Overall, 91.4% of MIT Undergrads Finish Within Six Years
At MIT, there were 1,059 bachelors degree candidates in the class of 2012. By 2014, six years after beginning their degree, 91.4% of these students had graduated. After an additional two years, 93.2% of this class eventually completed their degree.
We consider the "on-time" graduation rate for a bachelor's degree to be four years, but colleges typically report their graduation rates after six or even eight years.
