Quick Answer
Several widespread credit score myths are causing real financial harm in 2026. Carrying a credit card balance does not boost your score — it only adds interest costs. Checking your own credit never lowers your score. And closing old cards can actually hurt you by reducing your available credit. At least 4 in 10 Americans hold at least one damaging misconception about how credit scoring works, according to recent consumer research.
Credit score myths are not harmless misunderstandings — they translate directly into higher interest rates, denied loan applications, and unnecessary debt. According to the Consumer Financial Protection Bureau’s credit education resources, even minor scoring errors or behavioral mistakes can shift a borrower’s rate tier by dozens of basis points, costing thousands over the life of a loan.
In May 2026, with interest rates still elevated and lenders applying stricter underwriting standards, acting on bad credit information carries a steeper price than ever before.
Does Carrying a Credit Card Balance Help Your Credit Score?
No — carrying a balance does not improve your credit score, and it actively costs you money in interest. This is one of the most expensive credit score myths still circulating in 2026.
The myth likely originated from a misreading of credit utilization. Your FICO Score — used by 90% of top lenders according to FICO’s official scoring education page — does reward low utilization, meaning your balance relative to your credit limit matters. But “low” means below 30%, and ideally below 10%. A zero balance is never penalized.
Deliberately maintaining a balance only enriches the card issuer. With the average credit card APR sitting above 20% as of early 2026, paying $500 in unnecessary interest to chase a phantom scoring benefit is a losing trade by any measure. Pay your statement balance in full each month — your score and your wallet will both benefit.
Key Takeaway: Carrying a credit card balance provides zero scoring benefit and costs the average borrower hundreds in avoidable interest annually. According to FICO’s scoring guidance, the optimal utilization rate is below 10% — not artificially inflated by an unpaid balance.
Does Checking Your Own Credit Score Lower It?
Checking your own credit score never lowers it. This myth stops millions of Americans from monitoring their credit — which is exactly the kind of oversight that lets errors and fraud go undetected.
Credit inquiries fall into two categories. A soft inquiry occurs when you check your own score, when a lender pre-screens you, or when an employer reviews your credit. Soft inquiries have no effect on your score. A hard inquiry occurs when you formally apply for new credit, and it can trim your score by a modest 5 points or fewer in most cases, according to Equifax’s consumer education guide on credit inquiries.
How Often Should You Check Your Credit?
Financial experts recommend reviewing your full credit report at least once per year. The three major bureaus — Equifax, Experian, and TransUnion — are required by the Fair Credit Reporting Act (FCRA) to provide one free report annually through AnnualCreditReport.com. As of 2023, all three bureaus extended free weekly access permanently.
If you are working to build or repair your profile, reviewing your report monthly is a smart habit. Our guide on credit building mistakes that are hurting your score covers additional monitoring habits worth adopting.
Key Takeaway: Checking your own credit is a soft inquiry and has zero impact on your score. Under the FCRA, you can access your full reports from all 3 bureaus for free at AnnualCreditReport.com — ignoring this leaves errors and fraud undetected.
Does Closing Old Credit Cards Improve Your Score?
Closing old credit cards typically hurts your score rather than helping it. This is one of the most counterintuitive credit score myths, because it seems logical to “clean up” unused accounts.
Two FICO scoring factors are directly damaged when you close a card. First, your credit utilization ratio increases because your total available credit shrinks while your balances stay the same. Second, your average age of accounts — which makes up roughly 15% of your FICO Score — can decline if the closed card was one of your older accounts.
| Credit Score Myth | What People Believe | What Actually Happens |
|---|---|---|
| Carrying a Balance | Boosts score by showing activity | No score benefit; adds 20%+ APR interest cost |
| Checking Your Own Score | Lowers score like a hard inquiry | Soft inquiry — zero score impact |
| Closing Old Cards | Cleans up your credit profile | Raises utilization ratio; can reduce account age |
| Income Affects Score | Higher income = higher score | Income is never a scoring factor in FICO or VantageScore |
| Co-signing Has No Risk | Only the primary borrower is affected | Full debt appears on co-signer’s credit report |
The better strategy for cards you no longer use: keep them open with a small recurring charge — such as a streaming subscription — and pay it in full monthly. This preserves your available credit and account history simultaneously. If you are exploring how to leverage existing credit relationships, see our breakdown of secured cards vs credit builder loans for context on which tools actually build scores efficiently.
“Consumers consistently underestimate how much account age and utilization interact. Closing a card in the name of simplicity can undo years of positive credit history in a single reporting cycle.”
Key Takeaway: Closing a credit card reduces your total available credit and can lower your average account age, which covers 15% of your FICO Score. Unless a card carries a high annual fee, keeping it open with minimal use is the CFPB-recommended approach.
Do Income and Co-signing Affect Your Credit Score?
Your income has no direct effect on your credit score, and co-signing a loan is never a risk-free favor — both are costly credit score myths that catch people off guard.
FICO and VantageScore, the two dominant scoring models in the United States, do not include income, employment status, or net worth as scoring variables. Lenders may consider income separately during underwriting for debt-to-income calculations, but that number never touches your three-digit score. Believing otherwise leads borrowers to neglect the factors that actually matter: payment history (35% of a FICO Score), amounts owed (30%), and length of credit history (15%).
The Real Risk of Co-signing
When you co-sign a loan, the full debt obligation appears on your credit report as if it were your own. If the primary borrower misses a payment, that delinquency hits your report equally — and you have limited recourse. According to Federal Trade Commission consumer finance guidance, co-signers are just as legally responsible as the primary borrower. Before co-signing, read our analysis of whether a co-signer arrangement is the right credit strategy for your situation.
For borrowers navigating thin credit files or non-traditional income, understanding what data actually feeds the scoring models is essential. Our guide on thin credit files vs no credit files clarifies the structural difference and what it means for loan eligibility.
Key Takeaway: Income is never a FICO or VantageScore variable, and co-signing places 100% of the loan liability on your credit report. The FTC confirms co-signers bear equal legal and credit risk — treat the decision as taking out the loan yourself.
Can You Dispute Your Way to a Perfect Score?
Disputing errors is a legitimate right — but it cannot remove accurate negative information, no matter how many disputes you file. This myth fuels a predatory credit repair industry that charges fees for services consumers can do themselves for free.
Under the Fair Credit Reporting Act, both the credit bureau and the data furnisher (typically the lender) must investigate any disputed item within 30 days. If the information is verified as accurate, it stays on your report. Accurate late payments, charge-offs, and collections can remain for up to 7 years; Chapter 7 bankruptcies can remain for 10 years, per CFPB guidelines on negative credit reporting timelines.
What disputes can accomplish is significant: removing inaccurate accounts, correcting wrong balances, and eliminating identity fraud entries. The CFPB found that 1 in 5 consumers had an error on at least one credit report. Fixing a verified error can produce a meaningful, immediate score improvement. If you have experienced lender misconduct that contributed to negative reporting, understanding how to file a CFPB complaint correctly can accelerate resolution.
Key Takeaway: Disputing errors is free and can be impactful — 1 in 5 consumers has at least one reportable credit error, per the CFPB. But accurate negatives stay for up to 7 years; no dispute process, paid or free, can legally remove verified accurate information.
Frequently Asked Questions
Does paying off a collection account remove it from my credit report?
No — paying off a collection account does not automatically remove it from your report. The account status updates to “paid,” which may help with newer scoring models like FICO 9 and VantageScore 4.0, but the collection entry can remain for up to 7 years from the original delinquency date. Negotiating a “pay-for-delete” agreement in writing before paying is one option, though bureaus are not required to honor them.
Will getting married merge my credit score with my spouse’s?
No — credit scores are always individual. Marriage does not combine credit reports or scores. Joint accounts you open together will appear on both reports, and both partners’ payment behavior on those accounts will affect each score independently.
Does being denied for credit hurt your score?
A denial itself has no impact on your credit score. The hard inquiry from the application may reduce your score by up to 5 points temporarily, but the lender’s decision to decline you is not reported to the bureaus and carries no direct scoring consequence.
How long does it take to rebuild a bad credit score?
Recovery timelines depend on the severity of the negative item. A single missed payment can take 12–18 months of consistent on-time payments to substantially offset. A bankruptcy or foreclosure may take 3–7 years to stop dragging your score down significantly. Consistent positive behavior — low utilization, on-time payments, no new derogatory marks — is the only reliable path.
Does rent payment affect your credit score?
Rent payments do not automatically appear on credit reports. However, using a rent reporting service — or requesting your landlord use one — can add positive payment history to your file. For a full breakdown of how this works, see our guide on rent reporting services and the credit boost most renters are ignoring.
Can I build good credit without a credit card?
Yes — credit builder loans, secured loans, and rent or utility reporting can all generate positive credit history without a traditional credit card. A credit builder loan from a credit union or Community Development Financial Institution (CDFI) is particularly effective for those starting from zero. Our guide on how to start building credit from absolute zero covers each option in detail.
