Mary-Kate Olsen Net Worth

CelebrityNetWorth estimates the pair at $1 billion combined. The figure is listed jointly because most of the assets are shared businesses.

As children they signed a licensing deal that made them the face of a merchandise empire covering clothing, books and home goods, all managed through Dualstar.

The Row, founded in 2006, is a quiet luxury label with its own stores, and Elizabeth and James extended the business into a wider market.

The twins shared the role of Michelle Tanner from infancy, and by their teens they controlled a brand worth hundreds of millions in annual sales.

They stepped back from acting in the 2010s and put their time into fashion, where The Row won designer of the year awards and a following among stylists.

We publish the CelebrityNetWorth estimate dated 3 November 2026. Private label valuations are estimated from reported revenue and comparable luxury deals.
