How Would John D. Rockefeller Have A Net Worth Of $418 Billion If He Were Alive Today?

John D. Rockefeller is considered the richest man in history. In his peak, John D. Rockefeller would have had an estimated net worth of $418 billion in 2022 (adjusted for inflation).

Rockefeller was an American business magnate, philanthropist, and entrepreneur. He amassed most of his fortune from his company the Standard Oil Company, which he founded in 1870. As gasoline and kerosene grew in popularity through the late 1800s and early 1900s so did his net worth.

In this article, we will discuss how John D Rockefeller became the richest man ever. We will also adjust his net worth for inflation to see how much he would be worth if he were alive today. Update: He was surpassed by Elon Musk in 2021.

Early Life

John D. Rockefeller was born in Richford, New York on July 8th, 1839. He was the second child of Bill Rockefeller and Eliza Davidson. His mother Eliza was a Baptist and his father was a businessman, and salesman, but most notably, a con artist.

He self-identified as a “botanic physician” where he would sell elixirs that could cure various ailments. Bill didn’t have a strong moral compass as he also rarely stayed with his family and was rumored to have married another woman while still married to Rockefellers’ mom.

Rockefeller learned important lessons from both his parents growing up. His dad would try to cheat Rockefeller every chance he got in an effort to “keep him sharp.” His mother, trying to keep stability in her household, taught Rockefeller that reckless extravagance leads to a dire need for more.

When Rockefeller was sixteen, he got his first job as an assistant bookkeeper where he first discovered that he was adept at calculating transportation costs.

Although he never made more than $58 dollars a year working as a bookkeeper, Rockefeller has said that he knew one day he would make $100,000 (equivalent to $2.74 million dollars in 2022).

Clark & Rockefeller

In 1859, at the age of 20, John D. Rockefeller went into the business of produce commission (buying or selling perishable agricultural goods) with partner Maurice B. Clark. In their first year of business, Clark & Rockefeller netted $4,400. In their second year, they nearly quadrupled their net income to $17,000 (equivalent to $530,688 dollars in 2022).

Their profits only went up from there as the start of the American Civil War led to a massive increase in demand for food supplies. When the Civil War was coming to a close and the war-time profits were slowing down Clark & Rockefeller looked toward the refining of crude oil.

Standard Oil Co.

John D. Rockefeller also saw a market emerging for refined oil in the form of kerosene. Coal had previously been used to extract kerosene, but it was inefficient. However, even with all of its inefficiencies, the current mark-up on refined oil was anywhere from 62% to 160%. This led him to start his own company, Standard Oil Co in 1870.

Many speculators attempted to make their fortunes through oil, but most were unsuccessful. This was mainly due to the fact that most refineries would keep the 60% of oil product that became kerosene, but dump the other 40% in rivers and massive sludge piles. Rockefeller cleverly avoided that waste by selling it as lubricating oil, petroleum jelly, paraffin wax, tar, and other by-products.

Rockefeller quickly grew the company by acquiring the least efficient competing refiners, improving its operations, getting bulk discounts on oil shipments, dropping its prices, and raising investment pools.

By 1872, Rockefeller had purchased 22 of its 26 Cleveland, Ohio competitors. Standard Oil wasn’t just acquiring its competition, it also acquired its entire supply chain. It added its own pipelines, tank cars, and home delivery network.

Because they produced such a large quantity of oil they were able to keep their prices low which deterred competitors while also making their products affordable to the average person. By the end of the 1870s, Standard Oil was responsible for refining over 90% of U.S. oil, and Rockefeller was a multi-millionaire.


Since Rockefeller controlled over 90% of the oil industry, journalists and politicians constantly attacked Standard Oil as having unfair monopolistic practices. Unfair practices like these are what led to the passing of Antitrust laws and the creation of the Federal Trade Commission (FTC). He retired in 1902 at the age of 63.

John D. Rockefeller Net Worth 2022

How much would John D. Rockefeller be worth now? Well, in full retirement at age 63, Rockefeller earned over $58 million in investments in 1902 (just over $1.7 billion dollars in 2022).

At his peak in 1913, John D. Rockefeller had an estimated net worth of $418 billion dollars (adjusted for inflation in 2022). His personal wealth at the time was estimated at $900 million in 1913, which was almost 3% of the US GDP that year.

Key Takeaways

  • You can pave your own destiny: John D. Rockefeller was born to a well-known con artist. He easily could have gone down a similar path but instead decided to have a strong moral code and marry only once. We can’t choose our family, but we are in complete control of our destiny.
  • There is never a lack of resources, just resourcefulness: Many entrepreneurs failed to take advantage of the growing oil market because they had to get rid of 40% of all the materials they would mine. Instead of wasting this 40%, Rockefeller decided to sell the perceived waste to companies that would need it.
  • Spotting opportunity and taking action: Just as Mr. Wonderful saw that computers and software would end up becoming a booming business in the 1990s, Rockefeller saw that refined oil in the form of kerosene would explode going into the 1900s. Rockefeller had no prior experience in oil manufacturing before starting Standard Oil. Most entrepreneurs teach themselves how to do things by taking action, not by studying. If Rockefeller waited to learn more about the oil industry before starting, he may have missed his opportunity.
