Is 401k as good as it sounds given the way it is taxed?
If you put it in a normal account it is (1) taxed as ordinary income now and then (2) any growth is taxed again at the capital gains rate.  Additionally, (3) any dividends will be taxed each year.  If you put it in a 401(k), you will only be taxed once, at the ordinary income rate.   Mathematically, if you start with X and have a regular tax rate of t and capital gains rate of g and your investments return r and there are n years to retirement, then your total wealth if you put it in a mutual fund (ignoring annual taxes on dividends) will be While if you used a 401(k) it would simply be The whole g term (along with any annual taxes on dividends) is gone in the second case and that's potentially a lot of taxes.  The 401(k) is much better in terms of total wealth unless tax rates dramatically rise between now and when you retire so that the t in the second case is much higher than in the first. This is virtually never the case for people retiring now.  Of course, what tax rates the future holds, we do not know.
