14 Credit Score Myths That Are Costing You Money

Why Credit Score Myths Are Expensive

A 50-point difference in your credit score can mean tens of thousands of dollars in extra interest over a 30-year mortgage. On a $350,000 loan, the gap between a 720 and a 670 credit score translates to roughly $40,000 in additional interest payments over the life of the loan. Yet millions of consumers make decisions based on outdated advice, misunderstood rules, and outright fiction about how credit scoring works.

Credit scoring models — primarily FICO and VantageScore — are complex algorithms that weigh dozens of factors. The basic framework is well-documented, but the nuances are poorly understood by the public. Let us separate fact from fiction.

Myth 1: Checking Your Own Score Hurts It

The Truth: Checking your own credit report or score is a soft inquiry and has zero impact on your credit score. You can check daily if you want. This myth keeps people in the dark about their credit health — the opposite of what helps.

What does cause a small dip is a hard inquiry, which happens when you apply for new credit. Even then, each hard inquiry typically costs only 3 to 5 points and falls off your score after 12 months (though it remains on your report for two years).

Myth 2: You Need to Carry a Balance to Build Credit

The Truth: This is the single most expensive myth in personal finance. You do not need to pay a penny in interest to build or maintain an excellent credit score. Credit scoring models evaluate whether you make payments on time and how much of your available credit you are using — not whether you carry a balance month to month.

Paying your statement balance in full every month is the optimal strategy. You demonstrate responsible use, avoid interest charges entirely, and keep your utilization ratio low. Carrying a balance does nothing positive for your score and costs you money.

Myth 3: Closing Old Cards Improves Your Score

The Truth: Closing an old credit card almost always hurts your score, for two reasons. First, it reduces your total available credit, which increases your overall utilization ratio. If you have $20,000 in total credit limits and $4,000 in balances, your utilization is 20%. Close a card with a $5,000 limit and your utilization jumps to 27% — enough to cost you 20 or more points.

Second, closing an old account can eventually reduce your average age of accounts, which makes up about 15% of your FICO score. A card you have held for 12 years contributes significantly to a long credit history. The better strategy: keep old cards open, put a small recurring charge on them to prevent the issuer from closing them for inactivity, and pay the balance in full each month.

Myth 4: Your Income Affects Your Credit Score

The Truth: Your income, savings, investment accounts, and net worth are not factors in any credit scoring model. Credit scores measure credit behavior — how you borrow and repay — not how much money you earn. A person earning $40,000 per year with perfect payment history and low utilization can have a higher credit score than someone earning $400,000 who misses payments.

Income does affect your ability to get approved for credit (lenders evaluate it separately), and it plays a role in the credit limit you are offered. But the score itself is income-blind.

Myth 5: All Debt Is Treated Equally

The Truth: Credit scoring models distinguish between types of debt. Revolving debt (credit cards) has a much larger impact on your score than installment debt (mortgages, auto loans, student loans). High credit card utilization can drop your score by 50 to 100 points, while a mortgage with a similar balance relative to the original amount has minimal impact.

Additionally, credit mix — having a variety of account types — makes up about 10% of your FICO score. Having only credit cards is less favorable than having credit cards plus an installment loan, though you should never take on debt just to diversify your credit mix.

Myth 6: Paying Off Collections Removes Them From Your Report

The Truth: Paying a collection updates its status to "paid" but doesn't remove it from your credit report. It stays for 7 years from the original delinquency, paid or unpaid. Medical debt is the exception: the three bureaus delete a medical collection once it's paid. Whether paying helps your score depends on the model. FICO 9, FICO 10 and VantageScore 3.0 and 4.0 ignore paid collections, so paying one can lift those scores right away. FICO 8 and the Classic FICO scores most mortgage lenders still use keep counting it.

If you want the collection gone, you can ask the agency for a "pay-for-delete" agreement before paying: it asks the bureaus to remove the account in exchange for your payment. Many agencies refuse, and the bureaus' reporting rules discourage deleting accurate information, so get any agreement in writing first. Applying for a mortgage? Ask which score the lender uses: since September 9, 2026, lenders selling loans to Fannie Mae and Freddie Mac may use VantageScore 4.0, which ignores paid collections.

Myth 7: Shopping for Loans Destroys Your Score

The Truth: Credit scoring models are designed to encourage rate shopping. Multiple inquiries for the same type of loan — mortgage, auto, or student loan — within a defined window (14 to 45 days depending on the scoring model) are counted as a single inquiry. FICO 8, the most commonly used version, uses a 45-day window.

This means you can get quotes from five different mortgage lenders in the same month and only receive one inquiry hit to your score. The key is to do your shopping within the window. Credit card applications are not grouped this way because each application represents a separate line of credit.

Myth 8: You Only Have One Credit Score

The Truth: You have dozens of credit scores. FICO alone has several versions in use (FICO 8, FICO 9, FICO 10 and 10T, industry versions for auto and card lending, and the older Classic FICO scores built for mortgages), and VantageScore has 3.0 and 4.0. Each version can be run on each bureau's file, and the files differ. The score your card company shows you for free may be a VantageScore, while your mortgage lender pulls something else, and they won't match. Mortgages changed in 2026: lenders selling to Fannie Mae or Freddie Mac may now use VantageScore 4.0 instead of Classic FICO, and FHA adds VantageScore 4.0 and FICO 10T on January 1, 2027.

What matters is the trend, not any single number. If all your scores are generally in the same range and trending in the same direction, you have a clear picture of your credit health.

Myth 9: Married Couples Share a Credit Score

The Truth: There is no such thing as a joint credit score. Marriage does not merge your credit reports or scores. Each spouse maintains an individual credit file. However, any joint accounts — a mortgage, a joint credit card, an auto loan with both names — will appear on both credit reports. If one spouse misses a payment on a joint account, both credit scores take the hit.

This is why it is critical to review both credit reports before applying for a mortgage together. The lender will use both scores and typically bases the decision on the lower score of the two applicants.

Myth 10: Debit Cards Build Credit

The Truth: Debit cards are linked to your bank account and are not credit products. They are not reported to the credit bureaus and have no effect on your credit score — positive or negative. Using your debit card responsibly does not build credit history.

If your goal is to build credit, you need a product that reports to the bureaus: a credit card, a credit-builder loan, or being added as an authorized user on someone else's credit card. Secured credit cards, which require a deposit equal to your credit limit, are the most accessible option for people starting from scratch or rebuilding after negative events.

Myth 11: Employers Can See Your Credit Score

The Truth: Employers can request a modified version of your credit report (with your written permission), but they cannot see your credit score. The report they receive is also stripped of information like your date of birth and account numbers. Employers use credit checks primarily for positions involving financial responsibility — accounting, banking, government security clearances — not for general hiring.

Some states and cities have restricted or banned employment credit checks altogether. Check your state laws before consenting to one.

Myth 12: Bankruptcy Means Bad Credit Forever

The Truth: Bankruptcy is devastating to your credit score initially — expect a drop of 130 to 240 points. But the impact diminishes steadily over time. Chapter 7 bankruptcy remains on your report for 10 years; Chapter 13 for 7 years. However, many people see their score recover to the mid-600s within 2 to 3 years of filing, especially if they rebuild with a secured credit card and maintain perfect payment history on any new accounts.

Bankruptcy does not lock you out of credit entirely. Some credit card issuers offer secured cards to people in active bankruptcy. The key is to begin rebuilding immediately and consistently.

Myth 13: Buy Now, Pay Later Can't Touch Your Credit

The Truth: Pay-in-4 plans used to stay off credit reports, and many still do, but that's changing. Affirm began reporting all of its loans, including Pay in 4, to Experian for plans started from April 1, 2025. In June 2025 FICO introduced FICO Score 10 BNPL and 10T BNPL, versions that count these loans; in FICO's testing most people's scores moved by about 10 points or less either way.

Most scores lenders use today still don't count BNPL loans, so on-time payments may not help much yet. Missed ones can hurt anyway: a plan you stop paying can be sent to collections, and a collection lowers every score. Treat each plan as a loan. Our buy now, pay later guide shows how overlapping plans pile up.

Myth 14: Medical Debt Was Wiped Off Credit Reports in 2025

The Truth: It wasn't. The CFPB finalized a rule in January 2025 that would have removed medical bills from credit reports, but a federal court in Texas vacated it on July 11, 2025, before it took effect. What protects you instead are three voluntary bureau policies: paid medical collections are deleted, new medical collections don't appear until a year has passed, and medical collections under $500 aren't reported at all.

That leaves unpaid medical collections of $500 or more. Roughly 15 states have laws that go further, but in October 2025 the CFPB said federal law overrides state limits on what a credit report can contain, which puts those laws in doubt. The damage also depends on the model: VantageScore 3.0 and 4.0 ignore medical collections, FICO 9 and 10 give them less weight, and FICO 8 and Classic FICO count them like any other collection.

What Actually Moves Your Credit Score

Now that the myths are cleared, here is what the data shows matters most, in order of impact on your FICO score.

If you focus on paying every bill on time and keeping your credit card utilization below 30% (ideally below 10%), you are addressing 65% of your score. The rest takes care of itself with time and responsible use.

Those weights are FICO's. VantageScore weighs similar information differently, and the trended models (FICO 10T and VantageScore 4.0) also look at how your card balances moved over the last 24 months, so a steady paydown counts for more there than a payoff the week before you apply.

Paying the bill on time does not lower the balance your card reports; paying before the statement closes does. The Credit Utilization Optimizer builds that plan for you.
