Where Does the Money Come From?

Credit card companies pay for rewards with revenue from two main sources: you—the consumer—and the merchants who accept their cards.  You’re likely aware of your contribution. You pay interest whenever you carry a balance on your card and fees whenever your payment is late or you get a cash advance. But most consumers don’t know about the fees that retailers pay card issuers behind the scenes. These fees, called interchange fees, are set by credit card processing networks like Visa and MasterCard to cover both the risk and cost of processing credit card payments. There are more than 100 different interchange rates that can be applied to a credit card transaction depending on the type of business, the type of card being used, the transaction amount, and whether the card is dipped, swiped, or keyed. Interchange rates include a percentage of the transaction amount plus a flat fee. Rewards credit cards have higher interchange rates than run-of-the-mill cards because the card issuers have to recoup the cost of paying the rewards. For instance, if you used a Visa Signature Preferred rewards credit card to buy dinner out, the interchange fee would be 2.4% of your bill plus a 10-cent fee. So on a $100 tab, the restaurant would pay $2.50. If you used a non-rewards card, that rate might be 1.54% plus the 10-cent fee—or only $1.64. Interchange fees generate billions of dollars in revenue, helping to cover the expense of credit card rewards. Take American Express as an example. The company, which is both a card issuer and a network, collected $6.6 billion in fees from merchants in the second quarter of 2019—75% of all its non-interest revenue. In the same quarter, cardholder rewards cost the company $2.7 billion.

How the Cost Is Passed on to Consumers

Merchants can try to recoup the cost of accepting credit cards, but it’s not clear how often they actually do. In recent years, they’ve won the right to assess a surcharge to customers using a Visa or MasterCard credit card, although some states have banned those surcharges. In some cases, retailers may raise their prices to compensate for interchange fees, so cash buyers end up subsidizing credit card rewards programs. A 2010 study published by the Federal Reserve Bank of Boston found that the average cash buyer effectively pays $149 to card users each year. Meanwhile, the average card buyer receives $1,133 from cash users.

Avoid Paying for Your Own Rewards

Merchant interchange fees are just one form of credit card company revenue. Rewards are also funded through the interest and fees that issuers receive from cardholders. Whenever a consumer carries a credit card balance, interest in the form of a finance charge is applied to that balance. About 44 percent of cardholders carry a balance each month, according to the American Bankers Association. Discover alone collected $8.8 billion in credit card interest in 2018. If you truly want to benefit from your rewards credit card, you shouldn’t carry a balance and you shouldn’t pay any avoidable fees, particularly late fees. If you’re shopping for a new rewards card, look for one without an annual fee, unless you’re sure the rewards you’ll earn will more than offset that cost.
