PROBLEM TO BE SOLVED: To provide a user interface which facilitates the operation of calculating the balance of savings or the like as much as possible, and is usable when a user designs a life style. SOLUTION: On a display screen 301 operated by the user, at least one event icon 306 to be the element of an arithmetic operation and an event installation part 307 specifying at least one-dimensional value by arranging the event icon by the operation are displayed. When the event icon is dragged and dropped by the operation at the event installation part, a prescribed arithmetic operation is performed on the basis of the position and the result display of a saving amount or the like is performed on the basis of the arithmetic result.
