Credit Card Fees: 5 Things You Should Know

The debate over interchange fees is heating up as merchants protest against them.

Each time you swipe your credit card to pay for coffee or groceries, the merchant pays about 2 percent in fees to the banks and card networks behind the plastic. And merchants aren't too happy about it. They recently accused credit card networks and issuers of unfairly overcharging them. But card companies argue that paying 2 cents on every dollar is a relatively small price to pay for the benefits that come from offering their customers the ability to pay without cash. The debate over these so-called interchange fees is heating up as lawmakers on Capitol Hill consider regulations that would restrict them.

While the details of the fees can get complicated, the basics are pretty straightforward, and they can affect how much you pay at the cash register. Merchants, including everyone from grocery stores to clothes retailers, usually pay between 1.6 to 2 percent of the purchase price each time a customer pays with a credit card. Most of that money goes to the bank that issued the card, partly to compensate it for the risk that the customer won't pay his or her credit card bill. (The store gets paid by the bank either way.) Merchants argue that those fees eat into their already thin profits, especially in the midst of a recession, and that they should be lower. The credit card contingent, meanwhile, says the fees are necessary for the card system to work as well as it does.

Where does all this leave shoppers? Here are the five things you should know about credit card interchange fees:

The fee pays for convenience. Card issuers "are providing a service, not just to cardholders but to merchants, and it's reasonable that there's a fee associated with that," says Ron Shevlin, senior analyst at Aite Group, a research and advisory firm. In other words, customers can walk into almost any store, anywhere in the world, and use plastic to fund their purchase. Retailers, in turn, are able to offer their shoppers a variety of payment options. Those perks require networks that cost money to run.

You're no t necessarily paying the feemerchants are. That's why merchants are complaining so vocally about it. According to Hank Armour, chief executive of the National Association of Convenience Stores, interchange fees are merchants' greatest expense behind payroll and are more costly than rent.

There's some debate over whether or not merchants simply pass the cost directly on to consumers. One study of what happened in Australia after the government regulated interchange fees found that it was impossible to determine whether merchants passed on price reductions to customers, partly because prices are determined by so many factors. (The study was funded by MasterCard and performed by an independent economic consulting firm.) "There is absolutely no reason to believe merchants would lower prices if interchange fees were lower," says Adam Jusko, founder of

Merchants, however, say shoppers are the ones who are ultimately paying for the interchange fees. "The average American pays $427 a year in hidden swipe fees," says Armour. If interchange fees were limited, then the savings would be passed on to consumers, he adds.

Interchange fees tend to be lower in other countries. A report recently released by merchants and retailers reports that fees in the United States are among the highest in the world—higher than the fees in Canada, Europe, and Britain. But Trish Wexler, spokeswoman for the Electronics Payment Coalition, which represents credit unions, banks, and card networks, says that comparison is misleading because while the interchange fee might be lower, the overall fee that merchants pay—known as the merchant discount fee—is average.

Fees on rewards cards tend to be higher. Card issuers fund the rewards they offer customers partially through higher interchange fees, says Shevlin. And because the use of rewards cards has grown so dramatically, interchange fees have effectively gone up, squeezing merchants' profit margins, he says. (Most merchants pay a blended rate for all cards, including rewards and nonrewards cards, according to the Electronic Payments Coalition.)
