Facebook CEO Mark Zuckerberg blew past Berkshire Hathaway CEO Warren Buffett in net worth last week. The $20 billion difference in their fortunes isn't just a product of Facebook stock outperforming Berkshire stock; it also reflects Buffett giving far more than Zuckerberg to charity.

Buffett's net worth has plunged by more than $20 billion this year to about $69 billion, while Zuckerberg's wealth has swelled by about $11 billion to north of $89 billion, according to the Bloomberg Billionaires Index .

The roughly 23% slump in Berkshire shares since January has hammered Buffett's net worth, while the 14% surge in Facebook stock has boosted Zuckerberg's net worth over the same period. However, the scale of their philanthropy is another big factor. Buffett gave nearly $15 billion to charity between 2014 and 2018, dwarfing the $1 billion given by Zuckerberg and his wife, Priscilla Chan, according to a list of America's 25 biggest givers compiled by Forbes and SHOOK Research. There would be a much smaller gap in their net worths without those donations. Buffett would be worth about $84 billion, while Zuckerberg would be worth about $90 billion.

"More than 99% of my wealth will go to philanthropy during my lifetime or at death," Buffett vowed as part of The Giving Pledge , an initiative he launched with Bill and Melinda Gates in 2006 to encourage billionaires to give away the majority of their fortunes. "We will give 99% of our Facebook shares currently about $45 billion during our lives to advance this mission," Zuckerberg and Chan said in a public letter to their newborn daughter in 2015. The pair signed The Giving Pledge five years earlier , in 2010.
