Microsoft co-founder Bill Gates said that he’s not leaving his three adult children as much money as some may expect from a tech billionaire father, noting he wants to give them the chance to make their own success.

The Microsoft co-founder made sure to point out that his three children “got a great upbringing and education.”

OK, so 1 percent might sound stingy at first, but if we do the math, that still works out at around $1 billion based on Forbes’s estimation that he’s worth about $108 billion. Going into more detail, Bill said leaving the kids any more than that “wouldn’t be a favor to them.”
