What is cumulative GPA?
Your cumulative GPA is your overall grade point average across every semester you have completed, weighted by credit hours. A 4-credit A counts twice as much as a 2-credit A. It is not the average of your semester GPAs, because semesters with more credits count for more. Colleges usually show it on your transcript as “cumulative” or “overall” GPA.
Calculate your new GPA from your current GPA
You don’t need every old grade: your current GPA and credits are enough, which is how this GPA calculator using current GPA works. New GPA = (current GPA × current credits + semester GPA × semester credits) ÷ total credits. Example: you have a 3.10 GPA after 60 credits and earn a 3.60 in a 15-credit semester. (3.10 × 60 + 3.60 × 15) ÷ 75 = 240 ÷ 75 = 3.20. Going the other way, to reach a 3.30 you would need a 4.10 over the next 15 credits, which isn’t possible on a cumulative GPA 4.0 scale, or a 3.70 over the next 30 credits. That is why a GPA moves more slowly the more credits you have. Some universities call this figure CGPA; the GPA calculator CGPA method is the same.
Overall GPA calculator: your GPA after this semester
Enter your current cumulative GPA and the credits behind it, then add this semester. The calculator weights each term by its credits and shows your new overall GPA, plus the GPA you would need next term to reach a target.
How to calculate cumulative GPA
Cumulative GPA is not the average of your semester GPAs. Each term counts in proportion to its credits, so a 15-credit semester moves your GPA more than a 6-credit summer term. Enter your current cumulative GPA with the credits it covers, then add each new semester with its GPA and credits.
Cumulative GPA formula
Cumulative GPA = (GPA₁ × Credits₁ + GPA₂ × Credits₂ + …) ÷ (Credits₁ + Credits₂ + …)
GPA needed next term = (Target × (Completed + Next credits) − Current GPA × Completed) ÷ Next credits
Example: a 3.2 GPA after 45 credits plus a 3.6 semester
Quality points so far are 3.2 × 45 = 144. The new 15-credit semester adds 3.6 × 15 = 54. Your cumulative GPA is (144 + 54) ÷ 60 = 3.30. A great semester raises the total, but by less than many students expect, because the earlier 45 credits still count three times as much.
How much one semester can move your GPA
| Credits completed | Current GPA | Next 15 credits at | New cumulative GPA |
|---|---|---|---|
| 15 | 3.00 | 4.00 | 3.50 |
| 30 | 3.00 | 4.00 | 3.33 |
| 60 | 3.00 | 4.00 | 3.20 |
| 90 | 3.00 | 4.00 | 3.14 |
Total GPA calculator: which credits count
Use the credits that count toward GPA. Pass/fail courses, withdrawals and transfer credit are often excluded from the GPA calculation even when they count toward graduation. Some schools replace a repeated course grade instead of averaging both attempts, so a retake can lift your GPA more than this model shows.
Ways to raise a cumulative GPA
- Take a heavier credit load in a term where you expect strong grades.
- Ask whether your school offers grade replacement for repeated courses.
- Use the target planner to see whether your goal needs one term or several.
- Focus first on high-credit courses, since they carry the most weight.
Semester and cumulative GPA calculator example: three semesters
Semester 1: 3.2 GPA × 15 credits = 48 points. Semester 2: 3.6 × 16 = 57.6. Semester 3: 2.9 × 15 = 43.5. Cumulative GPA = 149.1 ÷ 46 = 3.24.
Key terms explained
- Cumulative GPA
- Your overall GPA across every term, weighted by credits.
- Quality points
- GPA multiplied by credits; they add up across semesters.
- GPA-bearing credits
- Credits that count in the GPA, usually excluding pass/fail and withdrawals.
