These may be either secured or unsecured. Secured loans attract a slightly lower rate of interest than unsecured loans. Some banks offer revolving credit schemes. These normally involve loans repayable by regular monthly installments, but they differ from other loans repayable by installments in two respects.

Secondly, as his repayments reduce his indebtedness, he can "top up" his loan by borrowing more, provided that the total debt outstanding does not exceed his agreed credit limit.
