How to Choose the Right 0% APR Card
1. Consider Your Credit Score
Most 18-month 0% APR cards require good to excellent credit (670+). If your credit score is lower, focus on improving it first.
2. Check Fees and Penalties
Some cards have balance transfer fees (usually 3%-5%) or late fees. Always read the fine print.
3. Look for Additional Perks
Some cards include cash back, mobile protection, fraud coverage, or even travel benefits.
Smart Ways to Use a 0% APR Credit Card
✅ Transfer Debt Immediately
The sooner you transfer, the more interest you save. Many cards offer 0% APR only for transfers made in the first 60-120 days.
✅ Pay More Than the Minimum
Break your total balance into 18 equal monthly payments. Paying just the minimum can keep you in debt longer.
✅ Set Calendar Alerts
Mark the end of the 0% APR period so you don’t get caught off guard.
✅ Avoid New Purchases (if you transferred debt)
Some cards prioritize new purchases over transferred balances, complicating repayment.

Common Mistakes to Avoid
Overspending
Zero interest doesn’t mean free money. It’s easy to rack up a bigger balance thinking you’re not paying interest.
Missing a Payment
Missed payments can void your 0% APR offer and trigger penalty interest rates.
Ignoring the Expiry Date
Once the intro period ends, you might be hit with 20%+ APR. Be prepared to pay off or refinance.
