How it's calculated
The UGC's guidelines on the Choice Based Credit System (CBCS) calculate CGPA "in the same manner" as SGPA: each semester's SGPA is weighted by the credits of that semester.
- For each semester, multiply the SGPA by the semester's total credits.
- Add these up across all semesters.
- Add up the credits of all semesters.
- Divide the first total by the second, and round to 2 decimal places.

Worked example (from the UGC guidelines)
| Semester | Credits | SGPA | Credits × SGPA |
|---|---|---|---|
| Semester 1 | 20 | 6.9 | 138 |
| Semester 2 | 22 | 7.8 | 171.6 |
| Semester 3 | 25 | 5.6 | 140 |
| Semester 4 | 26 | 6.0 | 156 |
| Semester 5 | 26 | 6.3 | 163.8 |
| Semester 6 | 25 | 8.0 | 200 |
| Total | 144 | 969.4 |
CGPA = 969.4 ÷ 144 = 6.73
Why credits matter
In the UGC example above, a simple average of the six SGPAs gives 6.77, but the correct credit-weighted CGPA is 6.73. The difference comes from semesters having different credit totals: semesters with more credits count for more.
If every semester in your programme has the same number of credits, both methods give the same answer. If you do not know your credits, choose "SGPA only" for a rough figure, then check it against your marksheet.
Tips
- Use the SGPA printed on each semester's grade card, not a figure you worked out yourself.
- Use the total credits registered for each semester, as shown on the grade card.
- If you repeated or improved a course, your university's regulations decide which grade counts. Use the SGPA your university shows after the change.
What to do with your CGPA
Most applications ask for CGPA, a percentage, or both. For a percentage, use the conversion formula set by your own university, and if an employer or college needs proof, ask your university for a conversion certificate.
Frequently asked questions
How do I convert SGPA to CGPA?
Multiply each semester’s SGPA by that semester’s total credits, add the results, and divide by the total credits of all semesters. This is the UGC formula: CGPA = Σ(Ci × Si) ÷ ΣCi.
Is CGPA just the average of my SGPAs?
Only if every semester has the same number of credits. Under the UGC method each semester is weighted by its credits, so a 26-credit semester counts more than a 20-credit one. If you do not know your credits, the simple average is a rough guide only.
Where do I find the credits for each semester?
The total credits for a semester are usually printed on your semester marksheet or grade card, next to the SGPA. You can also add up the credits of each course from your syllabus.
How many decimal places should CGPA have?
The UGC guidelines say SGPA and CGPA are rounded off to 2 decimal places. This calculator shows 2 decimal places.
Can I calculate CGPA before my final semester?
Yes. Enter the semesters you have completed. The result is your CGPA so far, which is also what most marksheets show at the end of each semester.
How do I convert my CGPA into a percentage?
There is no single national formula. Each university sets its own, often printed on the marksheet or in its regulations. Use your university’s formula, and ask the examination branch for a conversion certificate if an employer or college needs one.
