As the CEO and largest shareholder of Berkshire Hathaway, Warren Buffett has made several successful strides, including generating average annual returns of 19.8% between 1965 and 2023 – roughly double what the S&P 500 gained over the same period, according to The Motley Fool.
We look at how Warren Buffett built his fortune and the factors contributing to his net worth today.
Warren Buffett’s early years
Born in 1930 in Omaha, Nebraska, Buffett showed an early interest in business. Buffett's father was a stockbroker and served as a role model for the young investor.
As a child, he would buy six packs of Coca-Cola for 25 cents and sell each bottle for a nickel, making a tidy profit. He also started a pinball business and purchased the newspaper Buffalo News in 1977.
Buffett grew his newspaper business over the years with the addition of local papers — but in 2020, he decided to sell 31 newspapers for $140 million.
After high school, Buffett attended the University of Nebraska but transferred to the University of Pennsylvania's Wharton School of Business.
In 1951, Buffett received his master's degree in economics from Columbia University. At age 24, he received a job offer from Graham, with a salary of $12,000, reports Dividend Growth Investor.
His annual salary was thrice the annual median income for an average family in 1954, according to US Census Bureau data, which means Buffett was already well on his way towards accumulating wealth. Two years later, his net worth was already $140,000.
Warren Buffett's early partnerships significantly influenced his success as an investor and businessman. In the 1950s and 1960s, Buffett formed several partnerships that allowed him to pool his resources with other like-minded investors. These partnerships enabled him to invest in larger and more complex deals than he would have been able to do on his own.
How Benjamin Graham inspired Warren Buffett

Buffett studied at Columbia University’s Business School under Benjamin Graham, a renowned value investor who would later become his mentor.
Benjamin Graham is considered to be the father of value investing. He began his career in finance in the early 1920s, although he quickly realised that most investors were focused on short-term gains and speculation rather than investing in companies with strong fundamentals, such as robust balance sheets.
With this knowledge, he went on to develop his own investment philosophy, focusing on buying undervalued stocks. He believed buying equities cheaply, holding them for the long term and selling them when the market had realised the value was a great way to make money. Put simply, Graham believed that by carefully analysing a company's financial statements and other fundamental data, he could identify stocks trading at a discount to their true value.
This mentality shaped Warren Buffett's view of the world from a young age.
How Warren Buffett built Berkshire Hathaway
One of his most significant deals was Berkshire Hathaway. When Buffett first started buying the stock in the late 1950s, the business was a struggling textile manufacturer. He decided to try to buy enough shares in the business to force management to buy him out at a higher price — earning a handsome profit.
Management refused and Buffett lashed out, buying control and kicking the former management out.
Over the next few years, Warren Buffett wrestled with the business. He kept a tight rein on costs and used any excess cash to expand and diversify.
He started building on his empire with the acquisition of two small insurance groups. These companies gave Buffett an edge. Insurers have large portfolios of investments, giving Buffett a lot of flexibility around where and when he could invest. Over the years, the company has continued to acquire other insurance companies, including GEICO and General Re.
Despite these additional investments and diversification, Berkshire’s insurance businesses remain at the core of the group today. Berkshire Hathaway also owns a load of other well-known companies, including the battery brand Duracell and Dairy Queen ice cream parlours. Buffett now has 41 stocks in his Berkshire Hathaway portfolio.
Warren Buffett’s investing style
Buffett is known for his successful investing style. Historically, he has searched for undervalued companies that have a strong foundation and a competitive edge within a specific market. He then invests in these companies for the long term.
As a result, he has made impressive returns. Some of Berkshire Hathaway’s famous investments include Apple, Coca-Cola, American Express, Moody’s and several Japanese trading houses like Mitsubishi.
Looking to the future, Buffett has said is not keen on the use of artificial intelligence (AI).
According to The Motley Fool, Buffett expressed the opinion at the May 2024 Berkshire Hathaway shareholder meeting, comparing AI to a genie in a bottle: “It’s partway out of the bottle. We may wish we’d never seen that genie, or it may do wonderful things.”
Buffett is also known for his philanthropic efforts, including his commitment to giving away the majority of his wealth through the Giving Pledge – a commitment by some of the world's wealthiest individuals and families to give away the majority of their wealth to address society's most pressing problems.
