A man worth over $100 billion wakes up every morning and asks himself a question that most of us never would: can I afford the bacon, egg, and cheese biscuit today, or should I stick with the sausage patties?
Warren Buffett — the Oracle of Omaha, the greatest investor alive, the guy who turned Berkshire Hathaway into one of the most valuable companies on the planet — has been eating McDonald’s for breakfast nearly every day for more than five decades. That alone is a fun fact. But it’s the way he decides what to order that makes this story genuinely weird.
The Exact Change System
Here’s how it works. Every morning, while Buffett is shaving, he calls out a dollar amount to his wife, Astrid. The number is one of three options: $2.61, $2.95, or $3.17. She takes that exact amount in coins and places it in a little cup in his car. Then he drives five minutes to the nearest McDonald’s, orders whatever that money buys, and heads to the office.
This whole ritual was captured in the 2017 HBO documentary Becoming Warren Buffett, and it’s one of those details that sticks with you long after you hear it. The $2.61 gets him two sausage patties, which he stacks together and washes down with a Coke. The $2.95 buys a sausage, egg, and cheese McMuffin. And the $3.17 — the big splurge — gets a bacon, egg, and cheese biscuit.
The difference between his cheapest and most expensive breakfast? Fifty-six cents.
The Stock Market Decides What He Eats
So what determines which dollar amount Buffett calls out on a given morning? The stock market. If the market is up, he feels prosperous, and he might treat himself to the $3.17 bacon, egg, and cheese biscuit. If the market is down, he scales back.
He said it himself in the documentary: “When I’m not feeling quite so prosperous, I might go with the $2.61, which is two sausage patties, and then I put them together and pour myself a Coke. $3.17 is a bacon, egg and cheese biscuit, but the market’s down this morning, so I’ll pass up the $3.17 and go with the $2.95.”
Let that sink in. A man who controls hundreds of billions of dollars in investments lets a bad day on Wall Street talk him out of spending an extra twenty-two cents on breakfast. This is the same person who, in a single two-week period, scooped up over 7 million shares of Occidental Petroleum. But the bacon biscuit? That requires a green market.
He Has a Card That Gets Him Free McDonald’s for Life
Here’s the part that makes the whole thing even more absurd. Buffett doesn’t need to pay for McDonald’s at all. He owns a rare McDonald’s Gold Card — one of very few in existence — that entitles him to free food at any McDonald’s in Omaha for the rest of his life.
He showed the card off during a 2007 CNBC interview with Becky Quick and joked that it’s the reason the Buffett family has Christmas dinner at McDonald’s. His friend Bill Gates also has one of these cards, but Gates got an upgrade — his works at any McDonald’s anywhere in the world. Buffett’s only works in Omaha. But since Buffett almost never leaves Omaha, he figured his card is just as good.
And yet, despite owning a literal free food pass, the man still insists on paying with exact change from a cup in his car. Every single day.
He Eats Like a Six-Year-Old on Purpose
McDonald’s breakfast is just the start. Buffett’s entire diet reads like a kid’s birthday party menu. He drinks at least five cans of Coca-Cola every day — regular Coke during the day, Cherry Coke at night. He snacks on cookies and ice cream. He loves hot dogs, fries, and popcorn. When he travels, his breakfast might be a pack of Oreos, according to Bill Gates.
Buffett has a joke he tells about this, and he’s used it multiple times over the years. “I checked the actuarial tables, and the lowest death rate is among six-year-olds,” he told Fortune. “So, I decided to eat like a six-year-old. It’s the safest course I can take.”
He’s also said, more bluntly: “If somebody told me I would live an extra year if I ate nothing but broccoli instead of eating what I like, I would say take a year off the end of my life and let me eat what I like to eat.” He once described broccoli, asparagus, and Brussels sprouts as looking like “Chinese food crawling around on a plate.” Cauliflower almost makes him sick. His idea of a vegetable? Green beans, corn, and peas.
At Berkshire Hathaway’s 2025 annual shareholder meeting, Buffett — still seated with two cans of Coke and a box of See’s Candies in front of him — defended this approach one more time: “For 94 years, I’ve been able to drink what I want, do what I want, and I’ve defied all the predictions of what should’ve happened to me.”
Fifty-Plus Years of the Same Routine
Buffett’s McDonald’s habit reportedly stretches back more than five decades. McDonald’s launched its full breakfast menu in 1977, and by 1984, prices ranged from 45-cent English muffins and hash browns to 89-cent sausage McMuffins. In 1985, his beloved bacon, egg, and cheese biscuit cost less than a dollar. By 2001, it was around $1.94. By 2017, it was $3.17.
As of a recent McDonald’s Facebook post, that same sandwich costs about $2.50. McDonald’s actually began rethinking its pricing approach in mid-2024 after reporting a 1% drop in same-store sales — the first decline since the pandemic. So the prices Buffett quoted in the documentary have shifted around over the years, though the ritual apparently hasn’t.
His daughter, Susie Buffett, confirmed in late 2024 that her father still lives in the same Omaha house he bought in 1958 for $31,500 — and still stops by McDonald’s for breakfast most days, well into his 90s.
A Frugal Billionaire Who Actually Means It
The McDonald’s breakfast thing isn’t a bit. It fits into a much bigger pattern. Buffett still works out of the same office building he’s been in since the 1960s. Berkshire Hathaway’s headquarters in Omaha employs about 25 people. There are no committees, no public relations department, no investor relations team, no general counsel.
He drives about 3,500 miles a year and buys a new car very infrequently. When his first child was born, he converted a dresser drawer into a makeshift crib. His hobbies aren’t yachts and art collecting — he plays bridge about eight hours a week.
This is a guy whose net worth sits around $116 to $128 billion depending on when you check, and he’s agonizing over whether the Dow Jones earned him a bacon biscuit today. It’s hard to tell where the genuine frugality ends and the performance begins. Maybe it’s both. Maybe after 94 years, the two are the same thing.
The $10 Billion McDonald’s Mistake
For all his love of McDonald’s food, Buffett doesn’t own any of the company’s stock anymore. And that bugs him.
Berkshire Hathaway once held millions of McDonald’s shares, but Buffett sold them in the late 1990s. In a shareholder letter, he admitted: “In particular, my decision to sell McDonald’s was a very big mistake. Overall, you would have been better off last year if I had regularly snuck off to the movies during market hours.”
The timing was brutal. After Buffett sold, McDonald’s went on a long stretch of outperformance. Since 2003, the stock has ended the year in the red only twice. The share price now sits just above $341. If Buffett had held on, Berkshire’s stake would be worth roughly $10.3 billion today — and that’s not counting dividends.
It’s a painful irony. The man who eats McDonald’s every morning, who has a Gold Card in his wallet, who lets the stock market pick his sausage-to-bacon ratio — that man sold his McDonald’s stock too early and lost out on billions. Even the Oracle of Omaha gets it wrong sometimes.
What the Breakfast Rule Is Really About
Some people have tried to read deeper meaning into Buffett’s breakfast system. One theory suggests it helps him avoid the ostrich effect — a cognitive bias where people deliberately ignore bad news. By tying his breakfast directly to market performance, maybe Buffett forces himself to acknowledge a down day before he even walks into the office. The sausage patties become a little reminder: yesterday wasn’t great, pay attention today.
Or maybe it’s simpler than that. Maybe a guy who has spent his entire life thinking about value and price and the relationship between the two just can’t turn it off, even at the McDonald’s drive-through at 7 a.m. When you’ve been wired to think about money for 94 years, everything becomes a financial decision — including whether you’ve earned the bacon.
Buffett once wrote: “If you aren’t willing to own a stock for 10 years, don’t even think about owning it for 10 minutes.” He’s applied the same principle to breakfast. He’s been eating the same three meals from the same restaurant for half a century. No menu changes. No new restaurants. No broccoli. Just sausage, McMuffins, and Coke — every single morning, rain or shine, bull or bear.
At 94, having just stepped down as CEO of Berkshire Hathaway after 60 years, Buffett seems perfectly content with the system. He told shareholders he and Charlie Munger never really exercised much. “We were carefully preserving ourselves,” he said. And then he probably went home, checked the market futures, and told Astrid how much change to put in the cup.
