Key Takeaways
Why Credit Myths Are So Persistent
Credit is one of those subjects where a little knowledge can be dangerous. Half-heard advice, outdated rules, and well-meaning but inaccurate tips from friends and family all feed a surprisingly stubborn set of misconceptions. The cost isn't trivial: acting on bad credit information can raise your interest rates, delay a mortgage approval, or keep you paying unnecessary fees for years.
The good news is that the truth about credit is less complicated than the myths suggest. The five corrections below cover the beliefs we encounter most often — ones that personal finance educators regularly dispute as well.
79%
Americans with at least one credit report error
A Federal Trade Commission study found that roughly 1 in 5 Americans had an error on at least one of their three major credit reports.
35%
Share of FICO score from payment history
Payment history is the single largest factor in the standard FICO scoring model, according to FICO's published methodology.
7 years
How long most negative marks stay on your report
Under the Fair Credit Reporting Act, most derogatory items must be removed from your credit report after seven years from the original delinquency date.
The Myths — and What's Actually True
Each misconception below is paired with an accurate correction and a brief explanation of how the underlying mechanics actually work. Take note of any beliefs you've held yourself — adjusting your habits based on accurate information is one of the most straightforward ways to protect and improve your credit profile.
Myth
Checking my own credit score will lower it.
Fact
Checking your own score is a soft inquiry and has zero effect on your credit score.
This myth keeps many people from monitoring their own credit — which is one of the most useful financial habits you can build. Under the Fair Credit Reporting Act, you're entitled to a free report from each of the three major bureaus annually. Reviewing it regularly helps you catch errors early. See our guide to disputing credit report errors if you find something inaccurate.
Myth
You need to carry a balance to build good credit.
Fact
Paying your balance in full each month is better for your score and costs you nothing in interest.
This is one of the most costly myths in personal finance. Carrying a balance generates interest charges without providing any scoring benefit. What actually helps is using the card regularly and paying on time. Credit utilization — how much of your available credit you're using — is a key scoring factor, and keeping it low (generally below 30%) is more beneficial than maintaining a running balance.
Myth
Closing an old credit card you don't use is always a smart move.
Fact
Closing old accounts can reduce your available credit and shorten your credit history, potentially lowering your score.
An old card with no annual fee and a clean payment history is often worth keeping open, even if you rarely use it. It contributes to a longer average account age and keeps your total available credit higher — both factors in your score calculation. If a card carries a fee that no longer makes sense, contact the issuer to ask about product changes before closing it outright.
Myth
A low income means a low credit score.
Fact
Income is not a factor in any major credit scoring model — your score reflects borrowing behavior, not earnings.
Credit scores are calculated from data in your credit report: payment history, amounts owed, length of credit history, new credit, and credit mix. Your salary, hourly wages, or household income don't appear in that report and don't factor into your score. That said, income does matter to lenders when they assess your overall ability to repay — it's just a separate consideration from the score itself.

Myth
Bad credit follows you for life.
Fact
Most negative items — including late payments and collections — are removed from your credit report after seven years.
While serious derogatory marks do significant short-term damage, they are not permanent. Chapter 7 bankruptcy is the longest-lasting item, staying for up to 10 years. For most other negative entries, the clock starts from the date of the original delinquency. During the waiting period, consistent on-time payments and responsible credit use can meaningfully rebuild your profile. Building credit from scratch uses many of the same techniques.
Soft vs. Hard Inquiries: Know the Difference
When you check your own credit report or score, it registers as a soft inquiry and has no effect on your score. Hard inquiries — triggered when a lender reviews your credit for a loan or card application — can cause a small, temporary dip. Understanding this distinction can save you from avoiding a free check that's actually in your best interest.
What You Can Actually Do to Help Your Score
Now that the myths are out of the way, the real levers are simpler than most people expect. Payment history accounts for the largest share of your score, so consistent on-time payments matter most. Keeping your credit utilization low — ideally under 30% of your available limit — is the second most controllable factor. If you're only paying the minimum each month, understand that you're extending your debt and accruing interest without meaningfully improving your standing.
Beyond that, avoid applying for multiple new accounts in a short window, keep older accounts open when practical, and review your credit report at least once a year for errors. If you find a mistake, the dispute process is more straightforward than many people assume.
Don't Close Old Accounts Without Thinking First
Closing a long-standing credit card removes its credit limit from your available credit, which can raise your overall utilization ratio and reduce the average age of your accounts — both of which may lower your score. Before closing an old card, weigh the impact carefully, especially if you're planning a major loan application soon.
