DEVICE FOR CALCULATING INTEREST RATE OF DEPOSIT

摘要

PROBLEM TO BE SOLVED: To prevent a depositor from blunting a sense of appropriate fund management due to the fact that savings deposit does not have a settlement function. SOLUTION: The interest rate of a savings deposit is calculated in accordance with the deposit balance of an ordinary deposit. The interest rate which is applied to calculate interest of the savings deposit is set in accordance with the balance of the ordinary deposit, and the interest rate is made different so that the interest rate of the saving deposit may be higher according as the balance of the ordinary deposit is larger. Thus the depositor makes an effort to always keep a certain amount in his or her ordinary deposit account even after pulling-out of various charges or cash withdrawal from the ordinary deposit account so that the interest rate of the savings deposit which the depositor desires can be kept, and as the result, a sense to pay an attention to fund management is given to the depositor.
