Why Credit Score Myths Persist

Credit scores shape lending decisions, rental approvals, and sometimes even employment checks — yet widespread misunderstandings about how they work remain stubbornly common. Part of the problem is that credit scoring models are opaque by design: the exact algorithms used by FICO and VantageScore are proprietary. That creates a gap filled by well-meaning but inaccurate conventional wisdom.

Understanding what actually moves your score — and what doesn't — is foundational to sound financial decision-making. For a clear breakdown of what the numbers mean and how scoring categories are constructed, see our guide to credit score ranges and calculations.

Below, we address the most consequential myths, correcting each with what established credit reporting practices and publicly available guidance from the Consumer Financial Protection Bureau (CFPB) and major credit bureaus actually show.

Myth

Checking your own credit score hurts it.

Fact

Checking your own score is a soft inquiry and has no impact on your credit score whatsoever.

Credit inquiries come in two forms: soft and hard. Soft inquiries — which include checking your own score, pre-approval screenings by lenders, and background checks by employers — are invisible to other lenders and carry zero scoring weight. Hard inquiries, by contrast, occur when you formally apply for credit and are visible on your report. Each hard inquiry can temporarily lower your score by a few points. Regularly monitoring your own report is encouraged by financial regulators and carries no downside.

Myth

Closing old credit cards improves your score by cleaning up your history.

Fact

Closing old accounts typically reduces your score by lowering your available credit and shortening your average credit age.

Two significant scoring factors are directly affected when you close a card. First, credit utilization — the ratio of balances owed to total available credit — rises when a credit limit is removed, which signals higher risk. Second, length of credit history accounts for roughly 15% of a FICO score; removing a long-standing account can shorten your average account age. Keeping older accounts open and lightly used is generally better for your score than closing them, even if you rarely use them.

Myth

Carrying a small balance on your credit card each month helps build credit.

Fact

Carrying any balance does not help your score and results in unnecessary interest charges.

This myth likely originated from a misunderstanding of how card activity is reported. What matters for your score is that your card shows usage — a small purchase that you then pay in full demonstrates responsible behaviour without costing you interest. Lenders report your balance to bureaus regardless of whether you paid it off, so a zero balance after full payment still counts as account activity. There is no scoring benefit to carrying a revolving balance, and doing so only benefits the card issuer through interest revenue.

Myth

Co-signing a loan doesn't really affect your credit unless something goes wrong.

Fact

Co-signing makes you equally liable from day one — the loan appears on your credit report and affects your debt-to-income ratio immediately.

When you co-sign, you are not a backup — you are a co-borrower in the eyes of the lender and the credit bureaus. The account appears on your credit report, its balance factors into your utilization and debt load, and every payment — on time or late — is reflected in your score. If the primary borrower misses payments, your score takes the same hit as theirs. Before co-signing, it is worth understanding that you may be held fully responsible for the debt if the primary borrower cannot or does not pay.

Myth

Negative marks fall off your credit report quickly.

Fact

Most negative items, including late payments and collections, remain on your report for seven years; bankruptcies can stay for up to ten.

Under the Fair Credit Reporting Act (FCRA), the standard reporting window for most adverse items is seven years from the date of first delinquency. Chapter 7 bankruptcies remain visible for ten years. While the scoring impact of older negative items diminishes over time — especially as positive history accumulates around them — the item itself doesn't disappear quickly. This is one reason that addressing credit problems promptly, rather than waiting them out, matters. If a negative item appears in error, you can formally dispute it; the CFPB provides a structured process for doing so. Understanding what triggered a score change can help you identify where delinquency-related drops originated.

Protecting Your Score With Accurate Information

Misconceptions don't just lead to inaction — they often lead to actively harmful decisions, like closing accounts to look more responsible or deliberately keeping a balance to appear active. Both strategies backfire.

Myth-Based Decisions Can Cause Lasting Damage

Acting on credit myths — such as closing accounts you think look 'messy' or deliberately carrying a balance — can lower a score that took years to build. Because negative effects can persist for several years and scoring models are not transparent about every input, it is worth verifying assumptions against authoritative sources like the CFPB or your bureau's published guidance before making account management decisions.

Your credit profile is a long-term asset. Actions taken today based on flawed assumptions can leave visible marks for years. If you suspect your report contains inaccurate information — not just a score you disagree with, but a factual error — you have the legal right to dispute it. Our piece on disputing errors on your credit report walks through the formal process step by step.

For readers focused on the long game, maintaining a healthy credit profile over time outlines the consistent habits that support a durable score — grounded in fact, not folklore.

How long most negative marks stay on your report

Under the Fair Credit Reporting Act, most adverse items — including late payments and collections — remain on a consumer's credit report for seven years from the date of first delinquency.

Credit utilization's share of a FICO score

According to FICO's publicly published scoring factor breakdown, amounts owed — which includes utilization ratio — accounts for approximately 30% of a standard FICO score, making it one of the two most influential factors.
