Forbes’ methodology

The list "uses net worth earnings previously published for the Forbes 400Billionaires list and ranking of America's Richest Self-Made Women. Celebrities not on those lists were valued through private company stakes and publicly traded assets. Real estate, art and other assets were also factored in where applicable. For entertainers without such holdings, we based estimates on net lifetime earnings after taxes and spending. Eligibility was limited to American citizens who've gotten rich off their fame, rather than become famous for their wealth."
