You have determined that you want to have $2,500,000 available in your 401(k) plan when you retire in 50 years and you have not yet begun to invest.

You think that you can earn 7.5% on your investments and can calculate how much you need to invest each year to reach your goal.

Since this is more than you want to invest each year, you think you will increase your risk tolerance and invest in securities that provide an 8.5% return instead.

What amount do you need to invest each year?
