Its NOT that easy to define revenue model for Financial Sectors and Banks. There are 5 Main streams for Financial sectors. Its also applicable to Banks
Interchange is the portion of spend that the card issuer gets after cardholders use the cards to spend.
Interest paid on balances is perhaps the most obvious revenue stream in banking: simply park funds in a bank and let it pay you at the end of the month.
Just like banks, Financial Companies also, can get revenues from payment fees. Building a banking experience means offering payments in the form of ACH, wire, checks and bill pay.
Financing means giving your customers funds today and expecting them to pay them back in the future, potentially with an added fee or interest.
Software revenues are the last (and often most overlooked) type of revenue associated with financial features. As the features become an important pillar in your software, you may choose to offer them at an extra cost.
