Who makes what for the iPhone, and how much does it cost

As a management accountant, I’m always interested in what products cost to make. In today’s global manufacturing economy, it’s even more interesting as product components are sources from all over the world.  Time [May 16, 2011] provides a great example, the iPhone. According to the article, the total cost of the iPhone 5 is $179. Of this amount, $61 goes to Japanese suppliers, $11 to US  suppliers, $30 to Germany, $23 to South Korea, $7 to China [where the phone is assembled], and $48 goes to other unknown sources. Given that the selling price is around $500, this means that the loins share of the added value in an iPhone about, or $321, stays within the US company. I have to say I was surprised that China contributed so little to the final value.
