Your Credit Score Confusion Is Expensive
Your credit score affects almost every major financial decision in your life — mortgage rates, car loans, credit card approvals, apartment rentals, and even some job applications. A difference of just 50 points can cost you tens of thousands of dollars in extra interest over a lifetime.
Yet most people operate on myths and misconceptions about how credit scores actually work. These misunderstandings lead to bad decisions that damage their scores and cost them real money. Let’s bust the most common credit score myths once and for all.
Myth 1: Checking Your Own Credit Score Lowers It
The Truth: Checking your own credit score is a “soft inquiry” and has absolutely zero impact on your score. You can check it daily if you want — it won’t change a thing.
What does affect your score are “hard inquiries,” which happen when a lender checks your credit because you’ve applied for a loan or credit card. Each hard inquiry typically drops your score by 2-5 points temporarily and falls off your report after two years.
What this myth costs you: People who avoid checking their credit miss errors and fraud that could be dragging their score down. A Federal Trade Commission study found that 1 in 5 consumers has an error on their credit report. If you’re not checking, you can’t catch these mistakes.

Myth 2: You Need to Carry a Balance to Build Credit
The Truth: This is perhaps the most expensive myth in personal finance. You do NOT need to carry a balance and pay interest to build credit. Using your card and paying it off in full every month builds credit just as effectively — and you pay zero interest.
Credit scoring models care about whether you use credit responsibly, not whether you pay interest. Your payment history (paying on time) and credit utilization (how much of your available credit you use) are what matter.
What this myth costs you: If you carry a $3,000 balance on a credit card with 22% APR, you’re paying $660 per year in interest for absolutely no credit score benefit. Over 10 years, that’s $6,600 thrown away.
Action step: Use your credit cards for regular purchases, then pay the full statement balance every month. Autopay is your friend.
Myth 3: Closing Old Credit Cards Helps Your Score
The Truth: Closing old credit cards almost always hurts your score, for two reasons:
It reduces your total available credit, which increases your credit utilization ratio. If you have $10,000 in total credit and use $2,000, your utilization is 20%. Close a card with a $5,000 limit, and that same $2,000 usage becomes 40% utilization — a significant negative.
It can shorten your average account age. Length of credit history accounts for 15% of your FICO score. Older accounts help your score.
What this myth costs you: People who close old cards before applying for a mortgage or car loan inadvertently raise their utilization and lower their score, resulting in higher interest rates.
Action step: Keep old cards open, even if you rarely use them. Put a small recurring charge on them (like a streaming subscription) and set up autopay so they stay active.
Myth 4: Your Income Affects Your Credit Score
The Truth: Your income is not a factor in any credit scoring model. A person earning $30,000 per year can have a higher credit score than someone earning $300,000. Credit scores measure how you manage debt, not how much money you make.
Lenders do consider your income when deciding whether to approve you for credit, but the credit score itself is based entirely on your credit behavior.
Why this myth persists: High-income individuals often have access to more credit and can pay bills more easily, which indirectly helps their scores. But the score calculation itself is income-blind.
Myth 5: Paying Off Collections Immediately Removes Them
The Truth: Paying off a collection account doesn’t automatically remove it from your credit report. The account will still show as a paid collection for up to seven years from the original delinquency date.
However, newer FICO scoring models (FICO 9 and FICO 10) ignore paid collections entirely. And many lenders using older models still view paid collections much more favorably than unpaid ones.
Better strategy: Before paying a collection, negotiate a “pay for delete” agreement where the collection agency agrees to remove the account from your credit report in exchange for payment. Get this agreement in writing before you pay a cent. Not all agencies will agree, but many will — especially for older debts.
Myth 6: You Only Have One Credit Score
The Truth: You have dozens of credit scores. FICO alone has over 50 different scoring models, and VantageScore has several versions as well. Different lenders use different models, and each model may weight factors slightly differently.
Your FICO 8 score (the most commonly used) might be 750 while your VantageScore 3.0 is 730 and your FICO Auto Score (used for car loans) is 760. This is normal.
What this means for you: Don’t obsess over a single number. Focus on the behaviors that improve all scores: pay on time, keep utilization low, maintain a mix of credit types, and avoid unnecessary hard inquiries.
Myth 7: Cosigning Doesn’t Affect Your Credit
The Truth: When you cosign a loan, that debt appears on your credit report as if it were your own. If the primary borrower misses payments, your credit score takes the hit. If they default, you’re legally responsible for the full balance.
What this myth costs you: Countless people have had their credit destroyed by cosigning for someone who couldn’t (or wouldn’t) pay. A single missed payment on a cosigned loan can drop your score by 50-100 points.
Action step: Only cosign if you can genuinely afford to make the payments yourself and are willing to accept the risk. In most cases, the answer should be no.
Myth 8: Debit Cards Build Credit
The Truth: Debit card transactions are not reported to credit bureaus. Using a debit card — no matter how responsibly — does absolutely nothing for your credit score. Credit scores are based on credit usage, and debit cards are not credit.
What this myth costs you: Young adults who use only debit cards thinking they’re building credit arrive at their first mortgage application with a thin credit file and no score history, resulting in higher rates or denial.
Action step: Get a secured credit card if you can’t qualify for a regular one. Use it for small purchases and pay it off monthly. This builds credit history that debit cards never will.
Myth 9: Shopping for Loans Tanks Your Score
The Truth: Credit scoring models recognize that rate shopping for a mortgage, auto loan, or student loan is smart consumer behavior. Multiple inquiries for the same type of loan within a 14-45 day window (depending on the scoring model) are treated as a single inquiry.
What this myth costs you: People who don’t shop around because they’re afraid of multiple inquiries end up accepting the first offer they receive, which is rarely the best rate. The difference between the first offer and the best offer can be tens of thousands of dollars over the life of a loan.
Action step: When shopping for a mortgage or car loan, get quotes from at least 3-5 lenders within a two-week period. The inquiries will be bundled into one, and you’ll likely save thousands.
Myth 10: Bankruptcy Means Your Credit Is Ruined Forever
The Truth: While bankruptcy is serious and stays on your report for 7-10 years, your credit can start recovering immediately. Many people who file bankruptcy see significant score improvements within 1-2 years by using secured credit cards responsibly and making all payments on time.
Ironically, some people have higher credit scores two years after bankruptcy than they did before filing, because their debt-to-income ratio improves dramatically once the discharged debts are cleared.
The Five Things That Actually Matter
Instead of worrying about myths, focus on the five factors that genuinely determine your FICO score:
- Payment history (35%) — Pay every bill on time, every time
- Credit utilization (30%) — Keep usage below 30% of your limit, ideally below 10%
- Length of credit history (15%) — Keep old accounts open
- Credit mix (10%) — Have a healthy mix of credit types (cards, installment loans)
- New credit (10%) — Avoid opening too many accounts in a short period
That’s it. Master these five areas and your credit score will take care of itself. Ignore the myths, follow the math, and watch your score climb.
