Your GPA (grade point average) is the credit-weighted average of your grade points. Convert each letter grade to points on the 4.0 scale (A = 4.0, B = 3.0, C = 2.0, and so on), multiply each by the course's credit hours to get quality points, add up the quality points and the credit hours, then divide total quality points by total credit hours. For B (3 credits), A- (4), C (2) and C (3) that is 33.68 quality points over 12 credit hours — a GPA of about 2.81.

How it works
A GPA is a weighted mean: courses worth more credit hours count more. Per the Rice University registrar, the steps are:
- Convert each letter grade to its grade points on the 4.0 scale (below).
- Multiply each course's grade points by its credit hours — that is the course's quality points.
- Add up the quality points for all courses, and separately add up the credit hours.
- Divide total quality points by total credit hours. That is your GPA:
GPA = Σ(grade points × credit hours) ÷ Σ(credit hours)
The 4.0 grade-point scale
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ | 4.00 | C | 2.00 |
| A | 4.00 | C- | 1.67 |
| A- | 3.67 | D+ | 1.33 |
| B+ | 3.33 | D | 1.00 |
| B | 3.00 | D- | 0.67 |
| B- | 2.67 | F | 0.00 |
| C+ | 2.33 |
Grades that carry no grade points — Pass/Fail, Withdraw, Incomplete — are left out of the GPA, so omit those courses. Enter a failing grade as F (0 points). Scales vary between schools (some cap A+ at 4.00, as here; some weight honors or AP courses higher); this calculator uses the standard unweighted US 4.0 scale.
Worked example
Take four courses: B (3 credits), A- (4), C (2) and C (3). On the 4.0 scale those are 3.00, 3.67, 2.00 and 2.00 grade points. Multiplying by credit hours gives quality points of 3.00 × 3 = 9.00, 3.67 × 4 = 14.68, 2.00 × 2 = 4.00 and 2.00 × 3 = 6.00 — a total of 33.68 quality points over 12 credit hours. Dividing, 33.68 ÷ 12 = 2.806, or about 2.81.

How is GPA calculated?
- Convert each letter grade to grade points on the 4.0 scale, multiply each by the course's credit hours to get quality points, total the quality points and the credit hours, then divide the total quality points by the total credit hours.
How do I convert letter grades to grade points?
- Use the 4.0 scale: A and A+ are 4.0, A- is 3.67, B+ is 3.33, B is 3.0, and so on down to D- at 0.67 and F at 0.0. A plus adds about a third of a point and a minus subtracts about a third.
What is the difference between a weighted and an unweighted GPA?
- An unweighted GPA puts every course on the same 4.0 scale, as this calculator does. A weighted GPA gives extra points to harder courses — an A in an AP or honors class might be worth 5.0 instead of 4.0 — so a weighted GPA can rise above 4.0.
How do credit hours change my GPA?
- Because the GPA is credit-weighted, a grade in a 4-credit course moves it more than the same grade in a 1-credit course. That is why quality points (grade points × credit hours) are summed before dividing, rather than simply averaging the letter grades.
How do I calculate a cumulative GPA across several semesters?
- List every graded course from all semesters together — all the grades in one box and all the matching credit hours in the other. The credit weighting then combines the terms correctly; you cannot simply average the individual semester GPAs unless every semester carried the same number of credits.
Do Pass/Fail or withdrawn courses count toward GPA?
- No. Courses graded Pass/Fail, Credit/No-Credit, Withdraw, or Incomplete carry no grade points, so they are excluded from the GPA. Leave them out of the grades and credits.
