Credit Score Myths Debunked: What Actually Helps and Hurts
In more than a decade of guiding people through credit rebuilds, mortgage approvals, and post-divorce financial resets, I’ve watched the same misconceptions derail progress year after year.
Clients arrive convinced that one wrong move will ruin them forever, or that some old family tip will unlock instant gains.

Credit scoring models like FICO and VantageScore evolve slightly over time, but the core drivers remain remarkably consistent: your track record of reliability. Here are the myths I encounter most often, along with the real-world truths that actually move the needle.
Myth: Checking Your Own Credit Score Will Hurt It
This one tops the list. I’ve had clients go years without looking at their reports because an aunt or uncle warned that every check dings the score. The fear is real, but misplaced.
When you pull your own credit score or report through AnnualCreditReport.com, your bank app, or a service like Credit Karma, it’s always a soft inquiry. Soft inquiries have zero impact on your score, no matter how often you check. Hard inquiries, triggered by applications for new credit, can cause a temporary dip of a few points, usually recovering within months.
One client, a first-time homebuyer in his late 20s, refused to review his score before pre-approval, terrified of the “hit.” When he finally checked, he spotted an old collection that wasn’t his.
We disputed it successfully, and his score rose enough to qualify for a lower interest rate. Regular monitoring catches errors early and builds confidence. Ignorance rarely helps, knowledge almost always does.
Myth: Carrying a Balance on Credit Cards Builds Your Score
People hear this everywhere: “Leave a little owing to show you’re using credit.” It sounds logical, but it’s one of the most expensive myths.
Paying interest month after month to chase a supposed benefit is unnecessary and counterproductive. What matters far more is your credit utilization ratio, the percentage of your available credit you’re actually using. This factor weighs heavily, often around 30 percent in scoring models.
The sweet spot is keeping utilization below 30 percent, ideally in the single digits for the biggest boosts. I once worked with a teacher who carried $4,000 on a $5,000-limit card every month, paying minimums plus interest.
Her utilization hovered near 80 percent, dragging her score down despite perfect payments. We shifted her to paying the full balance each month. Within two cycles, utilization fell sharply, and her score jumped by more than 80 points. No interest paid, no tricks needed. Pay in full whenever possible; it’s the responsible habit lenders reward.
Myth: Closing Old Credit Cards Simplifies Things and Won’t Hurt
Clients often say, “I’m not using this old card anymore, might as well close it.” It feels tidy, but it can backfire in two ways.
First, closing reduces your total available credit, which spikes utilization even if your spending doesn’t change. Second, it shortens your average credit history, a factor that accounts for about 15 percent of your score.
A client in her 40s closed a 12-year-old card after paying it off, thinking it was harmless housekeeping. Overnight, her utilization jumped from 18 percent to 42 percent across her remaining cards, and her score dropped 35 points.
The history hit lingered too. Unless there’s an annual fee eating into your budget or you’re worried about fraud or temptation, keep old accounts open. Make a small purchase every few months and pay it off to keep them active. Dormant but open is better than gone.
Myth: Higher Income Automatically Means a Higher Credit Score
This feels intuitive: earn more, handle money better. But income isn’t part of any major scoring model. FICO and VantageScore look only at credit behavior, not your paycheck.
I’ve seen high earners with six-figure salaries tank scores through lifestyle inflation, maxed cards, and missed payments during bonuses that vanished. Conversely, clients on modest incomes built excellent scores through strict habits: autopay, low balances, and no unnecessary applications.
Focus on what you control, not what you earn. Behavior trumps bank balance every time.
What Actually Helps Your Credit Score
The biggest gains come from consistency in the factors that matter most. Payment history is king, usually around 35 percent or more, depending on the model.
One 30-day late payment can drop your score significantly and stay on your report for seven years, though its impact fades as you rack up on-time payments. Set up autopay for at least the minimum amount, ideally the full statement balance, and treat due dates as non-negotiable bills.
Next is utilization: pay down revolving debt aggressively. Dropping from high to low utilization often delivers the fastest visible lift.
Keeping old accounts helps preserve historical length. A mix of credit types, like cards plus an auto loan or mortgage, can add a small edge, but don’t open new accounts solely for this. Limit new applications to avoid clustering hard inquiries, which signal risk.
What Hurts the Most (and How to Avoid It)
Late payments top the damage list, followed by high utilization and collections. I’ve seen small unpaid medical bills balloon into collections, haunting scores for years.
Dispute inaccuracies immediately through the bureaus, and if a collection is legitimate, negotiate a pay-for-delete agreement when possible. Space out credit applications, especially during big life moves like buying a home.
Improving credit isn’t about gaming the system with shortcuts. It’s about steady, boring reliability: pay on time, keep balances manageable, monitor your reports, and avoid impulsive risks.
In my experience, the clients who see the most lasting progress treat these habits like daily routines rather than temporary fixes. Do that consistently, and the three-digit number rises naturally. No myths, no drama, just results.
