The 19-year-old rapper claimed that he made his fortune after releasing first single 'Crank That' and debut album Souljaboytellem.com in 2007.
Discussing the idea behind the book - entitled Teenage Millionaire - Soulja Boy told Billboard: "I made my first million dollars when I was 16 years old.
"I came from a place where a lot of people don't make it out to see the type of things I've seen around the world and see the amount of money that I've obtained. I just wanna tell all the people how I did it."
He added: "One of the chapters of my book is called 'Speaking It Into Existence'. It's something I've been doing my whole career. When you think or speak from the non-conscious it happens.
"When you weed out all the negative thoughts and focus on nothing but what you wanna have it's so easy to obtain it."
Teenage Millionaire will be released later this year.
