Credit Score Myths That Lead Borrowers Astray

Credit inquiries come in two types: soft and hard. A soft inquiry occurs when you check your own score, when a lender pre-screens you for an offer, or when an employer runs a background check. Soft inquiries are invisible to other lenders and do not affect your score at all. A hard inquiry — triggered when you formally apply for new credit — can temporarily reduce your score by a few points. Knowing the difference means you can (and should) monitor your credit regularly without hesitation.

This is one of the most costly myths in personal finance. Scoring models reward you for having available credit and using it responsibly — not for carrying a balance and paying interest. What actually matters is your credit utilization ratio: the percentage of your available revolving credit that you're currently using. Experts generally suggest keeping utilization below 30%, though lower is better. Carrying a balance month-to-month doesn't improve that ratio — it just means you're paying interest unnecessarily. See our deep dive on credit utilization for more detail on managing this key factor.

Closing a credit card doesn't erase its history — but it does affect two important scoring factors. First, it reduces your total available credit, which pushes your utilization ratio higher if you carry any balances elsewhere. Second, once a closed account eventually ages off your report, it shortens the average age of your accounts — a factor that contributes to your score. The five factors that shape your credit score include length of credit history, and older accounts generally help. Unless a card has a fee you can't justify, leaving it open and occasionally using it lightly is usually the smarter move.

FICO and VantageScore — the two dominant scoring frameworks — are built entirely from the data in your credit report, which does not include income. What drives your score is how you manage credit obligations: payment history, amounts owed, length of history, new credit, and credit mix. A high earner who misses payments will have a lower score than a modest earner with a spotless payment record. That said, lenders may separately consider your income when deciding how much credit to extend — but that's a lending decision, not a scoring one.

Payment history is the single most heavily weighted factor in most scoring models, and lenders typically report an account as delinquent once it is 30 days past due. Even one such mark can cause a meaningful score decline — the higher your score before the miss, the steeper the drop can be. The negative entry can remain on your report for seven years, though its impact does diminish over time as your record improves. Our article on what happens when you miss a payment walks through exactly how delinquency is reported and how long the damage lasts.

Equifax, Experian, and TransUnion each maintain their own version of your credit file, and the information across those files isn't always identical. On top of that, multiple scoring models exist — FICO alone has industry-specific versions for auto lending, mortgage, and credit cards. The score a mortgage lender pulls may differ from the one your credit card app shows you. This is why monitoring your full credit report, not just one score, gives you the most accurate picture. Our explainer on score variation across bureaus covers exactly why these gaps exist.
