How to Calculate CBSE Percentage from Marks?
CBSE Class 10 and Class 12 percentage is calculated by adding the marks obtained in all subjects (usually best 5, including one language) and dividing by the total maximum marks, then multiplying by 100.
Percentage = (Total Marks Obtained ÷ Total Maximum Marks) × 100
Example: If you scored 470 out of 500 across 5 subjects, your percentage = (470 ÷ 500) × 100 = 94%.
How to Convert CBSE CGPA to Percentage?
CBSE officially recommends the same UGC formula used for higher education:
Percentage = CGPA × 9.5
For example, a CBSE CGPA of 9.4 converts to 9.4 × 9.5 = 89.3%. This is the formula accepted by CBSE, most colleges, and government job applications.
