does vanguard grant admiral shares only on a per-account basis?
user
yes, each of vanguard's mutual funds looks only at its own shares when deciding to upgrade/downgrade the shares to/from admiral status. to the best of my knowledge, if you hold a fund in an ira as well as a separate investment,  the shares are not totaled in deciding whether or not the shares are accorded admiral shares status; each account is considered separately.  also, for many funds, the minimum investment value is not $10k but is much larger (used to be $100k a long time ago, but recently the rules have been relaxed somewhat).
