Savings accounts are accounts maintained by retail financial institutions that pay interest but cannot be used directly as money (for example, by writing a check). These accounts let customers set aside a portion of their liquid assets while earning a monetary return. For the bank, money in a savings account may not be callable immediately and therefore often does not incur a reserve requirement freeing up cash from the bank's vault to be lent out with interest.
The other major types of deposit account are transactional (checking) account, money market account, and time deposit.
