From checking your own score to closing old cards — separate widely believed credit myths from what the evidence actually shows.
Key Takeaways
- Checking your own credit score is a soft inquiry and never lowers your score.
- Closing an old credit card can actually hurt your score by reducing available credit.
- Carrying a small balance does not improve your score — paying in full is better.
- Income is not a factor in FICO or VantageScore credit scoring models.
- Multiple rate-shopping inquiries within a short window are typically counted as one.
Why Credit Myths Persist — and Why They're Costly
Credit scores quietly influence some of the most significant financial decisions in a person's life — mortgage approvals, auto loan rates, and even rental applications. Yet a surprising number of widely repeated beliefs about how scores work are simply wrong. Acting on bad information can cause real harm: people avoid checking their own score out of fear, keep debt on purpose thinking it helps, or close old accounts at exactly the wrong moment.
This article separates the most persistent myths from what the evidence actually shows. For a broader foundation, see the comprehensive guide to debt and credit covering everything from score mechanics to repayment strategies.
Myth
Checking your own credit score will lower it.
Fact
Checking your own score is a soft inquiry and has zero effect on your credit score.
Credit inquiries fall into two categories: hard and soft. Hard inquiries occur when a lender reviews your file as part of a credit application — these can have a small, temporary impact on your score. Soft inquiries include background checks, pre-approval screenings, and any time you review your own report. Soft inquiries are never factored into scoring models. Avoiding self-checks out of fear is counterproductive — you can't manage what you don't monitor.
Myth
Closing old credit cards you don't use is good for your credit.
Fact
Closing an old account typically reduces available credit and can raise your utilization ratio, potentially lowering your score.
Two scoring factors are affected when you close a card: your credit utilization ratio increases (less available credit means existing balances represent a larger percentage), and the average age of your accounts may decrease over time as the closed account eventually ages off your file. Both changes can work against your score. If you're concerned about an unused card, consider making a small periodic purchase and paying it off rather than closing the account outright — particularly if it's one of your older accounts.
Myth
Carrying a small balance each month helps build your credit score.
Fact
There is no scoring benefit to carrying a balance. Paying in full is better — it demonstrates responsible use and costs you nothing in interest.
This myth may have originated from a misunderstanding of what "activity" means to lenders. Scoring models reward on-time payments and low utilization — not the act of maintaining a revolving balance. Deliberately leaving a balance means paying interest for no credit benefit whatsoever. The only entity that benefits from this belief is the card issuer collecting that interest.
Myth
Your income directly affects your credit score.
Fact
Income is not a factor in FICO or VantageScore models. Your score reflects borrowing and repayment behavior, not earnings.
FICO scores are calculated using five categories: payment history, amounts owed (utilization), length of credit history, credit mix, and new credit. Income does not appear in any of these categories. A high earner who misses payments can have a low score; a modest earner with consistent on-time payments and low utilization can have an excellent one. Lenders may separately consider income when evaluating ability to repay, but that is a distinct step from the score itself.
Myth
Rate-shopping for a mortgage or auto loan will seriously damage your score.
Fact
Scoring models treat multiple inquiries for the same loan type within a short window as a single inquiry to encourage informed shopping.
Both FICO and VantageScore are designed to distinguish rate-shopping from risk-taking. When multiple mortgage or auto loan inquiries occur within approximately 14 to 45 days (the exact window varies by scoring model version), they are typically consolidated and counted as one. The practical implication: getting quotes from several lenders to compare rates is not only safe — it's financially wise. Overpaying on a rate to avoid a minor, temporary score dip would almost never make financial sense.
Myth
You need to be in debt to have a good credit score.
Fact
You don't need to carry debt — you need a demonstrated history of managing credit responsibly, which can be done at minimal or no cost.
A common misconception is that you must borrow money and repay it over time to build a strong score. In reality, using a credit card for regular purchases and paying the balance in full each month creates a positive payment history and keeps utilization low — two of the most influential scoring factors — without requiring you to carry or pay interest on any debt. A secured credit card or a credit-builder loan can serve a similar function for those establishing credit from scratch.
How Inquiries and Applications Actually Affect Your Score
Fear of credit inquiries stops many people from rate-shopping or even monitoring their own file. That fear is largely misplaced, but understanding the difference between inquiry types matters. For a clear breakdown, see hard inquiries vs. soft inquiries on your credit file.
5 factors
Components of a FICO credit score
FICO scores are built from payment history, amounts owed, length of credit history, new credit, and credit mix — income is not among them.
~14–45 days
Rate-shopping window for consolidated inquiries
FICO and VantageScore models generally consolidate multiple mortgage or auto inquiries made within this period into a single inquiry for scoring purposes.
35%
Payment history share of FICO score
Payment history is the single largest factor in the standard FICO scoring model, making on-time payments the most direct path to score improvement.
One related misconception worth flagging: some consumers believe opening a new account is always harmful. A new account does trigger a hard inquiry and temporarily lowers the average age of your accounts — both small negative factors. But if it meaningfully increases your total available credit, the utilization benefit can outweigh those short-term dips over time. Context matters.
Utilization, Balances, and the Debt You Carry
Credit utilization — the percentage of your available revolving credit that you're currently using — is one of the most actionable levers in your score. Keeping it low (many credit educators suggest staying under 30%, though lower is generally better) can make a meaningful difference. For a deeper look at how this ratio is calculated and why lenders watch it closely, see credit utilization: the ratio that quietly shapes your score.
Utilization Can Change Quickly — in Both Directions
Because credit utilization is calculated from your current balances at the time your issuer reports to the bureaus, it can shift significantly from month to month. Paying down a balance before your statement closing date can lower the utilization figure that gets reported. Conversely, a large purchase — even one you intend to pay off — can temporarily spike your reported utilization if the timing is off. If you're planning to apply for credit soon, timing your payments carefully can matter.
One directly related myth — that carrying a small balance improves your score — leads consumers to pay unnecessary interest. The evidence does not support this. Paying your statement balance in full demonstrates responsible use without costing you anything in interest. For more on what that interest actually costs month to month, see the real cost of carrying a credit card balance.

Don't Let Myths Delay You From Reviewing Your Report
Under federal law, consumers in the US are entitled to a free credit report from each of the three major bureaus annually through AnnualCreditReport.com. Errors on credit reports — incorrect late payments, accounts that don't belong to you — can suppress your score. Reviewing your report regularly is one of the most effective and cost-free steps you can take toward stronger credit health. Disputing inaccuracies is a formal process each bureau is required to support.
