There are lots of other ways credit card companies can make money: - Higher interchange fees when you purchase something outside of the EEA - Currency conversion when you buy something not in EUR - High interest payments when you do not pay off your balance in full on time

On average, it will also not be a 60 day interest free loan: the "average" transaction will happen in the middle of the billing cycle, so that gives you 15 days until the invoice is sent, and many people I know pay their invoices much earlier than after the 30 days payment term.
