How much money does the average Youtuber make?
It depends. YouTube CPM (Cost per Thousand) changes a lot but it averages $0.50-$1.00 per 1,000 views, this may have went lower recently due to sponsors being vigilant of advertising on inappropriate content.
I have owned multiple YouTube channels, it usually worked out $0.80 per 1,000 views. YouTube videos also support multiple advertisements per video, so if you have a video with 2 adverts and 100% view retention and get 1,000 views then you would get 2x the normal CPM.
The statistics vary for each YouTuber, some earn more per view and some earn less but YouTube Ad revenue is usually not the main income for YouTubers, it comes from product placement, merchandise and other sponsorship deals, dealing with the content creator directly rather than using YouTube's advertising platform.
How much you get paid from these external sources of revenue depends on your views, your influence and your demographic.
So yes whenever you see 1,000,000 views on YouTube, you can assume they made somewhere between $500-$1,000 in YouTube ad revenue (alone).
10 million? $5,000-$10,000
100 million? $50,000-$100,000
1 billion views - $500k-$1m
