The average retirement age for a doctor is about 65 years for male physicians, and female doctors often retire sooner than males, reports the Houston Chronicle. The average retirement age for internists was 62 in 2002 and 70 in 2009. By age 75, 80 percent of male doctors have retired.
A physician's projected work life lasts approximately 35 years after completing residency, according to the Houston Chronicle. Doctors may end their practices to assume administrative positions in which they utilize their medical knowledge, such as becoming insurance consultants or medical directors. Physicians may continue to work longer due to economic conditions. Since 2006, 18 percent fewer doctors have reported satisfaction with retirement plans.
