), duplicate accounts, and debts that have passed the statute of limitations but are still being reported. The CFPB provides a step-by-step guide to disputing errors on your credit report, and under the FCRA, credit bureaus are required to investigate disputes within 30 days. Additionally, since 2023, AnnualCreditReport.com permanently allows consumers to access their credit reports weekly — not just once per year — making it easier than ever to stay on top of your credit file throughout the year.

Free vs. Paid Credit Monitoring: What You Actually Need

Many Americans pay for credit monitoring services they don’t need. Free options — including those offered by Chase (Credit Journey), Capital One (CreditWise), and Discover — provide real-time FICO Score tracking and alerts for new inquiries or accounts without any subscription fee. The FDIC and CFPB both recommend starting with free tools before paying for premium services, especially since the core protective action — reviewing your full credit report and disputing errors — is already free under federal law.

5. Opening too many credit cards at once

Opening multiple credit card accounts in a short period sends a negative signal to lenders and can lower your score meaningfully. Having a large amount of available credit is good for your credit score, but opening a lot of accounts at the same time can actually damage your credit. Every time you open a new account the credit card company performs a hard inquiry that is recorded on your credit report with Equifax, Experian, and TransUnion. If a credit card company sees too many hard credit checks then it appears that you are desperate for credit and might be a higher risk for paying your bills on time. According to FICO’s research on credit inquiries, people with six or more hard inquiries on their reports are up to eight times more likely to declare bankruptcy than people with no inquiries — which is why lenders treat clusters of inquiries as a warning signal. While there isn’t a set number of too many cards to open at once or how many cards you should have at any one time, a good rule is to aim for less than 20 accounts overall and not to open more than 2–3 new accounts within a 6-month period.

How Long Do Hard Inquiries Affect Your Credit?

Hard inquiries remain on your credit report for 24 months, but they only affect your FICO Score for the first 12 months, according to FICO. This means the damage is temporary, but it can matter significantly if you are planning a major purchase — such as applying for a mortgage or auto loan — within the next year. A useful strategy if you are planning to apply for multiple cards is to research pre-qualification options, which use soft inquiries that do not affect your credit score at all. Most major issuers including Chase, American Express, Capital One, and SoFi now offer pre-qualification tools on their websites.

The Right Way to Build a Credit Card Portfolio

Building a strategic credit card portfolio takes time and intentionality. Financial advisors generally recommend starting with one strong general-purpose card — ideally one with no annual fee and a reasonable rewards structure — and using it responsibly for at least six to twelve months before opening a second account. As your FICO Score improves and your credit history lengthens, you can strategically add cards that complement your spending patterns. The Consumer Financial Protection Bureau (CFPB) recommends evaluating each new card on three criteria before applying: the APR, the annual fee, and the rewards redemption structure. Never open a card reactively — only open one when it serves a clear purpose in your broader financial plan.

Understanding Your FICO Score: The Five Factors

Before you can fix credit card mistakes, it helps to understand exactly how your FICO Score is calculated. The FICO Score, used by over 90% of top lenders according to FICO, is built from five weighted components. Payment history carries the most weight at 35%, followed by amounts owed (which includes your credit utilization ratio) at 30%. Length of credit history accounts for 15%, credit mix (having both revolving and installment accounts) for 10%, and new credit (including hard inquiries) for the remaining 10%. Every mistake described in this article maps directly to one or more of these five factors, which is why addressing them has such a meaningful impact on your overall financial health.

FICO Score Ranges and What They Mean for Your Borrowing Costs

Your FICO Score determines not just whether you qualify for credit, but at what cost. The difference between a “good” score and an “exceptional” score can translate into thousands of dollars in interest savings over the life of a loan. Here is how FICO Score ranges are generally categorized, along with their real-world implications:

Frequently Asked Questions

What is the biggest credit card mistake people make?

Paying only the minimum balance is the single most costly credit card mistake. At today’s average APR of over 20%, a $5,000 balance paid at the minimum rate can take over 20 years to pay off and cost more than $7,000 in interest. Paying your full statement balance every month eliminates interest charges entirely and improves your credit utilization ratio.

How much does credit utilization affect my credit score?

Credit utilization accounts for approximately 30% of your FICO Score, making it the second-largest factor after payment history. Most credit experts, including those at Experian and FICO, recommend keeping your utilization below 10% for the best score outcomes. Crossing the 30% threshold can noticeably lower your score even if you make all payments on time.

Does closing a credit card hurt your credit score?

Yes, closing a credit card typically hurts your credit score in two ways. First, it reduces your total available credit, which increases your credit utilization ratio. Second, if the account being closed is one of your older accounts, it can lower your average account age, which negatively affects the length-of-credit-history component of your FICO Score. Unless the card carries a high annual fee you can no longer justify, keeping it open and occasionally using it for small purchases is usually the better strategy.

How often should I check my credit report?

You should review your credit report from all three bureaus — Equifax, Experian, and TransUnion — at least four times per year. As of 2023, AnnualCreditReport.com permanently allows weekly free access to all three reports under federal law. Checking your own credit report counts as a soft inquiry and does not affect your FICO Score in any way.

What is a hard inquiry and how much does it lower my credit score?

A hard inquiry occurs when a lender checks your credit report as part of a lending decision, such as when you apply for a new credit card. According to FICO, a single hard inquiry typically lowers your score by fewer than 5 points. However, multiple hard inquiries within a short period can compound the damage and signal financial distress to lenders. Hard inquiries remain on your report for 24 months but only affect your FICO Score for the first 12 months.

Is it worth signing up for a store credit card to get a discount?

In most cases, no. Store-branded credit cards frequently carry APRs between 25% and 30%, well above the national average. The one-time discount — typically 10% to 30% — is rarely worth the hard inquiry on your credit report, the potential for high-interest debt, and the low credit limits these cards usually carry. A narrow exception exists for shoppers who spend heavily at a single retailer and can pay the balance in full each month.

How many credit cards should I have?

There is no single universally correct number, but most financial advisors recommend keeping your total open accounts under 20 and opening no more than 2–3 new cards within any six-month period. The optimal number depends on your ability to track payments, your spending patterns, and your financial goals. What matters most is not the number of cards but how you manage them — on-time payments and low utilization matter far more than card count.

What is the best way to improve my credit score quickly?

The fastest ways to improve your FICO Score are to pay down existing balances to reduce your credit utilization ratio, ensure all future payments are made on time, and dispute any errors on your credit report with Equifax, Experian, and TransUnion. Asking your credit card issuer for a credit limit increase — without increasing your spending — can also immediately lower your utilization ratio. Significant improvements in utilization can reflect in your score within one to two billing cycles.

What is the difference between a FICO Score and a credit score?

FICO Score is a specific brand of credit score created by Fair Isaac Corporation and used by over 90% of top lenders in their credit decisions. “Credit score” is a broader term that also includes scoring models like VantageScore, developed jointly by Equifax, Experian, and TransUnion. While both models use similar data from your credit report, they can produce slightly different numbers. When lenders say “credit score,” they almost always mean FICO Score specifically.

Can identity theft affect my credit score, and how do I protect myself?

Yes, identity theft can severely damage your credit score if a thief opens fraudulent accounts in your name or runs up debt on existing accounts. The fastest protective steps are to regularly check your credit reports at AnnualCreditReport.com, set up transaction alerts through your credit card issuers, and place a free security freeze on your credit file with all three bureaus — Equifax, Experian, and TransUnion — which prevents new accounts from being opened in your name. The FTC’s IdentityTheft.gov provides a personalized recovery plan if you discover you have been a victim.
