How to use
- For each course, choose your letter grade and enter its credits (credit hours or units).
- Need more than four courses? Open More courses.
- For a cumulative GPA (CGPA), open the cumulative section and add your previous GPA and the credits it covers.
- Pick whether A+ is worth 4.0 or 4.3 at your school.
GPA formula
GPA = Σ (grade points × credits) ÷ Σ credits
- Quality points for a course = grade points × credits.
- Cumulative GPA = (previous GPA × previous credits + this term’s quality points) ÷ all credits.
Never average two GPAs directly. A term with more credits should count for more.
Example
| Course | Grade | Credits | Quality points |
|---|---|---|---|
| 1 | A (4.0) | 3 | 12 |
| 2 | B+ (3.3) | 3 | 9.9 |
| 3 | A− (3.7) | 4 | 14.8 |
| 4 | B (3.0) | 3 | 9 |
That is 45.7 quality points over 13 credits: 45.7 ÷ 13 = 3.52.
With a previous GPA of 3.20 over 30 credits, the cumulative GPA is (96 + 45.7) ÷ 43 = 3.30.
Grade points on the 4.0 scale
| Grade | Points |
|---|---|
| A+ | 4.0 (4.3 at some schools) |
| A | 4.0 |
| A− | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B− | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C− | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| D− | 0.7 |
| F | 0.0 |
Why your school's GPA may differ
- Some universities use thirds, such as 3.67 for A− and 3.33 for B+ (University of Nebraska–Lincoln).
- Some have no A+ or D− (North Carolina A&T).
- Most report GPA to 2 decimals; some use 3.
- Pass/fail, withdrawn and incomplete courses usually don’t count.
Your registrar’s figure is always the official one.
