Decamillionaire: What Is It and How to Become One?

Reading Time: 5 minutes

Decamillionaire is a term used to label a person with a net worth of more than 10 million. The currency in question can be any given currency, but it is most often US dollars. Other accepted currencies include Euros and the British Pound Sterling.  The history of the term “decamillionaire” originates from Ancient Greece from the word “deca,” meaning ten, and “millionaire,” representing one million.

Decamillionaire represents successful and wealthy individuals. They have made their wealth through entrepreneurship practices or, in many cases, inherited it. Becoming a decamillionaire is possible, but everyone would be a decamillionaire if it were that easy. Regardless, the question of “how to become a decamillionaire” boggles the minds of millions of people. 

So, let’s learn more about decamillionaires and even see how becoming one is possible.

When to Use the Term Decamillionaire, Multimillioinare, and Millionaire? 

The terms decamillionaire, multimillionaire, and millionaire label individuals based on their net worth. Individuals that make one or more than a million of any given currency can fall under these three categories. While an individual can also be a billionaire, we will focus specifically on these three categories.

  • A millionaire is a person with a net worth of one million in any given currency.
  • A multimillionaire is a person with a net worth of more than one and less than ten million in any given currency.
  • A decamillionaire is a person with a net worth of over ten million in any given currency. 

Based on that, we can use each term to more precisely reflect an individual’s net worth. So, for example, we can use “decamillionaire” to refer to an individual with a net worth of $13 million, but not if they have a net worth of $7 million.  

MillionaireOver $1 million
MultimillionaireOver $1 million and less than $10 million
Decamillionaire Over $10 million

How Many Decamillionaires Are in the World?

Our world has a population of around 7.8 billion. Many experts are claiming that the world population will soon eclipse 8 billion. But how many of these 7.8 billion people have a net worth of more than ten million? 

  • It is estimated that there are around 22 million millionaires in the United States from the overall number of 65 million. This number suggests that 33% of the world’s millionaires live in the United States
  • It is estimated that there are around 1,800,000 + decamillionaires in the United States, which is significantly lower than the number of millionaires. This number represents 8.8% of millionaires in the United States. The rest of the world combined has a number of 800,000 decamillionaires, putting the total number at 2,600,000 decamillionaires
  • Decamillionaires make up only 0.03% of the world’s population

What Are the Traits of Decamillionaires? 

There is no one-size-fits-all rule when examining the traits of decamillionaires. However, one thing for certain is that decamillionaires have managed to amass a significant amount of wealth. The problem is that many wealthy individuals in the world leave an inheritance to their children. This means that, even though millionaires generally have managed to accumulate wealth through hard work, that is not often the case. 

However, we can still look at some character traits of the most successful individuals to come to some conclusion. So, here are some trait commonalities shared between decamillionaires:

Strong Business Acumen 

Self-made decamillionaires tend to have a deep understanding of business and finance. Many of them have started and grown successful businesses, and they often have a knack for spotting opportunities that others may overlook. 


Self-made decamillionaires are not deterred by failure. In fact, many of them have experienced setbacks and failures along the way to their success. However, they persist and keep working hard until they achieve their goals. Hard work and persistence are key traits of any successful individual.


Decamillionaires are notorious risk-takers. They are willing to invest in new ventures and explore new opportunities, even if the risk is great and there is a chance of failure. As Elon Musk, CEO of SpaceX and Tesla, once said: “When something is important enough, you do it even if the odds are not in your favor.”

Strong Work Ethic 

Decamillionaires tend to be highly driven and hardworking individuals. They are focused on achieving their goals and willing to put in the effort and hard work necessary to make it happen.


Decamillionaires tend to be disciplined with their finances, despite being risk-takers. While this doesn’t necessarily mean that they live below their means, they tend to have a long-term mindset and are willing to delay gratification to achieve their financial goals. However, it’s important to mention that spending habits and discipline are traits not synonymous with every decamillionaire.  

Continuous Learning

Decamillionaires tend to be lifelong learners. They constantly seek new knowledge and skills and are not afraid to ask for help or advice when needed.

Strategic Thinking

Decamillionaires tend to be strategic thinkers. They can see the big picture and make decisions to help them achieve their long-term goals.
