Instead, the cost is governed mostly by account balance. Similar to cards, PayPal accounts also have different tiers, such as Premier or Business, but these don’t affect the price, Comparitech said. With 5.75 cents per dollar, Visa rounds off the top three, followed by American Express (5.13 cents per dollar). Of all the different types of cards, MasterCard accounts seem to be the most expensive, costing 6.47 cents per dollar of credit limit, followed by Discover with 6.27 cents per dollar.
