Why Credit Score Myths Persist
Credit scores carry enormous weight in American financial life — they influence loan approvals, interest rates, apartment applications, and sometimes even job offers. That kind of power naturally breeds anxiety, and anxiety breeds myth. Many people avoid perfectly harmless actions out of fear of dinging their score.
The problem is that acting on misinformation can actually work against you. Someone who never checks their own credit, for example, may miss errors that are quietly dragging their score down. To understand what genuinely matters, it helps to start with what a credit score actually measures — because most feared actions don't touch the factors that count.
Myth
Checking your own credit score will lower it.
Fact
Checking your own score is a "soft inquiry" and has no effect on your credit score whatsoever.
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 visible on your report but are never factored into your score. A hard inquiry — the kind that can have a small, temporary impact — only happens when you formally apply for new credit. Regularly monitoring your own credit is genuinely encouraged by consumer financial regulators, because catching errors early protects your score.
Myth
Getting rejected for a credit card hurts your credit score.
Fact
A rejection itself has no effect on your score. Only the hard inquiry from applying has any potential impact.
When you apply for a new card, the lender typically runs a hard inquiry, which may temporarily lower your score by a few points. But whether you're approved or denied doesn't change that outcome. The decision made by the lender is never reported to credit bureaus. The small inquiry impact is the same either way, and it generally fades within a year.
Myth
Carrying a small balance on your credit card every month builds credit faster.
Fact
You don't need to carry a balance to build credit. Paying your full balance each month is sufficient — and cheaper.
This myth is remarkably persistent, possibly because it benefits card issuers who collect interest. In reality, scoring models look at whether you're using your credit and paying on time — not whether you're paying interest. Paying your statement balance in full each month demonstrates responsible use and keeps your utilization ratio low, which is a positive signal. Carrying a balance just means paying unnecessary interest charges.
Myth
Closing an old credit card you don't use is always a smart, harmless move.
Fact
Closing an old account can affect your score by reducing your available credit and potentially shortening your average account age.
This is one myth that runs in the opposite direction — the action people assume is neutral can sometimes cause a score dip. When you close a card, you lose that account's credit limit, which can raise your overall utilization ratio if you carry balances on other cards. It can also affect the average age of your accounts over time. That said, the impact varies depending on your full credit profile and may be minor. Keeping an old account open with no balance and occasional use is generally considered the lower-risk approach.
Myth
You need to be in debt to have a good credit score.
Fact
A strong credit score reflects a history of responsible borrowing — not a requirement to carry ongoing debt.
Scoring models reward demonstrated responsible use of credit: on-time payments, low utilization, and a reasonable mix of account types over time. None of that requires carrying a persistent balance or being in debt. Someone who uses a credit card regularly and pays it off in full each billing cycle is demonstrating exactly the behavior that scoring models reward. The goal of credit scoring is to predict reliability — not to measure how much interest you're paying.
What Actually Moves the Needle
The factors that do affect your score — payment history, amounts owed, length of credit history, new credit, and credit mix — are well established. Many of the actions people worry about simply don't appear in those categories at all.
~35%
Payment history's share of a FICO score
According to FICO's published scoring model breakdown, payment history is the single largest factor in your credit score.
~30%
Weight given to amounts owed (utilization)
Amounts owed — including your credit utilization ratio — is the second-largest scoring factor in the standard FICO model.

Americans with a credit report error
A Federal Trade Commission study found that roughly one in five consumers had an error on at least one of their three major credit reports.
For instance, your utilization ratio (the share of your available credit you're using) matters a great deal. But carrying a zero balance, or a very low one, is generally a positive signal, not a warning sign. For a deeper look at how that ratio works, see how credit utilization shapes your score.
It's equally worth understanding which habits genuinely do cause harm. Things like paying late, maxing out cards, or opening several new accounts in quick succession have real consequences — the kind outlined in common credit card habits that quietly damage your finances.
Hard Inquiries Do Have Some Impact
While many feared actions are harmless, hard inquiries — triggered when you formally apply for credit — can temporarily lower your score by a small amount. Multiple hard inquiries within a short window (outside of rate-shopping periods for mortgages or auto loans) can add up. Applying for several new credit accounts at once is worth avoiding if you're planning to take out a major loan soon.
If you're unsure what's currently on your report, reading a credit report without getting lost is a good starting point. And if you spot something that looks wrong, you have the right to dispute it — the process is explained in disputing an error on your credit report.
