Credit Score Myths That Mislead Everyday Borrowers

Many common beliefs about credit scores are simply wrong. This article separates fact from fiction using publicly established credit reporting principles.
Key Takeaways
- Checking your own credit score does not lower it; only hard inquiries from lenders do.
- Carrying a credit card balance month to month does not build credit and costs you interest.
- Closing old accounts can actually reduce your score by shortening your credit history.
- Income is not a factor in your credit score calculation at all.
- A score of 700 does not guarantee loan approval; lenders apply their own criteria beyond the number.
Why these myths stick around
Credit scores touch nearly every major financial decision a household makes, from renting an apartment to financing a car to qualifying for a mortgage. Yet the information circulating about how scores actually work is often wrong, passed along by well-meaning friends or misread headlines. The consequences are real: families pay more interest, avoid beneficial financial moves, or make choices that quietly drag their scores down over time.
The three major credit bureaus (Equifax, Experian, and TransUnion) report data to scoring models such as FICO and VantageScore. Those models weigh factors including payment history, amounts owed, length of credit history, new credit inquiries, and credit mix. Understanding those inputs directly is the most reliable way to protect your score. This article covers the most consequential myths and what the evidence actually shows.

Myth
Checking your own credit score hurts 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 credit or when a lender pre-screens you without a formal application. A hard inquiry occurs when a lender pulls your report in response to an actual credit application. Only hard inquiries affect your score, and typically only by a few points for a short period. Avoiding your own credit report out of fear of damaging your score means you miss errors that could be costing you far more than a single hard inquiry would.
Myth
You need to carry a balance to build credit.
Fact
Paying your balance in full each month builds credit just as well, while avoiding interest charges entirely.
This myth likely originated as a misunderstanding of how utilization works. Lenders do want to see that you use credit, but they do not care whether you carried a balance into the next billing cycle. What they see is whether you pay on time and what percentage of your available credit you are using. Carrying a balance means paying interest for no scoring benefit. Paying in full each month builds a clean payment history and keeps utilization low, which serves your score better than a revolving balance does.
Myth
Closing a credit card you no longer use will improve your score.
Fact
Closing an account typically lowers your score by reducing available credit and potentially shortening your credit history.
When you close a credit card, two things happen that can hurt your score. First, your total available credit drops, which raises your overall utilization ratio if you carry any balances elsewhere. Second, if the card is one of your older accounts, closing it can reduce the average age of your credit history over time, which is a factor scoring models weigh. A card with no annual fee is generally worth keeping open even if you rarely use it, as long as you can resist spending on it unnecessarily.
Myth
Your income directly affects your credit score.
Fact
Income is not part of any standard credit score calculation. Scores measure how you manage credit, not how much you earn.
FICO and VantageScore models are built entirely from credit report data, and income does not appear on credit reports. A high earner who misses payments will score lower than a modest earner with a spotless payment record. Lenders may consider income separately when evaluating a loan application to assess your ability to repay, but that is a lending decision distinct from the credit score itself. Conflating the two leads people to assume a raise will fix a poor score, when the real work is in managing payment history and utilization.
Myth
A credit score above 700 guarantees loan approval.
Fact
Lenders set their own approval criteria that go beyond the score, including debt-to-income ratio, employment history, and the specific loan type.
A score of 700 or higher places you in a range that many lenders consider acceptable, but no score guarantees approval. Each lender applies its own underwriting standards. A mortgage lender, for example, will also examine your debt-to-income ratio (monthly debt payments divided by gross monthly income), employment stability, assets, and the loan-to-value ratio on the property. Someone with a 740 score and a high debt load may face stricter terms than someone with a 710 score and a low debt-to-income ratio. The score is one input, not a pass/fail switch.
What actually moves the needle on your score
The single largest factor in FICO scoring is payment history, which accounts for roughly 35 percent of the score. Amounts owed (your credit utilization across accounts) is the second largest at about 30 percent. Length of credit history, new inquiries, and credit mix make up the remaining 35 percent in varying weights.
Practical steps that follow directly from these weights: pay every bill on time, keep utilization below 30 percent of each card's limit (lower is generally better), and think carefully before closing accounts you no longer use actively. If you are planning a major purchase that requires financing, avoid applying for new credit in the months before, since each hard inquiry can shave a few points off your score temporarily.
Errors on your credit report are common
The Federal Trade Commission has found in consumer studies that a significant share of credit reports contain errors. You are entitled under federal law to one free credit report from each bureau annually through the official government-authorized channel. Review all three reports regularly and dispute any inaccuracies in writing, since an error in the amounts owed or payment history section can meaningfully depress your score with no action on your part.
