Totally depends on the years, but probably an average of 0.3% or less if I had to guess.
For services and subscriptions, just a 2TB iCloud+ storage sub, iTunes Match, and Apple Arcade, so about 0.1% for that.
For iPhones, I keep mine for a long time, and most of the Macs I buy were used, so not full price.
Ironically, when I made less money many years ago, I spent a lot more money on Apple products than I do now.
Seems like as time goes on, there has been less reasons to upgrade to a new device than 15-20 years ago.
Now that I am thinking about it, almost all of my family's daily used Apple devices are now over 10 years old.
Over 10 years old:
2006 Mac Pro 1,1
Late 2011 17" MBP
AirPort Express
Five AirPort Extreme 6th gen basestations
Mid 2012 MBA
Late 2012 iMac
Two Late 2013 iMacs
Less than 10 years old:
2015 ATV4
iPhone 13 Mini
2020 M1 MM
iPhone SE3 2022
2022 ATV4K3
2023 M2 Pro MM
I have other Apple devices that I sometime use, but not what I would consider "daily used".
