1. Carrying a Balance Instead of Paying in Full

One of the most common misconceptions is that you need to carry a balance to build credit. This is false.

• The Mistake: Paying only the minimum balance and letting debt accumulate.
• The Consequence: You’ll pay high interest rates (often 20–30% APR), making everyday purchases much more expensive.
• The Fix: Always pay your balance in full each month to avoid interest charges.

---

2. Missing or Making Late Payments

Payment history makes up 35% of your credit score. Missing just one payment can hurt your score significantly.

• The Mistake: Forgetting due dates or paying late.
• The Consequence: Late fees, penalty APRs, and negative marks on your credit report.
• The Fix: Set up autopay or reminders to ensure you never miss a payment.

3. Maxing Out Your Credit Card Limit

Your credit utilization ratio—the percentage of available credit you’re using—is a key factor in your credit score.

• The Mistake: Using too much of your available credit.
• The Consequence: High utilization lowers your credit score and signals risk to lenders.
• The Fix: Keep utilization under 30% (ideally under 10%).

---

4. Applying for Too Many Credit Cards at Once

• The Mistake: Submitting multiple credit card applications in a short time.
• The Consequence: Each application triggers a hard inquiry, which can lower your score.
• The Fix: Apply strategically and only for cards that fit your financial needs.

5. Ignoring Fees and Terms

Many people don’t read the fine print.

• The Mistake: Overlooking annual fees, balance transfer fees, or foreign transaction fees.
• The Consequence: Unexpected charges and higher costs.
• The Fix: Always review terms before applying and compare cards carefully.

6. Using Credit Cards for Cash Advances

• The Mistake: Withdrawing cash using your credit card.
• The Consequence: High fees and immediate interest charges.
• The Fix: Use a debit card or emergency fund for cash needs.

---

7. Closing Old Credit Card Accounts

• The Mistake: Canceling old cards to “simplify” finances.
• The Consequence: Shorter credit history and reduced available credit, lowering your score.
• The Fix: Keep old accounts open unless they have high fees.

---

8. Falling for Minimum Payment Traps

Credit card companies often highlight the minimum payment option.

• The Mistake: Paying only the minimum.
• The Consequence: Debt snowballs, and interest costs multiply.
• The Fix: Pay more than the minimum—ideally the full balance.

---

9. Overspending to Chase Rewards

• The Mistake: Buying more than you need just to earn points, miles, or cashback.
• The Consequence: Debt outweighs rewards.
• The Fix: Treat rewards as a bonus, not a reason to overspend.

---

10. Not Monitoring Statements and Credit Reports

• The Mistake: Ignoring your monthly statement.
• The Consequence: Fraudulent charges or errors can go unnoticed.
• The Fix: Check statements and monitor your credit report regularly.

---

11. Using Only One Credit Card

• The Mistake: Relying on one card for everything.
• The Consequence: Higher utilization and missed opportunities for diversified rewards.
• The Fix: Maintain 2–3 well-chosen cards to spread spending and benefits.

---

12. Not Understanding APR and Interest

• The Mistake: Assuming interest rates don’t matter.
• The Consequence: Paying hundreds or thousands in unnecessary interest.
• The Fix: Always check APR, and avoid carrying balances.
