The term "frugal billionaire" may seem like an oxymoron, but a small subset of the richest of the rich are well-known for their penny-pinching ways. While most people will never have that kind of money to throw around, everyone can take a page from the fiscally-responsible habits of these billionaires.
Warren Buffett, famed value investor and Berkshire Hathaway (BRK.A, BRK.B) CEO, lives a modest lifestyle despite his net worth of around $84 billion. He purchased a five-bedroom house in Omaha in 1958 for $31,500 and has lived there ever since. Buffett doesn't spend his money on electronics and reportedly doesn't carry a cell phone or have a computer at his desk.
Although he could afford a whole fleet of limousines to be at his beck and call, he prefers to drive himself and owns a Cadillac XTS, which he bought for $45,000 in 2014. When it comes to entertainment, the investment mogul shuns splashy parties and trips and spends his time playing bridge.
Facebook (FB) CEO Mark Zuckerberg makes the list as one of the world's youngest billionaires. This Facebook creator has an estimated net worth of $70 billion. Almost all of his money is tied up in the social media company's equity.
By all accounts, Zuckerberg keeps his life low-key and spends up to 60 hours a week at Facebook's Palo Alto office. Zuckerberg chooses t-shirts and jeans over expensive tailored suits and sneakers and sandals over Italian leather loafers. His one big indulgence seems to be real estate, as he has a portfolio of over $40 million in properties, including homes in Palo Alto, Calif., and one in San Francisco's Mission District.
Carlos Slim Helu
Among the richest people in the world, Carlso Slim Helu has an estimated net worth of over $61 billion. He built his fortune in Mexico, where he owns more than 200 companies including Telmex, the country's largest telephone service provider.
Slim shares many frugal traits with Warren Buffett, including living in a modest home and eschewing computers. Widowed since 1999, he spends most of his downtime at home with his children and grandchildren. In a country where security is often sketchy, he still chooses to drive himself wherever he goes. Although much more dandily dressed than Mark Zuckerberg, Slim purchases most of his clothing off the rack from one of the many retail franchises he owns.
John Caudwell, now retired from the British cellphone empire—Phones 4u—he built from scratch, owns many rich toys including a helicopter, yacht, and a car worth more than most people's homes. But when it comes to wasting money on everyday things, he's a stickler for saving.
Cauldwell has an estimated net worth of $2.4 billion, but he cuts his own hair because he thinks barbershops are a waste of time and money. He buys his clothing off the rack at the British retailer Marks and Spencer. Before retirement, he would bike 14 miles to work each day rather than have someone drive him in his Bentley. Now, he bikes 40 miles every week to and from his favorite pub.
The Bottom Line
The uber-wealthy don't always live the high life, which helps them stay rich. The frugal billionaires listed above all came from modest means, where frugality was learned and practiced by their families. They carried these lessons with them in business and, one hopes, they will pass them on to their children.
