Tesla (NASDAQ: TSLA) and SpaceX CEO Elon Musk deliberately tested living on roughly $1 a day for food after arriving in North America as a teenager, not as a stunt but as a survival exercise.
Musk said the goal was to prove to himself that even if every ambitious business idea collapsed, he could still get by on almost nothing.
“I figured I could be in some dingy apartment with my computer and be okay and not starve,” Musk told astrophysicist Neil deGrasse Tyson on “StarTalk Radio” in 2015.
Musk explained that he tested the idea shortly after moving to Canada at 17, before eventually attending the University of Pennsylvania.
“I’d try to live on $1 a day, which I was able to do,” Musk said, adding that the strategy relied on buying food in bulk at the supermarket.
When Tyson guessed the diet consisted of rice and beans, Musk corrected him with a more specific answer about his actual menu.
“Yeah, I went more for the hot dogs,” Musk said. “Hot dogs and oranges. But you do get really tired of hot dogs and oranges after a while.”
To stretch the budget even further, Musk said he leaned on cheap, filling staples that could cover several meals without much cost.
“You know, pasta and green pepper and a big thing of sauce, that can go pretty far too,” Musk told Tyson.
The math behind the experiment was straightforward and deliberate, giving Musk a mental threshold for the minimum cost of staying alive.
“So I was like, oh, okay, if I can live for a dollar a day, then at least from a food cost standpoint, it’s pretty easy to earn like $30 in a month,” Musk said.
In the early 1990s, Musk’s $1 daily food budget worked out to roughly $30 a month, which adjusted for inflation equals a little more than $2 a day now.
Modern grocery prices have moved considerably faster than that inflation adjustment, with a basic pack of hot dogs today easily costing $5 or more.
A single orange can run close to a dollar depending on location and season, while pasta remains relatively affordable but sauce and vegetables add up quickly.
Recreating Musk’s old grocery routine today would realistically land somewhere between $3 and $6 a day, even with aggressive bargain shopping and bulk purchases.
Musk described the experiment as a psychological baseline that made entrepreneurship feel significantly less frightening once the worst-case scenario seemed manageable.
That mindset later shaped some of the largest business bets in modern history, including Tesla surviving near-collapse during the financial crisis and SpaceX enduring multiple failed rocket launches before eventually succeeding.
Musk’s story highlights why some investors continue backing startups and ambitious founders despite enormous risks, given that transformational companies are often built by people willing to tolerate sustained uncertainty and discomfort.
The broader lesson from his hot dog budget was never really about frugality, but about eliminating fear as a barrier to taking bigger risks once basic survival no longer felt terrifying.
