The average number of credit cards people have has been declining for the past decade. In 2015, it was 4.1 active cards (either used or carried a balance in the past six months), according to Experian data. In 2025, was down to 3.7.

In part, that's because younger Americans are favoring debit cards, cash, and buy now, pay later services over traditional credit cards. A 2026 U.S. News survey found that only a quarter of millennials and Gen Zers used credit cards as their primary payment method, compared to 42% of Baby Boomers. More than 20% of Gen Z respondents said they never use a credit card.

Your credit mix, including revolving credit and installment loans, accounts for 10% of your FICO Score.

Experts suggest having at least two to three active credit cards, in addition to other forms of credit, like a mortgage, car loan or student loans.

Ultimately, however, the right number of cards depends on your financial situation. When managed properly, multiple credit cards can allow savvy consumers to earn points and enjoy benefits like travel insurance and lounge access.

If you have poor or fair credit (a FICO score below 670), however, you may have difficulty managing just one card.

As with most financial issues, how you use your credit cards informs if there's such a thing as "too many."

"For someone who is responsible about using their cards and never carries a balance, then no, there is no number of cards that's too many," credit expert John Ulzheimer told CNBC Select. "[But] if you're using your cards to supplement to your income and you're carrying balances each month, then one card may be too many."

Having ten credit cards can enable you to maximize rewards, lower your credit utilization rate and improve your credit score. But if you're not making timely payments, are carrying multiple balanes or got all the cards recently, that can hurt your score.

If you decide to open multiple credit cards, it's a good idea to consider how each card can help you save money on your spending. You can maximize benefits by selecting a mix of cards offering a range of advantages, such as bonus cash back an introductory 0% APR offer or travel rewards.

"It's definitely nice to have multiple cards if they allow you to optimize rewards points," says Priya Malani, founder of virtual financial planning firm Stash Wealth.

For example, if you want a card with increased rewards on gas and groceries, our top picks are the PenFed Platinum Rewards Visa Signature® Card, with 5X points on gas purchases at the pump, and the Blue Cash Preferred® Card from American Express, which offers 6% cash back at U.S. supermarkets on up to $6,000 per year in eligible purchases (then 1%). Cash back is received in the form of Reward Dollars that can be redeemed as a statement credit or at Amazon checkout.

The number of cards you own can positively or negatively impact your credit score.

Payment history

Payment history accounts for 30% of your FICO Score, so it's crucial to pay your credit card bills on time and in full. Having more than one card may make it easier to overspend and harder to keep track of payment dates.

"Call your credit card company and have them reset the billing cycles so that they are identical for all your cards," Malani recommends. "It's easier to remember one day than several, which means you're less likely to miss a payment."

Setting up autopay is another way to avoid having to remember multiple due dates.

Credit utilization rate

The balance you owe across all of your credit accounts as compared to your total credit limit is known as your credit utilization rate. Having multiple credit cards can give you a lower balance-to-limit ratio, Ulzheimer explains, helping your credit score.

"The primary 'con' is you can get yourself into a ton of really expensive debt if you're not responsible," he said.

If you have a total credit limit of $30,000 and your outstanding credit card balances total $9,000, your credit utilization would be 30%. That's about as high as you can go and still get approved for most cards and loans with good terms.

For some people, however, more credit is a tempting excuse to overspend, lowering your score credit score.

"Just because you have lots of credit available, doesn't mean you should use it.," Malani said.

Average length of credit history

Lenders want to know you have experience mananging credit, so te average age of you credit accounts is worth 10% of your score. Opening a new card lowers that average, which typically dings your score just a few points.

But opening a lot of new cards, or closing your oldest card, can have a bigger impact. For example, If you opened your first card in 2010 and add two more in 2025, the average length of your credit accounts decreases from 15 years to 9 years.

Number of credit inquiries

Each time you apply for a card, the issuer runs a hard credit check. Even if you're approved, the inquiry negatively affects your credit score. The more cards or loans you apply for, the more inquiries appear on your report.

In addition, multiple applications in a short period can be seen as a sign of financial problems by lenders.
