Key Takeaways
Why Credit Myths Are So Costly
Credit scores influence some of the most consequential financial decisions Americans face — mortgage approvals, auto loan rates, apartment applications, and even some job screenings. Yet a surprising number of people manage their credit based on beliefs that have little basis in how scoring systems actually work. Acting on those misconceptions can mean paying higher interest rates, carrying unnecessary debt, or inadvertently damaging the score you're trying to protect.
Understanding what's actually true — and what isn't — is foundational to a healthier financial life. It's also worth clarifying upfront: your credit score and your credit report are two distinct things that serve different purposes. If that distinction isn't clear yet, this breakdown of what each one contains is a useful starting point before diving deeper.
Myth
Checking your own credit score will lower it.
Fact
Viewing your own credit score is a "soft inquiry" and has no impact on your score whatsoever.
Credit inquiries fall into two categories: soft and hard. Soft inquiries — which include checking your own score, background checks by employers, and prequalification reviews — are not visible to lenders and do not affect scoring models. Hard inquiries occur when a lender formally evaluates your application for credit and can cause a modest, temporary dip. Avoiding self-checks out of fear is counterproductive; monitoring your own credit regularly is one of the most recommended habits among financial educators.
Myth
Closing old, unused credit cards is good for your credit.
Fact
Closing old accounts typically lowers your credit utilization ratio and shortens your average account age — both of which can reduce your score.
Credit utilization — the percentage of your available credit that you're using — accounts for a significant portion of most credit scores. When you close a card, that card's credit limit disappears, which raises your utilization ratio if you carry any balances elsewhere. Additionally, scoring models reward longer credit histories. An old card with no annual fee is generally worth keeping open, even if you rarely use it.
Myth
Carrying a small balance each month helps build credit.
Fact
You do not need to carry a balance to build credit. Paying your bill in full each month demonstrates responsible use and costs you nothing in interest.
This myth may have originated from a misunderstanding of what creditors want to see. What matters to scoring models is that you use credit and pay on time — not that you pay interest. Carrying a balance month to month increases your utilization ratio and generates interest charges that provide no credit benefit. Paying in full by the due date is the most cost-effective way to build a positive payment history.
Myth
Your income is factored into your credit score.
Fact
Income is not part of any major credit scoring formula. Scores are based on borrowing and repayment behavior, not earnings.
The major credit scoring models — such as FICO and VantageScore — draw exclusively from information in your credit report: payment history, amounts owed, length of credit history, credit mix, and new credit. Income, employment status, savings, and net worth are not included. Lenders may separately consider income when making approval decisions, but that assessment is distinct from your credit score itself.
Myth
You only have one credit score.
Fact
Consumers have many different credit scores, calculated by different models and different bureaus, which can vary meaningfully.
The three major credit bureaus — Equifax, Experian, and TransUnion — each maintain their own report on you, and those reports may contain slightly different information depending on which creditors report to which bureau. On top of that, multiple scoring models exist (including various versions of FICO and VantageScore), each weighting factors differently. The score a mortgage lender pulls may differ from the score shown by a credit monitoring app. Understanding this helps explain why scores sometimes appear inconsistent across sources.
Habits That Silently Work Against You
Beyond individual myths, certain patterns of behavior compound over time in ways that aren't immediately visible. Missing a single payment, for example, may feel minor — but that derogatory mark can affect your report for up to seven years. Similarly, repeatedly opening new accounts in a short window generates multiple hard inquiries and shortens your average account age, both of which can drag scores down gradually. Some borrowing habits that quietly damage credit over time are worth understanding in detail, especially because they often feel benign in the moment.
Don't Apply for New Credit Before a Major Loan
Each time a lender makes a hard inquiry on your credit, it can cause a small, temporary score decrease. Multiple hard inquiries in a short period — particularly outside rate-shopping windows recognized by scoring models — can add up. If you're planning to apply for a mortgage or auto loan, avoid opening new credit accounts in the months leading up to that application.
If you're approaching a major purchase like a home, credit myths carry an especially high cost. Many prospective buyers either assume their score disqualifies them or expect that a high score alone guarantees approval — neither is accurate. The reality of how credit affects mortgage eligibility is more nuanced than either extreme suggests.
