Seoul, en.SERU.co.id – Nearly 82 percent of K-pop idol groups become inactive within a decade of debut, according to a study of 1,182 acts that entered the industry between 1996 and 2025. The average active period was just 4.12 years, well below the seven-year contract commonly used by entertainment agencies.
Professor Kim Jeong-seop of Sungshin Women’s University led the research, published in the Journal of the Korea Entertainment Industry Association. His team examined male and female idol groups that debuted from H.O.T. through 2025.
The study found that 87.99 percent of groups remained active after one year. The figure fell to 55.03 percent after three years, 36.62 percent after five years, 26.14 percent after seven years, and only 17.92 percent after 10 years.
“Market performance during the first one to three years after debut 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 initial contract,” Kim stated.
Boy Groups Show Longer Survival
Boy groups lasted longer on average than girl groups, with male acts remaining active for 5.11 years compared with 3.13 years for female acts.
The study linked the difference partly to revenue patterns. Boy groups typically build highly loyal fandoms that repeatedly spend on albums, concerts, and merchandise. Girl groups tend to rely more on public recognition, streaming income, and event appearances.
Commercial success was also rare. Only 42 groups, or 3.55 percent of the 1,182 acts studied, sold more than 300,000 copies of a single album.
Nineteen groups, or 1.61 percent, reached one million album sales, while only eight groups surpassed 10 million cumulative album sales. They are BTS, SEVENTEEN, Stray Kids, EXO, TWICE, NCT, TXT, and ENHYPEN.
K-pop Debuts Continue at High Volume
An average of 39.4 groups debuted each year across the three decades covered by the study.
Groups that debuted between 2006 and 2010 recorded the strongest survival rates. Some 72.34 percent remained active after three years, while 32.98 percent reached the 10-year mark.
The researchers linked that period to a more stable digital music market, rising fan spending, and increased investment in entertainment agencies.
The findings highlight the difficult reality of the K-pop industry: many groups debut, but only a small fraction remain active long enough to build a long-term career.
