The price of a new iPhone 14 Pro Max[1] or 12.9" iPad Pro[2] is ~45% component/part costs, on top of which there is all of Apple's R&D costs including the cost of developing iOS and integrating it with new hardware, amongst many other costs to Apple of bringing a new product to market.
I couldn't find public information for Apple or Google on the amount spent on R&D for iOS and Android, hence I'm not sure what the cost to Apple is of maintaining iOS and all the APIs that application developers can use to build their applications. There are some attempts on the Internet of people attempting to estimate iOS/Android R&D costs from LinkedIn data, open jobs data, other public records of revenue from app stores, etc but nothing much I can see being of use to generating a useful estimate.
It appears that in 2021, Apple received somewhere between USD$10-25 billion[3] (likely on the high end of this range) from app store sales (after paying developers) which for the 235 million iPhones[4], 58 million iPads[5] and 29 million macOS devices[6] sold in 2021 equates to about USD$77 per device sold. I'll just assume watches and TV app store sales don't make much of a difference so USD$77 may be slightly on the high side of an estimate.
Apple could perhaps increase the price of all their iPhone, iPad and MacBook models by USD$77 and do away with collecting revenue through the app store, but would consumers still buy these devices at the higher price points?
