"Some billionaires seem confused about how much they would pay under my #TwoCentWealthTax," Warren tweeted after billionaires Bill Gates and Leon Cooperman expressed concern about how much they'd pay under her plan. "Don't worry, we've got a calculator for that, too."
The users of Warren's calculator can input any billionaire's net worth to see what they'd pay, or they can choose from names including Gates, Jeff Bezos, Michael Bloomberg and Betsy Devos's family.
Gates, for example, currently worth about $107 billion, would pay about $6.38 billion under Warren's tax plan, and Jeff Bezos, currently worth $111 billion, would pay about $6.7 billion, according to the calculator.
On Wednesday, when asked about Warren's tax plan at The New York Times DealBook conference, Gates said he would be "fine" paying $20 billion in taxes, but "you know, when you say I should pay $100 billion, then I'm starting to do a little math about what I have left over."
He added, "sorry, I'm just kidding. You really want the incentive system to be there and you can go a long ways without threatening that."
At the conference, Gates also said he's "all for super-progressive tax systems," and has been outspoken in the past about taxing the rich.
"I need to pay higher taxes," he told CNN's Fareed Zakaria in 2018. "I've paid more taxes, over $10 billion, than anyone else, but the government should require people in my position to pay significantly higher taxes."
Investor Cooperman teared up during an interview on Monday with Scott Wapner on CNBC's "Halftime Report," saying Warren "vilifies" billionaires.
According to Warren's calculator, Cooperman would pay $151 million under her tax plan. He currently has a net worth of $3.2 billion.
