Discover Financial's revenues can be split in broadly two categories, Net-Interest Income and Non-Interest Income.
Net-Interest Income: Discover Financial offers credit to its customers and the interest is earned on these loans. Interest Income contributes 80% of the total revenues.
Non-Interest Income: Discover Financial processes transactions on its network and charges a discount fee on every transaction. A combination of discount fee and other commissions are incorporated in Non-Interest Income. It contributes 20% of the total revenues.
