Credit scores affect almost every aspect of your financial life — from mortgage rates to insurance premiums to job applications. Yet misinformation about how credit scores work is everywhere, leading people to make costly mistakes or worry about things that don’t actually matter.

We’re setting the record straight on 15 of the most persistent credit score myths, explaining what’s actually true and how to focus your energy on what genuinely impacts your score. Check out our authorized user guide for more details.

Understanding How Credit Scores Work

Before we debunk the myths, here’s a quick refresher on what actually determines your credit score. FICO scores (used by 90% of lenders) weigh five factors:

Factor	Weight	What It Measures
Payment History	35%	On-time payments vs. late/missed payments
Credit Utilization	30%	How much of your available credit you’re using
Length of Credit History	15%	Age of your oldest account, average age of all accounts
Credit Mix	10%	Variety of account types (cards, loans, mortgage)
New Credit	10%	Recent applications and new accounts

For a deep dive into the scoring model, read our guide on how credit scores actually work.

The 15 Myths

Myth #1: Checking Your Own Credit Score Lowers It

FACT: Checking your own credit score is a “soft inquiry” and has absolutely zero impact on your score. You can check it daily without any effect. What does impact your score is a “hard inquiry” — when a lender pulls your credit during an application. Even then, the impact is small (typically 5–10 points) and temporary.

We encourage regular credit monitoring. See our guide to the best free credit monitoring services for easy ways to stay informed.

Myth #2: You Need to Carry a Balance to Build Credit

FACT: This is one of the most expensive myths in personal finance. You do NOT need to carry a balance or pay interest to build credit. Simply using your card for purchases and paying the statement balance in full each month builds credit perfectly. The credit bureaus see that you’re using credit responsibly — they don’t reward you for paying interest.

Myth #3: Closing Old Credit Cards Helps Your Score

FACT: Closing old credit cards almost always hurts your score. It reduces your total available credit (increasing your credit utilization ratio) and eventually shortens your credit history. If a card has no annual fee, keep it open even if you rarely use it — just make a small purchase every 6 months to prevent the issuer from closing it for inactivity.

Myth #4: Your Income Affects Your Credit Score

FACT: Your income, employment status, job title, and salary are NOT factors in your credit score. Credit scores only measure how you manage debt — not how much you earn. A person making $35,000 can have a higher credit score than someone earning $500,000 if they manage credit better.

Myth #5: All Debt Is Bad for Your Credit

FACT: Having a mix of different credit types (credit cards, auto loan, mortgage, student loans) actually helps your score. The “credit mix” factor accounts for 10% of your FICO score. A mortgage and a car loan, paid on time, demonstrate responsible management of different debt types. The key is making payments on time and not overextending.

Myth #6: Paying Off a Collection Account Removes It from Your Report

FACT: Paying a collection doesn’t remove it from your credit report — it changes the status from “unpaid” to “paid” but the collection account itself stays on your report for 7 years from the date of the original delinquency. However, newer FICO scoring models (FICO 9 and 10) do ignore paid collections, and some lenders view paid collections much more favorably than unpaid ones.

Myth #7: You Only Have One Credit Score

FACT: You have dozens of credit scores. FICO alone has multiple versions (FICO 8, 9, 10, 10T) plus industry-specific scores for auto lending, credit cards, and mortgages. VantageScore is another major scoring model with its own versions. Each bureau (Equifax, Experian, TransUnion) may have different data, so your score can vary across bureaus even using the same model. Learn more about FICO vs. VantageScore.

Myth #8: Married Couples Share a Credit Score

FACT: There’s no such thing as a “joint” credit score. Each person maintains their own individual credit history and scores. Joint accounts (like a shared credit card or mortgage) appear on both spouses’ reports, but your scores are still calculated independently. If your spouse has bad credit, it doesn’t directly affect your score — unless you have joint accounts where they miss payments.

Myth #9: Shopping for a Loan Hurts Your Score Because of Multiple Inquiries

FACT: Credit scoring models recognize rate shopping. Multiple hard inquiries for the same type of loan (mortgage, auto, student) within a 14–45 day window (depending on the scoring model) are counted as a single inquiry. So go ahead and compare rates from multiple lenders — it’s the smart thing to do.

Myth #10: Debit Card Usage Builds Credit

FACT: Debit cards are not reported to credit bureaus and have zero impact on your credit score. Neither do prepaid cards, cash transactions, or checking account activity. Only credit accounts (credit cards, loans, lines of credit) affect your credit score.

Myth #11: A Good Score Means You’ll Be Approved for Any Loan

FACT: Credit score is one factor in lending decisions, but not the only one. Lenders also consider your income, debt-to-income ratio, employment history, down payment amount, and other factors. A high credit score helps significantly, but it doesn’t guarantee approval — especially for large loans like mortgages.

Myth #12: Negative Items Stay on Your Report Forever

FACT: Most negative items (late payments, collections, charge-offs) fall off your credit report after 7 years. Bankruptcies stay for 7–10 years depending on the chapter. Tax liens were removed from credit reports entirely in 2018. After the reporting period expires, these items are automatically removed — you don’t need to do anything.

Myth #13: Using Credit Repair Companies Is the Best Way to Fix Your Credit

FACT: Everything a credit repair company does, you can do yourself for free. Under the Fair Credit Reporting Act, you have the right to dispute inaccurate information directly with the credit bureaus. Many credit repair companies charge hundreds or thousands for services that amount to sending dispute letters — something you can do at CreditMaze. Read our guide on what actually works in credit repair.

Myth #14: Cosigning a Loan Doesn’t Affect Your Credit

FACT: When you cosign a loan, you’re fully responsible for the debt. The loan appears on YOUR credit report, increases your debt-to-income ratio, and any late or missed payments by the primary borrower will damage YOUR credit score. Only cosign if you’re prepared (and able) to make every payment yourself.

Myth #15: You Need to Pay for Your Credit Score

FACT: You can access your credit score for free through numerous sources: your credit card issuer (most provide free FICO scores), Credit Karma (free VantageScore), Experian (free FICO 8), and AnnualCreditReport.com (free credit reports from all three bureaus). There’s no reason to pay for credit monitoring when so many free options exist.

What Actually Matters for Your Credit Score

The Big Two (65% of Your Score)

1. Pay every bill on time, every time. Set up autopay for at least the minimum payment on every account. A single 30-day late payment can drop your score 50–100 points.
2. Keep credit utilization low. Use less than 30% of your available credit — and for the best scores, under 10%. Pay down balances before your statement closes to lower the reported utilization.

The Supporting Cast (35% of Your Score)

• Keep old accounts open to maintain a long credit history
• Maintain a mix of credit types (don’t take on unnecessary debt, but having both installment and revolving credit helps)
• Limit new applications to when you genuinely need credit

The Real Credit Score Factors: Ranked by Impact

Now that we’ve cleared up the myths, here’s a practical ranking of actions by their actual impact on your credit score:

High Impact Actions

• Make every payment on time: Even one 30-day late payment can drop your score 60–110 points and stays on your report for 7 years. Set up autopay immediately.
• Pay down credit card balances: Reducing your utilization from 50% to under 10% can boost your score 50+ points within a single billing cycle.
• Get negative items removed: Successfully disputing inaccurate collections or late payments can result in significant score increases. Always dispute errors.

Moderate Impact Actions

• Become an authorized user: Being added to someone else’s old, low-utilization card can add years of positive history to your report instantly.
• Request credit limit increases: Higher limits reduce your utilization ratio without requiring you to pay down balances. Most issuers allow requests every 6 months.
• Diversify your credit mix: If you only have credit cards, adding a small installment loan (or a credit-builder loan) can help the 10% “credit mix” factor.

Low Impact Actions (But Still Worth Doing)

• Keep old accounts open: Don’t close unused cards — they help your average account age and available credit.
• Space out applications: Limit new credit applications to 1–2 per year unless you’re rate shopping for a specific loan.
• Monitor your reports regularly: Catch errors and fraud early. Use AnnualCreditReport.com for free reports from all three bureaus.

Frequently Asked Questions

What is a good credit score in 2026?

FICO scores range from 300 to 850. Generally: 300–579 is poor, 580–669 is fair, 670–739 is good, 740–799 is very good, and 800–850 is exceptional. Most competitive loan rates require 740+. See our complete guide on what is a good credit score.

How quickly can I improve my credit score?

Some improvements happen fast — paying down a high credit card balance can boost your score within 30 days when the lower balance is reported. Other improvements take time — building a longer credit history or waiting for negative items to age off takes months or years.

Does checking my credit score through my bank affect it?

No. Banks and credit card issuers provide your score through soft inquiries, which have no impact whatsoever. Check it as often as you like.

Will paying off my car loan raise my credit score?

Surprisingly, it might temporarily lower it. Closing an installment account can reduce your credit mix and age of accounts. However, the impact is usually small, and the financial benefit of being debt-free far outweighs a minor score dip.

Can I have a perfect 850 credit score?

Yes — about 1.6% of Americans have a perfect 850 FICO score. However, there’s no practical benefit to 850 vs. 780. Lenders offer the same best rates to anyone above about 760. Chasing perfection is unnecessary.

The most important takeaway from debunking these myths: credit scores reward consistent, boring behavior. Pay on time, keep balances low, and let time work in your favor. There are no shortcuts, secret hacks, or magic fixes — just responsible financial habits practiced consistently over months and years.

Bottom Line

Credit scores are simpler than most people think. Ignore the myths, focus on the fundamentals (pay on time, keep utilization low), and check your score regularly through free services. The rest — credit mix, account age, new inquiries — matters far less than the financial industry sometimes makes it seem. Build good habits, and a strong credit score follows naturally.
