Wealthiest Self-made People

Rags to Riches: The World’s Wealthiest People

For most of the world’s richest people, the journey to billionaire status is a marathon, not a sprint. It often involves decades of persistence, calculated risks, and unwavering dedication to their ventures.

Yet, a select group of entrepreneurs have defied this norm, riding on the wave of innovation and market demand to amass ten-figure fortunes in an astonishingly short period. From tech prodigies to finance wizards, these individuals have not only built successful companies but have also reshaped entire industries and consumer behaviours. 

Below, the online casino site Genting Casino has analysed the 50 richest self-made billionaires in the world to see which reached this esteemed benchmark the fastest.

Which billionaires made their money the quickest?

Top 3 Quickest Billionaire

1. Mark Zuckerberg (Facebook)

Age: 39

Year of first billion: 2008

Age of first billion: 24

Mark Zuckerberg is best known for co-founding the social networking site Facebook from his Harvard dorm room in 2004. Four years later, aged 24, he had made his first billion dollars. Initially created as a platform for Harvard students to interact, it quickly expanded to other universities and eventually to the general public.

Zuckerberg's meteoric rise to billionaire status can be attributed to the explosive growth of Facebook's user base and innovative monetisation strategies. The company went public in 2012, solidifying Zuckerberg's position as one of the youngest self-made billionaires in history. Despite criticisms and challenges, especially concerning privacy concerns and the platform's influence on public discourse, Facebook (now Meta Platforms, Inc.) remains a dominant force in the tech world.

2. Larry Page & Sergey Brin (Google)

Ages: 50

Year of first billion: 2004

Ages of first billion: 31

Larry Page and Sergey Brin, the dynamic duo behind the tech giant Google, met at Stanford University while pursuing their PhDs. Their collaboration led to them developing the “BackRub” search algorithm in 1996. Recognising its potential, they renamed it Google (a play on the mathematical term 'googol') and officially launched the company in 1998. The search engine's unique approach of ranking pages based on relevance quickly set it apart from competitors. Google's initial public offering in 2004 transformed Page and Brin into billionaires when both were just 31. 

Today, Google is part of Alphabet Inc., a conglomerate of various tech-related ventures. Both Page and Brin have been instrumental in refining search technology and spearheading innovations like self-driving cars, smart contact lenses, and more.

2. Michael Dell (Dell Technologies)

Age: 58

Year of first billion: 1996

Age of first billion: 31

Like Larry Page and Sergey Brin, Michael Dell made his first billion at age 31. Dell is best known as the founder of Dell Technologies, one of the world's leading technology infrastructure companies. 

Born in 1965, Dell started assembling and selling computers from his college dorm room at the University of Texas at Austin. By 1988, his company went public; in 1996, he reached billionaire status at 31. Dell's success can be attributed to his innovative direct-to-consumer business model and the company's diversification into various tech segments.

Billionaire Timeline

The technology sector stands out as the leading industry for rapid wealth creation. With individuals like Mark Zuckerberg reaching billionaire status at 24 and tech magnates like Sergey Brin, Larry Page, and Jeff Bezos becoming billionaires in their early to mid-30s, it's clear that technological innovation provides significant opportunities for swift financial growth.

2. Metals & Mining - Average age: 43

Elon Musk's achievements in the automotive industry with Tesla (and others) illustrate the renewed potential in this sector, especially with shifts toward sustainability and technology integration.

The US is home to a diverse range of billionaires across various sectors, from tech innovators like Mark Zuckerberg and Larry Page (billionaires at 24 and 31) to finance gurus like Warren Buffett, who reached the milestone at 56. The broad spectrum of opportunities and a mature market and innovation ecosystem have facilitated rapid wealth accumulation for many in the United States.

3. China - Average Age: 46

China's rapid economic growth and integration with global markets in recent decades have paved the way for entrepreneurs like Zhang Yiming, known for his role as the CEO of ByteDance, the parent company of TikTok, to amass fortunes relatively early in life.

British Billionaire Timeline

How long would it take the average person to earn £1 billion?

Average Person to Earn a Billion Timeline

Unsurprisingly, making these vast amounts would take the average person much longer. The average salary in the UK is currently £27,756. That means that even if you were to save 100% of your paycheck, it would still take you over 36,000 years to earn a billion pounds.

Of course, this varies by industry. For example, for those in the 'activities of households as employers' sector, which includes maids, cooks, gardeners, and other similar domestic roles, it would take over 125,000 years.

However, even in a higher-earning industry, which would take less time, we can still see how unattainable a billion pounds is for the average person. For example, those in the electricity, gas, steam and air conditioning supply industry earn an average of £44,303, but it would still take them 22,572 years to hit the milestone.

This reinforces the enormity of £1 billion, especially when juxtaposed against average industry salaries. It underscores the point that, while salaries can provide a comfortable living and even substantial savings, accumulation of wealth in the billions typically relies on strategies far beyond regular salaried income.


We looked at the 50 wealthiest people in the world (as well as each current British billionaire), according to Forbes’ World’s Billionaires List, excluding any that fully inherited their wealth.

For each, we found the year they first appeared on the list and, therefore, the year they became a billionaire. This was then used to calculate the approximate age at which each person became a billionaire.
