There are three groups that make up credit card companies: the card issuers, the card network and the card processors.

Understanding How Credit Card Companies Generate Profits

When a bank and credit union cardholder pays interest on their purchases, or annual and late fees, they are directly contributing to how these issuers make a profit. Banks and credit unions also make money from merchants who accept debit or credit cards, by charging merchant processing fees on their card-based sales. The breakdown below helps illustrate how credit card companies make a profit from customers and merchants.


Types of Credit Card Companies

Credit card companies is a broad term for three groups: card issuers, credit card networks and credit card processors. The way these groups make money varies, as they all play a different role in credit card processing.

Credit Card Issuers

Card issuers consist of banks and credit unions, who approve credit accounts and issue cards to consumers or business owners. This group makes money from credit cards by charging cardholders fees, such as annual, cash advance, interest and late.

Note that interest fees, or your annual percentage rate (APR), can get pretty high. The Federal Reserve found that the average annual APR for credit cards in the first quarter of 2021 was 15.91%. This means that if you had a balance of $1,000, you would be charged $159.10 in interest.

Credit Card Networks

A credit card network — Visa, Mastercard, Discover and American Express — enables merchants and issuers to conduct transactions by facilitating each purchase. In essence, it serves as a middleman.

Card networks, also known as card associations, make money through the fees charged each time the card is swiped. This fee covers fund transfers from each bank, providing data to the merchant and more. The more transactions there are, the more money they make.

Credit Card Processors

Card issuers and merchant banks typically don’t communicate directly with each other — they do so through credit card processors. They work in the background to ensure each transaction is processed securely and lets the card network know about it. Similar to networks, credit card processors make money from a percentage of each transaction made between a cardholder and a merchant.

3 Sources of Income for Credit Card Companies

Consumers and merchants contribute the most to a credit card company’s profit, but this eventually gets split between the different parties involved. Learn more about how a credit card company can make money below.

Ways to Earn Profit
Description

Interest

If you have a balance on your credit card, issuers will charge interest on your account. The interest rate is established at the beginning of your agreement.

Credit Card Fees

Beyond interest, credit card issuers can also charge different fees, such as annual fees or late fees.

Transaction Fees

Card issuers, networks and processors all include transaction fees that get charged to the merchant.

6 Ways Issuers Benefit From Cardholders

As a consumer, knowing how credit card issuers profit from your purchases is important and can help you minimize or avoid these fees altogether. There are several ways that credit card companies make money from cardholders and are detailed below.

  1. 1
    Interest

    Credit card balances are charged interest in exchange for the privilege of borrowing funds. The cardholder pays the interest as part of their monthly balance to the card issuer.

  2. 2
    Annual Fee

    Some credit cards, such as travel and rewards cards, require an annual fee. This can range anywhere from $50 to up to $500, depending on the perks the card offers.

  3. 3
    Late Fee

    If you pay your credit card bill late, card issuers can charge a late fee that they profit from. It can also be accompanied by a higher interest rate and varies based on the provider.

  4. 4
    Cash Advance Fee

    Card issuers can offer the opportunity to get cash at an ATM, but they often charge a high fee. This is a preventive measure to discourage consumers from continuously withdrawing cash.

  5. 5
    Balance Transfer Fee

    A balance transfer fee is charged when you transfer debt from one credit card to another, which can be a good strategy for achieving a lower interest rate. To charge you for this convenience, card issuers can require a balance transfer fee.

  6. 6
    Foreign Transaction Fee

    If you make a purchase outside of the U.S., credit card issuers can charge you a foreign transaction fee to deal with hassles of communicating with foreign banks.

3 Ways Merchants Contribute to Earnings

Credit card companies also make money from merchants. For every transaction, merchants are charged different fees for accepting debit or credit card payments. While the fee itself may be minimal in the transaction, these get split between the issuer, the card network and the processor.

  1. 1
    Interchange Fee

    Every time you use your credit card, your issuer charges the merchant an interchange fee. These are charged as a percentage of the transaction.

  2. 2
    Assessment Fee

    To cover the cost of maintaining their networks, card networks charge merchants a flat-rate assessment fee on every transaction.

  3. 3
    Processor Fee

    Credit card processors also charge merchants different fees, such as flat, incidental and transaction fees.

How do credit card companies, like banks or networks, make money?

President and Founder at Upward Personal Finance

Credit card companies/banks and networks make money on both sides of the credit card processing coin. They make money from the company who accepts your credit card and they make money from you — that is, if you don't know how to play the game. The merchant, or company/storefront that accepts cards pays a merchant service fee, between 1-4% of every transaction.

This means if you bought a $100 item from a store, they may only collect $96-$99. If you only pay the minimum payment or less than the full amount of your monthly credit card bill, you will be charged interest by the credit card company on the remaining balance until you pay it in full. With average credit card interest rates hovering at around 16%, they are happy when you don't pay your full outstanding balance. Many credit card companies also charge the cardholder an annual fee for the privilege of having the card or earning rewards/benefits.

Credit cards generate revenue in three key ways:

  1. Interest from the monthly credit card balance.
  2. Interchange income, which is a fee that the merchant pays to accept credit cards instead of cash or checks. For a credit card, this is usually about 1.75% to 2% of the transaction amount.
  3. Fees, such as late fees, annual fees and foreign transaction fees.

Credit card companies make money in a few ways. They charge merchants for each transaction, typically around 2.9%. They also charge consumers for using the cards. This could be in the form of an annual fee, a balance transfer fee, a cash advance fee and late fees. They also earn interest on the money that consumers charge on their accounts, if they haven't paid off the full statement balance each month.
