5 Credit Card Myths to Avoid

Credit cards generate a remarkable amount of misinformation. Some myths are harmless — they just lead to suboptimal choices. Others actively cost people money, damage credit scores, or lead to debt that compounds for years. The five below are the ones I see most often in my work, and the ones where getting the facts right makes the biggest practical difference.

Myth 1: Carrying a Balance Helps Your Credit Score

This is one of the most persistent myths in personal finance, and it's completely false.

The belief usually goes: "You have to show you're using the credit — if you pay off the balance every month, the card issuer doesn't make money and they'll close your account or it won't help your credit."

Here's what's actually true: paying your statement balance in full every month does nothing negative to your credit score. The credit bureaus track payment history (whether you pay on time) and utilization (how much of your available credit you're using). Paying in full demonstrates perfect payment history and keeps utilization low — both positive for your score.

Carrying a balance at 22–27% APR costs real money in interest every month. It does not help your credit score. The myth is so widespread that it's genuinely costly: millions of people pay unnecessary interest based on something that was never true.

Pay in full every month. Keep utilization low. Your score will be better, not worse.

Myth 2: Closing a Credit Card Improves Your Credit Score

The intuition here makes sense: if you have too much available credit, closing some of it should make you look more responsible, right?

In practice, closing a credit card typically hurts your score in two ways.

First, it reduces your total available credit, which increases your credit utilization ratio. If you have $20,000 in total available credit and $4,000 in balances, your utilization is 20%. Close a card with a $5,000 limit and your available credit drops to $15,000 — utilization jumps to 26.7% with no change in your actual debt.

Second, closing older accounts can reduce your average account age once the closed account eventually ages off your report. Length of credit history is a meaningful factor in your score.

There are legitimate reasons to close a card — an annual fee you're not getting value from, a card that creates spending temptation you can't manage — but "it'll help my credit score" isn't one of them. If you want to reduce the temptation of an unused card without closing it, cut up the physical card and keep the account open.

Myth 3: You Only Have One Credit Score

You have dozens. The credit reporting ecosystem is more complex than most people realize.

There are three major credit bureaus — Equifax, Experian, and TransUnion — each maintaining a separate file on you that can contain different information. Creditors don't all report to all three bureaus. An account that's on your Experian report may not appear on your TransUnion report at all.

Beyond the three bureaus, there are multiple scoring models: FICO has over 50 score versions, including industry-specific versions for mortgage lenders, auto lenders, and credit card issuers. VantageScore is a competing model developed by the bureaus themselves. The score your bank shows you in their app may be a VantageScore; the score a mortgage lender pulls may be FICO 2, 4, or 5 — each producing different numbers from the same underlying data.

The practical implication: a single score check doesn't give you the complete picture. If you're preparing for a major credit application — mortgage, car loan — it's worth knowing that lenders may pull a different score than the one you're monitoring. Check all three bureau reports and understand that the score you see may not be the score a specific lender sees.

Myth 4: The Minimum Payment Is Designed to Help You Pay Off Your Balance

The minimum payment is designed to keep your account current — to prevent late fees and negative credit reporting. It is not designed to help you pay off your balance. The difference matters enormously.

On a $5,000 credit card balance at 24% APR, the minimum payment might be $100–$125/month. At that payment, a large portion of each payment covers interest, with very little going toward the principal. Paying only the minimum can extend the payoff timeline to a decade or more — and the total interest paid can exceed the original balance.

The minimum payment trap isn't accidental — issuers set minimum payments at a level that keeps accounts current while maximizing the interest revenue generated by slow-moving balances. Understanding this reframes the question from "can I afford the minimum?" to "what payment actually makes meaningful progress?"

Even doubling or tripling the minimum payment dramatically shortens the payoff timeline and reduces total interest paid. Treating the minimum as a target rather than a floor is one of the most common and expensive credit card mistakes people make.

Myth 5: A High Income Means You Won't Have Credit Card Debt Problems

Income and credit card debt are correlated, but not as simply as people assume. High earners carry significant credit card debt at rates that would surprise most people — because lifestyle inflation, spending patterns, and the psychological relationship with credit don't automatically scale with income.

More importantly, a high income doesn't protect you from the mechanics of high-interest revolving debt. A $50,000 credit card balance at 24% APR costs $12,000/year in interest regardless of whether you earn $60,000 or $600,000. The scale of the problem is proportional to the balance and the rate — not the income.

What income does is affect how long it takes the debt to become unmanageable and what resolution options are available. High-income earners often have more path options — they can more aggressively pay down balances, or they can qualify for consolidation at better rates. But they're not immune to the underlying mechanics, and the belief that income shields you from debt problems is part of why high earners sometimes carry balances for years without addressing them.

The Myth That Runs Underneath All of These

Every myth above has a common thread: each one makes carrying a credit card balance seem more benign than it is, or makes addressing it seem unnecessary or complicated. That's useful to credit card issuers whose revenue depends on revolving balances. It's not useful to cardholders.

The straightforward truth: credit cards are tools that deliver real value when paid in full monthly. When they accumulate balances at high APRs, the cost compounds quickly and the standard advice stops working. At that point, the options are aggressive paydown, debt consolidation, debt settlement, or a debt relief program — depending on the scale of the balance and what the income can support. Our guide on how to pay off credit card debt covers each approach in detail.

Frequently Asked Questions

If carrying a balance doesn't help my credit score, why do so many people believe it does?

The myth may have originated from the idea that credit card companies prefer customers who carry balances (which is true — it's how they make money) and that you need to "use" the credit to get the benefit (partially true — activity does help prevent account closure). Somewhere along the way, "use the card occasionally" became "carry a balance," and the false version spread. There's no credit bureau formula in which carrying a balance at high interest benefits your score.

Does applying for a new credit card hurt my score significantly?

A new credit card application creates a hard inquiry, typically causing a 5–10 point temporary dip. The new account also reduces average account age. Both effects are modest and temporary — most people recover within 3–6 months of responsible use. The longer-term effects of a new card (additional available credit, payment history opportunities) typically outweigh the short-term dip for people who manage the card well.

What's the best number of credit cards to have?

There's no universally optimal number — it depends on how well you manage each one. From a credit scoring perspective, having two or three cards in good standing (paid in full monthly, low utilization) is typically better than having one. The diversity helps with credit mix and provides more available credit, reducing utilization. More than five cards starts to create management complexity without proportional credit score benefit.

Is a 0% APR promotional offer worth it?

Yes — with conditions. A 0% promotional APR on purchases or balance transfers eliminates interest for the promotional period (typically 12–21 months). This is genuinely valuable for paying down an existing balance without interest accumulation, provided you: know the exact end date of the promotional period, have a concrete plan to pay the balance before the promotion expires, and don't use the 0% window as an excuse to add new charges.

What happens to my credit score if I stop using a credit card?

Inactive accounts are sometimes closed by the issuer for inactivity, which would affect your available credit and account history. To prevent this, use the card for a small recurring charge (a streaming subscription, a monthly bill) and pay it off automatically. This keeps the account active and reporting positively without creating any balance risk.
