Warren Buffett's had a good year — his fortune has ballooned by more than $16 billion so far.
With an estimated net worth of $124 billion, according to the Bloomberg Billionaires Index, the 93-year-old Berkshire Hathaway chairman and CEO is now the sixth-wealthiest person in the world. He's richer than Mark Zuckerberg, whose net worth is an estimated $111 billion, Google cofounder Sergey Brin, worth $116 billion, and former Microsoft CEO Steve Ballmer, worth $118 billion.
Looking at Buffett's frugal ways, though, you might not know it.
Still living in the house he bought in the 1950s and driving an equally modest car, the Oracle of Omaha prefers to keep and grow his money rather than take it out of the bank. He eats McDonald's for breakfast in the mornings and borrowed furniture when his children were born.
See how Buffett spends — or doesn't spend — his billions.
