Key Takeaways
- Checking your own credit score never lowers it — only hard inquiries from lenders can do that.
- Closing old credit card accounts can actually hurt your score by raising your utilisation ratio.
- Carrying a monthly balance on your card does not build credit faster than paying in full.
- Income is not a factor in any standard credit score calculation.
- Multiple loan-rate inquiries within a short window are typically counted as a single hard pull.
Why Credit Score Myths Spread — and Why They're Costly
Credit scores shape access to mortgages, car loans, apartment leases, and sometimes even employment background checks. Despite that significance, a surprising amount of everyday credit advice circulates without any factual foundation. These myths typically spread because credit scoring is opaque by design — the full proprietary formulas aren't public — leaving room for plausible-sounding guesses to fill the gap.
The real cost isn't just confusion. Believing inaccurate credit claims can lead to concrete financial harm: avoiding self-monitoring, carrying unnecessary interest-bearing balances, or closing accounts that were quietly supporting your score. Understanding what credit scores actually measure is the essential starting point. Our article Credit Scores Explained: What the Number Actually Measures lays out the fundamentals clearly.
The myth-and-fact pairs below address the most persistently repeated misconceptions, grounded in how the major scoring models — primarily FICO and VantageScore — are publicly known to function.
Myth
Checking your own credit score will lower it.
Fact
Viewing your own score is a 'soft inquiry' and has zero effect on your credit score.
There are two types of credit inquiries: hard and soft. A hard inquiry occurs when a lender pulls your report to make a lending decision — that can temporarily lower your score by a few points. A soft inquiry happens when you check your own score, or when a lender pre-screens you for an offer. Soft inquiries are invisible to other lenders and carry no scoring weight whatsoever.
Avoiding your own score out of fear of damage is counterproductive. Regular self-monitoring is one of the best ways to catch errors early. See our guide on disputing credit report errors if you find something inaccurate.
Myth
Carrying a balance from month to month helps build your credit score.
Fact
Paying your balance in full each month is just as effective for building credit — and saves you interest charges.
This myth may have originated as a misunderstanding of how lenders report activity. What matters to your score is that you use your credit account and pay on time — not that you carry a revolving balance. Carrying a balance means you pay interest, which benefits the card issuer, not your score.
In fact, carrying a high balance relative to your limit can hurt your score by raising your credit utilisation ratio — one of the most influential scoring factors. For a deeper look, see how credit utilisation works and what level is considered healthy.
Myth
Closing old credit cards you no longer use will improve your score.
Fact
Closing old accounts typically lowers your score by reducing available credit and potentially shortening your average account age.
Two scoring factors are directly affected when you close an account: credit utilisation and length of credit history. When you close a card, that card's available credit limit disappears from your total, which can push your utilisation ratio higher — a negative signal. Closed accounts in good standing do remain on your report for up to 10 years, softening the age impact somewhat, but the utilisation effect is immediate.
If a card has an annual fee you can no longer justify, consider whether a product change (switching to a no-fee version with the same issuer) is possible before closing entirely. Understand all five factors behind your credit score before making this decision.
Myth
Your income directly affects your credit score.
Fact
Standard credit scores — FICO and VantageScore — do not include income as a scoring variable.
Credit scores measure your track record of managing borrowed money, not your wealth or earnings. Lenders may ask for income separately when evaluating an application — that's their own underwriting process — but the score itself reflects payment history, amounts owed, account age, credit mix, and new credit inquiries.
This is why someone with a modest income but disciplined repayment habits can hold an excellent score, while a high earner who misses payments regularly may have a poor one. For a thorough breakdown, see what a credit score actually measures.
Myth
Shopping around for a mortgage or auto loan will cause multiple hard inquiries and tank your score.
Fact
Credit scoring models treat multiple inquiries for the same loan type within a short window (typically 14–45 days) as a single inquiry.
The scoring models are designed to encourage comparison shopping. If you apply with several mortgage lenders within a short period, the model recognises you are rate-shopping for one loan — not opening several new lines of credit simultaneously. The exact de-duplication window varies by scoring model (FICO's range is generally 14 to 45 days depending on the version), but the protective logic is consistent across major models.
Avoiding rate comparisons to protect your score is therefore a costly misunderstanding. The small, temporary score dip from a hard inquiry is almost always far less consequential than securing a lower interest rate over a multi-year loan term.
Habits Worth Building Once the Myths Are Cleared Away
With the misconceptions addressed, a clearer picture of healthy credit behaviour emerges. The fundamentals are straightforward: pay every bill on time, keep your balances well below your credit limits, avoid opening several new accounts in a short period, and monitor your own report regularly for errors.
Be Cautious of 'Credit Repair' Promises
Companies that promise to quickly remove accurate negative information from your credit report — for a fee — are not offering something that is legally possible. Accurate, verified negative items remain on your report for a set period under federal law (generally seven years for most derogatory marks). You have the right to dispute genuinely inaccurate information yourself, for free, directly with the credit bureaus.
Credit score improvement is rarely dramatic or fast — most meaningful gains happen over months and years of consistent behaviour. There are no shortcuts that work without risk, and services claiming to rapidly erase accurate negative information from your report are not delivering on a legitimate promise.
