The CBSE CGPA to percentage formula

Under the CBSE grading system for Class 10, overall percentage was indicated by multiplying CGPA by 9.5:

Percentage = CGPA × 9.5  ·  CGPA = Percentage ÷ 9.5

So a CGPA of 8.6 is about 81.7%, and a 10 CGPA is 95%. The same multiplier gives an indicative percentage for a single subject: a grade point of 9 (A2) is about 85.5%.

CBSE arrived at 9.5 by looking at how students with an A1 grade had actually scored: their marks averaged about 95, against a grade point of 10. The result is an indicative conversion, not a recalculation of your real marks. If an admission form asks for actual marks and your marksheet has them, use those.

How CBSE CGPA is calculated

CGPA is the average of the grade points in the five main subjects. The additional (sixth) subject is left out. With grades A1, A2, A1, B1 and A2, the grade points are 10, 9, 10, 8 and 9. They add up to 46, and 46 ÷ 5 gives a CGPA of 9.2, about 87.4%.

University CGPA to percentage formulas

Universities don't share one formula. Some use CGPA × 10, some use CGPA × 9.5, and others subtract a constant first, for example (CGPA − 0.75) × 10. Your university's formula is normally printed on the back of the transcript or published in its academic regulations. Choose Custom in the calculator above and enter its values for a and b.

If a form asks for a percentage and your university says nothing, attach the formula you used. Recruiters and admission offices handle that far better than an unexplained number.

For schools: grades and report cards without the arithmetic

Converting between marks, grade points and percentages by hand for a whole class is slow and easy to get wrong. In Premeena's report card module you define your own grading scale once: grade bands, grade points and how exam types are weighted. Teachers enter marks, and grades, term results and printable report cards are worked out for you. The same marks feed exam management, so nobody re-types anything.

Frequently asked questions

How do I convert CGPA to percentage for CBSE?

Multiply your CGPA by 9.5. For example, a CGPA of 9.2 × 9.5 = 87.4%. To go back from a percentage to CGPA, divide by 9.5.

Why does CBSE multiply CGPA by 9.5?

CBSE found that students with an A1 grade averaged about 95 marks, against a grade point of 10, so it uses 9.5 as the multiplier. The result is an indicative percentage, not your exact marks.

What percentage is 8.5 CGPA?

Under the CBSE ×9.5 formula, 8.5 CGPA is 80.75%. Under a simple ×10 formula it would be 85%, so check which formula your institution uses.

Is the additional subject included in CBSE CGPA?

No. CBSE CGPA is the average of the grade points of the five main subjects. The additional sixth subject is not included.

Which formula should I use for my university?

Use the one your university publishes, usually on the back of the transcript or in its academic regulations. Common forms are CGPA × 10, CGPA × 9.5 and (CGPA − a) × 10. Pick Custom in the calculator to enter your university's values.
