Why Credit Score Myths Are So Costly
Credit scores quietly shape some of the most significant financial decisions in a person's life — from mortgage approval to the interest rate on a car loan. Yet a surprising number of widely held beliefs about how scores work are simply wrong. Acting on bad information can mean paying higher interest, losing credit access, or spending years repairing damage that was entirely avoidable.
Understanding what credit scores actually measure is the first step. Your score is built from five weighted categories: payment history, amounts owed, length of credit history, new credit, and credit mix. Misconceptions tend to cluster around all five. See our primer on what credit scores actually measure for a deeper look at each component.
Myth
Carrying a small balance on your credit card each month helps build your credit score.
Fact
Carrying a balance does nothing to improve your score and costs you money in interest charges.
This is one of the most persistent credit myths. The belief is that lenders want to see active borrowing, so leaving a balance shows you're using credit responsibly. In fact, credit scoring models reward low utilization — the less of your available credit you're using, the better. Paying your balance in full each month keeps utilization low and eliminates interest charges entirely. There is no scoring benefit to carrying debt from month to month. If anything, a high balance relative to your limit will pull your score down. Learn more in our guide to minimum payments and long-term debt.
Myth
Closing a credit card you no longer use will improve your credit score.
Fact
Closing an account typically reduces your available credit and can shorten your credit history — both of which may lower your score.
When you close a credit card, two things happen: your total available credit decreases (raising your utilization ratio), and if it's an older account, the average age of your credit history may shorten. Both factors can push your score down. This doesn't mean you should keep accounts open indefinitely — there are valid reasons to close cards, such as high annual fees — but it should be a deliberate decision, not a reflexive one.

Myth
Checking your own credit score will lower it.
Fact
Checking your own credit score is a soft inquiry and has absolutely no effect on your score.
This myth deters people from monitoring their own credit — which is exactly the opposite of what they should do. When you check your own score or report, it registers as a soft inquiry. Soft inquiries are not factored into scoring models at all. Hard inquiries, which occur when a lender evaluates your credit for a new application, can have a modest, temporary impact. Understanding this distinction matters: it means you can — and should — check your credit regularly without concern. Federal law also gives consumers the right to obtain free credit reports from the three major bureaus annually through AnnualCreditReport.com.
Myth
Your income directly affects your credit score.
Fact
Income is not a factor in any major credit scoring model. Your score reflects how you manage debt, not how much you earn.
FICO and VantageScore — the two dominant credit scoring systems — do not use income, employment status, or net worth as inputs. A high earner who misses payments and carries large balances will have a lower score than a modest earner who pays on time and maintains low utilization. This distinction matters when people assume a raise will automatically help their credit, or that low income makes good credit unattainable. Your credit report and score reflect borrowing behavior — not financial success in broader terms.
Myth
One missed payment won't make much of a difference to a good score.
Fact
A single missed payment — especially on a strong credit profile — can cause a significant score drop that may take months to recover from.
Payment history is the single most heavily weighted factor in most scoring models, typically accounting for around 35% of a FICO score. A payment reported 30 or more days late can remain on your credit report for up to seven years. The impact is often more severe for consumers who start with higher scores, because more is at stake. If you've missed a payment, the most important step is to bring the account current as quickly as possible and avoid further missed payments. Consistent on-time payment over time is the most reliable way to rebuild your standing.
How These Myths Can Compound Over Time
The real danger of credit score myths is that their effects accumulate. Closing several old accounts, carrying balances thinking it helps, and avoiding all new credit can push a score down across multiple categories simultaneously. By the time the damage shows up — often when applying for a loan or refinancing — reversing it takes months or longer.

Weight of payment history in FICO score
According to FICO, payment history is the largest single factor in its standard credit scoring model.

Consumers with a credit report error
A Federal Trade Commission study found that approximately one in five consumers had an error on at least one of their three major credit reports.
30%
Recommended maximum credit utilization
Financial educators widely recommend keeping utilization below 30%, though lower ratios generally correlate with higher scores.
Credit utilization is one area where misunderstanding is especially damaging. Many people believe keeping a small revolving balance signals responsible use to lenders. In reality, your utilization ratio — what you owe relative to your total available credit — is most favorable when kept low. Our in-depth guide to credit utilization explains how even one high-balance month can move your score noticeably.
Similarly, the fear of credit inquiries stops many people from rate-shopping or checking their own reports. Understanding the difference between hard and soft inquiries removes that hesitation. Our article on hard vs. soft credit inquiries clarifies exactly when a check affects your score and when it doesn't.
