Mary-Kate and Ashley Olsen have been around for so long — anybody born in the 90s couldn’t escape having heard their names at least once. Having begun their rise to super-riches with the help of sitcoms like Full House, the twins have an estimated net worth of $400m.
According to Cheat Sheet, as of 2019, the twins have a cool net-worth of $400m (although it’s probably actually a bit more. But nobody will ever know because the twins are super private).
