She's just sold a 20% share of her KKW beauty company, banking an incredible $200million.
So how does Kim's latest windfall compare to sister Kylie's and the rest of their hugely successful family
Kim Kardashian: Estimated net worth - $900million
Sister act: Kim (centre) has potential to be the richest member of the Jenner/Kardashian family
The first member of the Kardashian family to find stardom was Kylie's big sister Kim, 39.
After a couple of years lurking on the sidelines of fame as Paris Hilton's friend and sometime stylist, she was catapulted into the public eye when an intimate sex tape was leaked in 2007. While Kim was by her own account 'devastated', her mother Kris Jenner saw an opportunity and took over, guiding Kim to win a $5million payout via a lawsuit against the company, and signing up the newly notorious family for their own reality show.
Last year Kim's net worth was estimated at $370million by Forbes, which put her at number 26 on the magazine's 2019 list of America's Highest-Paid Celebrities.
Yet the publication may have been a little wide of the mark as Coty Inc valued her beauty empire, KKW, at $1billion, buying 20% of the company for a huge $200m.
However, Forbes has since claimed the deal will leave majority owner Kim with a 72% stake but as her mother Kris Jenner owns 8% it has prevented her from attaining true billionaire status.
While sister Kylie sold a majority stake (51%) of her beauty company, Kylie Cosmetics to Coty in 2019, Kim is still in control of her brand as she owns 80%.
Mother-of-four Kim's money previously came from her share of the Keeping Up With The Kardashians show pay check. She had been earning $100million a year from KKW but the latest deal will give her brand further global reach.
She has also made millions from her computer game, Kim Kardashian: Hollywood.
Kim supplements this income with endorsements, recently confirming she gets offered up to $1million for a single sponsored Instagram post.
She said she turned down that particular offer because her husband Kanye West didn't like the 'fast fashion' company because 'they would knock off Yeezy all the time.'
Her rapper husband has called himself a billionaire, and according to Forbes Kanye earned $150million over the past year, putting him at number three on the magazine's World's Highest-Paid Entertainers 2019 list.
Kylie Jenner; Estimated net worth $900-950million
Like all her sisters, Kylie, 22, makes money from the family reality show, modelling gigs, and endorsements.
However this is dwarfed by her makeup company, which started out as a single batch of 15,000 $29 lip kits which she self-funded and sold online to her Instagram followers in 2015.
She sold a controlling stake of her brand CoverGirl owner Coty for $600million last year, making her officially the richest Kardashian until now.
Kylie commands a little more than sister Kim for her Instagram posts and at last count, charged $1.2 million (£960,000) for a single ad post.
This makes her the highest-paid Instagram Influencer of 2019, according to reports.
She's also been involved in lucrative advertising deals which have netted her around $18million, from companies such as Puma and Pac Sun.
When she first started out, Kylie's mother Kris brokered her seven figure deals as a model, scoring a huge deal with British retailer Topshop.

Kris Jenner; Estimated net worth - $90million
When her daughter's sex tape with ex Ray Jay hit the internet, Kris Jenner took control, negotiating so well that the reality star continues to make money from royalties today.
Indeed it is all thanks to Kris that fleeting infamy became something more. Shortly after the sex tape leaked she signed up the entire family for their eponymous reality show, which premiered that same year. KUWTK is currently in its 17th season, and she remains the executive producer.
She also operates as the family momager - a nickname she likes so much she trademarked it - taking a percentage cut of her children's earnings whenever she negotiates their deals.
While at 30million her social media presence is a fraction of her daughters, Kris also occasionally scores endorsement deals of her own, including a Fendi campaign with Kim and her daughter, North West.
According to the website CelebrityNetWorth she is worth around $90million, however if she negotiated Kylie's Coty deal, it will mean a huge payday.
Khloe Kardashian; Estimated net worth $40million
Along with the family reality show, and endorsement deals, Khloe has her own clothing line, Good America, which is sold in department stores and online.
Kourtney Kardashian; Estimated net worth $35million
The bulk of Kourtney's income comes from the family reality show, and endorsement deals. She is currently promoting her Diamond fragrance line with sisters Kim and Khloe.
The mother-of-three's net worth is estimated at $35million, according to Money.
Caitlyn Jenner; Estimated net worth $100million
Famous first as an Olympian, Caitlyn for years received a pay check for appearing on KUWTK.
Since divorcing Kris Jenner, she has left the money-spinning show, and come out as a trans woman. She paid her bills with her own spinoff chronicling her life as a trans woman, and released a tell-all autobiography.
She currently stars on the British reality show I'm A Celebrity Get Me Out Of Here for which she is being paid $648,000, according to The Sun newspaper.
Her net worth is estimated at $100million.

Kendall Jenner; Estimated net worth $30million
Like her sisters Kendall cuts a paycheck from Keeping Up With The Kardashians.
However she combines this role with life as a high fashion model.
Last year she was the world's highest-paid model for the second year in a row, according to Forbes, making $22.5million in 2018 alone. Money estimates her worth at $30million.

Rob Kardashian; Estimated net worth $10million
It will come as no surprise that Rob is the least wealthy of his siblings. Still, with an estimated net worth of $10million, the single dad is still a wealthy man.
Rob made his money by appearing on Keeping Up With The Kardashians and his short lived spinoff show. He stepped back from KUWTK last year, now making only occasional appearances for which he is thought to be paid $50,000 an episode. He also has a sock company, Arthur George.
