PROBLEM TO BE SOLVED: To provide a simple derivation work aid for performing a series of derivation work such as long-term fund design. SOLUTION: This device is composed of an outer cylinder member 100a and a slide member 100b, which can be relatively moved so that a working panel 100 can function as a derivation aid like a calculation scale, one or two processes or more can be carried out by the calculation scale function in series of derivation work composed of a process for deriving the required living costs after retirement, process for deriving the total amount of pension, process for determining an allowable degree of risk and an investment policy, process for calculating required funds, process for deriving a target reserve amount and process for deriving a monthly amount of reserve, and guide information for a series of derivation word is displayed on a panel surface. |
