Why Credit Myths Are Surprisingly Costly
Credit scores influence loan approvals, interest rates, rental applications, and sometimes even job offers. Yet many Americans navigate this system armed with information that is simply wrong. Acting on a credit myth can mean paying hundreds — or thousands — more in interest, or being denied credit when you actually qualify. This article tackles the most persistent misconceptions head-on, drawing on how credit scoring actually works under the FICO and VantageScore models used by most U.S. lenders.
For a broader foundation, see our complete guide to managing debt and credit. And if you want to understand exactly what that three-digit number means before diving into myths, Credit Scores Demystified is a good starting point.
Myth
You need to carry a balance on your credit card each month to build a good credit score.
Fact
Carrying a balance has no scoring benefit — it only generates interest charges. Paying your statement balance in full each month is the better move.
This is one of the most expensive myths in personal finance. Credit scores reward on-time payment history and low utilization — not the act of carrying debt. FICO's scoring model does not distinguish between a balance you paid in full and one you rolled over; it simply records whether you paid on time and how much of your available credit you're using. Carrying a balance increases your utilization ratio if it reports high, which can actually lower your score. The only guaranteed outcome of carrying a balance is interest expense.
Myth
Closing credit cards you no longer use will clean up your credit profile and help your score.
Fact
Closing accounts typically reduces your total available credit and can shorten your credit history — both of which may lower your score.
Two important scoring factors are credit utilization (the percentage of available credit you're using) and length of credit history. When you close a card, you lose that card's credit limit from your total available credit, which can push your utilization ratio higher even if your balances stay the same. If the closed card was one of your older accounts, it may also shorten your average account age over time. Before closing an account, weigh those potential score impacts — especially if a loan application is on the horizon. For more on subtle score damage, see habits that quietly damage a credit score.
Myth
Checking your own credit score or credit report will hurt your score.
Fact
Checking your own credit is a "soft" inquiry and has absolutely no effect on your score. Only "hard" inquiries from lenders can cause a small, temporary dip.
Credit inquiries come in two types. A soft inquiry occurs when you check your own report, when a lender pre-screens you for an offer, or when an employer runs a background check — none of these affect your score. A hard inquiry occurs when you apply for new credit and a lender pulls your full report; this can reduce your score by a few points temporarily. Avoiding your own credit report out of fear of damage means missing the chance to catch reporting errors, which the Consumer Financial Protection Bureau (CFPB) notes are more common than many consumers realize.
Myth
A higher income means a higher credit score.
Fact
Income is not a factor in any mainstream credit scoring model. Your score is based on borrowing and repayment behavior, not how much you earn.
FICO and VantageScore do not use income, employment status, or net worth as inputs. What they do use: payment history, amounts owed, length of credit history, credit mix, and new credit. A high earner who misses payments will have a lower score than a moderate earner who pays consistently on time. Lenders may consider income separately when evaluating your ability to repay, but that is a different calculation from your credit score itself.
Myth
Once you pay off a collection account, it disappears from your credit report immediately.
Fact
A paid collection account generally remains on your credit report for up to seven years from the original delinquency date, though its impact on your score may diminish.
Under the Fair Credit Reporting Act (FCRA), most negative items — including collections — can remain on your credit report for seven years. Paying the debt changes the status to "paid" or "settled," which lenders view more favorably, but the entry itself does not vanish. Some newer scoring models (such as FICO 9 and VantageScore 4.0) ignore paid collections entirely, which can help if a lender uses those versions. However, many lenders still use older models. If you believe a collection entry is inaccurate, you have the right to dispute it — our credit report dispute guide explains how.
Myth
You only have one credit score, and that's the number every lender sees.
Fact
There are many credit scoring models, and lenders may use different versions — meaning the score you see may not match what a specific lender pulls.
FICO alone has dozens of scoring versions, including industry-specific models for auto lending and credit cards. VantageScore is a separate model used by many lenders and consumer-facing services. The score you see through a free monitoring app may be a VantageScore or an older FICO version, while your mortgage lender might use FICO 2, 4, or 5 — models that can produce different numbers from the same underlying data. This is not cause for alarm, but it explains why the score you monitor and the score a lender references may differ by 20 to 50 points or more.
Behaviors That Follow From Bad Information
Myths are not just harmless misunderstandings — they drive real decisions. Someone who believes carrying a balance builds credit will pay unnecessary interest every month without any scoring benefit. Someone who closes every card they pay off may watch their score drop before a major loan application. Someone who avoids checking their own report for fear of damage misses the chance to catch errors that could be costing them points right now.
1 in 5
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 bureau reports.
~30%
Of FICO score based on amounts owed
According to FICO's published scoring breakdown, amounts owed — which includes credit utilization — accounts for approximately 30% of a standard FICO score.
35%
Of FICO score based on payment history
Payment history is the single largest factor in a FICO score, underscoring why on-time payments matter more than balance-carrying behavior.
The good news: most of these habits can be corrected without professional help. If you suspect errors on your report, our guide on disputing a credit report error walks through the formal process step by step. And if you're starting fresh rather than correcting course, Building Credit When You're Starting from Zero outlines low-risk approaches that actually work.
Don't Let Myths Drive Loan Decisions
Acting on credit misinformation before a major loan application — such as a mortgage or auto loan — can result in a lower score at exactly the wrong moment. If you're planning to borrow in the next six to twelve months, avoid opening new accounts, closing existing ones, or making large balance moves without understanding the potential scoring impact first. When in doubt, consult a licensed financial professional or a HUD-approved housing counselor before making changes.
