Six key biographical details set the stage:
| Label | Value |
|---|---|
| Full name | Nancy Jean Cartwright |
| Birth date | October 25, 1957 |

Is Nancy Cartwright a billionaire?
Short answer: no. Despite decades of iconic work, Nancy Cartwright’s net worth is firmly in the multi‑million‑dollar range — impressive, but not billionaire territory.
Nancy Cartwright’s net worth 2025
- Backstage (actor industry resource) pegs her net worth at $60 million.
- Voice123 (voice‑actor marketplace) also estimates $60 million.
- TVovermind (entertainment finance site) offers a higher estimate of $80 million.
- IMDb (film database) lists her among the “World’s Richest Voice Actors” with $80 million.
The implication: even the highest credible estimate — $80 million — is a fraction of a billion. Cartwright is a millionaire many times over, but not a billionaire.
How much did she make from The Simpsons?
- Reportedly earned up to $400,000 per episode during peak seasons (Voice123).
- That salary, compounded over 35 years and hundreds of episodes, accounts for the bulk of her wealth.
- Union baseline rates for TV and radio voice sessions typically run $250–$500 per session (Voice123), showing how exceptional the Simpsons pay is.
The trade‑off: such lucrative contracts are rare — only top‑tier animated series command those numbers.
How many Simpsons voices does Nancy Cartwright do?
Cartwright is a one‑person character factory. Besides Bart Simpson, she voices Ralph Wiggum, Nelson Muntz, Todd Flanders, and many more recurring and one‑off characters.
List of characters voiced by Nancy Cartwright
- Bart Simpson — the signature role (Wikipedia)
- Ralph Wiggum — the sweet, dim‑witted boy (Wikipedia)
- Nelson Muntz — the schoolyard bully (Wikipedia)
- Todd Flanders — Ned’s younger son (Wikipedia)
- Also voices Chuckie Finster in Rugrats (Wikipedia)
What is Bart’s IQ?
Bart’s intelligence fluctuates for comedic effect. No canonical IQ is fixed across all episodes, though he is generally portrayed as clever but unmotivated.
The pattern: Cartwright’s range is unmatched in television voice acting.
What religion is Nancy Cartwright?
Cartwright is a practicing Scientologist — a fact she has discussed openly in interviews and in her book My Life as a 10‑Year‑Old Boy.
Nancy Cartwright and Scientology
- She joined the Church of Scientology in 1991 (Wikipedia).
- In 2007 she received Scientology’s Patron Laureate Award after donating $10 million (Wikipedia).
- She has spoken about applying Scientology principles to her acting career.
Do Scientologists believe in Jesus?
Standard Scientology doctrine views Jesus as one among many spiritual figures, not as a divine savior. Individual beliefs, including Cartwright’s personal views, may vary but the official stance is non‑Trinitarian.
“I take responsibility for my own survival — that’s really the core of what Scientology teaches.”
— Nancy Cartwright, as cited by Wikipedia (encyclopedic reference)
Cartwright’s high‑profile Scientology affiliation stands at odds with her wholesome, family‑friendly on‑screen persona. That contrast has fueled both curiosity and criticism over the years.
The implication: Cartwright’s faith remains a defining and divisive aspect of her public image.
Is Sabrina Carpenter related to Nancy Cartwright?
No. Despite occasional internet speculation, Sabrina Carpenter — the singer and actress — has no blood relation to Nancy Cartwright.
Sabrina Carpenter and Nancy Cartwright’s connection
- They share the last name “Carpenter” but are not family (Wikipedia).
- Nancy Cartwright was married to Warren Murphy (1988–2002) and later to Stephen Brackett (engaged 2007, died 2009) (Wikipedia).
- No public records link Cartwright to the Carpenter family.
The catch: the misunderstanding likely arises from the surname overlap and a lack of clear biographical distinction in search results. A quick Wikipedia check resolves the confusion.
Who are the highest‑paid voice actors of all time?
Nancy Cartwright ranks high on the list, but she is far from the top earner. The real titans are the creators behind South Park.
Nancy Cartwright’s earnings compared to others
Here is how Cartwright stacks up against the highest earners in voice acting.
| Voice Actor | Estimated Net Worth | Peak Episode Earnings |
|---|---|---|
| Nancy Cartwright | $60–80 million | $400,000 (Voice123) |
| Matt Stone | $700 million (Backstage) | Not disclosed |
| Trey Parker | ~$500 million (based on combined $1.2B reported by Voice123) | Not disclosed |
What this means: while Cartwright’s $400,000 per episode places her among TV’s top earners, the South Park duo built a media empire that dwarfs individual voice‑actor salaries.
Net‑worth figures for celebrities are often rough estimates from public data. For Cartwright, the spread between $60 million and $80 million reflects different methodologies — not fraud, but imprecision.
The pattern: Cartwright’s earnings are impressive but fall short of the industry’s true financial titans.

Summary
Nancy Cartwright built a career on one of the most recognizable voices in animation, translating a single role into a fortune that makes her a wealthy woman — but not a billionaire. Her net worth, while substantial, remains a fraction of the wealth generated by the South Park creators. For fans and aspiring voice actors, Cartwright’s career shows that longevity on a hit show can yield millions, but building a media empire requires a different level of ownership and creative control.
