11 Things Everyone Gets Wrong About Credit (And 8 Scams That Target You)

A coworker tells you to keep a small card balance "to show activity." A viral video swears by a two-payment "hack." An ad promises a higher score in 72 hours if you pay first. Which are true, and which will cost you money?

A credit tip that promises fast, secret or certain results is usually a myth or a scam; the real steps are slower, simpler and free to take yourself.

What would three bad tips cost?

Example: Marcus wants to buy a home in about a year. A coworker tells him to carry a $300 balance every month "to show activity" (Myths 1 and 11) and never to check his score so he won't "ding it" (Myth 2). A social media ad offers "a guaranteed higher score in 72 hours" for $400 upfront (Scam 5).

• Interest: $300 × 22.36% = about $67 a year, at the August 2026 average rate on bank credit card accounts charged interest (Federal Reserve, preliminary). New purchases also cost interest from day one: a carried balance ends his grace period.
• The ad: $400 handed to a scam.
• Total: at least $467 ($67 + $400), plus a year of not knowing his score.

Instead, he pays each statement in full by the due date, checks his score free monthly, and disputes one genuine error himself. His cost: $0.

What are the 11 things people get wrong about credit?

These myths last because they sound careful.

Myth 1: "You need to carry a balance to build credit"

The CFPB says you don't need a balance or any debt for a good score. Paying in full each month "helps get you the best scores." Why the truth is better: with a grace period and no carried balance, paying the full statement balance by the due date means no interest on new purchases.

Myth 2: "Checking your own score lowers it"

Checking your own score or report is a soft inquiry and doesn't affect your FICO Scores. A hard inquiry, like a card or mortgage application, may. Why the truth is better: check as often as you like. The CFPB says many major card companies show customers a free score monthly.

Myth 3: "Closing old or unused cards helps your score"

Closing a card can raise your utilization: its limit leaves your total. Closed in good standing, it stays on your report and keeps counting for 10 years, so you lose its age later. Why the truth is better: for a no-fee card, the easy move wins: keep it open with one small bill paid in full.

Myth 4: "Keeping utilization under 30% is good"

30% is a ceiling, not a goal. Experian calls it the point where utilization "starts to have a more pronounced negative effect." In its third-quarter 2024 data, people with FICO scores of 800 to 850 averaged 7.1% utilization. Scores can also weigh the card with your highest utilization. Why the truth is better: keeping balances under 10% on each card and overall costs nothing.

Myth 5: "The 15/3 payment hack boosts your score"

The viral rule: pay 15 days and again 3 days before your due date. Issuers generally report once a month, around the statement closing date: one status and one payment amount, however many payments you make. Bills are generally due 21 to 25 days later, so both payments usually come after the balance was reported. Why the truth is better: one move lowers the reported balance: paying down before the statement closes.

Myth 6: "A higher income raises your credit score"

Income isn't in the formula: FICO Scores don't consider your salary, occupation, title or employer. Lenders may weigh income in deciding how much to lend you. Why the truth is better: you don't need a raise. In FICO's published weights, the biggest factors are payment history (35%) and amounts owed (30%). FICO says the importance of these categories may vary from one person to another.

Myth 7: "Paying off a collection instantly fixes your score"

It depends on the score. FICO Scores 9, 10 and 10T and VantageScore 3.0 and 4.0 ignore paid collections, but FICO Score 8, the most widely used version, still counts paid or unpaid collections of $100 or more. Paid or not, a collection can stay on your report for up to 7 years, counted from 180 days after the missed payment that led to it. Medical collections differ: the three bureaus took paid ones off, don't report ones that started under $500, and wait a year before adding unpaid ones. Why the truth is better: you won't count on a jump that may not come. Before paying, get the collector's promises in writing. You can ask it to take the paid account off your reports (a "pay for delete" or goodwill request), but it doesn't have to agree.

Myth 8: "Paying off an installment loan early always helps"

Paying off a loan can cause a slight dip. An open loan with a small balance may help more than a closed one, and if it was your only installment loan, your credit mix can shrink. Experian says the dip is usually temporary if you handle other accounts responsibly, and a loan paid as agreed can stay on your report up to 10 years. Why the truth is better: decide by interest and your budget, not your score.

Myth 9: "More credit cards means a lower score"

Not by itself. Cards you use lightly add to your total limit, which can lower your utilization. The risk is in applying: each application can add a hard inquiry, and FICO says opening several accounts quickly represents greater risk. Why the truth is better: keep balances low and space out your applications.

Myth 10: "You need an 850 to be in good shape"

FICO says creditors "rarely, if ever" require an 850 and might give their best offers to anyone with a score "in the upper 700s and higher" who meets their other criteria. Why the truth is better: there's no need to chase a perfect score.

Myth 11: "You must carry a balance to keep a card active"

Activity means using the card, not paying interest: a small purchase paid in full counts. Use does matter: FICO considers how long it's been since you used certain accounts, and an issuer may close an unused card or lower its limit. Why the truth is better: one small recurring bill on autopay, paid in full, keeps the card in use at $0 in interest.

Which 8 credit scams should you walk away from?

These aren't bad advice; they're traps. Several are federal crimes that make you the lawbreaker. Each shows at least one warning sign: a fast, secret or guaranteed promise; money demanded before any work is done; or a push to use a number that isn't yours or to lie to a bureau or lender. If a 72-hour "fix" sounds good, slow down.

Scam 1: CPNs ("credit privacy numbers")

Sold as a legal Social Security number substitute for a "fresh start." Why it's a scam: federal prosecutors call CPNs "actually stolen Social Security Numbers," and in a 2018 case, the CPNs an Oklahoma man used belonged to children born in 2006 and 2008. The FTC says applying for credit with a number that isn't yours won't work and could bring fines or prison. What it does to you: a federal crime with your name on it. That man got 18 months in prison.

Scam 2: Filing a false identity-theft report

Some online influencers tell people to report their own debts as identity theft, so the bureaus block them. Why it's a scam: on January 5, 2026, the FTC warned that a false report is "a crime that could get you a fine, imprisonment, or both." What it does to you: criminal exposure, and the debt can come back: a bureau may refuse or undo a block based on a material misrepresentation.

Scam 3: Mass-disputing accurate items to "force deletion"

Flooding the bureaus with template disputes, hoping accurate negatives drop off. Why it's a scam: the FTC says "no one promising to repair your credit can legally remove information if it's both accurate and current." A bureau doesn't have to investigate a dispute it reasonably finds frivolous, which the CFPB says can happen with multiple or formulaic requests. What it does to you: wasted months, and accurate items that drop off during a check return once verified.

Scam 4: Buying authorized-user tradelines from strangers

Paying to be added to a stranger's old card. Why it's a scam: the history isn't yours. Under Fannie Mae's rules for mortgages underwritten by hand, a lender can't count such an account unless you show you alone paid it for at least 12 months. What it does to you: money gone, no lasting benefit: once you're removed, the account leaves your report. And knowingly lying on a loan application to a bank or mortgage lender is a federal crime.

Scam 5: "Guaranteed new score in 72 hours"

Services that promise a specific score by a deadline. Why it's a scam: the CFPB says there are no shortcuts to a strong credit history or high scores. Under the Credit Repair Organizations Act (CROA), a credit repair company can't lie about what it can do or charge you before it helps, and it owes you a written contract with three business days to cancel. What it does to you: you pay for nothing and hand a stranger your personal data.

Scam 6: The "infinite money glitch"

Viral videos claim a bank "glitch" pays out free money. Why it's a scam: you write a check for more than you have, deposit it in another of your accounts and withdraw the money before it bounces. On August 11, 2025, the FTC called that bank fraud. What it does to you: you can be "on the hook for paying back all the money," "kicked out of your bank" and in "serious legal trouble for bank fraud."

Scam 7: "3 magic phrases that erase your debt"

Books and videos sell secret wording that supposedly makes the bureaus drop a debt. Why it's a scam: there are no magic phrases. For a real error, write to the bureau and the company that reported it, say what's wrong and why, attach copies of your proof, and follow up. What it does to you: you pay for folklore and skip the free method for real errors.

Scam 8: The "609 letter"

Marketed as a special letter under Section 609 of the Fair Credit Reporting Act that makes the bureaus drop any negative item. Why it's a scam: Section 609 is a disclosure right: on request, a bureau must show you all the information in your file, not take accurate items off it. What it does to you: you pay for a template that does less than a free, specific dispute.

What can I do today?

• If someone wants money to "fix" your credit, or offers a CPN or a "609 letter": don't pay; report it at ReportFraud.ftc.gov.
• If you have a credit card: open its app and write down the statement closing date (the balance then is usually the one reported) and the payment due date (paying the full statement balance by then usually avoids interest).
• Otherwise: send this list to someone paying for a credit "fix" or quoting a viral hack.

Can you spot the illegal offer?

An ad promises "a guaranteed higher score in 72 hours" and asks for $400 before the company starts. What should you do?

• A. Pay; the guarantee protects you
• B. Walk away: charging before the work is done is illegal, and no credit repair company can legally remove accurate, current information ✅
• C. Pay half now and the rest after your score goes up

Why: A credit repair company can't legally take any money before the work is fully done, and the FTC says such companies can't legally remove accurate, current information, so splitting the payment doesn't make the offer safe.
