Warren Buffett amassed 98% of his $160 billion net worth after turning 65, according to data shared by Creative Planning CEO Peter Mallouk. In 1990, Buffett’s net worth was $3 billion, which has since compounded over 5,200% thanks to long-term investing and the power of compound interest, which Buffett himself has called the secret to his wealth. The Berkshire Hathaway CEO continues to outperform major indices in 2025, with BRK returning 13.47% year to date, versus just 0.13% for the S&P 500 ETF. Berkshire is also holding a record $348 billion in cash. Top Berkshire holdings include Apple, American Express, Bank of America, and Coca-Cola.
