How much is Ko So-young Worth? Ko So-young Net Worth in 2026
Ko So-young’s net worth is estimated at $28 million as of November 2026. The building she showed off on her YouTube channel in January 2026, the one she called a dutiful son, is not hers: the Hannam-dong property is registered to her husband, actor Jang Dong-gun. Her own money sits in a Cheongdam-dong building she built from the ground up, a share of a family company’s building in Songjeong-dong, and the couple’s penthouse.

How much is Ko So-young worth in 2026?
About $28 million, by our estimate, counting only what we can tie to her. That is a choice that shrinks the figure: her husband’s Hannam property alone was put at about 30 billion won by an agent’s estimate and 20.6 billion won by a valuation platform. We convert at about 1,332 won to the dollar, the rate on X-Rates on November 12, 2026. This one is a rough estimate: little of her own money has a published price.
How we got to $28 million
| Source | Our estimate | What it rests on |
|---|---|---|
| Cheongdam-dong building | $9.0 million | Our assumption: 12 billion won. The building has two basement floors and five above ground, and she bought the land and built it new. No price or valuation has been published. |
| Half of the Songjeong-dong building | $1.5 million | Bought in February 2022 by 9Core Holdings, a family company, for 3.95 billion won (one earlier report says 3.55 billion). Our assumption: half, 1.975 billion won, is hers. Her brother runs the company and she is a director. |
| Half of the Cheongdam penthouse | $6.2 million | The couple’s home at The Penthouse Cheongdam has an official assessed price of 16.4 billion won. Our assumption: joint ownership, so 8.2 billion won. Assessed prices usually sit below market. |
| Hannam-dong building | $0 | Bought in 2011 for 12.6 billion won in Jang Dong-gun’s name. We leave it out of her figure. |
| Cash and investments from her career | $11.3 million | Our assumption: 15 billion won kept from film, drama and advertising work since the early 1990s. No fee has been published. |
| Total | $28.0 million | Our sum of the rows above: 37.2 billion won. |
The family’s best trade is in his name
Jang Dong-gun paid 12.6 billion won for the Hannam property in June 2011, borrowing about 4 billion won, Starnews reported. A Porsche Studio fills the ground floor. The previous owner had bought it about two years earlier for 8.45 billion won, The Korea Economic Daily noted in January 2026.
Our calculation: if the 30 billion won estimate holds, the building rose 17.4 billion won in 15 years, about 138%. On the valuation platform’s 20.63 billion won it rose 8 billion won, or 64%. On the higher number it equals about four fifths of everything we credit to Ko So-young herself, 37.2 billion won. Count half of it as hers and her figure would jump by $8 million to $11 million, which is why the line between spouses matters so much here.
A small building near Seongsu
The family company’s building is five floors and 352.75 square meters, near the Seongdong tax office. When the family company bought it in 2022, land in the area had roughly doubled to more than 40 million won per pyeong in a few years, as buyers spilled over from Seongsu-dong across the road, Money Today found. Singer Hong Jin-young later bought the building directly opposite for 3.5 billion won, The Asia Business Daily reported.
From The Fox with Nine Tails to Ms. Perfect
She debuted in the early 1990s and was a film lead through the decade: The Fox with Nine Tails in 1994, Beat in 1997, and A Day in 2001, which won her the Grand Bell Award for Best Actress, her filmography shows. Her most recent drama role listed is Ms. Perfect in 2017. Since then her public work has largely been her YouTube channel, where the January 2026 Hannam-dong video drew coverage across the Korean press.
Why other estimates disagree
Most public estimates fold the couple’s property into one number, including the Hannam property in her husband’s name, and some describe the penthouse at market value rather than the assessed price. Few say which buildings are counted.
What would move the figure
A published price for the Cheongdam-dong building would replace our largest assumption. A sale of the Seongdong property, or new Seongsu-area transactions, would reprice the family company’s stake.
