How Credit Cards Make Money (It's Not the Interest)

Marcus taps his Chase Sapphire at Target and thinks he just paid forty-three dollars for groceries. He did not. Three other parties took their cut before he reached the parking lot — and he funded someone else's first-class upgrade while doing it. The average American carries six thousand seven hundred dollars in credit card debt at twenty-two percent interest. But interest is not where the real machine runs. This video pulls apart exactly how the credit card system makes money: the one hundred and eleven billion dollars in swipe fees merchants paid in 2024 built into the price of everything you buy, the rewards flywheel that redirects eighty-six percent of interchange back to cardholders to keep them spending, why cash-paying households transfer one hundred and forty-nine dollars per year to wealthier rewards cardholders, why revolvers generate eighty-five to ninety percent of issuer revenue despite being sixty percent of accounts, how the minimum payment was engineered as a behavioral anchor — not flexibility, the Wells Fargo scandal where five hundred and sixty-five thousand credit card accounts were opened without consent from 2002 to 2016 resulting in a three billion dollar federal settlement, the Visa and Mastercard thirty-eight billion dollar antitrust settlement over swipe fees, and how Mastercard runs twenty-five data products selling your transaction history to advertisers and hedge funds. The credit card is not betting you will pay your bill. It is betting you will not.
