Key Takeaways
- Checking your own credit score is a soft inquiry and never lowers your score.
- Carrying a balance on your credit card does not improve your score — it only adds interest costs.
- Closing an old credit card can actually hurt your score by reducing your available credit history.
- Income is not a factor in calculating your credit score under any major scoring model.
- A debit card builds no credit history because it is not a credit product.
Why Credit Score Myths Are So Costly
Credit scores quietly influence some of the biggest financial decisions in your life — mortgage approvals, car loan rates, apartment applications, and sometimes even job offers. Yet a surprising number of Americans navigate this system guided by beliefs that simply do not hold up to scrutiny.
Acting on bad information can mean paying higher interest rates for years, unnecessarily damaging a healthy score, or missing straightforward opportunities to build credit faster. This article examines the most common misconceptions — and replaces them with clear, evidence-based facts.
For a broader look at how these kinds of financial myths take hold, see our piece on budget myths that hold people back.
Myth
Checking your own credit score will lower it.
Fact
Checking your own score is a 'soft inquiry' and has no effect on your credit score whatsoever.
Credit inquiries come in two types: soft and hard. When you check your own score — through a bank app, a free monitoring service, or AnnualCreditReport.com — that is a soft inquiry. Soft inquiries are invisible to lenders and have zero impact on your score. Hard inquiries occur only when a lender formally reviews your credit as part of an application decision, and even those typically reduce a score by only a few points. Avoiding your own credit report out of fear is counterproductive; regular monitoring helps you catch errors and track progress.
Myth
Carrying a small balance on your credit card helps build your score.
Fact
Carrying a balance adds interest charges but provides no scoring benefit — paying in full each month is the better approach.
This myth likely originated from a misunderstanding of credit utilization. Your score does benefit from using your credit card rather than leaving it completely inactive. But that benefit comes from making purchases and having them reported — not from carrying an unpaid balance. Paying your statement in full each month demonstrates responsible use, keeps your utilization ratio low, and avoids interest charges entirely. There is no mechanism in major scoring models that rewards cardholders for carrying debt.
Myth
Closing a credit card you no longer use will improve your score.
Fact
Closing an account can raise your utilization ratio and shorten your credit history, both of which may lower your score.
When you close a credit card, you eliminate that card's available credit limit from your total. If you carry any balances on other cards, your overall credit utilization ratio — the percentage of available credit you are using — immediately rises. Additionally, older accounts contribute to the length of your credit history, which accounts for roughly 15% of a standard FICO score. Closing your oldest card in particular can meaningfully shorten that history over time. Unless a card carries an annual fee you cannot justify, leaving it open and occasionally using it is generally the less risky strategy.
Myth
Your income level directly affects your credit score.
Fact
Income is not a factor in any major credit scoring model, including FICO and VantageScore.
Credit scores are calculated exclusively from information in your credit report — payment history, amounts owed, length of credit history, credit mix, and new credit applications. Your salary, hourly wage, employment status, and net worth do not appear on your credit report and play no role in the calculation. A high earner who misses payments will score lower than a moderate earner who pays consistently on time. Lenders may review income separately when assessing your ability to repay, but that is a distinct step from the credit score itself.
Myth
Using a debit card responsibly helps build your credit score.
Fact
Debit card transactions are not reported to credit bureaus, so they contribute nothing to your credit history.
A debit card draws directly from your bank account. Because no credit is extended and no repayment is required, debit activity is not reported to Equifax, Experian, or TransUnion. Only credit products — credit cards, loans, lines of credit — generate the tradeline data that scoring models evaluate. If you rely primarily on a debit card and want to build credit, a secured credit card or a credit-builder loan are commonly cited starting points, though you should research any product carefully before applying.
Myth
You only have one credit score.
Fact
You have many different credit scores, calculated by different bureaus using different models and versions.
The three major credit bureaus — Equifax, Experian, and TransUnion — each maintain a separate file on you, and those files may contain slightly different information. Scoring companies such as FICO and VantageScore each offer multiple model versions, and lenders choose which version to pull. The number a mortgage lender sees may differ from the number on your bank app or a free monitoring service. This is normal. Focusing on the underlying factors — payment history and utilization above all — matters far more than tracking any single number.
What These Myths Mean for Your Financial Health
Taken together, these misconceptions share a common thread: they make credit management feel more mysterious and fragile than it actually is. The reality is that your score responds predictably to a small set of well-understood behaviors — primarily on-time payments, keeping balances low relative to your credit limits, and letting accounts age.
~1 in 5
Americans with a credit report error
A study by the Federal Trade Commission found that roughly one in five consumers had at least one error on one of their three credit reports.
35%
Of FICO score based on payment history
According to FICO's published scoring model breakdown, payment history is the single largest factor, making on-time payments the most impactful habit.
30%
Of FICO score based on credit utilization
Amounts owed — particularly the ratio of balances to available credit limits — represent the second-largest factor in standard FICO scoring models.
Errors on your credit report can compound the damage caused by misguided habits. Under federal law, you have the right to dispute inaccurate information. Our guide on disputing a credit report error walks through exactly how that process works.

Your Payment History Is the Biggest Lever
No strategy, product, or shortcut matters more than consistently paying at least the minimum due on every credit account before the due date. A single missed payment can remain on your credit report for up to seven years and significantly lower your score. Set up autopay for at least the minimum payment as a safety net, even if you intend to pay in full manually.
