Credit Score Myths Debunked

Credit score misinformation is everywhere — on social media, in Reddit threads, from well-meaning friends. These myths cost people real money and delay real progress. Here are the ones we hear most often, corrected.

Myth 1: Checking Your Own Credit Hurts Your Score

False. Checking your own credit creates a "soft inquiry" which has zero impact on your score. Only "hard inquiries" — from lenders when you apply for credit — affect your score. You can check your credit report and score as often as you like with no consequences. In fact, you should check it at least once a year to catch errors and fraud.

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

False. Carrying a balance means paying interest — it provides zero benefit to your credit score. FICO rewards low utilization (under 10%), and the optimal strategy is to pay your statement balance in full each month. What matters is that a balance is reported at statement close, not that interest accrues.

Myth 3: Closing Old Accounts Improves Your Score

Usually false. Closing a credit card reduces your total available credit, which can spike your utilization ratio. It also reduces your average account age over time. Unless you're paying an annual fee you can't justify, keeping old accounts open and occasionally using them is almost always better for your score.

Myth 4: Income Affects Your Credit Score

False. Your income, employment status, savings, and net worth are not part of your credit score. Two people with identical credit histories will have identical scores regardless of whether one earns $30,000/year and the other earns $300,000/year. Lenders look at income separately during underwriting — it's just not part of the FICO model.

Myth 5: Paying Off a Collection Removes It From Your Report

Usually false. Paying a collection account changes its status from "unpaid" to "paid," but the tradeline remains on your report for 7 years from the original delinquency date. The exception: you can sometimes negotiate removal as a condition of payment (pay-for-delete), and under FICO 9, paid collections are ignored entirely. But paying doesn't automatically delete.

Myth 6: The 30% Utilization Rule Is a Hard Limit

Partly false. 30% is commonly cited as the upper limit for "good" credit, but it's not a threshold — it's a point on a continuous scale. Lower is better. 10% is significantly better than 25%, and under 5% is optimal for maximum scoring. Don't aim for 29% thinking you're in the clear.

Myth 7: More Credit Cards Hurt Your Score

Not automatically. Having multiple cards increases your available credit (lowering utilization) and potentially improves your credit mix. The short-term hit from hard inquiries fades within a year. Responsibly managed, having 3–5 cards can actually support a higher score than having just one — as long as you're not carrying high balances on any of them.

Myth 8: A Spouse's Score Affects Yours After Marriage

False. Scores are individual. Getting married does not merge credit files or scores. Joint accounts (credit cards, mortgages) you open together will appear on both reports going forward, and joint applications use both scores — but your existing individual history remains separate.
