Kim Yu-bin Net Worth Details
As of 2026, Kim Yu-bin has an estimated net worth of $4 million. Her fortune comes from her years as a core member of Wonder Girls, solo music releases, acting work, brand endorsements, and continued engagement with South Korea’s entertainment industry.
While she is not among the wealthiest K-pop figures, her career longevity, strategic personal brand, and diversified income streams make her net worth both credible and sustainable. Industry analysts note that former JYP Entertainment group members with active solo careers typically maintain assets in this range.
Wonder Girls Career
Yubin joined Wonder Girls in 2007 and remained with the group until its disbandment in 2017. She became closely identified with the group’s rap sections and retro-pop image during one of K-pop’s most important second-generation eras.
JYP Entertainment later noted that Wonder Girls’ “Nobody” became the first K-pop single to enter the Billboard Hot 100, reaching No. 76 during the group’s U.S. promotions.
JYP’s 2020 statement on Yubin’s departure also confirmed that she had been with the agency for 13 years after joining Wonder Girls in 2007.
Solo Music Career
After Wonder Girls disbanded, Yubin continued with JYP Entertainment and prepared a solo career. Her actual solo debut came in June 2018 with the single album City Woman and title track “Lady.”
Coverage of her 2018 solo debut documented the June 5 release and Yubin’s comments about developing a musical identity outside Wonder Girls.
She later released additional solo material, including “Thank U Soooo Much” and Start of the End, continuing the retro and city-pop influences associated with her post-group work.
rrr Entertainment
After leaving JYP Entertainment in January 2020, Yubin founded rrr Entertainment. The company name stands for “real recognize real.”
Yubin announced rrr Entertainment in February 2020, describing herself as both founder and artist of the company.
That move added business ownership and artist management to her career, although the company’s revenue and Yubin’s personal compensation are not publicly disclosed.
Acting and Television Work
Yubin has also worked outside recorded music through television, variety programs, and acting. Her screen work includes the 2013 drama The Virus as well as numerous entertainment-program appearances.
Those activities broaden her career beyond album sales and performances, but public sources do not support the speculative per-episode acting fees or annual solo-income estimates that appeared in the original draft.
Relationships and Personal Life
Yubin publicly confirmed a relationship with South Korean tennis player Kwon Soon Woo in May 2023. Her agency later confirmed in October 2023 that they had ended the relationship and would remain supportive friends.

There is no reliable basis for the original draft’s claim that Yubin married a baseball player in 2017 or has a son; those statements were removed.
