I... Don't really see what your numbers could look like, here.
Buying a cheap Android phone is $200-300 and selling an iPhone will more than pay for that. Switching from iCloud to something else for backups will actually save a little bit per month.
Average London rent is equivalent to 40K USD per year, as a random "richer country" example. It's not in the same ballpark, is it?
Not per person, I haven't ever been charged per person except in student accommodation and Japanese hotel rooms, not sure how we'd know what that would be.
