In the game you start with 38,000 dollars. For reference at a rate of return of 5.575% [0], this would yield on average 8.6 million after 100 years. I only mention this to give some idea of what the returns on investment are in the long term.

[0] The average return of S&P500 from 1915 to 2015 according to http://dqydj.net/sp-500-return-calculator/

EDIT: these figures are wrong because they don't include dividends. See thread below.

Why didn't you include dividends? In that case, the parameters you entered would give a RoR of 9.9970%?

Oops, you're right, I overlooked that. So it would be 520 million after 100 years (22 million after accounting for inflation).

According to this we will see 21x inflation between 1999 and 2100. Just using cpi

Just checked: the figure I gave was not inflation adjusted. In terms of real dollars, after 100 years your investment would be worth a measly $365,000.
