Savings Plan Scenario Simulator

Definitely, you have heard a mantra from many asset managers that want your money: in the long term your investment in stocks or an index ETF will grow. Though for a one-time investment it is generally true (however, not always, recall NIKKEI), it is far away from truth for a savings plan. For instance, even if you run your savings plan for 30 years and assume annually 6% expected return and 20% volatility (very optimistic, indeed), your will make losses in ca. 15% of scenarios. And if your saving plan lasts "only" 10 years, the number of scenario with losses will be about 30%! Additionally, they delude you showing the mean (or expected) scenario. Mean is highly influenced by a couple of extremely good outcomes: finally, your investment cannot fall below zero but there is no upper bound, at least theoretically. That's why the average scenario often looks too optimistic. It is much better to consider the median as the measure of central tendency instead. Try to simulate your savings plan yourself! https://letyourmoneygrow.com/2017/11/08/savings-plan-scenario-simulator/
