This isn't the first time Buffett has recommended this investment. In 2008, for example, he bet $1 million that the S&P 500 (SNPINDEX: ^GSPC) could outperform a group of five actively managed hedge funds. His investment earned total returns of nearly 126% over 10 years, compared with an average of 36% for the five hedge funds.
Not only is an S&P 500 index fund a relatively safe and consistent investment, but it could also help you build a million-dollar portfolio. Here's how.

A long-term investment with a proven track record
While it's impossible to say how any investment will perform in the short term, the S&P 500 itself has an impeccable long-term track record. The key is to stay invested for as long as possible.
Over the last century, 26% of the S&P 500's one-year periods have ended in negative total returns, according to research from investment firm Capital Group. However, only 6% of the index's 10-year periods have resulted in losses. In other words, the longer you hold an S&P 500 index fund, the lower your chances of losing money.
Even if the market is volatile, it's still possible to build substantial wealth with enough time. Since 2000, the S&P 500 has faced the dot-com bubble, the Great Recession, a global pandemic, and the bear market of 2022. Yet it's also delivered total returns of more than 700% in that time.
If you'd invested $10,000 in an S&P 500 index fund in January 2000, you'd have around $83,000 by today. With smaller monthly contributions, however, you can get closer to a $1 million portfolio.
How to become a stock market millionaire
Time and consistency are your two most valuable resources when building wealth in the stock market.
Historically, the S&P 500 itself has earned an average rate of return of around 10% per year. At that rate, here's approximately how much you'd need to invest each month to reach $1 million, depending on how many years you can let your money grow.
| Number of Years | Amount Invested Each Month | Total Portfolio Value |
|---|---|---|
| 20 | $1,500 | $1.031 million |
| 25 | $850 | $1.003 million |
| 30 | $525 | $1.036 million |
| 35 | $325 | $1.057 million |
| 40 | $200 | $1.062 million |

No matter how much you can afford to invest each month, getting started sooner rather than later is key. Even a few extra years can potentially add up to hundreds of thousands of dollars.
Investing in the stock market is one of the most effective ways to generate long-term wealth, and there's a reason why the S&P 500 index fund comes highly recommended by Warren Buffett. With enough time, you could earn more than you might think with this investment.
