- Closing an old credit card can hurt your score by reducing available credit and shortening credit history.
- Checking your own credit score is a soft inquiry and has zero negative impact on your score.

Why Credit Myths Stick — and Why They're Costly
Credit mythology spreads through well-meaning advice passed between friends and family, often grounded in a partial truth or an outdated understanding of how scoring works. Acting on bad information can cost you real money: unnecessary interest charges, a lower score when you need it most, or missed opportunities to build credit efficiently. This article walks through the most stubborn misconceptions and replaces them with what the data actually shows. For a broader look at related misconceptions, see common credit score myths that affect how people manage their accounts.
Myth
Carrying a balance on your credit card each month helps build your credit score.
Fact
Carrying a balance has no scoring benefit — it only generates interest charges that cost you money.
This is one of the most persistent and costly credit myths. Scoring models like FICO measure whether you use credit responsibly, not whether you pay interest to a lender. What actually matters is your credit utilization ratio — the percentage of your available credit you're using — and whether you pay on time. Paying your statement balance in full each month demonstrates responsible use and costs you nothing extra. Carrying a balance month-to-month only enriches the lender. See how credit utilization works for a deeper look at why lower balances consistently help your score.
Myth
Closing a credit card you no longer use is always a smart, tidy financial move.
Fact
Closing an old card can lower your score by reducing total available credit and potentially shortening your credit history.
When you close a card, two things can happen that hurt your score. First, your total available credit drops, which can push your utilization ratio higher — and higher utilization means a lower score. Second, if that card was one of your older accounts, closing it may eventually reduce the average age of your credit history, another scoring factor. The quiet ways credit actions damage your score often include this one. A better approach: keep the card open with occasional small purchases if there's no annual fee you can't justify.
Myth
Checking your own credit score will lower it.
Fact
Checking your own score is a "soft inquiry" and has absolutely no effect on your credit score.
Credit inquiries come in two types: soft and hard. Soft inquiries — which include checking your own score, pre-approval screenings, and employer background checks — are invisible to lenders and do not affect scoring. Hard inquiries, triggered when a lender formally reviews your credit for a loan or card application, can cause a small, temporary dip. Avoiding self-checks out of fear is counterproductive: monitoring your own report regularly helps you catch errors and identity theft early.

Myth
Once you pay off a debt, it disappears from your credit report immediately.
Fact
Paid accounts — both positive and negative — remain on your credit report for several years after the fact.
Most negative items such as late payments or collections stay on your report for up to seven years from the date of first delinquency. Bankruptcies can linger for up to ten years. The silver lining: positive accounts — loans you paid off in good standing — also stay on your report and continue to benefit your score for years. Paying off a debt is absolutely the right move, but expecting an immediate clean slate leads to frustration. Consistent good behavior over time is what steadily rebuilds credit health.

Myth
A higher income automatically means a higher credit score.
Fact
Income is not a factor in any major credit scoring model. Scores reflect borrowing and repayment behavior only.
Credit scores are calculated from information in your credit report, which covers payment history, amounts owed, length of credit history, credit mix, and new credit inquiries. Your salary, savings account balance, employment status, and net worth are not in your credit report and are not scored. Two people earning vastly different incomes can have identical scores if their credit behaviors match. That said, income does matter to lenders when they evaluate your full loan application — it just works separately from the score itself.
What Good Credit Behavior Actually Looks Like
Once you strip away the myths, the real drivers of a healthy credit score are straightforward: pay on time, keep balances well below your credit limits, avoid opening many new accounts at once, and maintain a mix of account types over time. None of these require carrying debt or paying interest unnecessarily.
35%
Payment history weight in FICO score
According to FICO, payment history is the single largest factor in standard credit score calculations, underscoring why on-time payments matter most.
30%
Credit utilization weight in FICO score
FICO data shows amounts owed — particularly utilization ratio — is the second most influential scoring factor, making balance management critical.
7 years
Typical negative item reporting period
Under the Fair Credit Reporting Act, most negative entries such as late payments and collections remain on a consumer's credit report for up to seven years.
Building strong credit is also closely tied to having a financial safety net. Relying on credit cards as an emergency backup — another common misconception — can lead to high utilization right when you need your score most. Learn more about that overlap in our piece on emergency fund myths that keep people from starting.
Don't Close Cards Right Before Applying for a Loan
Closing a credit card lowers your total available credit, which can raise your utilization ratio and reduce your score in the short term. If you're planning to apply for a mortgage, auto loan, or other major credit product in the near future, hold off on closing accounts until after your application is approved. Even a modest score drop at the wrong moment can affect your interest rate or approval odds.
