She will not be receiving $15,000,000 over 25 years. She still has to pay taxes on the money. 600,000 a year will probably be taxed at 33%. Which would mean she would receive about $400,000 a year which equals $10 million over the course of 25 years. This is where the math comes in handy. If you take $3.5 million out of the 4.5 million that she will walk away with from the lump sum payout and put it into an ETF fund with an annual return rate of 10% over 25 years, you would have $34,421,000. Even if she only received a 5% return annually on a 25-year investment, you would still be looking at about $8 million.
To be honest, she could put $4 million of the 4.5 million that she will receive into a six-month CD, take a financial education course, meet with multiple financial advisors, pay herself $10,000 a month for the next six months, and still have $440,000 after the course is over to be able to make a better financial decision with her money.
This is where people like Warren Buffett truly understands compound interest. Too bad it took me until I reach my 40s to understand this.
