Diane Keaton’s passing on October 11, 2025, has sent ripples through Hollywood and beyond. At 79, she left behind not just a legacy of unforgettable performances but also the question how much had she built her fortune over the decades? Most reports now place her net worth at around $100 million, after a long career in entertainment and savvy real estate investments.

When news organizations began posting obituaries, many included the figure “$100 million” under her name. That alone helped push that number into public awareness and shareability. But it’s more than just a catchy headline her career and business choices support that kind of valuation.

Diane Keaton earned steady revenue from her films “Annie Hall,” The Godfather, Something’s Gotta Give and more. She also expanded into directing, producing, and publishing. But where she truly stood out was in her real estate ambition. She bought, restored, and flipped architecturally notable homes in Los Angeles and elsewhere.

Notably, she acquired her Brentwood estate for $4.7 million in 2009, and later listed it for nearly $29 million. She also sold a Laguna Beach property for $12.75 million after a renovation, and turned over a Pacific Palisades home for $6.9 million.

When news of her death circulated, these financial highlights helped shape the narrative. The “net worth of $100 million” tag caught on because it fits both her fame and her investment profile. It gives readers something concrete in the face of emotional tributes.
