Mary-Kate Olsen | Net Worth: $250 Million

Mary-Kate Olsen has earned an enormous net worth of $250 million through a wide-ranging revenue stream that includes fashion design, writing, and producing, aside from acting. At the tender age of nine months, the actress started her career along with twin sister Ashley on the television sitcom Full House and has since appeared in several television and movie projects, including Factory Girl, Weeds, and Samantha Who, among others.

Apart from acting, Olsen’s retail empire, together with Ashley, rakes in more than $100 million every year—it was great investment planning on their part. She has also co-founded several other brands, still with her twin sister, like Olsenboye, The Row, Elizabeth and James, and StyleMint. The actress also had an equestrian career, starting horseback riding in 1992 at the age of 6. She has professionally competed since then, taking part in the American Gold Cup and Longines Global Champions, to name a few. With her overflowing wealth, Olsen can do whatever she likes professionally or as a hobby.
