And let's not sleep on this, her momager Kris Jenner no doubt is set for a hefty chunk of the change.
Kylie Jenner may be the youngest sibling of the Kardashian-Jenner clan, but she is also the family member bringing in the most cash.
In addition to bringing in millions from her families' reality shows and many more millions from product endorsement deals, Forbes estimates her booming makeup company, Kylie Cosmetics, is worth almost $800 million.
It's hard to conceptualize Jenner's exponential wealth, but Forbes highlights its direct connection to her social media success.
"Social media is an wonderful platform; I have such easy access to my fans and my customers".
As RadarOnline.com readers know, the gorgeous 21-year-old influencer has gained fame-and cash-from her wildly popular Kylie Cosmetics brand, as well as from her Instagram style and short-lived reality show.
When adding into account her product endorsements with brands including Puma shoes and PacSun clothing, the reality TV star's net worth is estimated to around $900 million.
"Before I even refreshed the page, everything was sold out", Jenner recalled.
"We consider any person who built her own fortune, and didn't inherit the money, to be self-made", Forbes' methodology reads.
"It has sold more than $630 million worth of makeup since, including an estimated $330m in 2017".
Before the company started three years ago, Kylie used some $250,000 of her earnings from modeling gigs to pay an outside company to produce the first 15,000 lip kits but quickly realized she wanted to do it on her own.
Jenner's company only has seven full-time and five part-time employees.
"Maybe one day [I'll] pass this on to Stormi, if she's into it."
