Influencer Marketing Hub has created a free online tool that can give you an estimation of the media value of any Twitch channel and the potential cost of buying a sponsorship for that specific channel. It takes into account a number of factors that include the number of total subscribers, number of total video views, average media value and total estimated media value. While it’s not an official Twitch tool or associated or endorsed by Twitch, streamers and brands will find it useful.
