About the Cumulative GPA Calculator
Your cumulative GPA is the credit-weighted average of every grade you have earned. This calculator takes your current cumulative GPA and credits completed, adds the courses you are taking this semester, and shows your new cumulative GPA and semester GPA on the standard 4.0 scale (A = 4.0, A- = 3.7, B+ = 3.3 and so on).
For a single semester or a "what grade do I need" question, see the GPA calculator and the final grade calculator.
How to use it
- Enter your current cumulative GPA and the credits you have completed.
- Pick the expected grade and credit hours for each course this semester (add more rows if needed).
- Press Calculate to see your new cumulative GPA and semester GPA.
Cumulative GPA formula
Cumulative GPA = (current GPA × completed credits + Σ(grade points × credits of new courses)) ÷ (completed credits + new credits).
Example: a 3.20 GPA after 45 credits, plus 13 credits at an average of 3.7 this semester, gives (3.20 × 45 + 3.7 × 13) ÷ 58 ≈ 3.31.
Letter grade to grade points (4.0 scale)

| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| D | 1.0 |

Frequently asked questions
How do I calculate my cumulative GPA?
Multiply your current GPA by credits completed, add the grade points from your new courses (grade value × credits), and divide by total credits.
What is the difference between GPA and cumulative GPA?
GPA can refer to one semester. Cumulative GPA averages all semesters, weighted by credit hours.
Can I raise a low cumulative GPA quickly?
The more credits you have completed, the slower it moves. Try different grade combinations above to see what you need.
Does this work for weighted (honors/AP) GPA?
This tool uses the unweighted 4.0 scale. Some schools add a bonus point for honors or AP, so follow your school policy.
Do pass/fail credits count?
Usually not in GPA. Leave those courses out.
