Which CGPA to Percentage Formula Should I Use?
Use your university’s published formula if it has one. Use CGPA × 9.5 only as an estimate when no official rule applies.
| University or board | Formula | 8.0 CGPA becomes |
|---|---|---|
| VTU (2022 scheme onwards) | CGPA × 10 | 8.0 → 80.00% |
| VTU (2015, 2017, 2018 schemes) | (CGPA − 0.75) × 10 | 8.0 → 72.50% |
| GTU | (CPI − 0.5) × 10 | 8.0 → 75.00% |
| Anna University (University Departments, R-2015/18/19) | CGPA × 10 | 8.0 → 80.00% |
| CBSE Class 10 (historical CCE scheme) | CGPA × 9.5 | 8.0 → 76.00% |
Each university page cites the official notice or regulation behind its formula. For why the numbers differ so much, read why your CGPA-to-percentage conversion depends on which university you ask.
The ×9.5 Formula
Percentage = CGPA × 9.5
Example: 8.5 CGPA × 9.5 = 80.75%.
The 9.5 multiplier comes from historical CBSE Class 10 CCE guidance. Many employers and portals still accept it when no other rule is given, but it is not an official university formula.

Frequently Asked Questions
How do I convert CGPA to percentage?
On a 10-point scale, the most widely used estimate is Percentage = CGPA × 9.5, so an 8.0 CGPA is 76%. If your university publishes its own formula, use that instead: for example VTU uses CGPA × 10 for the 2022 scheme and GTU uses (CPI − 0.5) × 10.
What is 8 CGPA in percentage?
Using the common ×9.5 rule, 8.0 CGPA is 76%. Under university-specific formulas the same CGPA gives 80% at VTU (2022 scheme) and Anna University Departments, 75% at GTU, and 72.5% under the older VTU (CGPA − 0.75) × 10 formula.
Where does the ×9.5 multiplier come from?
It comes from historical CBSE Class 10 CCE guidance, where 9.5 was the average ratio between marks and grade points. It was never a universal university rule, and CBSE’s own 2023 guidance says the Board does not calculate an overall percentage. Treat ×9.5 as an estimate unless your institution prescribes it.
Can I use this for a 4.0 GPA?
No. The ×9.5 rule and the university formulas on this page are for 10-point CGPA only. For a 4.0, 5.0 or 7.0 scale, use the GPA to Percentage Converter, which applies proportional rescaling: (GPA ÷ scale) × 100.
Which percentage should I write on a job or admission form?
Use the formula printed on your grade card or published in your university’s regulations. If the form names a formula, use that one. Only fall back to ×9.5 when neither your university nor the form specifies a method, and say which formula you used.
