Even Spending US$ 10 Million Per Day, Elon Musk Would Take Almost 137 Years to See His Net Worth Run Out, According to Calculation Based on the US$ 500 Billion Estimated by Forbes in October 2025
If Elon Musk decided to spend US$ 10 million every day, it would still take about 50,000 days — or approximately 136.9 years — to see his net worth reach zero. The estimate is based on the value of US$ 500 billion, a figure that Forbes attributed to the businessman in October 2025.
This calculation is impressive because it shows the distance between a billionaire fortune and regular consumption. Even with nearly inconceivable daily spending, Musk would remain “rich” for over a century.
Fortune Built on Companies
Much of this value is not in cash but in stocks and stakes in giants like Tesla and SpaceX.

Therefore, to actually spend US$ 10 million per day, he would have to sell stocks, liquidate investments, or drastically alter the structure of his portfolio.
This detail is essential because Musk’s net worth is volatile and depends on the market value of his companies.
A drop in stock prices can reduce billions of dollars in a matter of hours — something that happens frequently in the corporate world.
What the Calculation Reveals
The exercise is mathematical and does not consider factors such as taxes, debts, or investment income.
Still, it illustrates the magnitude of wealth well. Even immense sums being “burned” daily, the impact would be slow.
Moreover, the example helps to understand why billionaires rarely become poor simply due to excessive spending.
The real risk for fortunes of this size often lies in poor business decisions, global crises, or changes in the financial market.
A Wealth for Multiple Generations
In the end, if Musk really followed this spending pace, he would only become “poor” in 137 years. In other words, his current fortune would ensure luxury and financial power not only for him but also for several future generations.
