T. Rowe Price
It does appear I was right - there is an expense fee of .76% associated with this Retirement 2050 Fund.
So, now, there's the normal mutual fund fees and pile on that another .76%.
I guess it's nice to have one place to send your money but I don't know, that .75% could add up IMO. I don't think you need to hold a lot of mutual funds to be diversified and have to rebalance that often (once/year maybe).
I don't know. . .like I said. . .I do use a mutual fund of mutual funds for our college 529 because that time seems to fly but retirement. . .anyone should be able to rebalance 1x/year.
