The Formula: Why 9.5 and Not 10?
CGPA = Percentage ÷ 9.5
Example: 85% ÷ 9.5 = 8.9 CGPA
CBSE arrived at 9.5 by analysing the marks of students who scored the A1 grade (91–100 band) in previous board results. The average marks of A1 scorers worked out to roughly 95, so one grade point was equated to 9.5 percentage points — not 10. Dividing by 10 would understate the CGPA of nearly every student.

Does Every Board Use ÷ 9.5?
No — the 9.5 factor is a CBSE convention. Before using a converted figure on an application form, check which formula the receiving institution expects:
- CBSE (Class 10): Percentage ÷ 9.5
- Many universities (UGC pattern): some use (CGPA − 0.75) × 10 in reverse, or a straight ÷ 10 — the exact rule is printed on the degree/marksheet or the university's conversion certificate
- Engineering universities (e.g. VTU, AKTU): publish their own conversion formulas that differ from CBSE's
- ICSE: reports actual percentage; no official CGPA conversion exists
When a form asks for CGPA and your marksheet shows percentage, the safest answer is the one produced by the issuing board's own formula — for CBSE students, that is the ÷ 9.5 result this tool gives you.

Frequently Asked Questions
Divide your percentage by 9.5. For example, 76% ÷ 9.5 = 8.0 CGPA. This is the official CBSE relationship between marks and grade points.
80 ÷ 9.5 = 8.4 CGPA on the CBSE 10-point scale, which falls in the A2 grade band.
CBSE analysed results of students scoring in the 91–100 band (A1 grade) and found their average was about 95 marks. So one grade point was mapped to 9.5 percentage points, making the conversion fairer than a flat ÷ 10.
For CBSE Class 10 results, yes. For university degrees, check your university's own conversion rule — many publish a different formula on the marksheet or issue a separate conversion certificate.
In India, CGPA is usually on a 10-point scale (CBSE, most universities). US institutions use a 4.0 GPA scale — that is a different system and needs a different conversion. Use our GPA Calculator (4.0 scale) for that.
