2016 had $90B revenues and 1.5B 30d active users (for YouTube) so $60 per year would be a good guess.
(Disclaimer: I'm a Googler but I just got these numbers from public statements. No way I'm well paid enough to be able to see more detailed numbers. :-D )
Personally I'd happily pay $5/mo for all of my google services if it meant I was entirely removed from the whole advertising/"customer-is-a-product" offering and I could have confidence that I wasn't being sold as a product in other regards.
