Will a billionaire’s son perpetuate his inherited fortune? Apparently not, if history is anything to go by.
In fact, there is robust evidence that the majority “rich families” will turn out to be poorer after several generations. Some of the explanations for this are systemic. For example, taxes reduce a family’s wealth. But a lot of the aspects that reduce a family’s wealth across generations are the selections of heirs. This includes how they invest their inheritance, what number of children they’ve, whether or not they divorce and other lifestyle decisions.

As Figure 1 shows, six of the ten richest people on this planet were “created” in ten years. And they were all men, which is why I exploit the term “patriarch” throughout this blog. Of course, the sample is simply too small to be statistically significant. But at first glance, Forbes’ top 10 list shows that capitalism has the power to create latest billionaires and create wealth. Another solution to take a look at it’s that capitalism is replacing billionaires who either have not been in a position to grow their wealth as quickly as others or have in some way lost it.
This raises quite a few fascinating questions: What does it take to show someone who was yesterday’s TOP10 billionaire into today’s TOP10 billionaire? Can the causes be transferred to other wealthy investors? If there isn’t any one-size-fits-all formula for becoming wealthy, is there a one-size-fits-all formula for losing a family’s wealth? Does the apple fall removed from the tree relating to generational wealth?
A model to elucidate the buildup capability of a mogul
To test a mogul’s ability to keep up their wealth for the subsequent five generations, we created a mathematical model that explains accumulation capability using seven variables:
- Amount of inheritance received (H)
- Number of heirs who will divide the assets (Q)
- (I)
- Number of years of accumulation (N)
- Annual expenses of the rich as a percentage of their family income (G)
- Divorce rate amongst wealthy people and the associated division of assets (D)
- Property tax (T)
Taking these variables into consideration, the longer term value that a patriarch will pass on to the second generation of his family can be:
FV= [(H x (1+i)N) + ((H x i) x (1-G)/Q) x ((1+i)N – 1)/i)] x (1-T)
And this cycle continues, from the second to the third generation, from the third to the fourth and from there on. Three aspects stand out in the buildup process: inheriting lots of money, having more time in the buildup phase, and obtaining the next return on investment. Conversely, 4 out of seven variables hinder wealth accumulation: having more children, overspending, getting divorced, and living in a rustic with a high wealth tax.
We test this query: Can a wealthy family accumulate wealth over multiple generations even while having more children, living a lavish lifestyle, dividing assets in a divorce, and paying a wealth tax?
You will notice that the variable “divorce” isn’t present in the fundamental formula. This is since it is random and binary. To test this effect in dynamic scenarios, we performed a Monte Carlo simulation, taking 10,000 scenarios into consideration. We considered the next values and probability distributions:
Amount of inheritance received
We start at $1 billion. This number was chosen arbitrarily and assumes that the patriarch left the family $1 billion upon his death and left all of it to his relatives (no philanthropy, no further donations, no relative denial or exclusion of an heir). And due to this fact we are able to determine the quantity that his son would save after his death, the quantity that his grandson would inherit, from now until the fifth generation of the family.
We recognize that all and sundry has their very own inclination to depart a legacy and that this may increasingly vary depending on cultural norms. It doesn’t just rely upon accumulating great wealth over a lifetime. The propensity to depart this legacy also varies depending on the style of legacy. Heritage could be tangible (buildings, cars, boats) or intangible (human values, personal branding, political power).
We also know that a billionaire’s propensity to depart an inheritance doesn’t correlate together with his wealth. Jeff Bezos and Elon Musk donate lower than 1% of their wealth, and the more they enrich, the less they donate, as a percentage.
Number of heirs who will divide the assets
How many children does a billionaire have? Is it significantly different from an strange middle-class person? Elon Musk, for instance, has nine children with three different women as of this writing. According to Forbes, just like the 700 richest people in America, Elon Musk is an outlier a median of two.3 children, and only 22 of those 700 billionaires have seven or more children. If we interpolate this and assume a standard distribution, we arrive at a normal deviation of two.39.
Affluent’s annual net return
This might be essentially the most difficult variable to model. What is the typical annual return for a billionaire? High returns are the variable that caused Elon Musk to go from anonymity to the highest of the billionaires list in lower than 10 years, and Carlos Slim to fall from the highest of the list to number 20.
In practice, we see that a billionaire’s return is volatile. First, many have leveraged their returns. They own corporations that tackle debt, and a few even use their very own assets. Second, lots of them invest their wealth in private stocks and enterprise capital, assets that produce high returns or perform poorly. Using the Dimson-Marsh-Staunton database (2017), returns from 1900 to 2017 for the wealthiest segment of the population averaged 4.8% per yr with a normal deviation of 15.1%.
Number of years of accumulation
How a few years does it take to build up your first million dollars? And the primary billion? According to the Financial planners Brian Preston and Bo HansonIt takes roughly 27 years for an individual to build up their first million (5.3 million Americans) and 14 more years to succeed in one billion (700 Americans).
However, we all know that this probability of becoming a millionaire isn’t exactly random. Even though only 3% of the population has reached the million-dollar milestone, an individual is 12 times more prone to reach this point after age 60 than they were 30 years ago. We know that whites and Asians are 4 times more prone to reach the million mark than blacks or Hispanics. Postgraduates are eight times more prone to reach the million mark than those whose education led to primary school.
Interestingly, 59% of millionaires earned their first million through entrepreneurship, 20% through inheritance, and 21% through work. And the probability of this happening is 44.1% A millionaire will end his life in poverty.
The annual spending of the rich as a percentage of their family’s income
An individual’s spending behavior is one other extremely sensitive variable. In an extreme but very telling example, Cornelius Vanderbilt’s family lost an estimated $400 billion (adjusted for inflation) in only three generations because of overconsumption.
According to the Bureau of Labor Statistics, the composition of an American family’s spending varies widely. Members of the lower economic classes spend 96% of their income on basic supplies and food. Wealthy people spend 85% on leisure.
Divorce rate amongst wealthy people
Divorce rates have increased amongst wealthy people. A mathematical model should take this trend into consideration. We used the American Community Survey most current dataThis shows that 44% of couples in the very best economic strata divorce.
Property tax
We measured the typical property tax. It is surprising how different each country’s wealth taxes are. Australia, Canada, Israel and Mexico haven’t any wealth tax. Japan has Eye opening 55%. In many other countries, the wealth tax is ready by each state and differs in the gathering rules. In São Paulo, for instance, the speed is 4%. In Santa Catarina, also in Brazil, the speed varies between 1% and eight%. We used the OECD median value of seven% in our model.
Simulation results
The simulation tried to predict what would occur to 10,000 people born to a billionaire. We found that some would overspend, make bad investment bets, pay high taxes on wealth transfers and lose the unique billion dollars. The effect would increase over subsequent generations. It’s possible that the fifth generation of this wealthy family is made up of middle-class staff who rise up early, get stuck in traffic, and struggle to pay their bills.
Figure 2. Generational wealth.
If a family made it to the fifth generation and had more or as much because the patriarch’s original $1 billion fortune, we considered them wealthy, and in some cases the gathered wealth was significantly greater than the quantity inherited. However, if the fifth generation of the family had lower than their patriarch had left, it is feasible that they passed this wealth from generation to generation for among the reasons mentioned above, and we considered this a degree of criticism.
Out of 10,000 simulations, the fifth generation family was wealthy in 43% of cases. Their cumulative average return was 5.008%. This signifies that in five generations, i.e. around 120 years, the family’s wealth has increased in real terms by around fifty times.
In most cases (57%), the fifth generation of the family had less wealth than they inherited and achieved a median cumulative return of -2000%. The simulation showed that wealthy families enrich less often but more in absolute returns. Critics lose more often, although the losses are less pronounced.
Overall, there is robust evidence that few wealthy families will proceed to be richer after several generations.
Diploma
The simulation shows that despite concerns about wealth concentration, a wealthy family is prone to weaken the patriarch’s legacy and that lifestyle and investment decisions are responsible. While a financial advisor may also help a family give attention to asset allocation and tax planning, the advisor’s role also includes wealth psychology and family leadership. The transmission of solid values across generations is the guarantee of stability and preservation of the wealth of a wealthy family.
