Founder IQ estimate
Updated by TestYourIQ Research Desk. This page summarizes public evidence and treats celebrity IQ figures as estimates unless an official score is publicly documented.
What is Bill Gates's IQ?
Bill Gates's IQ is widely estimated at around 160, placing him in the rare upper tail associated with exceptionally strong abstract and mathematical reasoning.
Like most founder IQ pages, the claim is best treated as an estimate rather than a public official score.
Why is the estimate so high?
The supporting case usually points to Gates's SAT performance, early software ability, Harvard admission, and decades-long reputation for unusually fast and structured thinking.
- He built serious programming skills at a very young age.
- He entered Harvard before leaving to build Microsoft.
- Peers and biographers consistently describe him as exceptionally analytical.
Bottom line
A careful summary is that Bill Gates's IQ is commonly estimated around 160, with strong indirect evidence but no public official score sheet.
