People keep bringing up R&D and other costs, but never seem to sit down and calculate them. So early last year I did, using figures from filings and Apple trial testimony. Since it's been a year or two since I did this, the numbers are a bit out of date, but they're in the ballpark, and some of it was surprising to me:
Apple said at trial that they make an average 53% gross profit margin ($340) on iPhones. That's their raw revenue after paying for the parts, manufacturing, packaging, storage, shipping, and patent licenses per device.
Of that $340 gross per phone, about $20 goes to R&D, $50 to support Apple employees and buildings and sales and ads, and $70 is put aside for taxes... leaving a nice net profit of $200 (30% net margin) per phone.
The only other smartphone maker to meet or beat that kind of margin % was RIM in its heyday. Most others average 15-25% for smartphones, I believe.
Summary: Out of the $640 Apple sells each iPhone for, $300 goes to its production and related fees, $140 goes to corporate costs, leaving $200 or more clear profit to stick in the bank.
Again, the numbers are old, so I'd drop them all by about 5% for today's device.
