The Numbers to CGPA Calculator converts raw numerical marks into a weighted CGPA and letter grade instantly. Enter the marks you obtained in each subject along with the total marks and credit hours, choose your grading scale (4.0, 5.0, or 10.0), and the calculator computes the grade point for each subject and then combines them into a single CGPA using the standard weighted formula: CGPA = Σ(Grade Points × Credit Hours) ÷ Σ(Credit Hours).

| 97–100 | A+ | 4.0 | 5.0 | — |
| 93–96 | A | 4.0 | 4.7 | — |
| 90–92 | A- | 3.7 | 4.3 | — |

| 87–89 | B+ | 3.3 | 4.0 | — |
| 83–86 | B | 3.0 | 3.7 | — |
| 80–82 | B- | 2.7 | 3.3 | — |
| 70–79 | A / B | — | — | 8.0 / 7.0 |
| 77–79 | C+ | 2.3 | 3.0 | — |

Enter all your semester marks to see your cumulative GPA and find out your academic standing before official results are published.
Convert your numerical transcript marks into a CGPA that admissions offices and graduate programs can evaluate directly.
Check whether your current marks translate into a CGPA that meets the minimum threshold (e.g. 3.5 / 4.0) for scholarships and honours programmes.
Enter your current marks and adjust them to see what scores you need in remaining subjects to hit a target CGPA.
Each subject's percentage is first converted to a grade point (e.g. 88% → B+ → 3.3 on a 4.0 scale). The CGPA is then the weighted average: CGPA = Σ(Grade Points × Credit Hours) ÷ Σ(Credit Hours). If all subjects have equal credits, it simplifies to the simple average of all grade points.
The 4.0 scale is used by most US and international universities where A = 4.0 is the maximum. The 10.0 scale is common in Indian and Pakistani institutions where O (Outstanding) = 10 is the highest grade. Both produce a CGPA that represents relative academic performance, but on different numerical ranges.
No — credit hours default to 3 if left blank. If all your subjects carry equal weight, you can leave the credits field empty and get a simple average. Enter actual credits for a more accurate weighted CGPA.
