Most of what people believe about credit scores is wrong.
Not slightly off — flat-out wrong. And because bad information spreads faster than accurate information in personal finance, millions of Americans are actively doing things they think will help their score while unknowingly sabotaging it. Others are avoiding things they believe will hurt their score — when in reality those actions would help.
Credit scores matter more than most people realize. A difference of 100 points on a FICO score can mean the difference between a 6.5% and a 7.9% mortgage rate. On a $300,000 home loan, that gap costs you over $85,000 in extra interest over 30 years. This isn’t abstract — the myths below have real dollar amounts attached to them.
Let’s clear the record.
Myth #1: Checking Your Own Credit Score Will Lower It
The truth: Checking your own score has zero impact. Zero.
This is probably the most damaging myth in personal finance because it stops people from monitoring one of their most important financial assets. The fear of “hurting” your score by checking it causes people to fly blind — missing errors, missing fraud, and missing opportunities to improve.
Here’s how it actually works: there are two types of credit inquiries. A hard inquiry happens when a lender pulls your credit because you’re applying for new credit — a mortgage, car loan, credit card, or similar. Hard inquiries can temporarily lower your score by a few points because they signal you may be taking on new debt. A soft inquiry is when you — or a service you’ve authorized — checks your credit for informational purposes. Soft inquiries never affect your score at all.
Checking your own score through AnnualCreditReport.com, your bank’s free credit monitoring, or apps like Credit Karma is always a soft inquiry. It cannot hurt you.
The Consumer Financial Protection Bureau recommends checking your full credit report from all three bureaus — Experian, Equifax, and TransUnion — at least once per year. You’re entitled to free weekly reports from AnnualCreditReport.com. Use them.
Myth #2: Carrying a Balance on Your Credit Card Helps Your Score
The truth: Carrying a balance does nothing positive for your score — and costs you money in interest.
This myth is surprisingly widespread, and it appears to have originated from a misunderstanding of how credit utilization works. The logic people use goes something like: “If I carry a small balance, it shows I’m actively using credit, which proves I can handle it responsibly.” That logic is wrong.
Your credit score cares about your credit utilization ratio — the percentage of your available credit that you’re using at any given time. This factor accounts for approximately 30% of your FICO score, making it the second most important element after payment history.
What matters to your score is how much of your available credit you’re using when the statement closes — not whether you paid it off last month. Carrying a balance from month to month doesn’t demonstrate creditworthiness. It just means you’re paying interest, which could mean spending more on the things you buy because you’re also paying interest.
The ideal approach: use your card regularly (which demonstrates active credit usage), then pay the full balance before the due date every single month. This keeps your utilization low, avoids interest charges entirely, and shows exactly the behavior lenders want to see.
For your score specifically, aim to keep your credit utilization below 30% on each individual card and across all cards combined. Ideally, keep it closer to 10% if you want to maximize this component of your score.
Myth #3: Closing Old, Unused Credit Cards Is a Smart Move
The truth: Closing old cards almost always hurts your score — sometimes significantly.
This one feels intuitive. You have a credit card you haven’t used in two years, it’s just sitting there, why not clean house and close it? The problem is that closing it does two damaging things to your credit score simultaneously.
First, it reduces your total available credit, which raises your utilization ratio. If you have $20,000 in total available credit and $4,000 in balances, your utilization is 20%. Close a card with a $5,000 limit and suddenly you have $15,000 available with the same $4,000 balance — now your utilization jumps to 27%. That can move your score meaningfully in the wrong direction.
Second, it can shorten your average credit history length, which accounts for about 15% of your FICO score. Closing a credit card will never improve your credit score — in fact, it’s likely to ding your score, and that’s one reason experts generally don’t recommend it.
The exception: if a card has an annual fee you’re not getting value from, call the issuer first and ask to downgrade to a no-fee version of the same card. That keeps the account open and the credit history intact without costing you money every year.
Myth #4: You Have One Credit Score
The truth: You have dozens of credit scores — potentially hundreds.
When someone says “my credit score is 740,” they’re giving you an incomplete picture. In reality, you have multiple credit scores calculated by different models, using data from different bureaus, weighted differently depending on the type of loan being evaluated.
FICO is a brand, not a specific score, and there are many different scores — there are three credit bureaus and several generations of FICO’s scoring software still in use today. Auto lenders typically use a score specifically weighted for auto loan repayment behavior. Mortgage lenders use a different model. Credit card issuers use yet another. VantageScore, a competing scoring model, calculates scores differently from FICO entirely.
What this means practically: the score you see in your bank’s app may look different from the score a mortgage lender pulls — sometimes by 20–50 points. That’s not an error. It’s the reality of a fragmented credit scoring system.
The practical implication: focus on the behaviors that improve scores across all models — on-time payments, low utilization, long account history, diverse credit mix — rather than obsessing over a single number from a single source.
Myth #5: Paying Off a Loan Always Boosts Your Score
The truth: Paying off certain loans can temporarily lower your score.
This is one of the most counterintuitive facts in credit scoring, and it regularly surprises people who do the right financial thing and then watch their score drop.
Here’s the explanation: FICO rewards credit mix — having experience with different types of credit accounts, including both revolving accounts (credit cards) and installment accounts (mortgages, auto loans, student loans). This factor accounts for about 10% of your score.
Paying off an installment loan such as a car or personal loan may cause a small drop in credit score. One reason for that impact is that paying off an account can lessen your credit mix — or variety in the number and types of open debt accounts listed on your credit reports.
This doesn’t mean you should keep loans open just to protect your score — that’s financially absurd. Pay off your debts. But don’t be alarmed if your score dips slightly after paying off an auto loan or student loan. It’s normal, it’s usually modest, and it will recover as your remaining accounts continue to age and perform well.
Credit cards work differently: paying off a credit card balance in full does help your score by reducing utilization. The temporary dip issue applies specifically to installment loans.
Myth #6: Shopping Around for Loans Will Wreck Your Score
The truth: Rate shopping for mortgages and auto loans is treated as a single inquiry when done within a focused window.
People avoid getting multiple mortgage quotes or comparing auto loan rates because they’re afraid each inquiry will ding their score. This fear is costing them real money — accepting worse loan terms than they could have gotten if they’d shopped around.
For some types of credit, like auto and mortgage loans, when lenders offering the same type of loan request your credit score within a time span ranging from 14 to 45 days, FICO treats those multiple inquiries as a single inquiry. The exact window depends on the FICO version being used, but the principle is consistent: credit bureaus recognize that a responsible consumer shops around for the best rate rather than accepting the first offer.
For credit cards, this rate-shopping protection does not apply in the same way — each application typically counts as its own hard inquiry. But for the two biggest loan types most people take out — mortgages and car loans — get as many quotes as you need within that 14–45 day window. The impact on your score is minimal, and the savings from finding a better rate can be enormous.
Myth #7: A Bad Credit Score Will Follow You Forever
The truth: Credit scores are snapshots, not permanent records — and they respond faster than most people expect.
This myth discourages people who’ve had financial setbacks from even trying to rebuild. The thinking goes: “I missed payments during a rough patch / went through bankruptcy / had a collections account — my credit is ruined for life.” That’s not how the system actually works.
A score is a “snapshot” of your risk at a particular point in time. It changes as new information is added to your bank and credit bureau files. Scores change gradually as you change the way you handle credit. Past credit problems impact your scores less as time passes.
Here’s the actual timeline: most negative items — late payments, collections, charge-offs — remain on your credit report for seven years from the date of the original missed payment. Chapter 7 bankruptcy stays for ten years. But here’s the critical nuance: the impact of those negative marks diminishes steadily over time, especially once you establish positive payment history on top of them.
Someone who went through a financial crisis two years ago and has been building responsibly since can have a meaningfully better score today than someone who had perfect credit three years ago but started missing payments recently. Recency matters. Direction matters. The score responds.
If you’re rebuilding, the fastest levers are: get a secured credit card, use it for small purchases, pay it in full every month, and let time work in your favor.
Myth #8: Your Income and Savings Determine Your Credit Score
The truth: Your credit score has no idea how much money you make or how much you have in the bank.
This surprises people at both ends of the income spectrum. High earners assume their salary must be boosting their score. People with modest incomes assume the score is stacked against them from the start. Both are wrong.
Your income is not found in the credit report. The same goes for the balances in your checking and savings accounts, and other assets such as how much you have sitting in your retirement nest egg.
FICO scores are calculated exclusively from information in your credit report. The five components are: payment history (35%), credit utilization (30%), length of credit history (15%), credit mix (10%), and new inquiries (10%). A person making $40,000 a year who pays every bill on time, carries low balances, and has a long credit history will have a better score than someone making $200,000 who maxes out cards and misses payments occasionally.
This cuts the other way, too: a high income does not protect you from a bad score. It only helps if you’re also doing the behavioral things that actually matter — paying on time, keeping utilization low, and not opening a stack of new accounts all at once.
The One Thing That Actually Matters More Than Everything Else
If you took nothing else from this article, take this: payment history is 35% of your FICO score — the single largest factor by far.
Every other myth, strategy, and optimization discussed above runs a distant second to this simple fact: pay every bill on time, every month, without exception. One missed payment can drop a score by 50–100 points depending on your starting position. A pattern of missed payments is the fastest way to ensure bad terms on every loan you’ll ever take out.
Set up autopay for at least the minimum on every account. Then pay the full balance manually before the due date if you can. That combination — autopay as a backstop, full payment as the goal — protects your score from the most damaging thing that can happen to it while keeping utilization low.
For Veterans: Two Credit Facts Worth Knowing
The SCRA protects your credit during active duty. The Servicemembers Civil Relief Act caps interest rates at 6% on pre-service debt during active duty — which prevents the high interest from creating unpayable balances that turn into missed payments that tank your score. If you’re on active duty, invoke this protection in writing with every lender.
VA loan applications are not treated as multiple hard inquiries. Shopping around for VA mortgage lenders is subject to the same rate-shopping window protection described above. Get multiple VA loan quotes. Compare lenders. The score impact is minimal, and the rate difference between lenders can be meaningful over a 30-year loan.
The Bottom Line
Credit scores are built on a set of rules that are knowable, learnable, and workable. The myths above persist because credit bureaus don’t exactly publish advertising campaigns explaining how their models work — and misinformation fills that vacuum.
What actually moves your score in the right direction is straightforward: pay on time, keep balances low relative to limits, keep old accounts open, don’t apply for several new accounts at once, and let time do its work. That’s it. No tricks, no secret strategies, no credit repair companies required.
The myths are costing people real money — in higher interest rates, in poor decisions made out of fear, and in missed opportunities to actually improve. Now you know better.
