Clark Howard: My 7 Rules for Using Credit Cards


Credit cards can help you build credit, but there are a few rules you must follow to avoid going into debt.

Money expert Clark Howard says that if you don’t have credit, you could suffer in many areas of your financial life. If there’s nothing listed on your credit report, you could face higher interest rates on loans, more expensive insurance premiums and even be denied employment.

In this article, we’ll review Clark’s credit card philosophy and how to use credit cards the right way.

1. Have at Least Two Credit Cards

How many credit cards are in your wallet? Clark recommends that you have two credit cards for a mix of credit, which is an important component of your overall credit score.

He says those cards should be from two different companies.

“If we hit a recession and credit card companies decide they don’t want you and one of them dumps you, you still have the other card. And if one of them cuts back your limit, you still have the other card.”

For couples, Clark says it’s important to have two credit cards per individual — not per household.

Once you have two credit cards from different issuers, you may decide to apply for additional cards — even from the same issuer. Learn more about Clark’s personal credit cards here.

2. Keep Balances Low and Pay Credit Cards Off Monthly 

No matter the number of credit cards you have, you want to keep your balances low and pay them off in full every month. Payment history and amounts owed make up a combined 65% of your FICO score.

If you don’t carry a balance, not only will you avoid paying interest charges, you’ll also likely be eligible for the cards that offer the best rewards.

3. Go With a Cash Back Credit Card

When you’re comparing rewards credit card offers, Clark says simple cash back cards like the Citi Double Cash Card are best. This card offers up to 2% cash back: 1% when you buy and 1% when you pay your bill.


Rewards cards that offer rotating 5% cash back categories are often too complicated to keep up with, Clark says. But if you decide to go this route, here’s a tip that can help.

As for travel rewards credit cards, Clark says you have to consider the annual fees and whether you charge enough on the card to justify the cost. That’s just not the case for most individuals.

However, if you fly a particular full-fare airline regularly, the lowest-tier annual fee card may be worth considering.

4. Know Your Interest Rates 

If you can pay off your balances in full every month, the interest rates on the cards don’t really matter: You won’t pay interest. But if you think that you’ll have to carry a balance, you really need to know your interest rates.

When reviewing credit card offers, consider a low-interest card from a credit union. Some offer rates around 10%.

If the rate on your card seems too high, call your issuer and ask for a lower interest rate. This could save you a lot of money while you work toward paying off the debt you’ve accrued on the card.

5. Don’t Use Balance Transfer Cards for New Purchases

If you apply for a balance transfer credit card with hopes of getting out of debt quickly, don’t use that card for new purchases. You can’t get out of debt if you keep adding to it.

6. Keep Old Credit Card Accounts Active

Do you have credit cards in the back of your wallet that you never use? Clark says that if you don’t keep your accounts active, your card issuer may decide to close them for you.

Here are two simple ways to keep your cards active:

  • Set a calendar reminder to use your card at least once every six months.
  • Make a small recurring purchase and set up automatic payments.

7. Avoid Closing Credit Card Accounts 

Clark says it’s usually not a good idea to close or cancel a credit card account. The reason? Closing a credit card account, especially one with a high credit limit, may hurt your credit score.

On the other hand, it may be worth it to close a credit card account with a high annual fee if you’re not getting the benefits.

Before you call your credit card issuer to cancel one of those cards with an annual fee, ask for a retention offer or see if you can be downgraded to a version of the card with no annual fee.

That way, you may be able to avoid the annual fee and any negative impact on your credit score.

Final Thought 

If you follow Clark’s rules and use credit cards responsibly, you’ll build a good credit score that will benefit you throughout your life.

However, Clark wants you to know that credit cards aren’t for everyone.

“Studies show that if you have a tendency to spend more money than you like, forget all rewards credit cards and just live on cash. You’ll have the greatest reward you’ll ever have: greatly reduced spending.”
