Re: Here is the problem...
For small partners the subscription money is split 2.50 to twitch and 2.49 to the partner. On larger streams this can amount to more than the 2.49 such that it may be the entire 5 bucks but in exchange those streams give up all ad money which is the trade off. While 5 is the standard cost of subscribing, partners can hike the cost and can also lock almost all of the channel behind the subscription ie chatting, vods, emotes etc.
The big games like Dota, LoL, WoW etc sell like crazy. Even have tv networks looking at introducing esports.
But games such as Minecraft easily will get you 500 plus if you're not a complete failure.
ibtimes.co.uk/what-twitch-how-do-i-make-money-it-1435874 Suggests that for a 3 minute ad every 1000 legitimate views will get you $3.
For an example:
500 viewers x 2.49 = 1245
500 viewers = 1.50
Thus $1246.50 per month and that's just subscriptions and ad revenue. Actual values are likely to be higher assuming tips, gifts, additional money streams etc are all factored in as well.
