Most people know Sienna Miller from the tabloids. Few know the full story of how she actually built her money.
Sienna Miller’s net worth in 2025 is estimated at $18 million. That figure comes from over two decades of acting, a string of lucrative modeling contracts, co-founding a fashion label, and smart real estate moves across two continents. She didn’t just ride on fame — she worked across multiple industries to get there.
In this article, we break down every income stream, career milestone, and financial decision that shaped her wealth. We’ve also covered what the competitor articles miss, including her recent Netflix work, the tax controversy, and her real estate portfolio in full.

Early Life: New York Born, London Raised
Sienna was born in New York City in December 1981. Her family moved to London just 18 months later. Her mother is a South African former model. Her father is an American banker and art dealer. That mix of creative and commercial backgrounds likely shaped how she approached her own career.
She grew up in Parsons Green after her parents divorced in 1987. She attended boarding schools and, by her own admission, wasn’t exactly a model student. She smoked, drank, and was labelled a “rebel” by teachers. That said, she excelled at lacrosse.
After finishing secondary school, she didn’t go straight to university. Instead, she took a modeling job in Germany, saved her earnings, and used that money to fly to New York and enroll at the Lee Strasberg Theatre and Film Institute. That decision — funding her own acting training through modeling — set the pattern for the rest of her career.
Modeling Career: Where It All Started
Sienna’s first income came from modeling, not acting. She worked with Coca-Cola early on and then started appearing in high-profile publications.
Her modeling credits include:
- Vogue (Italian edition)
- Nylon
- Marie Claire
- Porter Edit
- 2003 Pirelli Calendar (one of the most coveted modeling gigs in the industry)
The Pirelli Calendar appearance got her noticed internationally. It’s unpaid in terms of fees, but the exposure is worth more than most paid campaigns. Brands came calling after that.
Her major modeling contracts over the years included:
- Pepe Jeans London (2006–2008) — a two-year ambassadorship deal
- Hugo Boss (2009) — announced as the face of a new fragrance
- Lindex (2016) — a Swedish fashion chain partnership
- Gucci (2020) — a photoshoot that kept her name in fashion circles
These deals don’t have confirmed public figures attached, but brand ambassador contracts at this level typically range from £500,000 to £2 million per agreement. Over a 15-year run of consistent brand work, modeling alone likely added several million to her net worth.
Acting Career Earnings: From Layer Cake to Netflix
The Early Years (2001–2008)
Sienna’s first credited acting role came in 2001 with the film South Kensington. She also appeared in TV shows like The American Embassy and Keen Eddie during this period.
The career shift happened in 2004, partly because of her high-profile relationship with Jude Law. The attention boosted her profile, and roles came more easily. That year she appeared in both Layer Cake and Alfie — two critically respected British films.
Other notable films from this period:
- Casanova (2005)
- Factory Girl (2006) — she played Edie Sedgwick opposite Guy Pearce
- The Mysteries of Pittsburgh (2008)
- The Edge of Love (2008)
Factory Girl was probably her most critically discussed role of this era. Playing Edie Sedgwick is no small thing — it’s a demanding role that earned her real respect from casting directors.
The G.I. Joe Years and Hiatus (2009–2011)
In 2009, she appeared in G.I. Joe: The Rise of Cobra — a big-budget action film that gave her mainstream commercial exposure. Franchise films like this typically pay lead and supporting actors between $1 million and $5 million depending on their role size. Her exact fee hasn’t been confirmed publicly.
After G.I. Joe, she stepped back from film. She was open about feeling burned out by the media circus. Instead, she took on a lead role in the Broadway play After Miss Julie — a serious stage production that showed she wasn’t chasing fame, she was chasing craft.
The Critical Comeback (2012–2019)
This is the period where her acting earnings likely grew significantly. She returned to film with more complex roles:
- Foxcatcher (2014) — alongside Steve Carell and Channing Tatum
- American Sniper (2014) — directed by Clint Eastwood, starring Bradley Cooper. This film grossed over $547 million worldwide. Her role as Taya Kyle, the wife of Chris Kyle, was significant screen time alongside one of the biggest box office stars working today. A supporting role in a film of this scale typically commands between $1 million and $3 million.
- Mississippi Grind (2015)
- High-Rise (2015)
- The Loudest Voice (2019) — a Showtime miniseries where she played Gretchen Carlson. This earned her a Golden Globe nomination for Best Actress in a Miniseries or Television Film. Streaming and premium cable deals for lead roles at this level often pay $150,000 to $500,000 per episode.
Recent Work: Anatomy of a Scandal and Beyond (2022–2025)
This is the gap the competitor article completely ignores.
In 2022, Sienna starred in Anatomy of a Scandal on Netflix. The six-part series — produced by Netflix and directed partly by S.J. Clarkson — brought her back to mainstream global attention. Netflix original series deals for talent of her profile typically range from $500,000 to $1.5 million for the full run.
This role reintroduced her to a generation of viewers who hadn’t followed her earlier work. It also strengthened her hand for future casting conversations.
Fashion: The Twenty8Twelve Story
In addition to modeling for other brands, Sienna co-founded her own fashion label with her sister Savannah Miller. The brand was called Twenty8Twelve — named after Sienna’s December 28 birthday.
The label launched in 2007 and was stocked in high-end retailers including Harvey Nichols. It was positioned as bohemian, accessible luxury — very much in line with Sienna’s personal style at the time. The brand ran for several years before quietly winding down.
It’s worth noting that Savannah Miller has continued independently as a fashion designer with her own label and a strong reputation in British bridal and occasion wear. The sisters’ shared fashion instincts were clearly genuine, not just a celebrity vanity project.
For Sienna, the fashion label added both income and brand credibility during a period when her tabloid coverage was otherwise overwhelming her professional identity.
The Phone Hacking Settlement: £100,000 in Damages
This is a meaningful but often underexplained entry in Sienna Miller’s financial story.
In 2011, the News of the World phone-hacking scandal broke wide open. It was revealed that journalists had illegally accessed voicemails belonging to celebrities, politicians, and crime victims. Sienna Miller was among those targeted.
She was awarded £100,000 in damages — one of the larger individual settlements from the scandal. She also gave evidence at the Leveson Inquiry, the public inquiry into media ethics that followed. She described being followed and intimidated by photographers in graphic detail.
This wasn’t just a legal win. Her testimony helped shape the public conversation around press intrusion and put her on record as one of the most credible voices against tabloid overreach in Britain.
Real Estate Portfolio: Property Across Three Countries
Sienna’s real estate decisions tell an interesting story. She’s owned property in England and the United States, with mixed results.
Gloucestershire, England — Country Retreat
In 2009, she purchased a country home in Gloucestershire. The property sits close to her sister Savannah’s residence. No confirmed sale price is publicly available, but rural Gloucestershire properties in that range typically sit between £500,000 and £1.5 million depending on size and acreage.
London — A Slow-Moving Sale
This is where things get financially interesting.
- She purchased a London home in 2011 for £2.7 million
- She listed it for sale in 2014 at £3 million
- By 2018, it still hadn’t sold — she dropped the price to £2.75 million
- She simultaneously offered it for rent at £2,000 per month
Even at £2.75 million, she would have barely broken even after seven years of ownership. London’s prime property market did appreciate significantly during this period overall, so this outcome suggests the property either had specific issues or was priced incorrectly from the start.
The rental income of £2,000 per month (£24,000 per year) is modest income for a property of that value, but it kept cash flowing.
Hamptons, New York — The $11.25 Million Weekend Home
In 2019, her Sag Harbor property in the Hamptons was listed for $11.25 million. The details:
- 6,760 square feet of interior living space
- Italian cabinetry and marble finishes
- Multiple outdoor decks and terraces
- An infinity pool with spa
- A guest cabana
Whether she sold it at asking price, below, or still holds it hasn’t been confirmed publicly. But if the sale went through at or near asking, the Hamptons property alone would represent one of her most significant financial assets.
The Tax Avoidance Controversy
One story that gets glossed over in most coverage: Sienna Miller and Jude Law were among hundreds of celebrities caught up in a £640 million tax avoidance scheme crackdown reported by HMRC. The scheme involved investing in loss-making film projects to offset tax liabilities — a structure used widely in the entertainment industry before HMRC closed the loophole.
It’s not a criminal matter. But it does add context to how celebrity wealth is managed and why net worth figures for actors are almost always estimates rather than confirmed numbers.
Personal Life: Relationships That Made Headlines
Jude Law — The Relationship That Defined a Decade of Coverage
Sienna and Jude Law got together in 2004 and got engaged that same year. In 2005, Law publicly admitted to having an affair with his children’s nanny. The couple split.
They tried again in 2009. They split again in 2011. The relationship generated years of tabloid coverage that, fairly or not, often overshadowed her professional work during that period.
Tom Sturridge and Daughter Marlowe
Sienna dated British actor Tom Sturridge and the two had a daughter, Marlowe, born in 2012. They separated but have maintained a co-parenting relationship. Marlowe is now in her early teens.
Oli Green (2019–Present)
Since 2019, Sienna has been in a relationship with Oli Green, a model roughly 12 years her junior. The couple welcomed a daughter together in 2023. This chapter of her personal life has been notably quieter than earlier years — no tabloid scandals, no high-profile drama.
Sienna Miller vs. British Actress Peers: How Does She Compare?
It’s useful to put the $18 million figure in context with her British contemporaries:
| Actress | Estimated Net Worth |
|---|---|
| Keira Knightley | ~$60 million |
| Emily Blunt | ~$80 million |
| Kate Winslet | ~$65 million |
| Sienna Miller | ~$18 million |
| Thandiwe Newton | ~$10 million |
Sienna sits in the mid-tier of British actresses her age. Her net worth is lower than Knightley or Blunt, which reflects fewer franchise roles and more time spent on prestige dramas and independent films. That’s a conscious career choice rather than a lack of opportunity — she’s turned down commercial work before.
Where Does Sienna Miller’s Money Actually Come From?
Breaking it down by income stream:
- Film acting fees — the largest single contributor, especially post-2014
- Television and streaming deals — growing in importance since The Loudest Voice and Anatomy of a Scandal
- Modeling contracts — consistent income across 20+ years
- Fashion label (Twenty8Twelve) — active revenue stream from 2007 until its wind-down
- Real estate — mixed returns; the Hamptons property likely her strongest asset
- Legal settlement — the £100,000 phone hacking payout added a lump sum in 2011
