How to use the GPA Calculator

- To update a cumulative GPA, open “Add previous semesters” and enter your current GPA and credits.
What does this tool do?
GPA (grade point average) is a credit-weighted average: each course's grade points are multiplied by its credit hours, added up, and divided by the total credits. A 4-credit course affects your GPA more than a 1-credit one.
On the common 4.0 scale an A is 4.0, a B is 3.0 and so on, with plus and minus grades in between. Some schools give an A+ 4.3.
Why use it?
- Plan which grades you need for scholarships or honors.
- Check your transcript math.
- Combine this semester with your cumulative record.
Example
English (A, 3 credits), Calculus (B+, 4 credits), Biology (A−, 4 credits) and History (B, 3 credits): grade points = 12 + 13.2 + 14.8 + 9 = 49. Divide by 14 credits and the GPA is 3.50.
| Letter | 4.0 scale | Typical % |
|---|---|---|
| A | 4.0 | 93–100 |
| A− | 3.7 | 90–92 |
| B+ | 3.3 | 87–89 |
| B | 3.0 | 83–86 |
| B− | 2.7 | 80–82 |
| C+ | 2.3 | 77–79 |
| C | 2.0 | 73–76 |
| D | 1.0 | 63–66 |
| F | 0.0 | Below 60 |

Frequently asked questions
Do pass/fail courses count toward GPA?
Usually not. They earn credits but have no grade points, so leave them out of the calculation.
