Key Takeaways
Why Credit Score Myths Are So Costly
Credit scores quietly shape some of the most important financial moments in your life — whether you qualify for an apartment, what interest rate you pay on a car loan, and sometimes even background checks for employment. Yet many people navigate these decisions guided by half-truths passed down from friends or outdated online advice.
Getting the facts straight isn't just academic. Acting on a credit myth can cost you real money or set back years of progress. The myth-and-fact pairs below address the misconceptions we see most often among people starting their financial journey. For a broader foundation, see how credit scores are calculated and why they matter.
Myth
Checking your own credit score will lower it.
Fact
Viewing 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 pulls your credit to evaluate a loan or credit card application — this can temporarily reduce your score by a few points. A soft inquiry occurs when you check your own score, or when a lender pre-screens you for an offer. Soft inquiries are invisible to scoring models. Checking your score regularly is actually a healthy habit that helps you spot errors or unexpected changes early.
Myth
Carrying a small credit card balance each month helps build your credit score.
Fact
You do not need to carry a balance to build credit — paying in full each month is better and costs you nothing in interest.
This myth may have originated from a misunderstanding of how credit utilization works. Scoring models do reward using credit (as opposed to leaving cards completely dormant), but they measure your balance relative to your credit limit — lower is generally better. Carrying a balance month to month doesn't signal responsibility to scoring models; it just means you pay interest. Paying your statement balance in full each cycle keeps utilization low and eliminates finance charges.
Myth
Closing an old credit card you no longer use will help your score.
Fact
Closing an old account typically hurts your score by reducing your total available credit and potentially shortening your credit history.
Two credit score factors are affected when you close an account. First, credit utilization — the percentage of your available credit that you're using — rises when the card's credit limit is removed from the total. Second, if the card is one of your oldest accounts, closing it can eventually shorten your average account age. Both changes tend to lower scores. If a card has no annual fee, keeping it open and using it occasionally for small purchases (then paying in full) is generally the better approach.

Myth
Your income directly affects your credit score.
Fact
Income is not a factor in any of the major credit scoring models — scores are based entirely on how you manage credit accounts.
FICO and VantageScore — the two most widely used scoring frameworks — calculate scores based on payment history, amounts owed, length of credit history, credit mix, and new credit inquiries. Income does not appear on your credit report and is not part of the formula. A high earner who misses payments can have a poor score; someone with modest income who pays on time and keeps balances low can have an excellent one. Lenders may consider income separately when deciding how much to lend, but that's a different step from the score itself. Your credit score reflects your borrowing and repayment behavior — nothing more.
Myth
You only have one credit score.
Fact
You have multiple scores because different bureaus hold different data, and different lenders use different scoring models.
Equifax, Experian, and TransUnion each maintain their own credit files, and creditors are not required to report to all three. As a result, the information across bureaus can differ — and so can the scores produced from each file. On top of that, there are multiple scoring model versions (FICO 8, FICO 9, VantageScore 3.0, and others), and lenders choose which model to use. The score you see through a free consumer service may not be the exact score a specific lender pulls. What matters most is the overall picture: strong payment history, low utilization, and a clean report across all three bureaus. Reading a credit report for the first time walks you through how to review each bureau's file.
What These Corrections Mean in Practice
Knowing the facts is only useful if it changes your behavior. Here are the practical implications of the corrections above:
- Check your reports freely. You are entitled to free reports from all three major bureaus — Equifax, Experian, and TransUnion — through AnnualCreditReport.com. Reviewing them costs you nothing and helps you catch errors. Learn how to read what you find with our guide to reading a credit report for the first time.
- Keep old accounts open when possible. If an old card has no annual fee, leaving it open preserves both your credit history length and your total available credit — two factors that support a stronger score.
- Pay your full balance monthly. This avoids interest charges and keeps your credit utilization low, which scoring models reward.
- Understand what you can and can't control. You can't change your income to affect your score, but you can manage payment timing, balances, and how often you apply for new credit.
Credit scores reward consistent, low-risk behavior over time. Practical habits that support long-term credit health can make a measurable difference without drastic changes. And be aware that some everyday financial moves — like co-signing a loan — can affect your score in ways you might not expect.
