Do credit cards make money if you pay in full?

Yes. Even if you never pay interest, the issuer typically earns a share of the interchange fee that the merchant pays on each purchase. Some cards also charge annual fees. Paying in full avoids interest charges, but it does not mean the card earns nothing for the issuer.

What is an interchange fee?

It is a fee a merchant pays when a customer uses a card, usually a small percentage of the sale plus sometimes a fixed amount. Most of it goes to the bank that issued the card, and the card network sets the rules for it.

Who pays for credit card rewards?

Rewards are largely funded by interchange fees paid by merchants, along with interest and other fees from cardholders. Because merchants may raise prices to cover costs, some argue that the cost is spread across all shoppers. How large that effect is remains debated.

Are Visa and Mastercard the banks that issue my card?

Usually not. Visa and Mastercard operate payment networks that connect merchants and banks. The bank or other company that issues your card sets your interest rate and fees and takes on the risk if you do not repay. Some companies, like American Express, do both.

How do credit cards make money?

Credit cards make money in a few main ways. The biggest are interest charged on balances that are not paid off, and interchange fees, a small cut of each purchase that the merchant pays through the payment network. Many cards also charge annual fees, late fees, and other smaller fees.

What makes it interesting is that the streams pull in different directions. Someone who pays the full balance every month never pays interest, yet still generates interchange revenue for the card issuer. Someone who carries a balance generates interest. Rewards like cash back are largely funded by those merchant fees, which is part of why the whole system hangs together, and why people debate who ends up paying for them.

An episode would walk through the path of a single purchase, from swipe to settlement, and show who takes a slice along the way. It would cover the roles of issuers, networks, and merchants, and how interest is calculated. This page was written for bre, an app whose hosts are AI and can be wrong, so treat it as a starting point and check anything you plan to rely on.

What a bre episode would cover

An outline of the episode bre would make for this question. Every episode is written fresh when you ask, so yours will differ.

What happens when you swipeFollow one purchase from the card reader to the merchant's bank, and see who handles it along the way.
Interchange: the fee merchants payMerchants receive slightly less than the sticker price, and part of that difference goes to the bank that issued your card.
Interest on balancesHow an annual percentage rate turns into daily charges, and why carrying a balance is the core of the business model.
Fees: annual, late, and othersSome cards charge for membership or for missed payments. A look at what these fees are and why they vary.
Who pays for rewards?Cash back and points are largely funded by merchant fees. We lay out the debate over whether that shifts costs onto everyone.
The role of networks and issuersVisa and Mastercard run the networks, while banks issue most cards. Some companies do both, and the split changes who earns what.
Why credit risk mattersIssuers lose money when borrowers do not repay, so lending decisions and interest rates are tied to that risk.

How the episode might open

A sample exchange between two of bre’s AI hosts, bre and Arlo. Both are AI; this is written by AI, as every bre episode is.

breAI host
Okay, start with the thing everyone wonders. A card gives you free money back on groceries. Somebody has to be paying for that. Who?
ArloAI host
Merchants. Partly.
breAI host
Partly, yes. Every time you tap, the store gets a bit less than the price on the shelf. A slice goes to the bank that issued your card. That slice is called interchange.
ArloAI host
So the shop pays. Not me.
breAI host
Directly, yes. But shops can build that cost into prices for everyone, including people paying cash. That part is genuinely debated.
ArloAI host
Who counted that? How much does it move prices?
breAI host
I don't know a number I'd trust, and I'd rather say so. Economists argue about it. What's clearer is the second income stream: interest.
ArloAI host
The balance people carry.
breAI host
Right. Pay in full and the bank mostly earns from fees on the purchase. Carry a balance and interest becomes a big part of the picture.
