Seven Credit Score Myths That Are Actively Costing People Money

Credit score misinformation is unusually persistent. Some myths survive because they sound plausible. Some because acting on them generates revenue for financial companies. Some because they're partially true in one version of a scoring model and people generalize incorrectly. The cost of these myths isn't academic — someone carrying a credit card balance because they believe it helps their score is paying 20% APR for nothing.

Myth 1: Carrying a Small Balance Helps Your Score

False. Paying your credit card balance in full every month produces better scores than carrying a balance. Credit utilization — the percentage of your available credit you're using — is scored at the time the balance is reported, which is typically your statement closing balance. A zero balance at statement close means zero utilization, which is scored favorably. A $50 balance on a $500 card is 10% utilization, which is also scored well. A $200 balance is 40%, which starts pulling the score down. There is no credit score benefit to carrying a balance and paying interest. This myth likely originated from the idea that 'showing activity' requires a balance — activity comes from using the card at all, not from carrying debt forward.

Myth 2: Checking Your Own Credit Hurts Your Score

False. Checking your own credit generates a soft inquiry, which has zero effect on your credit score. Hard inquiries — which do modestly affect your score — only occur when you formally apply for new credit (a credit card, loan, mortgage). Soft inquiries occur when you check your own score, when lenders pre-screen you for offers, and when employers or landlords run background checks. None of these are visible to lenders reviewing your file. Fear of checking your own credit leads people to avoid monitoring their reports for errors, which costs them more in the long run than any inquiry would.

Myth 3: Closing Old Credit Cards Improves Your Score

Usually false. Closing a credit card reduces your total available credit, which raises your utilization ratio if you're carrying balances elsewhere. Closing an old card also potentially shortens your average account age — particularly harmful if it's one of your oldest accounts. A card you never use sitting open with a zero balance contributes positively to your score through available credit and account age. Closing it removes both benefits. The only scenario where closing makes sense: you're paying an annual fee for a card you genuinely won't use enough to justify, and the utilization and age impacts are manageable given your overall file.

Myth 4: You Need to Pay Interest to Build Credit

False. Credit is built through on-time payment history and responsible account management — not through paying interest. Paying your credit card balance in full every month demonstrates exactly the behavior the scoring model rewards: you borrowed, you paid. The fact that you paid before interest accrued is irrelevant to the credit bureau. Many people with 800+ credit scores have never voluntarily paid a dollar of credit card interest.

Myth 5: Your Income Affects Your Credit Score

False. No version of FICO or VantageScore includes income, employment status, savings balance, or net worth. Credit scores are calculated entirely from the data in your credit report — account history, payment behavior, balances, and inquiries. A person earning $200,000 per year with no credit history has no score. A person earning $35,000 with five years of on-time payments and low utilization has an excellent score. This surprises people who assume financial health and credit scores track together. They measure related but separate things.

Myth 6: Paying Off a Collection Removes It From Your Report

Mostly false. Paying a collection account changes its status to 'paid' but does not remove it from your credit report. The derogatory mark remains for seven years from the date of first delinquency on the original account. Newer scoring models (FICO 9, VantageScore 4.0) weigh paid collections less heavily than unpaid ones, so there can be score benefit to paying — but the entry doesn't disappear. The exception is a pay-for-delete agreement, where you negotiate with the collection agency to remove the account from your report as a condition of payment. Bureaus have mixed policies on honoring these, but they do occur. Any pay-for-delete agreement should be in writing before payment is made.

Myth 7: You Have One Credit Score

False. There are three credit bureaus (Equifax, Experian, TransUnion), multiple scoring model brands (FICO, VantageScore), and multiple versions within each brand (FICO 8, FICO 9, FICO 10, industry-specific versions for auto and mortgage lending). Each combination produces a different number. Your scores can vary 20 to 40 points across bureaus even with the same scoring model because the three bureaus don't always have identical data in your file. When a lender pulls your credit, they choose which bureau and which model — and the score they see may not match the one you checked on your app last week.
