It will come as no surprise that when Prince died less than two years ago, he left behind a lot of money. What is interesting is how much money he had in cash.
According to The Blast, Prince, in addition to his assets, had over $40 million in cash when he died on April 21, 2016.

Court documents, filed on Jan. 31, show that the music icon left behind an embarrassment of riches… literally. Under his name alone, he left behind $18,719,062 in cash, in addition to several sealed boxes that are labeled as concert tributes and official records. He also owned seven homes in Minnesota.
He had more cash in various music companies he owned, too, the Blast said. Paisley Park Enterprises had $1,178,991.29 in cash left behind. There was also six cars and four homes left behind under that name.

One of his companies called NPG Music Publishing had nearly $12 million in cash and another home. An additional company that he owned called NPG Records holds more than $8 million in cash.
Several other companies owned by Prince had small cash on hand, but rang in at $155,000.
Although his estimated net worth was reported to be about $300 million around the time of his death, TMZ reported at the time his net worth was actually in the $150 million area.
Prince died of opioid overdose.
