GPA Calculator

This calculator can be used for you to plan your quarter goals and also to project your new Cal Poly GPA when you are repeating a course. Do remember that this is an unofficial tool, only as accurate as the information you enter!

Calculate your GPA for the current quarter only (and without repeats)

  • Leave the Current Cumulative GPA table blank.
  • Enter the name, number of units, and your projected grade range in each course. Note that the "grade range" are the high and low grades you anticipate for each course; e.g., if you have a B in a class and the final is worth a good portion of your grade, you may decide that a range of between A and C+ is possible for your grade.
  • After you enter a unit count and a grade range for each class, your GPA estimates will be displayed in the "Total High & Low GPA" table, under GPA High and GPA Low.
Calculate your GPA for the current quarter (with repeats)

  • Enter in your total graded units and current cumulative GPA in the "Current Cumulative GPA" table.
  • Click the "Show Repeats" button.
  • Then select the check box under the "Repeating Class?" Column.
  • Select the previous grade you received in the class you are repeating.
  • The calculator will adjust your GPA and unit count accordingly to show your new projected total GPA.

Note: This GPA calculator is intended to be used as a tool, not as an official indication of your Cal Poly GPA. This calculator should be used for planning purposes only and its accuracy is not guaranteed. Be sure to check:

  • Your department’s rules regarding grade expectations in classes and for continuation at the university.
  • University policies regarding change of grade and repeat units:
    • An individual course grade can be replaced (with a repeated course) only one time during your entire undergraduate education at Cal Poly.
    • Only 16 units total can be repeated and replaced.
    • Once the 16 unit threshold is reached, other repeated units are added into the total, not replaced.
