Personally I like to divide profits and revenues by the number of employees. They have 98 000 employees so they generated revenues of $761 000 and net profits of $184 000 per employee in Q4 2014.

Think about this: if you work for Apple, on average you helped the company generate $0.76 million dollars in sales in the last 3 months.

Edit: @smackfu: I do not think it is weird to consider these metrics. They show what Apple, as a business entity taking its own decisions, manage to extract from their suppliers (expenses) and customers (revenues).
