Sienna Miller Net Worth In 2025: Career, Earnings And Fame

Sienna Miller net worth is widely estimated at around $18 million in 2025, based on multiple entertainment and lifestyle reports. The British American actress and fashion icon has built her wealth over two decades of film roles, TV work, modeling and brand partnerships. Fresh interest in her finances has grown again after her recent red carpet appearance at The Fashion Awards 2025 in London, where she revealed she is expecting her third child.

The current net worth estimates reflect Miller’s long career across Hollywood studios, prestige TV dramas and high end fashion campaigns. Recent coverage from outlets such as Elle and The Sun notes that her fortune remains in the same range, with some reports converting it to roughly the high tens of millions in Australian dollars. These figures are estimates only, but they offer a useful snapshot of how much the 43 year old star has accumulated.

Sienna Miller net worth in 2025 and how it is estimated

Most recent public estimates place Sienna Miller net worth at about $18 million in 2025. Celebrity coverage in The Sun and Australian outlet Elle report that British tabloids and celebrity wealth trackers put her fortune at roughly $18 million in United States dollars, which they translate to around $27 million in Australian dollars. These figures blend the value of her property, investments and savings with projected earnings from ongoing work.

Miller began her career as a model, appearing in Italian Vogue and on the 2003 Pirelli calendar before moving into film. Her breakthrough came in 2004 with roles in Layer Cake and Alfie, followed by Factory Girl, The Edge of Love, Stardust and G.I. Joe: The Rise of Cobra. Those projects, plus later work in American Sniper, Foxcatcher and 21 Bridges, helped establish her as a bankable supporting and lead actress over many years.

Television has become another key part of Sienna Miller net worth. She earned strong notices for The Loudest Voice, in which she played Beth Ailes, and for the Netflix drama Anatomy of a Scandal. More recently she has been linked with high profile projects including Kevin Costner’s Horizon and the ITV phone hacking drama The Hack, keeping her in demand as prestige TV and streaming budgets continue to rise.

Real estate is a visible piece of her wealth picture. In October 2025, Architectural Digest and other outlets reported that Miller listed her long owned thatched cottage in Buckinghamshire for about $2.61 million, or £1.95 million. She bought the 16th century home in 2004 and later remodeled it into what she described as an artistic retreat, suggesting that a significant share of her net worth sits in property assets.

Brand work and fashion deals also support Sienna Miller net worth. Over the years she has fronted campaigns for labels such as Pepe Jeans, Hugo Boss fragrances and Swedish fashion chain Lindex, and she recently collaborated with Marks & Spencer on a bohemian inspired collection. These partnerships, along with regular front row and red carpet appearances, reinforce her status as a style reference and provide additional income on top of acting.

Legal settlements have played a small but notable role in her finances. In 2011, she accepted £100,000 in damages from the News of the World after the tabloid admitted hacking her phone, and she later received a further settlement from News Group Newspapers over alleged unlawful information gathering. These sums are modest compared to decades of acting and fashion income, but they underline how closely her earnings story is tied to her public battle with intrusive media.

How acting, fashion and real estate shape Sienna Miller wealth

The core of Sienna Miller net worth still comes from acting fees. As a mid career star with a long filmography, she can command solid paychecks for studio films, independent dramas and prestige TV. While exact salaries are rarely public, her consistent presence in high visibility projects suggests she has earned seven figure totals across multiple years, especially when back end bonuses, residuals and streaming payments are included.

Her fashion work amplifies that earning power. Miller became synonymous with the mid 2000s boho chic look, and even though she has since said she feels distant from that label, it helped turn her into a global style reference. Modern brand deals often pay well for that kind of enduring influence, particularly when combined with front row appearances and editorial shoots in major fashion magazines.

Property decisions are another way Sienna Miller manages and potentially grows her wealth. Holding a country cottage for more than 20 years and then listing it in a strong market suggests a long term approach to real estate rather than quick flipping. If she chooses to reinvest the proceeds into other homes or financial assets, that could help preserve or increase her net worth as she balances work in London, New York and other locations.

Her personal life has also influenced financial choices, though in more indirect ways. Miller is now a mother of two daughters and is expecting a third child with partner Oli Green, as confirmed at The Fashion Awards 2025 and in recent reports. That reality tends to shift priorities toward stability, long term planning and flexible work, which may mean more selective roles but also careful management of existing wealth.

It is important to remember that all public net worth figures are educated guesses. Taxes, agent and legal fees, charitable giving, private investments and living costs can all reduce headline numbers that fans see online. For that reason, the $18 million figure should be viewed as a rounded estimate that reflects Sienna Miller financial position in late 2025, not an exact balance sheet.

In summary, Sienna Miller net worth in 2025 is best understood as an estimated multimillion dollar fortune built from acting, fashion and long term property ownership. The $18 million range used by several outlets lines up with her two decade career, her real estate holdings and her continued demand on screen. As she enters a new chapter of motherhood and mid career roles, her wealth story appears stable and still evolving.
