Your credit score is a three-digit number (usually 300–850) that lenders use to predict how likely you are to repay borrowed money. A surprising amount of what people "know" about it is wrong — and here the wrong belief isn't harmless. Believing a myth can cost you real money in interest, a denied application, or a needlessly lower score. Below are nine of the most common credit score myths, each paired with what actually happens, and what actually moves the number.

What actually goes into your credit score?

Just five things, and two of them dominate. A FICO score is built from payment history (35%), amounts owed (30%, mostly your credit utilization), length of credit history (15%), new credit (10%), and credit mix (10%). Notice what's not on that list: your income, your age, your savings, and where you live. Keep this breakdown in mind — most myths fall apart the moment you check them against it.

Typical FICO-style weighting — paying on time is a third of the whole game.

Now, the myths.

The 9 myths, debunked

Here's the fast version before the detail:

The myth The reality
Checking your own score lowers it It's a soft inquiry — zero effect
You must carry a balance to build credit Paying in full builds it just as well, minus the interest
Closing a card helps your score It can raise utilization and hurt
Your income is part of your score Income isn't in the formula at all
Paying a collection erases it It can stay on your report up to 7 years

1. Myth: Checking your own credit score lowers it

Checking your own credit is a "soft inquiry," and soft inquiries never affect your score. Only a "hard inquiry" — when a lender pulls your file because you applied for new credit — can ding it, and only slightly. You're entitled to check your reports for free, and since the pandemic the bureaus have offered weekly free reports at AnnualCreditReport.com. Monitoring your own credit is one of the safest, smartest habits there is.

2. Myth: You have to carry a balance to build credit

False — and it's an expensive myth. Your card issuer reports your on-time payment whether you pay the statement in full or leave a balance, so paying in full builds credit just as well. Carrying a balance simply hands the bank interest — about 21% on the average card — for no scoring benefit. Pay in full, every month, and you get the credit-building and keep the interest. (If you want to see what a carried balance really costs, our guide on how credit card interest works does the math.)

3. Myth: Closing a credit card helps your score

Often the opposite. Closing a card removes its credit limit from your total available credit, which can spike your utilization ratio overnight — and utilization is 30% of your score. Over time it can also shorten your average account age. Unless a card charges an annual fee you no longer want to pay, keeping old cards open and lightly used usually helps more than closing them. We cover the exceptions in does closing a credit card hurt your score.

Utilization is your balance ÷ your limit. Closing a card shrinks the limit, which can push this ratio up even if you owe the same amount.

4. Myth: Your income is part of your credit score

Income isn't in your credit score at all. The score is built only from how you've handled credit — the five factors above. A high earner who misses payments can score below a modest earner who always pays on time. Lenders do ask your income on applications to judge whether you can afford a new loan, but that number never enters the score itself.

5. Myth: You only have one credit score

You have many. There are multiple FICO versions plus VantageScore, and each of the three bureaus — Equifax, Experian, and TransUnion — may hold slightly different data. So your number varies by model and by source. The free score in your banking app can differ from the one a mortgage lender pulls. Don't panic over small gaps between them; watch the trend, not the exact digit.

6. Myth: Paying off a collection or late payment erases it immediately

Paying helps, but it doesn't wipe the slate clean overnight. Most negative marks — late payments, collections, charge-offs — can legally stay on your report for up to seven years, even after you pay. The upside: newer scoring models weigh paid collections less than unpaid ones, and paying stops the collector calls and the growing balance. Just don't expect the history itself to vanish the day you pay.

7. Myth: A single hard inquiry will tank your score

One hard inquiry typically costs only a few points and fades within about a year. And the scoring models are built for comparison shopping: when you rate-shop for a mortgage, auto loan, or student loan, multiple inquiries of the same type inside a short window (often 14–45 days) are bundled and counted as one. The real risk is applying for several unrelated new accounts in a short span, which can signal distress.

8. Myth: You need to be in debt to have good credit

You need to use credit responsibly, which is not the same as owing money. A card you pay in full each month still reports a steady history of on-time payments and low utilization — the two biggest factors — without you ever carrying debt or paying a cent of interest. "Using credit" and "being in debt" are different things.

9. Myth: Your age, salary, or address affect your score

None of those are in the formula. Federal law (the Equal Credit Opportunity Act) keeps factors like age, race, marital status, religion, and national origin out of credit scoring, and your salary and home address aren't scored either. Only your credit behavior counts — which is good news, because behavior is the one thing you control.

Penny's tip: Want the fastest legitimate score bump? Lower your credit utilization. Pay balances down before the statement closes, or ask for a credit-limit increase you don't use — utilization updates every statement cycle, so this can move your score in a month, faster than almost anything else.

The mistakes these myths cause

  • Closing your oldest card to "tidy up," then watching utilization jump and your average account age fall.
  • Carrying a balance on purpose to build credit — paying interest for a benefit you'd get for free by paying in full.
  • Refusing to check your own report out of fear, and missing errors or fraud you had every right to catch.
  • Panicking over one inquiry while ignoring utilization, which matters far more.
  • Paying a "credit repair" company to remove accurate negative marks — something no one can legally do for you.
Heads up: Be skeptical of any company that promises to erase accurate negative information for a fee. Under the Credit Repair Organizations Act, credit-repair firms can't charge you before delivering results, and they can't do anything you can't do yourself for free. Legitimate negative marks generally have to age off on their own timeline.

Who should focus elsewhere (the edge cases)

If you have a thin file or no credit history yet, these myths matter less than simply getting started — opening a starter or secured card and paying it on time. Our guides on how to build credit from scratch and building credit in college are the better starting point.

And if you're currently behind on payments or in hardship, don't spend energy optimizing utilization or account age. Payment history is 35% of your score — the single biggest lever — so catching up and staying current does more for you than any other move on this page. Run the numbers on a realistic payoff with the debt payoff calculator, then focus there first.

Quick answers

Does checking your credit score lower it? No. Checking your own credit is a soft inquiry, which has zero effect on your score, and you can do it as often as you like. Only hard inquiries — when a lender pulls your file for a new application — can lower it, and only by a few points that recover within about a year.

Do I need to carry a balance to build credit? No. Paying your statement in full every month builds credit just as effectively as carrying a balance, because the issuer reports your on-time payment either way. Carrying a balance only adds interest — around 21% on the average card — with no scoring benefit in return.

Does closing a credit card help or hurt my score? It usually hurts, at least short-term. Closing a card removes its limit from your available credit, which can raise your utilization ratio (30% of your score), and can eventually lower your average account age. Keep no-fee cards open and lightly used unless you have a specific reason to close.

Does my income affect my credit score? No. Income isn't one of the five scoring factors and never enters your credit score. Lenders ask your income on applications to judge affordability for a new loan, but that figure doesn't change the score itself.

How long do late payments and collections stay on my report? Most negative marks can remain for up to seven years, even after you pay them off. Paying still helps — it stops collection activity and newer models weigh paid collections less — but it doesn't remove the history immediately.
