About the GPA Calculator
What is the GPA Calculator?
Your grade point average weights each course's grade point by its credits. This gpa calculator accepts letter grades (O, A+, A … or A, A-, B+ …) or numeric grade points on either scale.
It gives the SGPA for a semester, the total credit points and an approximate percentage.
How to use the GPA Calculator
- Grading Scale (sample: 10-point (O, A+, A, B+, B, C, P, F – UGC CBCS))
- Courses (one per line: course, credits, grade letter or grade point) — one course per line: course name, credits, grade letter or grade point. For example: Mathematics, 4, A. (sample: Mathematics, 4, A Physics, 3, B+ Chemistry, 3, A+ Physics Lab, 2, O English, 2, A)
- Press Calculate GPA (results also refresh as you type). The result card shows the GPA / SGPA, along with Total credits, Total credit points, Approximate percentage and Percentage basis.
Formula used
GPA = Σ (Credits × Grade point) ÷ Σ Credits
- 10-point scale = O 10, A+ 9, A 8, B+ 7, B 6, C 5, P 4, F 0
- 4-point scale = A 4.0, A- 3.7, B+ 3.3, B 3.0, B- 2.7 … F 0
Failed courses (F) count with zero points until cleared, lowering the GPA.
Worked example
These are the sample values already filled in the calculator above, and the result it returns for them:
| Input | Sample value |
|---|---|
| Grading Scale | 10-point (O, A+, A, B+, B, C, P, F – UGC CBCS) |
| Courses (one per line: course, credits, grade letter or grade point) | Mathematics, 4, A Physics, 3, B+ Chemistry, 3, A+ Physics Lab, 2, O English, 2, A |
| Result | Value |
|---|---|
| GPA / SGPA | 8.29 |
| Total credits | 14 |
| Total credit points | 116 |
| Approximate percentage | 78.71% |
| Percentage basis | CGPA × 9.5 (CBSE convention); your university may use its own formula |
UGC 10-point grading scale
| Letter grade | Grade point (10-point) | Typical marks |
|---|---|---|
| O (Outstanding) | 10 | 90–100 |
| A+ (Excellent) | 9 | 80–89 |
| A (Very good) | 8 | 70–79 |
| B+ (Good) | 7 | 60–69 |
| B (Above average) | 6 | 55–59 |
| C (Average) | 5 | 50–54 |
| P (Pass) | 4 | 40–49 |
| F (Fail) | 0 | Below 40 |
UGC's choice-based credit system uses these letter grades; the marks bands vary between universities.
Tips for using the GPA Calculator
- High-credit courses move your GPA the most – prioritise them.
- Check your university's grade-point table, as bands differ.
