Rag'n'Bone Man has used the money from his hit album to buy a "nice set of kitchen knives and saucepans".
The 'Human' hitmaker catapulted to fame with his hit single and LP of the same name but he insists he has only used the money to treat himself to small things so far.
He said: "People think all musicians are millionaires, but, even if you are successful, you don't get to see that money for a long time. I've been able to treat myself - I bought a nice set of kitchen knives and saucepans. I love cooking. Beth's vegetarian and I do a veggie fry-up for lunch."
And if the music didn't work out in the end, the 32-year-old singer would be straight back to work as a carer.
He added: "After I left school, I washed cars for five years, then became a carer for children with Down's syndrome. I'd never considered music as a career.
"I did local gigs when I was at school, and every year it just kind of grew. Then, suddenly, it went haywire. I released the Human single last year and my debut album earlier this year, and it got to No 1. How did that happen? ...
"If the music career comes to an end, I'd go back into the care industry. You've got thousands of stressed-out parents of disabled children getting no help."
And the 'Skin' hitmaker - whose real name is Rory Graham - insists his new focus is getting health for his son Reuben, who he shares with his partner Beth Rouy.
He told The Sunday Times magazine: "Since Reuben was born, I've tried to look after myself a bit more. I've always been big - I was 6ft even in year 10 - but I've never felt unhealthy. And it doesn't worry me from a vanity point of view. But I would like to lose a stone or two for the boy. I've started swimming in the afternoon and cut down on the smoking - not to mention the recreational smoking. When I'm not on tour, nights are just me, Beth and Reuben."
