You and your wife each contrubute $500 a month into a 401K retirement account beginning today. you only make these contrubutions for a period of 10 years, each year increasing the contrubution by 3%. if you are 25 now how much will your account be worth when you retire at age 65? the rate of return expected is 7%.. B- from the problem above, you are now 65 and retierd. if the total amount from your 401k savings ( computed above) were invested at an interest rate to keep up with inflation , say 4% and you figured you'd live 35 years in retirement, what annual income would your 401k savings provide you.
