Bad credit advice spreads fast, and some of it quietly raises your interest rates for years. Here are seven persistent credit score myths — and what actually moves your FICO number.
Myth 1: Checking Your Own Score Lowers It
One of the most damaging myths keeps people in the dark about their own credit. Checking your own report or score is a soft inquiry, and soft inquiries never affect your FICO score. You can look at your number daily if you want to, and absolutely nothing happens to it.
What actually costs you points is a hard inquiry — the pull a lender runs when you apply for a card, loan, or mortgage. Each one can shave a few points and stays on your report for two years, though it usually stops affecting your score after twelve months. The fix is to apply only when you genuinely need credit, and to cluster rate-shopping for an auto loan or mortgage into a short window; FICO treats multiple same-type inquiries within roughly 14 to 45 days as a single event.
Because self-checks are free and harmless, there’s no reason to fly blind. AnnualCreditReport.com now gives you free reports from all three bureaus every week, and most card issuers show a monthly FICO or VantageScore at no cost. Reviewing them regularly is how you catch errors and fraud before they turn into denials.
Myth 2: Carrying a Balance Builds Your Credit
This myth is expensive because it feels responsible. Somewhere along the way, people started believing they need to leave a balance on their card each month — and pay interest on it — to prove they can handle debt. That is simply false. Paying your statement in full every month builds credit exactly as well and costs you nothing in interest.
What actually matters is credit utilization, the share of your available credit you’re using, which drives about 30% of your FICO score. The catch is timing: most issuers report your balance on the statement closing date, not the due date. So even if you pay in full every month, a high balance sitting there on the closing date can report as high utilization and dent your score temporarily.
The practical move is to pay the balance down before the statement closes, not just before the due date, so a smaller number gets reported. Aim to keep reported utilization under 30%, and under 10% if you’re preparing for a mortgage or auto loan. Interest is not a fee you pay to build credit; it’s pure lost money that does nothing for your score.
Myth 3: Closing Old Cards Cleans Up Your Report
Tidying up by closing cards you no longer use feels smart, but it often backfires two ways. First, closing a card erases its limit from your total available credit, which pushes your utilization ratio up overnight even if your spending never changed. Second, it can eventually shorten your average age of accounts, and length of credit history is about 15% of your score.
There are real exceptions. If a card charges an annual fee you can’t justify, keeping it isn’t free. Before you cancel, ask the issuer to convert it to a no-fee version of the same card — a “product change” that usually preserves your account age and credit line rather than closing it outright.
The mirror-image myth is that a higher limit is a temptation trap that hurts you. In scoring terms, a bigger limit typically helps, because it lowers utilization. Requesting a credit-limit increase is often done with a soft pull, and even when it isn’t, the math usually works in your favor. To keep old cards from being closed by the issuer for inactivity, put one small recurring charge on each and set it to autopay.
Myth 4: You Have One Score, and Your Salary Is In It
There is no single “your credit score.” FICO alone maintains multiple versions — FICO 8 is common for credit cards, while mortgage lenders often pull older models like FICO 2, 4, and 5, and newer FICO 9 and 10 exist too. Add VantageScore and the fact that each of the three bureaus — Equifax, Experian, and TransUnion — holds slightly different data, and you easily have a dozen numbers at once.
That’s why the score in your banking app can be 30 points off from what a mortgage officer quotes you. Neither is wrong; they’re different models reading different files. When it matters, ask which score and which bureau a lender uses so you’re comparing the same thing.
Just as importantly, your income, savings balance, and job title are not in your credit score at all. Your credit report doesn’t even contain your salary. Lenders do look at income separately — through your application and a debt-to-income calculation — but earning more won’t raise your FICO number, and a fat checking account won’t either. Your age, marital status, and race are likewise excluded by law from the score itself.
Myth 5: Paying Off a Collection Erases It
When an old debt goes to collections, paying it off feels like it should wipe the slate clean. It usually doesn’t. A collection, charge-off, or late payment can stay on your report for about seven years from the original delinquency whether you pay or not, and a paid collection still shows up as a paid collection.
Paying still matters, though, and here’s the nuance the myth misses. Newer scoring models — FICO 9 and 10 and current VantageScore versions — ignore collection accounts once they’re paid, while older models that many lenders still use keep counting them. So settling a collection can help you with some lenders and not others, which is a reason to do it rather than a reason to skip it.
Medical debt gets special treatment worth knowing: paid medical collections are no longer reported, and unpaid medical collections under $500 have been removed from consumer reports. If you’re negotiating, ask the collector in writing whether they’ll delete the entry upon payment, and never assume a verbal promise will stick. Finally, remember that recent negatives hurt far more than aging ones — a two-year-old late payment weighs much less than last month’s, so time genuinely does heal.
