Borrowing rate for the credit union is a source of income to cover the administrative costs. All excess funds are returned to members in the form of dividends on savings. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. Credit unions are competitors of savings institutions, adding interest on deposits of members. This applies to the shares, as well as to additional funds transferred to the account in the credit union. The right to use the services of the credit union have only its members.
