Banks make money from service charges and fees. These fees vary based on the products, ranging from account fees (monthly maintenance charges, minimum balance fees, overdraft fees, non-sufficient funds (NSF) charges), safe deposit box fees, and late fees. Many loan products also contain fees in addition to interest charges. Banks also earn money from interest they earn by lending out money to other clients. The funds they lend comes from customer deposits. However, the interest rate paid by the bank on the money they borrow is less than the rate charged on the money they lend. For instance, a bank may offer savings account customers an annual interest rate of 0.25%, while charging mortgage clients 5.75% in interest annually.
