Kathy Hilton is a name that rings through the worlds of Hollywood, high society, fashion, and reality television. Known to some as the elegant matriarch of the Hilton dynasty, and to others as the lovable and quirky fan-favorite of The Real Housewives of Beverly Hills, Kathy Hilton is much more than a background figure in pop culture she is an accomplished entrepreneur, former actress, media personality, and socialite in her own right.
As of 2025, Kathy Hilton’s estimated net worth is approximately $350 million, when combined with her husband Rick Hilton. The Hilton name might be synonymous with hotel wealth, but Kathy has carefully crafted her own career and brand over several decades transforming her public persona into a profitable lifestyle empire.
Let’s take a closer look at how Kathy Hilton built her fortune, the sources behind her multimillion-dollar income, and why her net worth continues to rise.
Early Life: Humble Beginnings to Hollywood Circles
Born Kathleen Elizabeth Avanzino on March 13, 1959, Kathy was raised in Los Angeles, California. Her parents divorced when she was young, and her mother later married Kenneth Richards making Kathy the half-sister of Kim and Kyle Richards, who would also go on to star in The Real Housewives of Beverly Hills.
Kathy attended a private high school in Los Angeles, where she met a fellow student who would later become her husband Richard “Rick” Hilton, the grandson of Conrad Hilton, founder of Hilton Hotels.
Before she was married or known as a Hilton, Kathy dabbled in the entertainment world, landing minor acting roles in TV shows like:
- Bewitched
- The Rockford Files
- Nanny and the Professor
- Happy Days
Marriage to Rick Hilton: Entering the Hilton Dynasty
In 1979, Kathy married Rick Hilton, a descendant of the Hilton hotel fortune and a real estate businessman in his own right. Rick later co-founded Hilton & Hyland, one of the most exclusive and successful real estate brokerages in Beverly Hills. Through Rick’s career, the Hiltons invested heavily in luxury real estate, which remains a core part of their wealth today.
While the Hilton fortune was a factor in Kathy’s financial rise, she didn’t rest on her laurels. Instead, she built her own career and brand distinct from the Hilton hotel name.
Fashion & Business: Kathy Hilton as an Entrepreneur
1. The Kathy Hilton Collection
Kathy’s foray into fashion is perhaps her most successful independent business move. The Kathy Hilton Collection, launched in 2012, is a line of elegant party and evening dresses sold in high-end department stores like:
- Neiman Marcus
- Saks Fifth Avenue
- Nordstrom
- Bloomingdale’s
The designs are known for their glamour and appeal to upscale clients and red carpet regulars. Celebrities and socialites alike have worn her pieces, which retail from a few hundred to several thousand dollars per gown.
2. Retail and QVC Ventures
Prior to the dress collection, Kathy ran a gift and novelty shop and also launched products on home shopping networks such as QVC and HSN. She once sold a skincare line and fragrance called “My Secret,” which brought in millions in combined sales.
These ventures, though not her primary income today, helped Kathy sharpen her entrepreneurial instincts and added to her wealth in the 1990s and 2000s.
Reality TV & Media Earnings
1. The Real Housewives of Beverly Hills (RHOBH)
Kathy joined RHOBH as a recurring cast member (“friend of the Housewives”) in season 11, and her whimsical behavior, quick wit, and offbeat charm quickly made her a fan favorite. She reportedly earned:
- $150,000–$300,000 per season during her time on RHOBH.
Even after her exit as a regular cast member, Kathy continued to make guest appearances and maintained strong fan support, keeping her personal brand alive and profitable.
2. Other Media Appearances
Kathy has also appeared in various reality and talk shows, including:
- I Want to Be a Hilton (hosted and produced)
- Paris in Love (alongside daughter Paris Hilton)
- The World According to Paris
- Keeping Up with the Kardashians (as a guest)
Her TV appearances not only added to her earnings but also increased the visibility of her brand and ventures.
Real Estate: The Hiltons’ Lavish Portfolio
Real estate is where the Hilton family’s money has quietly multiplied over the decades. Rick Hilton’s firm has handled luxury estates for celebrities, billionaires, and royalty.
The Hiltons own or have owned several prestigious properties, including:
- A Bel-Air mansion they listed for $55 million in 2021 (later sold for ~$25 million).
- A Manhattan apartment at the iconic Pierre Hotel.
- A sprawling Hamptons estate, which they rent for up to $400,000 per season.
Their real estate holdings are estimated to be worth at least $90 million, and this figure plays a major role in Kathy’s net worth.
Philanthropy & Public Influence
Kathy is involved with numerous charities and philanthropic organizations. She has supported:
- Make-A-Wish Foundation
- The Starlight Children’s Foundation
- Race to Erase MS
- God’s Love We Deliver
