How to calculate your CGPA
CGPA is the average of your semester grade points, weighted by credits: multiply each semester's SGPA by its credits, add them up, and divide by the total credits. With equal credits every semester, it is simply the average of your SGPAs. CBSE's CGPA was the average of the grade points of your five main subjects.
Questions
How do I convert CGPA to percentage?
Use the formula your board or university publishes. For CBSE it is CGPA × 9.5, so 8.6 CGPA is 81.7%. Many Indian engineering universities use (CGPA − 0.75) × 10 or (CGPA − 0.5) × 10 instead. Pick yours in the calculator and it shows the percentage and the working.
Why does CBSE multiply by 9.5?
CBSE worked out 9.5 as the average ratio between marks and grade points over several years of results, so CGPA × 9.5 gives an indicative percentage. It is an estimate, not your exact marks.
Which formula does my university use?
Look at the back of your grade card or transcript, or your university's regulations: most state the conversion formula there. If yours is not in the list, choose Custom and enter its multiplier and the number it subtracts.
How do I convert percentage back to CGPA?
Reverse the formula: divide the percentage by the multiplier and add back what was subtracted. For CBSE, 76% ÷ 9.5 = 8.0 CGPA. The calculator does this in the second box.
What is the difference between SGPA and CGPA?
SGPA is your grade point average for one semester. CGPA is the cumulative average over all the semesters so far, weighted by the credits of each semester. You convert CGPA, not SGPA, for job and admission forms that ask for a percentage.
Is this the official percentage for my certificate?
No. It is the standard conversion, useful for forms that ask for a percentage. Where an official equivalent percentage is needed, your university can issue a certificate with it.
