How outrageous is Bezos's fortune? His net worth is 240.9 billion USD, and even if he only invests 1% (2.4 billion), he can earn 6 million a month.

Conservative algorithm: With an investment of 2.4 billion at a 3% annual return, the monthly passive income would be 6.02 million. If you are more aggressive and use a high dividend portfolio with a 7% return, the monthly income can reach 14.05 million - without touching the principal.

Look at it from a different perspective: this monthly income is 59 times the annual income of a median family in Manhattan, New York, and equivalent to 101 years of income in Miami. With this income, you could buy a $6 million mansion every month; when it comes to dining, you could eat at a Michelin three-star restaurant every day without running out of money.

Interestingly, this amount of money is actually quite difficult to spend. With expenses for food, accommodation, transportation, entertainment, and donations, spending 3 million a month is already extravagant; the remaining amount still needs to be continually invested for growth. This is also why Bezos's wealth grows like a snowball—his income far exceeds his expenses.
