Credit Myths That Keep People From Improving Their Scores

This is one of the most costly myths in personal finance. Credit scoring models — including FICO and VantageScore — reward you for using credit and paying it back responsibly. They do not reward you for paying interest. Carrying a balance simply means the card issuer earns interest revenue from you; it does nothing positive for your score. In fact, a lingering balance raises your credit utilization ratio, which is the share of your available revolving credit that you're using. High utilization can lower your score. Paying in full by the due date is the financially optimal move on both fronts.

Credit inquiries fall into two categories. A hard inquiry occurs when a lender pulls your credit to make a lending decision — applying for a mortgage, auto loan, or new credit card. Hard inquiries can cause a modest, temporary dip. A soft inquiry occurs when you check your own report, when an employer runs a background check, or when a card issuer does routine account monitoring. Soft inquiries do not affect your score at all. You can check your reports at AnnualCreditReport.com without any scoring consequence. Regular monitoring is actually recommended — it's the best way to spot errors or signs of identity theft early. See Credit Reports and Credit Scores: Two Different Things for more on how these tools work together.

When you close a credit card, two things happen that can hurt your score. First, your total available revolving credit drops, which immediately increases your utilization ratio if you carry any balances on other cards. Second, if the closed card was one of your older accounts, it may eventually reduce the average age of your credit history — a factor that scoring models weigh. There are valid reasons to close an account, such as a card with a high annual fee you can't justify. But closing a no-fee card simply because you rarely use it rarely benefits your score and often harms it.

FICO's scoring model groups mortgage, auto, and student loan inquiries made within a 45-day window into a single inquiry for scoring purposes. Older FICO versions use a shorter 14-day window. VantageScore applies a similar approach. This design exists specifically to encourage consumers to comparison shop without penalty. Getting quotes from several lenders for a mortgage or car loan is a sound financial practice — and the credit system is built to accommodate it. The myth discourages borrowers from finding better terms, which serves no one except lenders who avoid competition.

FICO and VantageScore do not consider income, employment status, net worth, or assets when calculating your score. The factors that matter are payment history, amounts owed (including utilization), length of credit history, credit mix, and new credit inquiries. A high earner who misses payments and maxes out cards will have a lower score than someone with a modest income who pays on time and keeps utilization low. Lenders do consider income separately — during the underwriting process — but that is distinct from your credit score.
