Does Vanguard have fees beyond the percentage shown on the individual fund's page?
If you only own the Vanguard mutual funds and that is it.... most likely. There is a $20 fee if you have a smaller dollar amount and you have physical statements. Again you probably don't have this fee.
If you trade non-Vanguard brokerage items(stocks, non-VG mutual funds, individual bonds, etc.) there are fees for that.
If you use their advisory service there is an extra fee for that, but only if you use it.
If you have the Vanguard total stock index admiral shares and that is it... your ER is probably 0.05% and that is it.
