Toby Fox has never stated his net worth publicly, and no financial disclosure exists for him. What’s verifiable instead is the trail of numbers around his career: a $5,000 Kickstarter goal that turned into $51,124, sales figures reported by Forbes and Wikipedia’s cited press sources, and a steady stream of paid composing work for Nintendo and other studios. This piece sticks to that trail rather than the guessed dollar totals that circulate on fan and finance blogs.
Fox is known for staying out of interviews, so almost everything here comes from named outlets, his own social posts, and public records like his Kickstarter page.

How Undertale Actually Started
Fox funded Undertale through Kickstarter in June 2013. He asked for $5,000. The campaign closed with $51,124 from 2,398 backers, according to the project’s own Kickstarter page, which is still public.
That’s a real, checkable number. It’s also a small fraction of what the finished game would go on to earn, since it only covered early development costs, not lifetime sales.
Undertale released in September 2015. Fox built almost the entire game solo — design, code, writing, and music — bringing in artist Temmie Chang for visuals. By the time Forbes named him to its 2018 30 Under 30 list for games, Undertale had sold more than 2 million copies. Later press coverage cited by Wikipedia puts lifetime sales above 3.5 million.
What Sales Figures Do (and Don’t) Tell Us About His Income
Nobody has published what Fox actually nets per copy sold. Steam, PlayStation, Xbox, and Nintendo all take a platform cut before a developer sees revenue, and Fox has never broken down his margins publicly.
That’s exactly why multiplying “3.5 million copies” by a guessed price point, the way many blogs do, doesn’t produce a real net worth figure. It produces a gross revenue guess for one game, built on an unconfirmed per-copy number, with no accounting for platform fees, taxes, refunds, or production costs. Famevora isn’t repeating that math here.
Deltarune and Ongoing Revenue
Fox has kept releasing Deltarune in chapters since October 2018. Chapters 1 and 2 were free. Chapters 3 and 4 launched as a paid release on June 4, 2025, alongside the Nintendo Switch 2, according to IGN and Eurogamer. On launch, Deltarune became the top-selling game on Steam and reached a peak of 133,224 concurrent players, per TweakTown’s coverage of SteamDB data.
Chapter 5 is confirmed for a 2026 release, which IGN reported in June 2025. Fox has said Deltarune is planned to run to seven chapters total, meaning the game is still an active, ongoing revenue source rather than a one-time release.
Income Outside His Own Games
Fox composes for hire. He’s written or contributed music to Nintendo’s Pokémon Sword and Shield and Pokémon Scarlet and Violet, Super Smash Bros. Ultimate, and Game Freak’s Little Town Hero, among other titles, according to Polygon, NME, and GameSpot. None of these outlets have reported his fee for this work.
He also sells official merchandise through Fangamer, and in September 2025, an Undertale 10th-anniversary charity livestream that Fox took part in raised more than $320,000 for Doctors Without Borders, as reported by GamesRadar+. That figure went to charity, not to Fox personally, but it’s a real, sourced data point about the scale of his fan base and its spending.
Why There’s No Verified Net Worth Number
Fox rarely gives interviews and hasn’t discussed his finances in the ones he has done. No SEC filing, court record, or verified statement from him puts a number on his wealth. Search results for “Toby Fox net worth” currently return estimates from $3 million to $15 million, depending on the site — a five-fold spread that’s a clear sign none of these figures are reliable. They appear to be built on the same kind of unverified sales-times-price math described above, sometimes on sites that also get basic facts wrong, including his name.
Famevora isn’t going to add another guess to that pile. If Fox or a court record ever puts a real number on it, this page will be updated.
