Could Investing $10,000 in Berkshire Hathaway Stock Make You a Millionaire?

While a $10,000 investment in Berkshire Hathaway at its 1980 IPO would be worth $25 million today, such returns are unlikely to repeat. A $10,000 investment made 30 years ago is worth only $230,000. To turn $10,000 into $1 million requires either 17% annual returns over 30 years or 12% annual returns over 40 years. The key factor is time, as most gains materialize in the final third of the investment period through compounding.
