Marks to CGPA

Convert your raw exam marks directly into Percentage and a 10-point CGPA.

CBSE Class 10: Grade points are assigned per subject using official mark slabs. CGPA = average of best subjects grade points. Percentage estimate = CGPA × 9.5. Minimum pass: 33 marks per subject.

Understanding Marks to CGPA Conversion

For students who've just received a mark sheet listing subject-wise scores rather than a final CGPA, this calculator bridges that gap. Marks-to-CGPA conversion follows the CBSE nine-point grading scale, where each subject's marks are first converted into a grade point, and these grade points are then averaged across all subjects to arrive at your overall CGPA.

The grading table typically looks like this:

Marks RangeGradeGrade Point
91–100A110
81–90A29
71–80B18
61–70B27
51–60C16
41–50C25
33–40D4
21–32E1 (Fail)0
0–20E2 (Fail)0

Once each subject's marks are converted to a grade point using this table, the CGPA is calculated by taking a simple average: add up all the grade points and divide by the number of subjects.

A Worked Example

Suppose you scored the following in five subjects:

English:88 marks → Grade Point 9
Mathematics:95 marks → Grade Point 10
Science:76 marks → Grade Point 8
Social Science:82 marks → Grade Point 9
Second Language:91 marks → Grade Point 10

Sum of grade points: 9 + 10 + 8 + 9 + 10 = 46

Average Grade Point CalculationCGPA = 46 ÷ 5 = 9.2
CBSE CGPA = 9.20

This is your overall CGPA, which you can then further convert to a percentage using the standard 9.5 multiplier if needed (9.2 × 9.5 = 87.4%).

Where This Applies

This method is most commonly used for CBSE Class 10 results, where mark sheets list subject-wise scores and students (or their schools) need to calculate the overall CGPA. It's also useful for students at universities that publish subject-wise marks each semester but expect students to track their own running CGPA before the official calculation is released.

A Note on Additional Subjects

If you've taken an additional subject beyond the required five, CBSE rules state that the best five grade points are considered for CGPA calculation, and the additional subject's grade is mentioned separately on the mark sheet but doesn't factor into your main CGPA unless it replaces a lower-scoring compulsory subject.
