At what age do people reach the peak of their wealth?

Optimized wealth management, major advances in medicine, and increased life expectancy: the peak of global wealth has been significantly impacted by all these factors, not to mention changes related to income and retirement pensions.

The 18–24 age group has the lowest incomes and, without savings or investments, cannot build substantial wealth. Between the ages of 25 and 50, however, households reach financial maturity and begin to invest. It is only after the age of 50 that earned income reaches substantial levels (estimated at nearly 30,250 euros net per year). While this period used to be described as the “prime of life,” its onset has been steadily pushed back. In France, it was around age 55 in 1998, then age 60 in 2010. Today, the peak of wealth has shifted to age 75. It’s important to note, however, that inflation and purchasing power continue to dictate this trajectory.

Does net worth equal wealth?

In France, the average net worth of a 75-year-old is approximately 360,000 euros, an indicator of financial comfort. Yet, in terms of net worth, inequalities persist. The assets of the wealthiest 10% consist of diversified financial and professional assets, while those of the least wealthy 10% are limited to so-called “durable” assets, often associated with heavy debt.

This social divide is further exacerbated by inheritance: heirs, in fact, have twice as much wealth as those who do not inherit. This invisible mechanism of transfer—and of accumulation (of both debt and wealth)—is found on a global scale, although the disparities are even more pronounced there.

How old is the average millionaire?

Globally, the average age of a millionaire is estimated at 57. Here’s how the age groups break down:

• 50 to 60 years old: 35% of millionaires;
• over 60: 30% of millionaires;
• 20 to 40 years old: 7% of millionaires (a share that is constantly changing).

How did they get there? Thanks, in part, to a lifetime of hard work, but above all to massive investments and the snowball effect of compound interest.
