Warren Buffett IQ — estimated score & cognitive profile
Warren Buffett's IQ is estimated at 150. This is a widely-cited estimate based on Warren Buffett's body of work and historical accounts — not a verified, administered psychometric test score. An IQ of 150 would place a person in the top 0.04% of the population (roughly 1 in 2,331).
Important note: Most famous-person IQ figures are estimates, retroactive assessments, or based on childhood tests not directly comparable to adult standardised IQ. We present these as historically reported estimates — not verified psychometric measurements.
Buffett has never released an IQ score but is estimated to be in the 145-155 range based on his ability to process complex financial data at scale and his exceptional verbal reasoning in writing and speaking. He scored the highest on a standardised test for entering his MBA at Columbia at age 19.
What IQ 150 means
→Pause. Find out YOUR IQ before you keep reading.An IQ of 150 — if accurate — would place Warren Buffett in the Highly gifted range, scoring higher than an estimated 99.96% of the adult population. Scores above 145 occur in roughly 1 in 1,000 people; scores at 150 are far rarer (about 1 in 2,331).
The limits of IQ estimates for famous people
→Curious how YOU score? 20-min calibrated test.Famous-person IQ estimates circulate widely online but are often unreliable:
- Many historical figures (Einstein, Newton) never took any IQ test — scores are extrapolated from their work, not measured
- Childhood ratio-IQ tests (which divided mental age by chronological age) produce inflated numbers not comparable to adult deviation IQ scores
- Reported scores are often laundered through celebrity media without primary sources
- Very high scores (above 160-170) have measurement precision issues even on the best adult tests — the tail of the distribution is hard to measure accurately
High IQ doesn't guarantee success (and vice versa)
→The numbers above? Find out where YOU land.The most instructive case here is Richard Feynman, who reportedly scored 125 on his high-school IQ test — not exceptional — and went on to win the Nobel Prize in Physics. As Feynman himself noted, the test measures a specific kind of reasoning, not the full spectrum of ability required to make world-changing scientific contributions.
What the highest-IQ people tend to share is:
- Exceptional working memory — holding many variables in mind simultaneously
- Speed of abstract reasoning — recognising patterns and relationships quickly
- Deep focus on topics that interest them
- Willingness to persist through difficult problems
Other famous IQs
→Knowing about IQ ≠ knowing yours. Take the test.- Elon Musk — estimated IQ 155
- Albert Einstein — estimated IQ 160
- Stephen Hawking — estimated IQ 160
- Nikola Tesla — estimated IQ 160
- Bill Gates — estimated IQ 160
Frequently asked about Warren Buffett's IQ

Is Warren Buffett's IQ score reliable?
Treat it as suggestive, not definitive. Famous-person IQ figures are often extrapolated from achievements, childhood ratio-IQ tests, or unsourced media claims, none of which are directly comparable to a modern administered adult IQ test.
