How the Cumulative GPA Calculator Works
Your cumulative GPA combines all your coursework across semesters. This calculator takes your existing GPA and completed credits, then adds your new semester\u2019s courses to calculate your overall cumulative GPA and the GPA for your new semester separately.
The Formula
Cumulative GPA = (Existing GPA × Existing Credits + New Grade Points) / (Existing Credits + New Credits)
New Semester GPA = New Grade Points / New Credits
Where new grade points are calculated by summing (grade points × credits) for each new course.
Worked Example
Scenario
Sarah has a 3.2 GPA after completing 30 credits. This semester, she takes two courses: Biology (B, 3 credits) and Chemistry (A-, 4 credits).
Calculation:
- Existing total points: 3.2 × 30 = 96.0
- Biology: 3.0 × 3 = 9.0
- Chemistry: 3.7 × 4 = 14.8
- New total: 9.0 + 14.8 = 23.8 points (7 credits)
- New semester GPA: 23.8 / 7 = 3.40
- Cumulative GPA: (96.0 + 23.8) / (30 + 7) = 119.8 / 37 = 3.24
Interpreting Your Results
The calculator shows both your new semester GPA and your overall cumulative GPA. If your new semester GPA is higher than your existing GPA, your cumulative GPA will increase; if lower, it will decrease. The more credits you\u2019ve already completed, the harder it is to significantly change your cumulative GPA with one semester.
Frequently Asked Questions
Why won\u2019t my cumulative GPA change much?
If you\u2019ve completed many credits already, a single semester has less impact on your cumulative GPA. For example, a 4.0 semester with 15 credits will raise a 3.0 GPA more if you\u2019ve completed 30 credits than if you\u2019ve completed 90 credits.
Can I use this for transfer credits?
Yes. Enter the GPA from your previous institution as the existing GPA and the number of transfer credits accepted. Add your new courses from your current institution.
What if I\u2019m just starting (0 existing credits)?
Enter 0 for existing credits and your cumulative GPA will equal your new semester GPA.
