So are you getting a salary of $2.5m (from a company that you do not own), or are the CEO/owner? I'm guessing this is a CEO salary in any case?
I would guess:
4000 people make > $500,000 / year
1000 people make > $1,000,000 / year
250 people make > $2,000,000 / year
50 people make > $4,000,000 / year
~7 people make > $8,000,000 / year (the executive team)
This includes stock and cash and bonus. All in.
