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. Historically, credit unions have grown from the experience of credit cooperatives, but they took the experience of organizations of mutual aid of citizens by moving methods of social self-protection from labor and toward consumption. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. Credit unions, like today's credit unions, emerged in the 19th century in Germany as a result of crop failure and famine. The right to use the services of the credit union have only its members.
