As they tend to do, iSupply has broken down the iPad and worked out just what all those magical components are. After compiling and pricing all the individual parts, iSupply has
estimated that there are $259.60 in parts
in each 16GB Wi-Fi only iPad. That model retails for $499 leaving Apple with a healthy 48% gross margin.
The components associated with the display accounted for the largest proportion of the price, over 40%. The flash memory was also a big contributor to cost, but the increased price of these models keeps the margins around 50%. Clearly these numbers don't include R&D costs, but Apple has a reputation for maintaining higher margins than other hardware makers, who try to make up for lower margins with more sales over time.
We may not know just how much Apple is making on each iPad, but it seems clear they aren't taking a loss. The upcoming release of that 3G edition (with an extra $130 charge) should help as well. We look forward to the iSupply teardown of that model so we can see just what sort of magical 3G chip it has.
