Key Takeaways

  1. You may be able to enjoy low introductory interest rates and bonus rewards offers with a new credit card.

  2. A second credit card may help you earn more rewards, like cash back on eligible purchases.

  3. By getting another credit card, you increase your available credit, which may help improve your credit score if you keep your balances low.

Chances are that you know someone with a wallet full of credit cards. If you’ve been getting by with just one, you may wonder if it’s a good idea to add a new card or two to the mix.

 

Managing multiple credit cards may be risky, depending on your financial circumstances. However, a new card may open the door to new benefits or rewards. Before you apply for a second or third credit card, consider potential drawbacks and perks.

What’s the right number of credit cards to have?

There’s no specific perfect number of credit cards that works best for everyone. The right fit depends on your spending habits, credit confidence, and personal finance needs.

 

Consider how much available credit you feel comfortable managing responsibly to determine whether a mix of credit cards may benefit your long-term financial goals.

 

The best credit cards for each person may differ. For example, maybe you already have a credit card that offers travel points, but you want to earn cash back on gas. In that case, you may benefit from an additional credit card that offers rewards for purchases from gas stations. Ideally, you may want to only open a new credit card account that complements your existing accounts.

Advantages of having multiple credit cards

Depending on your financial situation, you may want multiple credit card accounts to meet different spending needs and help you earn more rewards.

You may receive introductory interest offers

Some credit card companies offer low introductory interest rates on purchases or balance transfers for a relatively short period after you open a new account.

 

If you always pay your balance in full every month, your credit card interest rate may not be an important factor to you. But a 0% introductory interest rate offer may help you manage a large purchase by breaking it down without interest charges. Or you may pay down credit card debt quicker using a balance transfer, which involves transferring the credit card balance from a higher-interest card to a new credit card with a lower interest rate. With a 0% interest balance transfer offer, you may have more breathing room to pay off your debt without worrying about interest charges during the intro period.

Before applying for a card with a balance transfer offer, consider:

  • When the introductory period ends
  • If there are any balance transfer fees
  • The interest rate for regular purchases

Multiple cards may help you earn more rewards

Another reason to get an additional credit card is to take advantage of its perks. Maybe when you applied for your first credit card, you only qualified for a basic, no-frills type of account that offered few extra benefits. If you’ve practiced responsible spending habits and avoided late payments, you may qualify for a higher limit and better rewards.

 

Before applying for a new card, consider what type of rewards credit card would benefit you most, such as a cash back rewards card, a card that offers additional rewards for specific purchases like groceries, or a travel rewards card that offers miles for every eligible transaction.

Did you know?

When you open a new credit card account, you may receive an introductory offer that allows you to earn more rewards. Discover automatically matches the rewards you’ve earned on your credit card at the end of your first year.1

You may build a stronger credit history with multiple cards

If you’re looking for ways to build a good credit history, getting an additional credit card may help.

 

As long as you keep your credit card balances low, a second card may help you improve your credit utilization ratio, the total amount of your available credit in use at one time. The lower your credit utilization, the better for your credit score.

 

Plus, if you avoid late payments, you may build a good credit score by maintaining a consistent payment history across all your accounts. You may monitor your progress by regularly checking your credit report.

You can establish relationships with other card issuers

There comes a time in many borrowers’ lives when their current credit card companies may no longer meet all their financial needs. If you want to expand your borrowing options beyond your current credit card issuer, applying for a new credit card with a new credit card issuer may help.

 

In time, a relationship with a second card issuer may provide access to new or better financial tools that your original credit card company doesn’t offer.

You can have a backup credit card

Have you ever lost a credit card, had it stolen, or accidentally broken it in half? If you lose access to your only credit card, you may have to make all your purchases with cash or a debit card until the problem gets resolved. A second credit card may be a convenient backup if your other credit card is unavailable or unusable.

How many Discover® Cards can you have?

You may have two Discover Cards at one time. And Discover credit cards let you earn rewards on every purchase, from cash back rewards to miles for travel and more.

If you’re considering a second credit card, you may fill out a pre-approval form to see what Discover offers you could be pre-approved for with no harm to your credit score.2

Disadvantages of having multiple credit cards

Multiplying your credit cards may multiply your rewards and perks. But juggling several credit card accounts may present some challenges. Before you apply for another card, consider the drawbacks.

Harder to manage spending

With multiple cards, you may find it challenging to keep track of your total spending and credit usage. You may even be tempted to overspend, especially if you have a large credit limit on one or more cards. Even with a lot of available credit, overspending may hurt your credit score by increasing your credit usage.

 

It’s also important to note the interest rate on each new credit card. If you carry multiple balances with high interest rates, it may not take long for your credit card debt to pile up.

Easier to miss a payment

Different cards may come with different monthly payment dates, which may make it trickier to pay your bills on time. Late payments often appear on your credit report and hurt your credit score. A lower credit score may impact your ability to open a new credit or loan account.

Multiple annual fees

With multiple credit card accounts, you may have to pay several annual fees. Some credit cards may waive the fee for new cardmembers, but you are required to cover the cost after the introductory period ends. If you want to use two or more credit cards, you may consider options without annual fees.

 

For example, Discover has no annual fee on any of our cards.

Best ways to manage multiple credit cards

Managing multiple credit cards responsibly may help you meet your financial goals and build a strong credit history.

Use all of your cards regularly

Some credit card issuers close your account if you don’t use a card for a certain period of time. Closing an account lowers your total available credit, which may hurt your credit score. Using your cards periodically may help you keep the accounts active.

Set payment alerts

Keep track of multiple cards and make payments on time by setting up payment notifications. You may be able to set up payment alerts or automatic payments through your online banking portal or mobile banking app.

Change your due dates

Depending on your credit card issuer, you may be able to change the date your monthly payment is due. Scheduling all your bills for the same day may help you budget and avoid missed payments.

 

You may also be able to set the due date to align with your payday. This may help you ensure you always have money to cover your bills when needed, so you don't harm your payment history and credit score.

Avoid canceling multiple cards at once

Canceling several cards at the same time may have a negative impact on your credit score, especially if you carry a balance on your remaining cards. That’s because closing an account lowers your total available credit, which may increase your credit usage.

Keep track of rewards

Check which spending categories earn high rewards rates on each card. You may maximize your rewards by choosing the best card for each transaction. If one card offers rewards for travel purchases, for example, make sure to use it when booking your plane tickets and hotel reservations.

The bottom line

If you’re ready to open a new credit card account, research and compare your options to find the best credit card for your current financial situation and lifestyle. And remember, whether you have one credit card or a wallet full of cards, good credit habits are vital.
