The official formula
- Subject-wise indicative percentage = 9.5 × grade point of the subject.
- Overall indicative percentage = 9.5 × CGPA.
- CGPA is the average of the grade points of all subjects, excluding the additional subject.
Example: grade points 10, 9, 9, 8 and 7 → CGPA 8.6 → 8.6 × 9.5 = 81.7%.
FAQ
Why does CBSE multiply by 9.5 and not 10?
That is the factor CBSE fixed in Circular No. 24 of 28 May 2010 for converting grade points into an indicative percentage. It is a conversion rule, not your actual marks.
What percentage is a 10 CGPA?
9.5 × 10 = 95% as an indicative percentage, although individual marks for A1 can be anywhere from 91 to 100.
Is the additional (sixth) subject included?
No. CGPA is the average of grade points excluding the additional subject.
Sources (checked 10 November 2026): CBSE Circular No. 24 dated 28 May 2010 (9.5 × GP / CGPA); CBSE circular on modified performance profile (nine-point grading scale, CGPA excluding the additional subject). Estimate, not an official result.
