Every school recalculates your GPA differently. These 17 calculators use the real grading scale and weighting rules of each university or system — not a generic 4.0 formula.
A GPA is not a universal number. A 3.5 at one institution can describe a completely different level of performance from a 3.5 somewhere else, because the underlying grade points, the scales and the weighting rules all differ.
Three things change the answer most often. First, the scale itself: MIT uses a 5.0 scale, York a 9-point scale, McMaster 12 points, HKU 4.3, Bocconi 30, Bangladesh boards 5.00. Second, what counts: the UC system ignores 9th and 12th grade, UGA counts only the five core subject areas, and LSAC counts every attempt of a repeated course. Third, how courses are weighted: MIT and Bocconi weight by units or CFU, while GEMSAS weights your final year three times as heavily as your first.
Each page below shows the published grade table, the formula, a worked example and the rules that quietly move the number. Enter your own courses and you get the figure that school would actually calculate.
