The One Credit Card Trick That Can Change Your Score

Have you ever heard someone say, “All you need is one credit card to build your credit”? It sounds simple enough—and in some ways, it’s true. But like most credit advice, the reality is a little more complicated. Let’s break down how this “one card trick” works, where it falls short, and how you can really use it to your advantage.

What Is the “One Credit Card Trick”?

The idea is simple: open one credit card, keep it in good standing, and use it responsibly. For many people, this means:

• Making small purchases

• Paying the balance in full every month

• Keeping the account open long-term

  
  

On the surface, it makes sense. You’re showing lenders that you can manage credit without juggling multiple accounts. But does it really build a strong credit profile?

Why This Trick Does Work

There are some real benefits to having even just one credit card:

• Payment History (35% of your score): Paying your card on time builds a positive history.

• Credit Utilization (30% of your score): Keeping your balance low (ideally under 30%) helps your score.

• Length of History: The longer your account stays open, the stronger your average account age becomes.

So yes, one credit card can definitely help you start your credit journey.

Why It Doesn’t Work Alone

The problem? Credit scoring models look at more than just one tradeline. Here’s where the one-card trick falls short:

• Limited Credit Mix (10% of your score): Lenders want to see a variety—like installment loans and revolving accounts—not just one card.

• Thin File Risk: With only one card, your report has very little data. That makes it harder to qualify for bigger loans.

• What If That Card Closes?: If your one account gets closed, you lose all that history and your score can drop overnight.

The Better Approach

Think of one credit card as your starting block, not your entire foundation. Here’s how to build beyond it:

• Add a secured card or retail card once you’re comfortable.

• Consider a credit builder loan to diversify your profile.

• Always keep utilization low and payments on time.

• Monitor your credit score progress with a trusted tool like IdentityIQ.

This balanced approach strengthens every part of your score—not just one piece of the puzzle.

The Bottom Line

One credit card is better than none, but it’s not the magic bullet to perfect credit. Use it wisely, then take the next steps to diversify and grow your credit profile.
