Most bad credit decisions don’t come from ignorance. They come from confidently believing something that just isn’t true. Credit myths get passed around so often — by well-meaning relatives, old blog posts, or a guy on TikTok who read one Reddit thread — that they start to sound like common sense. Some of them cost you real points. A few cost you real money.
Here are eight of the ones we hear most often, what’s actually going on under the hood, and what to do instead.
Myth 1: Carrying a balance helps your score
This is probably the most expensive myth in personal finance, and it refuses to die. The idea is that paying interest somehow “shows the bureaus you can handle credit.” It doesn’t. Scoring models have no idea whether you paid your statement in full or let it ride and rack up interest — they only see the balance that gets reported to the bureau, usually once a month around your statement date.
What actually helps is using your cards regularly and keeping reported balances low relative to your limits, then paying in full so you’re not handing the credit card company free money. If you want a real number to aim for, the general guidance from credit bureaus is to stay under 30% utilization, with the best scores usually sitting in the single digits. Interest paid on a carried balance does nothing for your score — it just pads the issuer’s earnings.
Myth 2: Checking your own score hurts it
This one keeps people from monitoring their credit at all, which is a shame, because that’s exactly the behavior you want to encourage. When you check your own score or report — through your bank’s app, a free credit monitoring tool, or annualcreditreport.com — it’s classified as a soft inquiry. Soft inquiries never affect your score, no matter how often you check.
What actually dings your score is a hard inquiry, which only happens when you apply for new credit and a lender pulls your file with your authorization. Even then, the hit is typically small and fades from your score’s calculation well before it drops off your report entirely.
Myth 3: Closing a card you don’t use is always the responsible move
Marie Kondo-ing your wallet feels productive, but closing a credit card can quietly work against you in two ways. First, it removes that card’s credit limit from your total available credit, which can push your overall utilization ratio up even if your spending hasn’t changed. Second, if it’s one of your older accounts, closing it eventually shortens the average age of your credit file, since closed accounts in good standing only stick around on your report for so long before they age off.
Both matter. Length of credit history and utilization are meaningful pieces of your score, so if a no-annual-fee card isn’t causing any harm sitting in a drawer, there’s often more upside to leaving it open than to closing it.
Myth 4: A hard inquiry will tank your score for years
A single hard inquiry is a minor, short-lived event — usually a small dip, not the double-digit collapse people picture. It stays on your report for around two years, but most scoring models stop factoring it into your score well before that window closes. Rate shopping for something like an auto loan or mortgage within a focused window is typically treated as a single inquiry too, so comparing offers won’t multiply the damage the way people assume.
Where inquiries actually add up is when you apply for several unrelated products — a credit card, a personal loan, a store card — all in a short stretch. That pattern can look like financial distress to a lender, even if each individual inquiry barely moved your score.
Myth 5: Being an authorized user is a shortcut to a great score
Getting added as an authorized user on a family member’s well-managed card can genuinely help, especially if you’re starting from no credit history at all. The account’s history can show up on your report and contribute to your score. But it comes with caveats people skip over. Not every issuer reports authorized user activity to the bureaus, so it’s worth confirming before assuming it’ll help. And the benefit only flows one way — if the primary cardholder misses payments or runs high balances, that shows up on your report too.
It’s also not a substitute for your own credit. Lenders evaluating you for a mortgage or a card in your own name want to see that you’ve managed debt you’re actually responsible for, which an authorized user account can’t fully demonstrate on its own.
Myth 6: You need to carry multiple cards to have a “good” credit mix
Credit mix — the variety of account types you manage, like credit cards versus installment loans — does factor into your score, but it’s one of the smaller pieces of the puzzle. Opening a card, a car loan, and a personal loan you don’t need just to diversify your file is generally not worth the hard inquiries and the temptation to overspend. If you already have a card or two in good standing and pay everything on time, chasing a “perfect” mix has limited upside compared to just keeping utilization low and payments on time.
Myth 7: Paying off a collections account removes it from your report immediately
Paying a collections account is usually the right move, and some issuers will negotiate a “pay for delete” agreement, but there’s no guarantee it disappears the moment you pay. Depending on the debt type and how it’s reported, a paid collection can still show on your report for years, though it typically counts against you less than an unpaid one and its impact fades over time. Newer scoring models also tend to treat paid collections more gently than unpaid ones, so paying is still worth doing — just don’t expect it to erase the history overnight.
Myth 8: Your income affects your credit score
Income doesn’t appear anywhere in a credit score calculation. You can earn six figures and still have a mediocre score if you’re maxing out cards or missing payments, and someone earning far less can have excellent credit by managing what they do have responsibly. Income matters a lot to lenders when they’re deciding whether to approve you and for how much, but it’s a separate conversation from the score itself, which is built entirely from how you’ve handled credit — payment history, utilization, account age, mix, and recent inquiries.
Frequently asked questions
What actually has the biggest impact on my credit score?
Payment history and credit utilization carry the most weight in most scoring models. Paying every bill on time, every time, and keeping your card balances low relative to your limits will move the needle more than almost anything else on this list.
Is it bad to have a $0 balance on all my cards?
Not exactly, but a mix of small, regularly reported balances tends to score slightly better than showing zero usage everywhere, since scoring models want some recent activity to evaluate. The difference is usually minor — don’t go out of your way to carry a balance just to avoid a $0 report.
How often should I check my own credit score?
As often as you like. Since it’s a soft inquiry, there’s no downside to checking monthly or even weekly through a bank app or free monitoring service. Regular checks make it easier to catch errors or fraud early.
Should I close credit cards I no longer use?
Generally, only if the card has an annual fee that isn’t worth paying, or if you genuinely can’t trust yourself not to overspend on it. Otherwise, leaving a no-fee card open with occasional small purchases usually helps more than closing it hurts.
Does applying for a new credit card always hurt my score?
It usually causes a small, temporary dip from the hard inquiry, but that’s typically outweighed over time by the extra available credit and, if you use it well, the positive payment history the new account adds.
Credit scoring formulas vary by bureau and by which scoring model a lender uses, and specific point impacts differ from person to person. This article covers general patterns rather than guaranteed outcomes — when in doubt, check your own credit report for the specifics of your situation and confirm details with your card issuer or a qualified credit counselor.
