At one of my old jobs contractors just cost what they cost. Benefits are the obvious one but there were also Corporate Costs which were calculated based on headcount - Exec salary, office space rental, laptop costs, etc all were line-items based on department headcount. The ratio ended up being 1/3 employee and 2/3 contractors so plenty of desk-sharing, "war rooms", etc.
