Nathan Fillion has an estimated net worth of $20 million, according to Celebrity Net Worth, Nathan Fillion net worth page (figures as of November 18, 2025).
Nathan Fillion is a Canadian-American actor who was born on March 27, 1971, in Edmonton, Alberta. He moved to New York City in 1994 and took the role of Joey Buchanan on the soap opera One Life to Live, which earned him a Daytime Emmy nomination in 1996. He has been a U.S. citizen since 1997.
He starred as Captain Malcolm Reynolds in Firefly in 2002 and in its film continuation Serenity in 2005. From 2009 to 2016 he played mystery novelist Richard Castle on Castle, and since 2018 he has starred as Officer John Nolan on The Rookie, where he is also an executive producer. He appears as Guy Gardner in the DC film Superman in 2025.
How Nathan Fillion makes his money
Television is the main source of income. Castle ran on ABC from 2009 to 2016 and The Rookie has been on the air since 2018, so he has been a network lead for most of two decades, with the steady episode fees that come with it. Before that, Firefly made him a favorite of science fiction fans.
As an executive producer on The Rookie and its spin-off The Rookie: Feds, he can earn more than an acting fee alone, and he is set to produce another spin-off, The Rookie: North.
Voice work and films add smaller amounts on top of that, since they are less steady than a network series. He voices Gunnery Sergeant Buck in several Halo games, appears in the Destiny games, and has voiced Hal Jordan in DC animated films. He also starred in the horror film Slither in 2006 and the romantic comedy Waitress in 2007, and he joined Desperate Housewives in 2007 for a season.
