Grade Calculator


College students can calculate overall grade of courses they take by using this simple and practical grade calculator. Also, students can calculate average overall grade (curve) and compare it to their grade. If you like, you can enter an estimated curve value to find out your approximate letter grade under the curve-based grading system, assuming CC, C, or C2 as the curve threshold.





Note: When calculating according to the curve, it is assumed that letter grades increase or decrease in increments of 5 points similarly to the catalog system. In reality, the curve letter grade and the ranges for other letter grades may vary depending on the course, department, or instructor. For example, the instructor might set the curve threshold at DD (often seen in cases of low averages), which in turn changes the ranges for other letter grades. We use a basic approach here, so please keep this in mind.

Instructions - Grade Calculator

Usage of this grade calculator is simple.

  • You should just enter grade(s) of midterm(s) of courses and their percentages.

  • Then enter final grade of the course. Others may refer to projects, homeworks, quizzes etc.

  • You can use + button in order to increase number of others or midterm.

  • If you would like to see your approximate letter grade according to the curve, you can also enter an estimated curve value (the total score you obtained from all exams, assignments, etc.). If you only want to know your letter grade based on the catalog grading system, there is no need to enter a curve value.

  • Finally, just click calculate button to calculate your estimated overall grade.

Example - Grade Calculator

Suppose that we take a course which has two midterms, one final exam and one term project.

Let their percentages be 20, 20, 40, 20 respectively.

Let Midterm 1 = 86, Midterm 2 = 84, Final = 70, Project = 90

Then our overall grade would be 80. This grade may vary according to the university and lectures, and may correspond to different letter grades. A score that corresponds to BB in the catalog system could become AA when the curve is applied. For instance, if 60 points is considered equivalent to CC under the curve, your BB-level score might shift up to AA.
