Why Credit Myths Are So Costly
Credit scores quietly shape some of the most important financial moments in your life — mortgage approvals, auto loan rates, apartment applications, even certain job screenings. Yet a surprising number of widely repeated beliefs about how credit scores work are simply incorrect. Acting on bad information can stall your progress, cost you money in higher interest rates, or lead you to avoid habits that would genuinely help.
This article walks through the most common credit score myths and replaces them with what the evidence actually shows. For a deeper look at exactly how scores are calculated, see our credit score breakdown guide.
Myth
Checking my own credit score will lower it.
Fact
Checking your own credit score is a soft inquiry and has no effect on your score whatsoever.
Credit inquiries come in two types. A hard inquiry occurs when a lender checks your credit as part of a formal application — for a loan, credit card, or mortgage — and can temporarily lower your score by a few points. A soft inquiry includes background checks and, importantly, when you check your own score. Soft inquiries are invisible to lenders and do not affect your score. Regularly reviewing your credit report is encouraged by the Consumer Financial Protection Bureau (CFPB) as a healthy financial habit, and it helps you catch errors or signs of fraud early.
Myth
Carrying a small balance on my credit card each month helps build my credit.
Fact
Paying your balance in full each month is better for your score — and saves you money on interest.
This myth may stem from a misunderstanding of what "using" credit means. Credit scoring models reward you for demonstrating that you can manage credit responsibly, which means making on-time payments — not maintaining a revolving balance. Carrying a balance month to month means paying interest charges with no scoring benefit in return. In fact, a higher balance increases your credit utilization ratio (how much of your available credit you're using), which is one of the most influential factors in your score. Keeping utilization low — generally below 30% of your available limit — is more beneficial. Learn more in our guide to credit utilization.
Myth
Closing old credit cards I no longer use will improve my score.
Fact
Closing old accounts can actually hurt your score by reducing your available credit and shortening your credit history.
Two key credit scoring factors work against closing old cards: credit utilization and length of credit history. When you close a card, you lose that card's credit limit from your total available credit. If you still carry balances on other cards, your utilization ratio rises — and a higher ratio typically means a lower score. Additionally, older accounts contribute to the average age of your credit history, which scoring models treat as a positive signal of experience managing credit. Unless a card carries an annual fee that outweighs its benefit, keeping old accounts open and occasionally using them for small purchases (paid off in full) is generally the better strategy.
Myth
My income directly affects my credit score.
Fact
Income is not a factor in any major credit scoring model, including FICO and VantageScore.
Credit scores are built entirely from information in your credit report, which tracks borrowing and repayment behavior — not earnings. The five standard FICO factors are: payment history, amounts owed (utilization), length of credit history, new credit inquiries, and credit mix. None of these include income. That said, lenders may separately consider your income and debt-to-income ratio when deciding whether to approve you for credit or what rate to offer — but that assessment is theirs, not part of the score itself. This distinction matters: a high earner with poor repayment habits can have a low score, while a modest earner who pays bills on time can have an excellent one.
Myth
A single missed payment won't really matter in the long run.
Fact
A single missed payment can drop your score significantly and remain on your credit report for up to seven years.
Payment history is the single largest component of a FICO score, accounting for approximately 35% of the total. Missing even one payment — especially if you previously had a strong score — can cause a notable drop. According to credit bureau data, a 30-day late payment on a score in the "excellent" range can result in a more significant point drop than the same event on a lower-starting score. The derogatory mark stays on your report for seven years, though its impact diminishes over time as positive payment history accumulates. If you think you might miss a due date, contacting your lender proactively to discuss hardship options is far better than letting a payment go unreported.
What You Can Do With This Information
Understanding how credit scores actually work puts you in control. Instead of avoiding your credit report out of fear or carrying unnecessary balances out of a mistaken belief that it helps, you can make deliberate, informed choices.

Americans with a credit report error
A Federal Trade Commission study found that approximately one in five consumers had an error on at least one of their three major credit reports.

Recommended maximum credit utilization
Most credit experts and the CFPB generally advise keeping your credit utilization ratio below 30% to avoid negative score impacts.
Start by pulling your free credit reports from AnnualCreditReport.com — the federally mandated source — to check for errors and see where you stand. If you're also working to reduce existing debt, our article on why minimum payments cost more than you think explains why paying more than the minimum each month matters. And if a financial setback has already affected your score, practical credit rebuilding strategies outline realistic steps forward.
Don't Ignore Errors on Your Credit Report
Credit report errors are more common than most people expect and can unfairly drag down your score. You're entitled to a free report from each of the three major bureaus — Equifax, Experian, and TransUnion — through AnnualCreditReport.com. If you spot an inaccuracy, you have the legal right to dispute it directly with the bureau. Unresolved errors can affect loan approvals and interest rates, so it's worth checking regularly.
Credit improvement is rarely fast, but it is consistent. The habits that protect and build your score — paying on time, keeping balances low, keeping old accounts open — work steadily in your favor over months and years. Getting the facts straight is the first and most important step.
