GPA Calculator

How to calculate your GPA

1. Pick a Grading scale (example): US 4.0, A–F with +/−, US 4.0, A–F without +/− or Canada 4.33 (example).
2. Add one row per course with its Grade and Credits. A grade can be a letter (A-, B+) or a percentage (88), which is converted to a letter with the chosen scale.
3. Use Add a course for more rows and × to remove one.
4. For your overall GPA, fill in Cumulative GPA (optional) with your GPA so far and the Credits so far it covers.
5. Read the Term GPA, the Credits, the Grade points and the Cumulative GPA. The calculation for every course appears below.

Open Show the scale to see the percentage range and grade points of each letter on the selected scale.

How GPA is calculated

GPA (grade point average) is a credit-weighted average of grade points. Each letter grade is worth a number of points (A = 4.0, B = 3.0, and so on). A course’s quality points are its grade points multiplied by its credits:

GPA = Σ (grade points × credits) ÷ Σ credits

Example: A− (3.7) in a 3-credit course, 88% (B+, 3.3) in a 3-credit course and B (3.0) in a 4-credit course give 11.1 + 9.9 + 12 = 33 quality points for 10 credits, a term GPA of 3.30.

Cumulative GPA

Your cumulative GPA combines every term. Multiply your previous GPA by the credits it covers to get your previous quality points, add this term’s, and divide by all credits:

Cumulative GPA = (previous GPA × previous credits + term quality points) ÷ (previous credits + term credits)

With a 3.0 GPA over 45 credits and a 4.0 term over 15 credits: (135 + 60) ÷ 60 = 3.25. Notice how the weight of past credits makes a cumulative GPA move slowly.

The scales

• US 4.0 with +/−: A and A+ = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, and so on down to D− = 0.7 and F = 0. The percentage cut-offs (93% for an A, 90% for an A−…) are the common 10-point bands.
• US 4.0 without +/−: A = 4, B = 3, C = 2, D = 1, F = 0, with 90/80/70/60% cut-offs.
• Canada 4.33: some Canadian universities give an A+ 4.33 points, A 4.0, A− 3.67 and so on. Canadian schools use many other scales too (4.0, 9-point, 12-point or percentages).

All three are examples. Institutions set their own cut-offs, their own value for an A+, and their own rules for repeated courses, withdrawals and pass/fail courses. Other systems, such as Québec’s cote R used for university admission, work very differently and are not covered here. Always treat your official transcript as the reference.
