Liliana Mumy net worth is estimated at $4 million as of 2026. The American actress and voice actress built her wealth through a career that started at age five, spanning live-action films like Cheaper by the Dozen, animated series like The Loud House, and consistent voice work across two decades of Hollywood productions.
You probably remember her face from the Cheaper by the Dozen films. But if you have kids who watch Nickelodeon, you definitely know her voice. Liliana Mumy is one of Hollywood’s quietest success stories, and her Liliana Mumy net worth of approximately $4 million proves you do not need tabloid headlines to build real wealth in the entertainment industry. She started working before she could read a full script, and she has never really stopped.
What makes her story different from most child actors is the pivot. Many young stars fade when they age out of cute-kid roles. Mumy saw it coming and moved behind the microphone. That shift from live-action performer to sought-after voice actress kept her income steady and her career growing long after her teenage years. Today, at 32, she is still booking work and still relevant in an industry that chews up and discards people twice her experience.
This article covers how Mumy built her net worth, where her money comes from, how her earnings compare to peers, and what her financial picture looks like going forward.
Who Is Liliana Mumy?
Liliana Berry Davis Mumy was born on April 16, 1994, in San Marcos, California. She comes from entertainment royalty, at least within cult classic circles. Her father is Bill Mumy, the actor best known for playing Will Robinson in Lost in Space and Anthony Fremont in the Twilight Zone episode “It’s a Good Life.” Growing up with a father who understood Hollywood gave Liliana a head start that most aspiring actors never get.
She made her film debut at age five in My Neighbors the Yamadas (1999), a Studio Ghibli production. From there, the work kept coming. She landed a recurring role as Rachael on My Wife and Kids (2002–2004) and quickly became a familiar face in family-friendly projects.
She attended Laurel Hall School and later Campbell Hall School before graduating from Notre Dame High School, showing that she balanced academics alongside an active professional career throughout childhood.
How Liliana Mumy Built Her $4 Million Net Worth
Live-Action Films: The Early Money
The biggest early paychecks came from two major film franchises. Mumy played Jessica Baker in Cheaper by the Dozen (2003) and its 2005 sequel, both starring Steve Martin. Those films were commercial hits, with the original grossing over $190 million worldwide. Child actors in studio ensemble films typically earn between $5,000 and $25,000 per week depending on their role, billing, and union rates.
She also played Lucy Miller in The Santa Clause 2 (2002) and The Santa Clause 3: The Escape Clause (2006) alongside Tim Allen. The third installment earned over $110 million at the global box office. These two franchises alone gave her substantial early earnings and real Hollywood credibility before she turned 13.
Voice Acting: The Smart Career Move
As she aged out of child roles, Mumy made a calculated move into voice acting. This was not desperation. It was strategy. Voice work offers consistent employment, residuals, and freedom from the physical demands of on-camera performance.
Her voice credits read like a checklist of beloved animated shows:
| Series | Role | Years Active |
|---|---|---|
| Lilo & Stitch: The Series | Mertle Edmonds | 2003–2006 |
| Higglytown Heroes | Twinkle | 2004–2007 |
| Chowder | Panini | 2007–2010 |
| The Cleaner | Lula Banks | 2008–2009 |
| Winx Club: Power of Believix | Roxy | 2012 |
| Bravest Warriors | Beth Tezuka | 2012–present |
| The Loud House | Leni Loud | 2016–present |
| Be Cool, Scooby-Doo! | Various | 2017 |
The Loud House is her biggest ongoing role. The Nickelodeon animated series premiered in 2016 and has run for multiple seasons, with films and specials including A Loud House Christmas still appearing as recently as 2025. A long-running animated series is one of the most reliable income sources in voice acting, offering session fees plus residuals each time an episode airs or streams.
According to industry data from the Screen Actors Guild, experienced voice actors on network animated series can earn between $800 and $2,500 per episode under union contracts, with additional residuals that can match or exceed the original session fee over time.
Awards and Industry Recognition
Industry recognition tends to bring higher-paying opportunities. Mumy has earned both.
She won the Young Artist Award for Best Young Ensemble in a Feature Film for Cheaper by the Dozen in 2004. She received a nomination in the same category for The Santa Clause 3 in 2006. In 2017, she won the BTVA Television Voice Acting Award for Best Vocal Ensemble in a New Television Series for The Loud House.
Winning a BTVA award is meaningful in the voice acting world. It signals to casting directors that your peers consider your work exceptional, which directly translates into more auditions and stronger negotiating leverage.
Comparing Mumy’s Net Worth to Voice Acting Peers
To understand where $4 million sits in context, consider a few comparisons. Voice acting is genuinely lucrative for its top tier. Nancy Cartwright, the voice of Bart Simpson, has a reported net worth of around $80 million, though she has worked on one of the longest-running shows in TV history for over 35 years.
Among voice actors who built careers through children’s animation rather than primetime, a $4 million net worth in your early 30s reflects consistent, professional-level work. It is not flashy money. It is the kind of steady accumulation that comes from booking role after role without major gaps.
Mumy’s position is particularly strong because her income streams come from multiple sources: syndication residuals from older shows like Chowder and Lilo & Stitch, active session work on The Loud House franchise, and any new projects she takes on.
Income Sources Driving Net Worth Growth
Mumy’s financial picture benefits from several revenue channels running simultaneously:
Residuals from legacy shows. Episodes of Chowder, Higglytown Heroes, and Lilo & Stitch: The Series continue to air in syndication and stream on various platforms. Every time those episodes air, she receives a residual payment. Over decades, these add up significantly.
Active series work. The Loud House franchise remains in active production. This provides current session income, not just passive earnings.
Convention appearances. Mumy has attended fan conventions, which typically pay appearance fees plus allow actors to earn from autograph signings and photo opportunities. These events can generate between $1,000 and $10,000 per day depending on the convention size and the performer’s draw.
Industry connections. Growing up with a father in the business gave her access to networks that most aspiring actors spend years trying to build. These connections have likely contributed to a steadier audition pipeline than many peers.
What Keeps Her Net Worth Growing
Several factors suggest Mumy’s $4 million is a floor, not a ceiling.
Voice acting ages well. Unlike on-camera roles where physical appearance becomes a constant variable, voice talent can work well into their 60s and 70s. Mumy is only 32. She has potentially four more decades of productive earning ahead.
The animation industry is expanding. Streaming platforms including Netflix, Disney+, and Peacock have dramatically increased demand for animated content. More shows mean more auditions and more opportunities for established voice talent.
She is not over-exposed. Mumy has managed her public profile carefully. She uses social media to share project updates without becoming a constant content machine. This kind of professional restraint tends to make casting directors view someone as focused on craft rather than fame-chasing.
