Master's degree: Typically takes one to two years of full-time study beyond a bachelor's degree.
Ph.D.: Typically takes four to eight years of full-time study beyond a bachelor's degree.
So, the total time to get a bachelor's, master's, and Ph.D. could be anywhere from nine to fourteen years of full-time study.
Of course, these are just general guidelines. The actual time it takes to complete each degree can vary depending on the individual student, the institution, and the specific field of study.
