Then and now - the biggest child stars from the '70s ranked by their net worths

Early fame didn't prove a healthy start for Tatum O'Neal, who had a troubled relationship with celebrity and first appeared in film at just nine years old. It's no surprise then, that her net worth is estimated at $1 million.

The following year, she won an Academy Award for her supporting role opposite her father Ryan in 1973's Paper Moon. Tatum has severely struggled with addiction and claims in her memoir that it stemmed from abuse at the hands of her father, which he has denied. 

Maureen McCormick brought The Brady Bunch's cool, confident and kind Marcia to life. The relatable sitcom remains her best-loved role, while the actress has also expanded into music with 1995 album When You Get a Little Lonely and a Broadway role.

Depression and addiction issues affected Maureen's career, which she discussed in 2008 memoir Here's the Story, but she's still a beloved star today and estimated to be worth an impressive $4 million.

At just 12 years old, Kristy McNichol got her first regular role on Apple's Way, followed by serious series success on Family.

Empty Nest cemented her fame in 1988, but Kristy decided to move away from the screen in 2001 when she took official retirement. She's enjoying the free time with her girlfriend of 30 years and an estimated $4 million net worth.

Barry Williams found '70s fame as the oldest son of The Brady Bunch and had a successful musical theatre career following the show's finale in 1974.

He starred in productions like Pippin, The Sound of Music and The Music Man, bringing his talents to The Masked Singer in 2022. It's no wonder that this multi-talented '70s star is worth an estimated $6 million!

At just 14 years old, Brooke Shields took on a leading role in 1980's Blue Lagoon. With credits in sitcom Suddenly Susan, Pretty Baby and Endless Love, she became a recognisable face at a very early age. 

Since then, Brooke has reflected on her experience with childhood fame, motherhood and life challenges, worked on TV shows like Jane the Virgin and starred with '80s icon Cary Elwes in A Castle for Christmas. With a variety of creative callings, Brooke has an impressive estimated net worth of $40 million.

Jodie Foster appeared in iconic 1976 crime noir feature Taxi Driver, working with Robert De Niro and Martin Scorsese at just 12 years old. The same year, she starred in Bugsy Malone and Freaky Friday. 

Since then, Jodie has been cast in iconic horror flick Silence of the Lambs and 2025 mystery A Private Life. She brings our ranking up into an estimated nine figures, but just misses the top spot to our next child star...

The Seventies brought megastar success for Ron Howard as he followed a run on The Andy Griffith Show with Happy Days in 1974, American Graffiti (1973) and starred in his first directed feature Grand Theft Auto in 1977. Now, he's best known as an Oscar-winning power behind the camera, with an estimated net worth of $200 million.
