1. Savings bank account: For savings deposits an account is opened with the bank which is called savings account. This account is opened for non-trading customers with small amounts, say Rs. 300 without cheque facility, Rs. 500 with cheque facility. The main aim of these accounts is to develop the saving habit among common people. Such an account can also be opened by two persons in joint names. The account holders are allowed to withdraw money by cheque or by withdrawal form subject to the condition that they maintain a minimum balance in their accounts. Interest is paid on minimum monthly balances and credited to the respective accounts yearly or half yearly.

Recurring deposit can be opened with small amount over a specified period. The depositor keeps on depositing a certain sum of money every month. The number of monthly installments may be 12, 24, 36, 48, 60 and so on. After the expiry of the period, the depositor gets back his money along with interest thereon. Cheques cannot be drawn to withdraw money from a recurring deposit account.
