What does JK Rowling do with her money?

Indeed, the scale of her wealth is such that it is hard to comprehend. It has been said she is richer than the Queen. She earns around £1million every three days. It is the kind of fortune it would be impossible to spend even if she stayed in that luxury pad in the Hamptons all year round.

Her life now is, naturally, very different from the hand-to-mouth struggle of the days before Potter was published. Back then, she famously nursed cold coffees in an Edinburgh cafe for hours as she wrote, her daughter Jessica sleeping in a buggy beside her. She subsisted on £70 a week benefits, and her flat was infested with mice.

And yet the story of what Jo Rowling spends her money on is far from a
predictable tale of conspicuous consumption. Indeed, it is a story
which provides a valuable and uplifting counterpoint to the circus of
pointless and continuous spending indulged in by other modern
celebrities like, say, Victoria Beckham.
