Charlie deposits, or invests, his paycheck in a savings account. the bank can then offer some of the money to a borrower in the form of a loan. how can charlie benefit financially from this relationship?

Charlie can benefit from this relationship by having his money in a savings account and it being used to offer someone a loan because the loanee has to pay interest for the loan and some of this interest goes to pay Charlie though interest on savings accounts is usually quite low unless it is a special like a jump start savings account such as is available at some credit unions,
