How to use the GPA Calculator

  1. 1Choose the grading scale your institution uses.
  2. 2Add a row for each course with its credit hours and the grade you received.
  3. 3Add or remove rows as needed — the GPA updates as you go.
  4. 4Courses graded pass/fail can be marked as excluded so they do not affect the average.

How it works

A GPA is a weighted mean, not a simple average. Each course's grade points are multiplied by its credit hours, those products are added up, and the total is divided by the total credits attempted. A five-credit course therefore moves your GPA more than a two-credit one.

The scale you choose determines what each letter is worth. On the common 4.0 scale an A is 4.0 and a B is 3.0; the 4.3 scale adds an A+ at 4.3; and the 5.0 scale is used where honours or AP courses carry extra weight. You can also type grade points directly if your institution publishes them.

Pass/fail and audited courses are normally excluded from the calculation entirely — they earn credit but carry no grade points — which is why marking them excluded removes their credits from the denominator as well.

The formula

GPA = Σ (grade points × credits) ÷ Σ credits
grade points
the numeric value of the letter grade on your scale
credits
the credit hours, units or weight of the course
Σ
the sum across every graded course

Excluded pass/fail courses are left out of both sums.

Worked example

Four courses in one semester on a 4.0 scale

  1. Biology, 4 credits, grade A (4.0) → 16.0 points
  2. History, 3 credits, grade B+ (3.3) → 9.9 points
  3. Maths, 4 credits, grade B (3.0) → 12.0 points
  4. Art, 2 credits, grade A− (3.7) → 7.4 points

Result: 45.3 total points ÷ 13 credits = a GPA of 3.48.

Frequently asked questions

What is the difference between GPA and CGPA?
GPA usually covers one term; CGPA is the cumulative figure across every term so far. Use the CGPA calculator to combine several semesters.
Do pass/fail courses count?
At most institutions they do not affect the GPA. Mark them as excluded and they are removed from both the points and the credits.
Why does one bad grade in a big course hurt so much?
Because credits are weights. A poor grade in a five-credit course carries more than twice the influence of the same grade in a two-credit course.
Which scale should I choose?
Whichever your institution publishes. If your transcript shows an A+ worth more than 4.0, choose 4.3 or 5.0; otherwise the standard 4.0 scale is right.
