Key Takeaways
- Checking your own credit score is a soft inquiry and never lowers your score.
- Carrying a credit card balance from month to month does not help your credit score.
- Closing an old credit card can actually hurt your score by reducing available credit history.
- Income has no direct effect on your credit score calculation.
- Even a single missed payment can significantly damage an otherwise strong credit score.
Why Credit Score Myths Persist
Credit scores quietly shape some of the biggest financial decisions in American life — from whether you qualify for a mortgage to what interest rate you pay on a car loan. Yet widespread misconceptions about how scores actually work remain stubbornly common. Some of these myths are harmless misunderstandings. Others can lead people to make decisions that actively damage their credit over time.
Understanding what your credit score is actually measuring — payment history, credit utilization, account age, credit mix, and new inquiries — is the foundation for busting every myth below. The score is a mathematical model, not a judgment call, which means it responds predictably to specific behaviors. That's good news: once you know the real rules, you can work with them.

The Most Damaging Credit Score Myths, Corrected
The myths below are among the most widely repeated — and in many cases, the most costly to believe. Each one misrepresents how credit scoring models actually work.
Myth
Checking your own credit score will lower it.
Fact
Checking your own score is a 'soft inquiry' and has zero effect on your credit score.
Credit inquiries come in two forms. A hard inquiry occurs when a lender pulls your report to evaluate a credit application — this can temporarily lower your score by a few points. A soft inquiry occurs when you check your own score, or when a lender pre-screens you for an offer. Soft inquiries are invisible to other lenders and do not affect your score at all. Avoiding your own credit report out of fear of hurting it means missing opportunities to catch errors or track your progress.
Myth
Carrying a small balance on your credit card helps build credit.
Fact
Paying your balance in full each month is better for your score than carrying a balance — and it saves you money in interest.
This myth likely stems from a vague idea that showing 'activity' on a card is good. In reality, credit scoring models reward low utilization — the ratio of your balance to your credit limit. Carrying a balance raises your utilization, which can lower your score. It also means paying interest charges with no scoring benefit. Paying in full each month demonstrates responsible use without costing you anything extra.
Myth
A higher income leads to a higher credit score.
Fact
Income is not a factor in any major credit scoring model. A high earner with missed payments can have a lower score than a modest earner with a clean payment history.
FICO and VantageScore — the two dominant scoring systems — draw exclusively on information in your credit report. That report contains your payment history, current balances, account ages, credit types, and recent inquiries. It contains nothing about salary, savings, or employment. This is why someone who earns a high income but has a history of late payments can have a surprisingly low score, while someone with a modest income and disciplined repayment habits can have an excellent one.
Myth
Closing a credit card you don't use improves your credit score.
Fact
Closing an account typically lowers your score by reducing your available credit and potentially shortening your average account age.
When you close a credit card, two things happen that can hurt your score. First, your total available credit drops, which increases your utilization ratio if you carry any balances on other cards. Second, if the closed card was one of your older accounts, your average account age may decrease. Account age is a meaningful factor in scoring models — longer histories generally signal lower risk. An unused card with no annual fee is often worth keeping open simply to preserve these benefits.
Myth
You only have one credit score.
Fact
You have many credit scores. Different lenders use different scoring models, and each credit bureau may produce a different result.
FICO alone has dozens of scoring versions, and VantageScore has its own separate models. A mortgage lender, auto lender, and credit card issuer may each pull a different version of your score — and each of the three major credit bureaus (Equifax, Experian, and TransUnion) may have slightly different information in your file, leading to different scores from the same model. The number you see on a free monitoring app is a useful reference point, but it may not be identical to what a specific lender sees.
Myth
Missing one payment won't matter much if your overall history is good.
Fact
A single missed payment — particularly a recent one — can cause a significant score drop, even for people with strong credit histories.
Payment history is the single largest factor in most credit scoring models, typically accounting for roughly 35% of a FICO score. A payment reported as 30 or more days late can lower a high score by a substantial amount, and recent delinquencies carry more weight than older ones. The better your score before the missed payment, the sharper the potential drop. Late payments can remain on your credit report for up to seven years, though their impact typically diminishes over time as you build a positive record afterward.
Credit utilization deserves special attention because it is one of the most actionable factors in your score. Our deeper look at how credit utilization affects your score explains exactly how to calculate your ratio and why keeping it low matters more than most people realize.
If you've ever considered closing an account you rarely use, it's worth reading about why closing an old credit card can hurt your score before you do. The effect on your average account age and total available credit can be more significant than expected.
What Actually Moves Your Score — and What Doesn't
Knowing what credit scores ignore is just as useful as knowing what they track. Your income, net worth, employment status, and savings account balances play no direct role in your FICO or VantageScore calculation. Two people with identical credit histories but very different salaries will have the same score. This surprises many people, but it follows logically from the score's purpose: it predicts the likelihood of repaying debt on time, not overall financial health.
35%
Weight of payment history in FICO score
According to FICO's published scoring breakdown, payment history is the single largest factor — making on-time payments the highest-leverage habit for most people.
~1 in 5
Americans with a credit report error
A study by the Federal Trade Commission found that approximately one in five consumers had an error on at least one of their three major credit bureau reports.
30%
Recommended maximum credit utilization
Financial guidance commonly suggests keeping your credit utilization ratio at or below 30%, though lower is generally better for your score.
It's also worth knowing that errors on your credit report — which are more common than most consumers expect — can drag down a score through no fault of the account holder. Reviewing your reports periodically and understanding how to spot and correct credit report errors is a straightforward step that costs nothing.
Finally, if you want to understand the practical stakes attached to each score range — what lenders typically see when they look at your number — the credit score range explained walks through what each tier means in real-world terms. Myths about credit scores often persist because the system feels opaque. The antidote is simply knowing how it works.
