Top 10 Credit Card Mistakes You’re Probably Making (And How to Fix Them)

Hey there, money-savvy friends! Welcome back to Wealthy Swipe—your trusted guide to making credit cards work for you, not against you. Whether you’re in the UK, US, or Canada, credit cards can be a game-changer… if you use them right.

But let’s be real—most of us mess up at some point. Maybe you’ve missed a payment, carried a balance, or ignored rewards (free money, people!). The good news? These mistakes are totally avoidable.

So, grab your favorite drink, settle in, and let’s break down the top 10 credit card blunders—plus exactly how to dodge them like a pro.

1. Carrying a Balance (AKA Feeding the Interest Monster)

We’ve all been there—life happens, and suddenly, you’re only paying the minimum. But here’s the ugly truth: Credit card interest rates are brutal (we’re talking 20%+ APR). Let that balance linger, and you’re basically throwing money into a black hole.

Fix It Fast:

• Pay in full every month. No excuses. If you can’t, you’re spending too much.

• If you’re stuck with debt, switch to a 0% balance transfer card (check out options like Chase Slate or MBNA in the UK).

• Set up autopay—because forgetting is way too easy.

2. Missing Payments (And Tanking Your Credit Score)

One late payment = late fees + a credit score nosedive. And no, your bank won’t always remind you.

Fix It Fast:

• Put due dates in your phone with obnoxious alarms.

• Autopay the minimum (better than nothing).

• If you do miss one, call your issuer ASAP. Sometimes they’ll waive the fee (just ask nicely).

3. Maxing Out Your Card (The Quickest Way to Hurt Your Score)

Using 90% of your limit? Big mistake. Credit bureaus hate that. Experts say keep it under 30%, but under 10% is the sweet spot.

Fix It Fast:

• Pay early (before your statement closes).

• Ask for a limit increase (if you’ve had the card awhile).

• Spread spending across cards if you have more than one.

4. Ignoring Rewards (Why Say No to Free Money?)

If you’re not using rewards, you’re leaving hundreds of dollars (or pounds!) on the table. Cashback, travel points, discounts—they’re all up for grabs.

Fix It Fast:

• Pick a card that fits your spending (travel? groceries? gas?). Compare options on NerdWallet or MoneySavingExpert.

• Stack bonuses (like Amex Offers or Chase’s 5% categories).

• Redeem wisely—some points are worth way more for flights than gift cards.

5. Applying for Too Many Cards at Once

Each application dings your credit score. Do it too much, and lenders think you’re desperate for cash (not a good look).

Fix It Fast:

• Space out applications (every 3-6 months).

• Check pre-approvals first (soft pulls don’t hurt).

• Focus on long-term keepers, not just sign-up bonuses.

6. Never Checking Your Credit Report

Mistakes happen. A wrong late payment or fraudulent account could be dragging your score down—and you’d never know.

Fix It Fast:

• Check your report FREE (Experian, Credit Karma, Borrowell in Canada).

• Dispute errors immediately (it’s easier than you think).

• Monitor regularly—identity theft is no joke.

7. Falling for “No Interest” Store Card Traps

That “0% for 12 months!” deal at the checkout? Trap. Miss the deadline, and boom—you owe back interest on the whole amount.

Fix It Fast:

• Skip store cards (unless you’re sure you’ll pay in time).

• Use a real 0% APR card instead (like Citi Simplicity).

• Mark the deadline in bold red on your calendar.

8. Forgetting Sign-Up Bonuses

Some cards offer 50,000+ points just for spending a bit upfront. Missing that? Like declining free cash.

Fix It Fast:

• Time big purchases (hello, new card bonus).

• Never spend extra just to hit the bonus (defeats the purpose).

• Track deadlines like your life depends on it.

9. Closing Old Cards (The Silent Credit Killer)

Your oldest card helps your credit history. Close it, and your score might drop.

Fix It Fast:

• Keep it open (even if you don’t use it much).

• Use it for a small subscription (Netflix?) to keep it active.

• Downgrade to a no-fee card instead of closing.

10. Ignoring Fraud Alerts

Scammers love credit cards. If you’re not watching, you could be paying for someone else’s shopping spree.

Fix It Fast:

• Turn on transaction alerts (texts > emails—you’ll actually see them).

• Use virtual cards for sketchy sites (Capital One Eno is great for this).

• Freeze your credit if things look fishy.

Bottom Line: Small Tweaks, Big Wins

Credit cards aren’t evil—misusing them is. Ditch these mistakes, and you’ll build credit, earn rewards, and avoid debt.
