Apple’s actually somewhat of an exception here. They actually make most of their profit from hardware, not services. In the first half of this year, Apple has made $167 billion in product sales, and $53 billion in services sales. Their cost of sales for products was $103 billion for products, and $13 billion for services. That gives $64 billion in profit from products and $40 billion in profit from services. So about 62% of Apple’s profit comes from product sales.

Teardown reports of iPhones indicate that an iPhone 15 costs $423 to make but costs $799, giving a profit margin of about 47%. This doesn’t account for shipping though, so the actual margin will be a bit lower.
