After the 30 years of working Charlie Conway has saved $950,000 in a 401k account for his retirement. If Charlie decides to take annual distributions to empty the account during the next 20 years, how much more would he be able to withdraw and spend each year if his 401k is a Roth 401k account as opposed to a Traditional 401k? Assume that the 401k earns 12% annual return, and Charlie is in the 25% tax bracket?
