Last month, The Hollywood Reporter claimed that in 2010 the Kardashian clan made the massive combined figure as a result of all of their business deals, which include three hit reality TV shows.
Now the most famous member of the family has revealed that she gives 10 per cent of her share away to charity.
The 30-year-old Keeping Up With The Kardashians star tells Self magazine: 'Donating to charity makes me feel good.
'I give away 10 per cent of my money to different charities, like the Dream Foundation. If I can help someone with a terminal illness visit a loved one they might not have been with for 10 years, it's the greatest feeling in the world to me.”
She adds: 'If you give [money] away, you'll always prosper.'
The Kourtney & Kim Take New York star is said to charge $25,000 a time for personal appearances and also reportedly earns thousands of dollars by endorsing products on her Twitter page, which boasts six million followers.
She also has a number of endorsement deals, which include promoting the Skechers shoe brand.
But she tells the US fitness magazine: 'Everything in life isn't measured by money. Success is how you live your life and treat other people.
'I've always lived my life trying to be a good and considerate person. To me, love and family are everything.”
