How to convert CGPA to percentage
Updated: 28 October 2026
CGPA (Cumulative Grade Point Average) is the average of your grade points across all subjects or semesters, usually on a 10-point scale. There is no single conversion that works everywhere: each board or university decides how a CGPA maps to a percentage. Use the rule your institution publishes.
CBSE: multiply by 9.5
CBSE introduced the 9.5 factor for the CGPA (CCE) system. It came from the average marks of students who scored a perfect 10 CGPA in earlier years, so it is an indicative figure rather than an exact one. A CGPA of 8.6 gives 8.6 × 9.5 = 81.7%.
Common university formulas
| Board / University | Formula | CGPA 8.0 becomes |
|---|---|---|
| CBSE | CGPA × 9.5 | 76% |
| Anna University | CGPA × 10 | 80% |
| VTU (Karnataka) | (CGPA − 0.75) × 10 | 72.5% |
| GTU (Gujarat) | (CGPA − 0.5) × 10 | 75% |
| 4-point GPA (US style) | GPA ÷ 4 × 100 (estimate) | 3.2 GPA ≈ 80% |
If your university is not listed, look at the back of your marksheet or the academic regulations on the university website. Most give the formula in the form (CGPA − a) × b, which you can enter using the Custom option above.
Percentage to CGPA
To go the other way, reverse the formula. Under the CBSE rule, CGPA = Percentage ÷ 9.5, so 76% is 8.0 CGPA. For VTU, CGPA = Percentage ÷ 10 + 0.75. Switch the calculator to Percentage → CGPA and it does this for whichever rule you pick.
CBSE CGPA to percentage table
| CGPA | Percentage | CGPA | Percentage |
|---|---|---|---|
| 10.0 | 95% | 7.5 | 71.25% |
| 9.5 | 90.25% | 7.0 | 66.5% |
| 9.0 | 85.5% | 6.5 | 61.75% |
| 8.5 | 80.75% | 6.0 | 57% |
| 8.0 | 76% | 5.0 | 47.5% |
Values use CGPA × 9.5. A perfect 10 CGPA shows as 95% under this rule, not 100%.
