How to use

・ Enter parameters such as “investment period,” “expected return,” and “standard deviation (risk)”.
A guide to the reference returns and standard deviations for each asset class is included.

・ Click the “Run Simulation” button.

・ This automatically generates a graph showing the investment’s progress and final projected value.


You may also remove percentile lines that are not in focus, allowing you to more clearly observe the movement of the selected percentile.

You can clearly see how the selected percentile line changes over time.


A PDF file with reference values by asset class which you can input, plus a calculation tool (compatible with Excel 2010 or later), are included.


Once you understand average return and standard deviation, you can also use this simulator for any type of investment asset.

Notes / Disclaimers

This tool calculates simulated values based on past performance periods of risk and return, and does not guarantee that actual investment results will match the simulation. In the event of unexpected price drops, economic shocks, crises, earthquakes, tsunamis, turmoil or war, real investment outcomes may deviate significantly from the simulated figures. We accept no liability whatsoever for any losses incurred by you through using this tool. Please invest based on your own responsibility and judgement.
