Key Takeaways
- Checking your own credit score never lowers it — only hard inquiries from lenders can.
- Carrying a credit card balance does not build credit and adds unnecessary interest costs.
- Closing an old credit card can actually hurt your score by reducing available credit and account age.
- A perfect 850 score and a 760 score typically unlock the same lender rates and terms.
- Paying bills on time is the single most powerful action you can take to improve your score.
Why Credit Score Myths Persist
Credit scores shape everything from mortgage approvals to car loan interest rates — yet many people operate on assumptions that were never accurate to begin with. Some myths started as misunderstandings of real concepts; others were passed along as folk wisdom. The result is that well-intentioned financial behaviour sometimes quietly works against the very outcome people are trying to achieve.
Understanding what a credit score actually measures is a necessary starting point. The score is a statistical summary of your borrowing history — nothing more, nothing less. It does not reflect your worth, your income, or your general financial health. With that foundation in place, the myths below become easier to evaluate clearly.

The Myths — and What's Actually True
The following myth-and-fact pairs address the misconceptions most likely to cause real harm if acted upon. Each correction is grounded in how scoring models are publicly documented to work.
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.
There are two types of credit inquiries: soft and hard. A soft inquiry occurs when you check your own score, or when a lender pre-screens you without your application. A hard inquiry occurs when you formally apply for new credit — a card, loan, or mortgage — and the lender pulls your report to make a decision. Only hard inquiries can temporarily lower your score, typically by a few points. Monitoring your own credit regularly is not only harmless but encouraged, because catching errors early protects you. See how your credit report and score relate for more on what each pull actually shows.
Myth
Carrying a small balance on your credit card helps build credit.
Fact
Paying your balance in full each month builds credit just as effectively — and saves you money in interest.
This myth likely spread because people conflate using credit with owing credit. What scoring models reward is consistent, on-time payment behaviour and responsible utilisation — not the act of carrying a revolving balance. When you carry a balance, the card issuer charges interest, which earns you nothing from a scoring perspective. Keeping your credit utilisation ratio (the percentage of available credit you're using) below roughly 30% is helpful; paying the balance in full keeps utilisation low without costing you interest. For a full breakdown of what actually moves the needle, see the five factors behind your credit score.
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 average account age — both of which can lower your score.
When you close a credit card, two things happen that can work against you. First, your total available credit drops, which pushes your utilisation ratio higher 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 — another factor scoring models weigh positively. This doesn't mean you should never close a card, but the decision deserves careful thought. Why closing old credit cards can hurt your score walks through the full mechanics.
Myth
You need a perfect 850 credit score to get the best rates.
Fact
Most lenders reserve their best rates for scores above a certain threshold — often around 760 — not exclusively for perfect scores.
Credit scoring scales — such as the FICO® scale of 300–850 — are used by lenders to bucket applicants into risk tiers. Once a borrower crosses into the top tier, they generally qualify for the same rates regardless of whether their score is 760 or 850. Chasing a perfect score can cause unnecessary stress and rarely produces a measurable financial benefit. A more practical goal is consistent, healthy credit habits: paying on time, keeping utilisation reasonable, and not applying for multiple new accounts at once.
Myth
Income affects your credit score.
Fact
Credit scores are calculated entirely from credit behaviour — income is not a factor.
Credit scores reflect how you manage borrowed money, not how much you earn. Payment history, amounts owed, length of credit history, credit mix, and new inquiries are the five core inputs. Income doesn't appear on your credit report and plays no role in the score calculation. That said, lenders often consider income separately when evaluating loan applications, because they want to assess your ability to repay — but this is a lender-level decision, not a score input. If you're new to credit entirely, building credit from zero explains realistic first steps regardless of your earnings level.
Myths Can Have Real Financial Costs
Acting on credit score misconceptions — such as deliberately carrying a balance or closing old accounts — can result in higher interest rates, reduced borrowing power, or a score that drops unexpectedly. Understanding the mechanics before making changes to your credit behaviour is worth the effort.
Credit scoring also plays a direct role in major purchases. If you're considering financing a vehicle, understanding what your credit score does to your car loan illustrates just how much a few score points can affect the total cost of borrowing.
What Actually Moves Your Score
With the myths cleared away, the path to a strong credit score is straightforward, if not always fast:
5 factors
Inputs that determine a FICO credit score
Payment history, amounts owed, length of credit history, new credit, and credit mix are the only variables in standard FICO score calculations.
~30%
Utilisation ratio widely cited as a healthy ceiling
Credit counsellors and financial educators generally recommend keeping your credit utilisation below 30% of your available limit to support a strong score.
35%
Weight of payment history in FICO scoring
According to FICO's publicly published scoring criteria, payment history is the single largest factor, comprising approximately 35% of the total score.
- Pay on time, every time. Payment history carries more weight than any other factor. A single missed payment can cause a meaningful drop and remain on your report for up to seven years.
- Keep balances low relative to your limits. Utilisation matters month to month. Paying down balances before your statement closes can improve the ratio reported to bureaus.
- Be selective about new credit applications. Each hard inquiry has a small, temporary effect — but multiple applications in a short window can add up.
- Let accounts age. Older accounts strengthen your credit history. Avoid closing them without a clear reason.
Credit improvement is incremental. There are no shortcuts that work reliably, and any service claiming to instantly repair or dramatically boost a score deserves serious scrutiny. Consistent habits over time remain the most durable strategy.
