Susan Dell is best known to the public as the wife of Michael Dell, the billionaire founder and chief executive of Dell Technologies, but she has quietly built an extraordinary fortune and philanthropic legacy of her own. A fashion entrepreneur, elite endurance athlete, and co-founder of one of America's largest private foundations, Susan Dell has turned both her own talents and her family's vast wealth into a force that has reshaped education, health care, and child welfare across the United States. With a personal net worth estimated at roughly $2.5 billion, she ranks among the wealthiest women in Texas, and her influence extends far beyond any single balance sheet. In December 2025, she and her husband made headlines around the world by announcing a historic $6.25 billion charitable commitment, cementing the Dells' place among the most generous philanthropists in modern American history.
Who Is Susan Dell? The Billionaire Behind the Dell Name
Born Susan Lynn Lieberman in Dallas, Texas, Susan Dell grew up far removed from the technology industry that would one day define her family's name. She studied fashion design and early-childhood education at Arizona State University, cultivating the eye for craft and detail that would later shape her career. In 1989, she married Michael Dell, who had founded Dell Computer Corporation just five years earlier, building and selling computers from his University of Texas dorm room and rapidly turning the company into a global technology powerhouse.
Rather than retreat into the comfortable role of a tech founder's spouse, Susan Dell carved out her own professional identity. Over the years she launched three fashion labels, the most prominent of which was Phi, a luxury ready-to-wear brand she founded in 2003. The critically acclaimed line developed a devoted following in the New York fashion scene, opened a flagship boutique in SoHo, and drew praise from industry insiders. Her reputation grew so strong that she was asked to design inauguration festivity dresses for presidential daughters Jenna and Barbara Bush. In an interview, she once reflected that her passion began early: "Really, the truth is that I started designing when I was a little girl. I would always choose my dolls by what they had on."
From the Fashion Runway to Philanthropy: How Susan Dell Built Her Fortune
Susan Dell's wealth comes from a combination of sources rather than a single payday. Her fashion ventures were never the primary engine of her fortune, but they established her as a serious entrepreneur in her own right. By 2004, the Susan Dell collection was generating about $2 million in annual sales, a respectable figure in high-end fashion. Although the Phi label ultimately closed in January 2010, a casualty of the recession that swept through luxury retail, it remains one of the most recognizable chapters of her professional life.
The foundation of her net worth, however, is her marriage to Michael Dell and the fortune they have built together. Michael Dell's net worth has been estimated by Bloomberg at roughly $147 billion, making him one of the wealthiest people on the planet, while Forbes has placed the figure even higher. As his wife and partner for more than three decades, Susan Dell shares in that wealth, and independent estimates commonly place her personal net worth at approximately $2.5 billion. Beyond the financial figures, she has converted a significant portion of that wealth into a permanent giving enterprise.

Where the Money Goes: The Michael & Susan Dell Foundation

Susan Dell has served as co-founder and board chair of the foundation, and she holds a life trustee position on the Dell Children's Foundation board. Her hands-on approach to giving reflects a philosophy that wealth is a tool for impact rather than an end in itself.
The $6.25 Billion Gift That Put Susan Dell in the Headlines
In December 2025, Susan and Michael Dell appeared at the White House alongside President Donald Trump to announce a landmark charitable commitment. The Dells pledged $6.25 billion to supercharge Trump Accounts for America's Kids, a child savings and investment program. The gift is designed to provide $250 investment accounts for 25 million American children age 10 and under living in ZIP codes with median incomes below a certain threshold.
The announcement thrust Susan Dell into the national spotlight and underscored the scale of the couple's giving. At the event, she encouraged parents and grandparents to claim their children's accounts, describing the initiative as an investment in the future of American families. The commitment is among the largest philanthropic gifts tied to a single federal program in recent memory and reinforces the Dells' standing as one of America's most consequential philanthropic couples.
