Why Credit Myths Are So Costly
Credit scores quietly influence some of the biggest financial decisions in your life — the mortgage rate you qualify for, whether a landlord approves your application, even what you pay for auto insurance in many states. Yet a surprising number of widely circulated beliefs about how scores work are simply wrong.
Acting on bad information can lead to real financial damage: unnecessary interest charges, a lower score than you deserve, or missed opportunities to build credit efficiently. This article addresses the most persistent myths directly, with accurate explanations of how credit scoring actually works.
For a grounding in the fundamentals, see how credit scores are calculated before diving into the myths below.
Myth
Checking your own credit score will lower it.
Fact
Checking your own score is a "soft inquiry" and has absolutely no effect on your credit score.
There are two types of credit inquiries: soft and hard. Soft inquiries — which include checking your own score, pre-approval screenings, and background checks by employers — do not affect your score at all. Hard inquiries occur when a lender reviews your credit as part of an application decision and can temporarily reduce your score by a few points. Avoiding your own credit report out of fear actually works against you, since regular monitoring is one of the best ways to catch errors or signs of fraud early.

Myth
Carrying a small balance on your credit card each month helps build your score.
Fact
Carrying a balance does not improve your credit score — it only costs you interest charges.
This myth is so widespread that many people pay unnecessary interest in the belief they're doing their credit a favor. Credit scores reward on-time payments and low utilization, not the act of carrying a balance. Paying your statement balance in full each month demonstrates responsible credit use, keeps your utilization low, and saves you money on interest. There is no scoring benefit to leaving a balance unpaid. If anything, a growing balance can push your utilization ratio higher, which may actually lower your score.
Myth
Closing a credit card you no longer use will improve your score.
Fact
Closing an old account typically reduces available credit and can shorten your credit history — both of which may lower your score.
When you close a credit card, two things happen that can hurt your score. First, your total available credit decreases, which raises your overall utilization ratio if you carry any balances elsewhere. Second, if the closed card was one of your older accounts, it can eventually reduce the average age of your credit history once it drops off your report — and length of history is a meaningful scoring factor. Keeping a zero-balance card open and occasionally using it for a small purchase is often a better strategy than closing it. If an annual fee is a concern, consider whether a no-fee version of the card is available.
Myth
Your income directly affects your credit score.
Fact
Income is not a factor in any standard credit scoring model. Scores are calculated entirely from credit report data.
Credit scores — including FICO and VantageScore — are built entirely from information in your credit report: payment history, account balances, credit limits, account age, types of credit, and recent inquiries. Your salary, employment status, and net worth appear nowhere in that calculation. A high earner who misses payments will have a lower score than a modest earner who pays on time. This distinction matters because it means income growth alone won't fix credit problems — only changing your credit behavior will.
Myth
There is one universal credit score that every lender sees.
Fact
There are multiple scoring models and three major credit bureaus, so your score varies depending on who is checking and which model they use.
FICO alone has dozens of scoring model versions, and many lenders use industry-specific versions tailored for auto lending or mortgage decisions. VantageScore is another widely used model with its own methodology. Each of the three major credit bureaus — Equifax, Experian, and TransUnion — may also hold slightly different information, leading to different scores even within the same model. This is why the score you see through a free monitoring app may differ from the score a lender pulls. Reviewing your reports from all three bureaus, as outlined in reading your credit report, gives the most complete picture.
The Bigger Picture: What Actually Moves Your Score
Most credit score myths share a common root: people assume the system rewards behaviors it actually doesn't measure, or penalizes actions that are completely harmless. Understanding the real scoring factors — payment history, credit utilization, length of credit history, credit mix, and new inquiries — makes it far easier to see through the noise.
35%
Weight of payment history in a FICO score
Payment history is the single largest factor in standard FICO scoring models, according to FICO's published scoring criteria.
~30%
Weight of credit utilization in a FICO score
Amounts owed — primarily your credit utilization ratio — is the second-largest factor, per FICO's scoring framework.

Major credit bureaus reporting independently
Equifax, Experian, and TransUnion each maintain separate credit files, which is why scores can differ across reports.
Payment history alone accounts for roughly 35% of a standard FICO score. Utilization — how much of your available revolving credit you're using — accounts for about 30%. That means two factors together represent nearly two-thirds of your score, yet both are frequently misunderstood. For a deeper look at the utilization piece specifically, see what credit utilization actually means.
Some habits that feel financially responsible — like closing cards you don't use — can quietly work against you. Others, like checking your own score regularly, are genuinely harmless and encouraged. The everyday behaviors that erode credit health are often the hardest to spot precisely because they seem neutral or even prudent.
Disputed Errors on Your Report Can Be Corrected
If you find inaccurate information on your credit report — a payment incorrectly marked late, an account you don't recognize, or a balance that doesn't match — you have the right to dispute it directly with the credit bureau. Errors are more common than many people realize, and a single mistake can meaningfully suppress your score. The Consumer Financial Protection Bureau (CFPB) provides guidance on the dispute process at consumerfinance.gov.
