Non-interest income is bank and creditor income derived primarily from fees including deposit and transaction fees, insufficient funds (NSF) fees, annual fees, monthly account service charges, inactivity fees, check and deposit slip fees, and so on. Credit card issuers also charge penalty fees, including late fees and over-the-limit fees. Institutions charge fees that generate non-interest income as a way of increasing revenue and ensuring liquidity in the event of increased default rates.
