How many years does it take to get a PhD in the USA? What is the typical time to degree? I heard a rumor it was five years.
For US PhD recipients in 2018, the median years between starting graduate school and earning a doctorate was 7.3. Completing a PhD in five years has been done many times, but most PhD students will not do it and five years is not typical.
Statistics do not include PhD students who never receive a PhD.
There is large variation based on discipline and race: https://ncses.nsf.gov/pubs/nsf20301/assets/data-tables/tables/nsf20301-tab031.pdf https://ncses.nsf.gov/pubs/nsf20301/assets/data-tables/tables/nsf20301-tab032.pdf
