Why Credit Score Myths Persist
Credit scores influence some of the biggest financial decisions in your life — mortgage approvals, auto loan rates, even apartment applications. Yet many Americans operate on outdated or simply incorrect assumptions about how scores actually work. Misinformation spreads easily because credit scoring models are complex, and the consequences of a wrong move aren't always immediate. Acting on a myth can quietly drag your score down for months before you realize what happened.
Understanding which beliefs are false — and why — puts you in a far stronger position. The myth-and-fact pairs below address the most common misconceptions, grounded in how the FICO and VantageScore models actually calculate scores. For a broader breakdown of what each credit score tier signals to lenders, see Credit Score Ranges Decoded.
Myth
Checking your own credit score will lower it.
Fact
Viewing your own credit report or score is a soft inquiry and has zero effect on your score.
Credit inquiries fall into two categories: hard and soft. Hard inquiries occur when a lender checks your credit as part of an application decision. Soft inquiries include background checks, pre-qualification reviews, and — critically — when you check your own report. Only hard inquiries can affect your score, and even those typically reduce it by only a few points temporarily. Avoiding self-checks out of fear means missing errors and unauthorized accounts that could cost you far more. For a full breakdown of both inquiry types, see Hard Inquiries vs. Soft Inquiries.
Myth
Closing old or unused credit cards improves your score.
Fact
Closing old accounts can actually hurt your score by reducing available credit and potentially shortening your credit history.
Two key scoring factors are affected when you close a card. First, your total available credit drops, which raises your credit utilization ratio — and higher utilization generally lowers your score. Second, if the closed card is one of your oldest accounts, it can eventually shorten your average account age, another factor in most scoring models. Unless a card carries a fee that no longer makes sense for your situation, keeping it open and lightly used is usually the better move.
Myth
Carrying a small balance on your credit card each month builds credit faster.
Fact
Paying your balance in full every month is just as effective for your score — and it costs you nothing in interest.
This myth may have originated as a misunderstanding of what lenders like to see. What matters for your score is that you use credit and pay on time — not that you carry a revolving balance. Carrying a balance month to month only means you're paying interest, which benefits the card issuer, not your creditworthiness. Paying your statement balance in full by the due date demonstrates responsible use without the cost. If you'd like to understand what each line on your statement actually means, Reading Your Credit Card Statement Without Guessing is a useful reference.
Myth
Shopping around for loan rates will trash your credit score.
Fact
Most scoring models treat multiple loan inquiries for the same type of credit within a short window as a single inquiry.
FICO and VantageScore both recognize that comparing rates for a mortgage, auto loan, or student loan is sensible financial behavior, not risky borrowing. FICO's models typically group similar inquiries that occur within a 45-day window and count them as one. This means you can and should shop for the best rate without worrying that each lender check is stacking up against you. The key is to do your rate shopping within a concentrated timeframe rather than spreading it over several months.
Myth
Your income directly affects your credit score.
Fact
Income is not a factor in any major credit scoring model — your score reflects only how you manage borrowed money.
Credit scores are built entirely from information in your credit report: payment history, amounts owed, length of credit history, credit mix, and new credit inquiries. Income, employment status, savings balances, and net worth are not part of the equation. A high earner with missed payments can have a poor score, while someone with a modest income who pays on time and maintains low balances can have an excellent one. Lenders may consider income separately when evaluating affordability, but that's distinct from your score.
Putting the Facts to Work
Correcting these beliefs is only the first step. The practical moves that protect and build your score are consistent and unglamorous: pay on time, keep balances low relative to your credit limits, and think carefully before opening or closing accounts. Your credit utilization ratio — how much of your available credit you're using — deserves particular attention because it updates monthly and can shift your score noticeably in either direction. For a deeper look at how it's calculated and what to aim for, see Credit Utilization: The Ratio That Quietly Shapes Your Score.
Before applying for any new credit, it's also worth reviewing your report for errors. Inaccurate negative marks are more common than many people expect and can be disputed with the credit bureaus. The Anatomy of a Credit Report walks through each section so you can read yours with confidence.
