TikTok's highest-earning stars Charli and Dixie D'Amelio raked in $38 million in 2021

It clearly pays to be the sister of the world's biggest TikTok star.

Charli D'Amelio, who has the most-followed account on the short-form video app, earned a cool $24 million in 2021, making her the highest-paid TikToker of the year, according to estimates by Forbes magazine. Her older sister, Dixie, came in at the No. 2 spot for 2021, with an estimated income of $14 million.

Since Charli posted her first video in May 2019, the 17-year-old has amassed nearly 133 million followers on TikTok to date. Dixie, who is 20, currently is the ninth most-followed TikToker, with 56.6 million followers.

The D'Amelios have also secured deals off-TikTok. They're featured in Snapchat's "Charli vs. Dixie," a head-to-head competition show from Will Smith and Jada Pinkett Smith's Westbrook Media. The sisters and their parents, who originally hailed from Connecticut before moving to LA, also are featured in Hulu's The D'Amelio Show, a reality series that bowed last September. Both are repped by UTA.

As TikTok has grown to over 1 billion users worldwide, the going rates that influencers can charge for sponsored content on the platform have boomed. TikTok stars can now charge as much as $500,000 for a single post, with most earning an average of $100,000 to $250,000 per post, according to Forbes estimates — more than doubling in the past two years.
