How to Build Credit With a Credit Card

Used well, a credit card is one of the fastest and cheapest ways to build a strong credit history in the US and Canada. Used badly, it's also one of the fastest ways to damage it. The mechanics are simple once you know what the scoring models actually reward.

The two habits that matter most

• Pay on time, every time. Payment history is the single largest factor in your score. Set autopay for at least the minimum so you never miss a due date.
• Keep utilization low. Try to use less than about 30% of your limit — and ideally under 10% — on the statement that gets reported. You can pay down the balance before the statement closes to keep the reported number low.

If you're starting from scratch

A secured card or a student card is the usual on-ramp. Both report to the credit bureaus, so responsible use builds history even with a small limit. After 6–12 months of on-time payments you can often upgrade to an unsecured card.

What not to do

Don't chase multiple new cards at once, don't max out your limit, and don't close your oldest card without a reason — length of history helps your score. Check your credit report for free and dispute any errors.
