A new study shows that the K-pop industry is far less glamorous than it appears on the surface. Out of 1,182 idol groups that debuted over the past 30 years, nearly half fail to survive beyond their third year. The research, released on August 4 by Professor Kim Jung-seop of Sungshin Women’s University, who also serves as chairman of the Global K-Culture Economy Forum, paints a clear picture of an industry where only a tiny fraction of groups ever achieve real success.
The Numbers Behind K-Pop’s High-Risk Business
The study analyzed every idol group that debuted between 1996, starting with H.O.T. , and 2025. Over these three decades, an average of 39.4 new groups entered the market each year — roughly 19.8 boy groups and 19.6 girl groups annually. Yet the average lifespan of a K-pop idol group is only 4.12 years. This falls well short of South Korea’s standard seven-year exclusive contract, meaning most groups disband or stop activities before completing their initial agreements.
The research identified the fourth year as a critical turning point. Only 55.03% of groups remain active after their third anniversary. This means nearly one out of every two K-pop teams disappears before reaching that milestone.
Professor Kim explained the industry’s structure makes the early years decisive. Market performance during the first one to three years largely determines whether an agency continues investing in a group after its fourth year. As a result, many groups end their activities or effectively disband before completing their first contract.
The Reality of Financial Success
Achieving profitability remains an extreme challenge for most K-pop groups. Only 42 groups, or 3.55% of all idol groups studied, sold more than 300,000 copies of a single album — a benchmark commonly regarded as sufficient to recover production and marketing costs.
The numbers get even more striking at the top. Only 19 groups (1.61%) surpassed one million sales with a single album. The research found that just seven K-pop groups have exceeded 10 million cumulative album sales: BTS, SEVENTEEN, Stray Kids, EXO, TWICE, NCT and TOMORROW X TOGETHER (TXT). Together, they represent only 0.59% of the 1,182 groups included in the study.
Boy Groups vs. Girl Groups: A Clear Survival Gap
The study also revealed a significant difference in survival rates between boy groups and girl groups. Boy groups averaged 5.11 years of activity, while girl groups averaged just 3.13 years. This 1.98-year gap stems from differences in revenue models.
Boy groups tend to secure highly loyal female fandom-driven consumption patterns through albums and concerts. Girl groups, on the other hand, rely more on general public appeal and income from events and digital music, which may shorten their lifespan.
A Comparison to Small Businesses
Professor Kim noted that the three-year survival rate for K-pop groups (55.03%) is actually higher than the 41.5% survival rate for ordinary small and medium-sized startups after founding. However, it remains lower than the 68.1% rate recorded by government-supported startups.
“The K-pop industry is inherently high-risk, but it has often been viewed more negatively than warranted. The study suggests the need to reassess investment risks more objectively to support the development of the music industry.”
The ‘Post-BTS Era’ and What It Means
Professor Kim believes the emergence of multiple globally successful acts indicates that K-pop has entered what he calls the “Post-BTS Era”. Rather than BTS being a one-time phenomenon, he argues that the industry has proven capable of producing additional international stars.
However, he also stressed that K-pop must now shift its focus toward long-term sustainability. Despite its remarkable global growth, the industry continues to operate under a high-risk business model, where enormous investments often yield little return.
“BTS’s success is no longer an isolated case, which points to the emergence of a ‘post-BTS era,’ or the birth of several globally successful groups in the future. Now it’s time to be ready for the next three decades.”
Unless companies develop more sustainable, long-term management strategies instead of relying on short-term results, Professor Kim warned that maintaining K-pop’s global momentum over the next three decades could become increasingly difficult.

Why This Study Matters for Fans and the Industry
For K-pop fans, this research offers a sobering look behind the scenes of an industry often associated with luxury and fame. The reality is that most groups struggle to survive, and only a select few ever achieve the kind of success that makes headlines.
The study also raises important questions about how agencies train and debut new groups. With nearly 40 new teams entering the market each year, the competition is fierce. Many of these groups receive significant investment from their agencies, yet most never recover those costs.
Professor Kim has suggested several policy measures to address these challenges, including introducing long-term growth-oriented idol training systems, creating structures for re-challenge after failure, providing shared infrastructure support for small agencies, strengthening pre-debut verification to curb reckless debuts, and balancing global expansion with domestic survival foundations.
