Study: K-pop idol groups face short careers, with 82 per cent disbanding in a decade

A new study published in the Journal of Korea Entertainment Industry Association has revealed that only a tiny fraction of K-pop idol groups achieve commercial success. According to the research by Kim Jeong‑seop of Sungshin Women's University, only 8.21 percent of idol groups sold 100,000 copies of an album, while just 3.55 percent crossed the 300,000-copy mark considered a break-even point.

Only 1.61 percent reached the coveted million‑seller milestone. At the very top, a mere 0.68 percent of groups have exceeded 10 million cumulative album sales, with BTS, Seventeen, Stray Kids, EXO, TWICE, NCT, Tomorrow X Together, and ENHYPEN leading the pack. The study also highlights a concerning attrition rate, with idol groups remaining active for an average of only 4.12 years, well below the standard seven-year contract.

By year ten, only 18 percent of groups still exist. The survival rates are slightly higher for boy groups at 5.11 years compared to 3.13 years for girl groups. This discrepancy is attributed to stronger repeat purchasing patterns among boy groups' fandoms, while girl groups tend to rely more on general public recognition, streaming, and event bookings.

The report suggests that earlier debut timing offers a survival advantage, as groups launched between 2006 and 2010 thrived due to a stable digital music market and rising fan spending before the competition intensified in the 2010s. The researchers recommend structural reforms to support smaller agencies, such as long-term development systems, shared facilities, and re-entry pathways for acts that fail to gain traction early.
