It’s no secret that many YouTubers are making full-time livings on the platform, but just how much are the top creators making? While it’s possible to get an extremely rough estimate using viewership data and traditional ad rates, most creators aren’t relying solely on advertising revenue any more.

In their second annual list, Forbes has published the 10 highest-earning YouTube creators for the 2015-2016 year. Their figures are gross totals, not accounting for income taxes and management cuts, and are compiled based on a variety of sources: “data from Nielsen, IMDB and other sources, as well as on interviews with agents, managers, lawyers, industry insiders and the stars themselves.”

Forbes’ list provides a go-to resource for those looking to understand the largely-misunderstood world of how much internet personalities make. Advertising revenue, sponsorships, book deals, merch sales, and live appearances are just some of the many diversified revenue streams that leading creators utilize. These top 10 creators earned a combined total of over $70 million from June 2015 to June 2016, a 23% increase over the 2014-2015 period.

Roman successfully operates two channels with over 10 million subscribers each. His original channel was created in 2009, featuring street-style prank videos, while his newer vlog channel spotlights the daily life of his family. He embarked on an international tour with close friend Yousef Erakat (fouseyTUBE) earlier this year, and has a combined 4+ billion views, helping him pull in an estimated yearly $8 million.

1. PewDiePie (Felix Kjellberg): $15 million

PewDiePie (Felix Kjellberg)

Surprised? Felix’s channel is currently the #1 most subscribed YouTube channel in the world, becoming the first channel to reach 50 million subscribers in a landmark achievement last week. He also made headlines across the web when a joke he made about deleting his channel spiraled out of control.

According to Forbes, Pewds earned about $12 million in the 2014-2015 reporting period, compared to his now $15 million. The 23% year-over-year increase is likely due in part to his YouTube Red series, “Scare PewDiePie,” sales of his first book, “This Book Loves You,” and the launch of his mobile gaming app, “Tuber Simulator.”
