Key Takeaways
- Checking your own credit score does not lower it; only hard inquiries from lenders do.
- Carrying a credit card balance each month does not build credit and costs you interest unnecessarily.
- Closing old credit cards can hurt your score by reducing available credit and shortening credit history.
- Income has no direct effect on your credit score calculation.
- Multiple mortgage or auto loan inquiries within a short window typically count as one inquiry.
Why credit score myths are expensive
Credit scores influence the interest rates families pay on mortgages, car loans, and personal loans. They can affect apartment rental approvals and, in some states, insurance premiums. Mistakes rooted in misunderstanding how scores work translate directly into higher costs over time. The math is not abstract: a difference of 50 to 100 points can change the mortgage rate a borrower qualifies for, adding thousands of dollars to the total cost of a home loan.
Most of the persistent myths fall into two categories: actions people avoid because they wrongly fear score damage, and actions people take because they believe they are building credit when they are not. Correcting both matters.

The myths debunked
The following myth-and-fact pairs cover the most common misunderstandings that affect household budgets. Each one is grounded in how scoring models actually function, based on publicly documented methodology from credit bureaus and the CFPB.
Myth
Checking my 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 fall into two categories. A soft inquiry occurs when you check your own score, when a lender pre-screens you for an offer, or when an employer runs a background check. Soft inquiries do not affect your score. A hard inquiry occurs when you formally apply for credit, such as a mortgage, auto loan, or new credit card. Hard inquiries can lower your score by a few points temporarily. Many free credit monitoring tools, including those offered through banks and credit unions, generate only soft inquiries, so there is no reason to avoid checking your score regularly.
Myth
I need to carry a balance on my credit card to build credit.
Fact
Paying your balance in full each month builds credit history just as effectively, and avoids interest charges entirely.
This myth costs families real money. Credit scoring models reward on-time payments and a low credit utilization ratio (the share of your available credit you are currently using). Carrying a balance from month to month does neither. It simply generates interest charges, which can be substantial depending on your card's annual percentage rate (APR). Paying in full every cycle demonstrates responsible use, keeps your utilization low, and leaves more money in your pocket.
Myth
Closing old credit cards will help my score.
Fact
Closing old accounts typically harms your score by raising your utilization ratio and potentially shortening your credit history.
Your credit utilization ratio compares your total balances to your total available credit across all accounts. When you close a card, that available credit disappears, which can push your utilization ratio higher even if your spending stays the same. Older accounts also contribute to the average age of your credit history, one factor in scoring calculations. If a card has no annual fee, keeping it open and making an occasional small purchase can preserve both the available credit and the account history.
Myth
My income affects my credit score.
Fact
Income is not part of any credit score calculation. Scores measure borrowing and repayment behavior only.
Credit scores are calculated from information in your credit report: payment history, amounts owed, length of credit history, new credit, and credit mix. Income does not appear in credit reports and has no direct effect on your score. Lenders may consider income separately when deciding whether to approve a loan or set a credit limit, but that is a distinct step from the score itself. A high earner with missed payments can have a lower score than a moderate earner with a clean repayment record.
Myth
Shopping around for a mortgage will damage my score because of multiple hard inquiries.
Fact
Mortgage, auto, and student loan inquiries within a short window (typically 14 to 45 days depending on the scoring model) are grouped and counted as a single inquiry.
Credit scoring models recognize that consumers comparison-shop for major loans, and that behavior should not be penalized. FICO scoring models, for example, treat multiple mortgage or auto loan inquiries within a 45-day window as one inquiry. Families who skip rate comparisons because they fear score damage often end up with a higher interest rate, which costs far more over the life of a loan than any minor temporary score dip would. Getting several loan estimates before committing is financially sound and largely safe from a scoring standpoint. This principle connects to broader patterns of overpaying that appear in areas like insurance as well. See why families overpay for insurance for related context.
Credit score errors are common and fixable
The Consumer Financial Protection Bureau (CFPB) has noted that a significant share of consumers find errors on their credit reports. Under the Fair Credit Reporting Act, you can dispute inaccurate information with each of the three major credit bureaus at no cost. Reviewing your reports regularly at AnnualCreditReport.com is one of the most direct ways to protect your score.
What actually moves your score
FICO scores, which most major lenders use, weight five factors. Payment history accounts for roughly 35 percent of the score. Amounts owed (including utilization) accounts for about 30 percent. Length of credit history is around 15 percent. New credit inquiries account for approximately 10 percent, and credit mix (having both installment loans and revolving accounts) makes up the remaining 10 percent.
Paying every bill on time and keeping revolving balances low relative to credit limits are the two actions with the most direct positive effect. Everything else adjusts around those two behaviors.
35%
Weight of payment history in FICO score
According to FICO's publicly documented scoring methodology, payment history is the single largest factor in a standard FICO credit score.
30%
Weight of amounts owed and utilization
FICO's published model weights credit utilization and total balances at approximately 30 percent of the overall score calculation.

Consumers with a credit report error
A Federal Trade Commission study found that approximately one in five consumers had an error on at least one of their three major credit reports.
Misunderstanding how scores work is one part of a broader pattern of preventable household overpaying. Similar misconceptions affect insurance costs, as described in this overview of why families overpay for insurance. The same dynamic appears in health coverage; common deductible myths show how misreading policy terms leads to financial surprises.
