Key Takeaways
- Checking your own credit score does not lower it — that's a soft inquiry, not a hard one.
- Carrying a credit card balance month-to-month does not help your score and costs you interest.
- Closing old credit cards can actually hurt your score by shrinking your available credit.
- Income has no direct effect on your credit score; only borrowing behavior is measured.
- A single missed payment can significantly damage your score, especially if 30 or more days late.
Why Credit Score Myths Persist
Credit scores govern your ability to borrow money, rent an apartment, and sometimes even land a job — yet the rules that govern them are widely misunderstood. Some myths spread because the scoring system is genuinely opaque. Others survive because a half-truth contains just enough logic to feel right. The result is that many Americans manage their credit based on advice that is factually wrong and often quietly harmful.
This article corrects the most common misconceptions using the actual mechanics behind widely used scoring models like FICO and VantageScore. For a foundational understanding of how scores are calculated and what the ranges mean, see Credit Scores Decoded. The myth-and-fact breakdowns below will help you stop leaving points on the table.
Myth
Checking your credit score hurts it.
Fact
Checking your own score is a "soft inquiry" and has zero effect on your credit score.
There are two types of credit inquiries: soft and hard. Soft inquiries — including checking your own score, pre-qualification checks by lenders, and background checks — are invisible to scoring models and cause no damage. Hard inquiries occur when a lender formally reviews your credit after you apply for a loan or card; these can lower your score by a few points temporarily. Avoiding your own score out of fear only keeps you uninformed. Monitoring it regularly is one of the simplest things you can do for your credit health.
Myth
You need to carry a balance to build credit.
Fact
Carrying a balance costs you interest and provides no scoring benefit over paying your bill in full each month.
This myth likely stems from confusing "using credit" with "carrying debt." Scoring models reward responsible use of credit — meaning you charge something and pay it back — not the act of paying interest. In fact, carrying a high balance month to month increases your credit utilization ratio, which can lower your score. The most effective strategy is to charge only what you can pay off in full each billing cycle. To understand just how much utilization affects your number, see Credit Utilization: The Ratio That Moves Your Score.
Myth
Closing a credit card you don't use is smart financial housekeeping.
Fact
Closing a card reduces your available credit and can raise your utilization ratio, potentially lowering your score.
Your credit utilization is calculated as your total balances divided by your total available credit limits across all accounts. When you close a card, you eliminate that card's credit limit from the denominator, which pushes your utilization percentage higher — even if your spending stays the same. Closing an older card also reduces the average age of your credit accounts, which is another scoring factor. Unless a card carries an annual fee that outweighs its benefit, keeping it open with minimal use is generally the better move.
Myth
Your income directly affects your credit score.
Fact
Income is not a factor in any major credit scoring model; scores measure borrowing and repayment behavior only.
FICO and VantageScore calculate your score based on five categories of credit behavior: payment history, amounts owed (including utilization), length of credit history, new credit, and credit mix. Income appears nowhere in this formula. A high earner who misses payments and maxes out cards will have a lower score than a modest earner who pays on time and maintains low balances. Lenders may separately ask about income when evaluating a loan application, but that figure does not feed into the score itself.
Myth
A missed payment only matters if you're really late — like several months behind.
Fact
A single payment that reaches 30 days past due can be reported to credit bureaus and cause a significant score drop.
Payment history is the single largest factor in most scoring models, typically accounting for about 35% of a FICO score. The moment a payment crosses the 30-day-late threshold, a creditor may report it as delinquent, and that mark can remain on your report for up to seven years. The damage is most severe on scores that were previously strong — a borrower with excellent credit can lose significantly more points than someone whose score was already low.

Behaviors That Quietly Work Against You
Beyond the big myths, there are subtler habits that erode credit over time without triggering an obvious alarm. Applying for multiple new accounts in a short window generates several hard inquiries simultaneously, which can compound into a meaningful dip. Letting a card sit completely unused for long periods may lead the issuer to close it for inactivity — shrinking your available credit and potentially your score. And disputing legitimate information on your report, rather than genuine errors, wastes time and accomplishes nothing; scoring models only reflect what's accurately reported.
Don't Confuse Accurate Entries With Errors
Negative items that are accurate — a genuine late payment, a legitimate collection account — cannot be removed through a dispute. Attempting to dispute truthful information is not a valid credit repair strategy and will not succeed. Focus your energy on building positive habits going forward rather than trying to erase a factual history. If you find information that is genuinely inaccurate, that is worth disputing immediately.
If you suspect your report contains inaccurate information — not just unfavorable but accurate entries — that's a separate and important process. Our guide What to Do If Your Credit Report Has an Error walks through disputing genuine mistakes with the major bureaus.
