Widely Believed Credit Score Myths That Can Cost You
Photo credit: QuickInsights.net
From "checking your own score hurts it" to "carrying a balance helps," common credit myths abound. Here's what the evidence actually shows.
Key Takeaways
- Checking your own credit score is a soft inquiry and never lowers your score.
- Carrying a credit card balance does not help your credit score — it only costs you interest.
- Closing old accounts can actually hurt your score by reducing available credit and shortening history.
- Multiple hard inquiries for the same type of loan within a short window are often counted as one.
- A score can be built without carrying debt — paid-in-full balances still demonstrate responsible use.
Why Credit Myths Are So Costly
Credit scores influence loan approvals, interest rates, rental applications, and sometimes even job offers. Getting the facts wrong isn't just an academic error — it can translate into paying thousands more over a lifetime. Many of the most widespread credit beliefs are simply inaccurate, and they persist because they sound plausible. Understanding how credit actually works is one of the most practical things you can do for your finances.
For a plain-language foundation on how scores are calculated, see Credit Scores Explained: What the Number Actually Means. Below, we address the myths that cause the most damage.
Myth
Checking your own credit score will lower it.
Fact
Checking your own score is a "soft inquiry" and has no effect on your credit score whatsoever.
Credit inquiries come in two types: soft and hard. A soft inquiry — which includes checking your own score, employer background checks, and pre-approval screenings — never affects your score. A hard inquiry occurs when a lender pulls your report because you've applied for credit, and it can cause a small, temporary dip. Avoiding your own credit report out of fear is counterproductive: reviewing it regularly is one of the best ways to catch errors. See how to dispute errors on your credit report if you find something inaccurate.
Myth
Carrying a balance on your credit card helps build your credit score.
Fact
Paying your balance in full each month is better for your score — and saves you money on interest.
This myth may stem from a vague idea that lenders want to see "activity." In reality, scoring models reward low utilization and on-time payments, not balances carried month to month. Carrying a balance doesn't signal responsibility — it signals that you owe money, and it generates interest charges that compound quickly. The Real Cost of Carrying a Credit Card Balance illustrates just how fast those charges add up. Pay in full when you can.
Myth
You need to have debt to have a good credit score.
Fact
You can build and maintain a strong credit score by using credit responsibly — without carrying debt.
Using a credit card for regular purchases and paying the full balance before the due date demonstrates responsible credit use. The card issuer reports your activity to the credit bureaus regardless of whether you carry a balance. Over time, consistent on-time payments and low utilization build a solid score. Debt — particularly high-interest credit card debt — is not required and is generally something to minimize.

Myth
Shopping around for loans always hurts your credit score significantly.
Fact
Rate shopping for mortgages, auto loans, and student loans within a focused window is typically treated as a single inquiry by scoring models.
FICO and other scoring models recognize that consumers comparing rates for the same type of loan are being financially responsible, not recklessly seeking credit. Multiple hard inquiries for the same loan type made within a short period — often 14 to 45 days depending on the scoring version — are generally grouped together and counted as one inquiry. The impact is small and temporary in any case. This misconception leads some borrowers to accept the first rate they're offered, which can cost far more over the loan's life. For the specific connection between your score and what lenders charge, why your credit score affects auto loan rates so significantly is worth reading.
Myth
Closing a credit card you don't use will help your score.
Fact
Closing an account typically reduces your available credit and can shorten your credit history — both of which may lower your score.
When you close a card, the credit limit associated with it disappears. If you still carry balances on other cards, your overall utilization ratio rises, which can drag down your score. Additionally, older accounts contribute to the average age of your credit history, a factor in most scoring models. A card you rarely use but have had for years may be worth keeping open, especially if it has no annual fee.

The Broader Picture: Habits and Decisions That Matter
Correcting these myths is a starting point, not the finish line. Credit is shaped by consistent behaviors over time. Payment history is the single largest factor in most scoring models, accounting for roughly 35% of a FICO score. Utilization — how much of your available credit you're using — is the second biggest factor. Everything else, including account age and credit mix, matters but carries less weight.
35%
Payment history weight in FICO score
According to FICO, payment history is the single largest factor in calculating a standard FICO credit score.
30%
Credit utilization weight in FICO score
Amounts owed — including how much of your available credit you're using — makes up about 30% of a FICO score, making it the second most influential factor.

Consumers with a credit report error
A study by the Federal Trade Commission found that approximately one in five consumers had an error on at least one of their three major credit reports.
Some choices that seem harmless can quietly do real damage. Closing an old card, for example, reduces both your available credit and the average age of your accounts. For a closer look at decisions like this, see Credit Decisions That Seem Harmless but Aren't.
