Perhaps I should call Vanguard concerning this, but I figured those of you who already use them would be able to give me a quicker response. I'm a bit confused by Vanguard's mutual fund fees, especially the mutual funds which contain other mutual funds (such as the Target Date fund, which is what I'm looking at). The Target Date 2045 Fund charges a 0.16 fee. Some of the funds it contains charge a higher fee, some a similar fee. Is there a trickle down effect with these fees? For example, would I be paying the .16 plus the fees for all of the other funds? I'm conscious of this because I'm thinking of moving from Betterment, and want to be sure it's worth the effort.
