Key Takeaways
Why Credit Score Myths Persist
Credit scores quietly influence some of the most consequential financial decisions Americans face — mortgage approvals, auto loan rates, apartment applications, and even some job screenings. Yet a surprising number of people operate on misinformation that can lead to genuinely costly mistakes.
Some myths originate from outdated rules. Others stem from logical-sounding reasoning that simply doesn't match how scoring models actually work. Understanding what credit scores really measure is the foundation for correcting these beliefs. For a thorough breakdown, see our explanation of what credit scores actually measure.
Below, we address the most damaging misconceptions head-on.
Myth
Checking your own credit score will lower it.
Fact
Viewing your own score is a soft inquiry and has zero effect on your credit score.
Credit inquiries fall into two categories: hard and soft. Hard inquiries occur when a lender reviews your credit as part of a borrowing decision — these can shave a few points off your score temporarily. Soft inquiries, which include checking your own score, background checks by employers, and pre-qualification pulls, do not affect your score at all. Avoiding self-checks only keeps you in the dark about your own financial standing.
Myth
Closing old or unused credit cards is a smart way to clean up your credit.
Fact
Closing accounts typically raises your utilization ratio and shortens your credit history — both of which can lower your score.
Your credit utilization ratio compares your total revolving balances to your total available credit. When you close a card, that credit limit disappears from your available total, which can push your utilization higher even if you haven't charged a single additional dollar. Older accounts also contribute positively to the average age of your credit history. Unless a card carries fees you can't justify, leaving it open and occasionally used is usually the better strategy.
Myth
Carrying a small balance on your credit card each month builds your score faster.
Fact
You do not need to carry a balance — or pay interest — to build credit. Paying your statement balance in full is sufficient.
This myth may benefit credit card issuers, but it has no basis in how scoring models work. FICO and VantageScore calculate utilization based on the balance reported to the bureaus — typically your statement balance — not whether you paid it in full. Carrying a balance means paying interest, which costs you money without providing any credit-building benefit. In fact, keeping balances low generally produces better results.
Myth
Your income directly affects your credit score.
Fact
Income, savings, and net worth are not factors in any major credit scoring model.
Credit scores are built entirely from the data inside your credit report — payment history, amounts owed, length of history, types of credit, and new inquiries. Income does not appear in your credit report and plays no role in the score calculation. A high earner with a history of missed payments can have a lower score than someone earning a modest wage who has always paid on time. Income matters to lenders when assessing ability to repay, but that assessment happens separately from the score itself.
Myth
Applying for a mortgage or auto loan at multiple lenders will severely damage your score with many separate hard inquiries.
Fact
Most scoring models treat multiple inquiries for the same loan type within a short window as a single inquiry.
Rate shopping is a normal and financially prudent behavior, and scoring models are designed to accommodate it. FICO models generally group mortgage, auto, and student loan inquiries made within a 45-day window into one inquiry for scoring purposes. The precise window can vary by scoring model version, but the intent is clear: consumers should be able to compare offers without penalty. Don't let fear of inquiry stacking stop you from finding a competitive rate.
What These Corrections Mean for Your Financial Decisions
The five factors that drive your credit score — payment history, credit utilization, length of credit history, credit mix, and new inquiries — each carry different weight. Misunderstanding how any one factor works can lead to decisions that backfire. Our guide to the five factors that shape your credit score explains each one in depth.
1 in 5
Americans with a credit report error
According to a Federal Trade Commission study, approximately one in five consumers had an error on at least one of their three major credit bureau reports.
30%
Of your FICO score tied to credit utilization
The 'amounts owed' category, which includes utilization, accounts for roughly 30% of a standard FICO score calculation.
35%
Of your FICO score tied to payment history
Payment history is the single largest factor in a FICO score, underscoring why on-time payments have an outsized impact.
Credit utilization deserves particular attention because it responds quickly to changes in your balance or credit limit. Learn more about why credit utilization matters more than you think. Similarly, if you want to know exactly when a credit check will or won't affect your score, see our detailed breakdown of hard inquiries vs. soft inquiries.
Errors on Your Credit Report Can Cost You
Because your score is built directly from your credit report, inaccurate information can depress your score without any fault of your own. You're entitled to a free credit report from each of the three major bureaus — Equifax, Experian, and TransUnion — through AnnualCreditReport.com. Reviewing your report regularly lets you dispute errors before they affect a loan application or interest rate.
