Biography
Known as the "Oracle of Omaha," Warren Buffett is one of the most successful investors of all time.
Buffett chairs Berkshire Hathaway, which owns dozens of companies, including insurer Geico, battery maker Duracell and restaurant chain Dairy Queen. He retired as CEO at the end of 2025.
The son of a U.S. congressman, he first bought stock at age 11 and first filed taxes at age 13.
He has promised to donate over 99% of his wealth. So far, he has given away nearly $65 billion, mostly through the Gates Foundation and his kids' foundations.
In 2010, he and Bill Gates launched the Giving Pledge, asking other billionaires to commit to donating at least half of their fortunes to charitable causes.
Perspective on their fortune
Gold
Everyday luxury
A Warren Buffett's fortune is equivalent to 954 of gold, but this may be difficult to value, as we don't usually have a handful of gold bars in our piggy bank.
A standard gold ring typically weighs between 4 and 7 grams. Let's say this one weighs 5 grams. It's usually 18k gold.
Based on today's gold price (not taking into account the jeweler's fee, shipping, or anything else), that gold ring would be worth $556.3
Warren Buffett could buy 254,503,480 gold rings. That's a lot of fingers and a lot of gifts!!
And if the number of rings is difficult to visualize, all these rings would need 45 trucks to transport them, But we can be almost certain that Warren Buffett will have enough left over to pay for the gas for those trucks.
Health
The price of life
Let's compare Warren Buffett's fortune with the healthcare spending of a huge country
Warren Buffett could fund the entire healthcare system of DR Congo with a population of over 105,800,000 of inhabitants for approximately 63.7 years.

But not only could he assume the cost of a poor country, Luxembourg is considered the country with the highest per capita investment in education in the world, Warren Buffett could pay for it in full for 56.6 years.
Research
The monopoly of progress
Lowest research spending
Warren Buffett could fully fund the state research budget of Pakistan, the fifth most populous country in the world with more than 260,000,000 of inhabitants, for 238.4 years.
Highest research spending
But even if we compare the total wealth of Warren Buffett with Israel, the country that currently invests the most per capita in research in the world, it could assume the total cost of the system for 5.3 years.
