According to this MSN Money article, I should not even worry about an exact figure for what I need to retire. Instead, I should save up as much as possible as soon as I enter the workforce and continually add to that amount. Really?
Now, some of the suggestions are actually useful, such as the 15% rule and the leaning towards a Roth IRA.
A Roth has actually been on my list of things to do and I want to contribute the maximum amount allowed every year. That way when I do retire the money that I pull out is completely tax free, unlike the money pulled from a 401(k).
