Your CGPA combines every semester you have completed, weighted by the credits in each. Enter the SGPA and total credits for each semester to see your cumulative grade point average and the full working.
Enter each semester's SGPA, separated by commas.
Enter each semester's total credits in the same order.
Read the cumulative CGPA.
CGPA: CGPA = Σ(SGPA × semester credits) ÷ Σ semester credits
CGPA, the Cumulative Grade Point Average, sums up your whole programme so far in one number. This calculator combines the SGPA of each completed semester, weighted by that semester's credits, which is how Indian universities compute the CGPA printed on a transcript.
It answers questions such as 'What is my CGPA after five semesters?' and 'If I get 9 this semester, where will my CGPA land?' Placement cells often set CGPA cut-offs, such as 7.0 or 7.5 with no active backlogs, so knowing your running figure matters well before the final year.
Enter each semester's SGPA and total credits in the same order. If every semester had equal credits, the answer equals the plain average; otherwise the weights make a difference.
1. Collect the SGPA of every completed semester from your grade cards.
2. Note the total credits registered or earned in each semester, as your university counts them.
3. Multiply SGPA × credits for each semester.
4. Add these products to get total credit points.
5. Add the credits of all semesters.
6. Compute CGPA = Σ(SGPA × semester credits) ÷ Σ credits.
7. To plan ahead, add the expected next SGPA and its credits and recompute.
Each SGPA is already a credit-weighted mean of subject grade points. Multiplying it by the semester's credits recovers that semester's total credit points. Adding across semesters and dividing by all credits gives exactly the credit-weighted average of every subject taken, as if all subjects were in one list. That is why the method is consistent: the CGPA does not depend on how subjects were grouped into semesters. A plain average of SGPAs would over-weight light semesters.
Each new semester adds its credits to a growing total. After six semesters of about 22 credits each, the next semester is only one-seventh of the weight. Raising a CGPA from 7.2 to 7.5 then requires the new SGPA to be well above 7.5. You can solve for the needed SGPA: needed = (target × total credits after − current CGPA × credits so far) ÷ new credits. Early semesters shape the CGPA most, so a weak first year is hard to undo.
When a failed or improvement subject is cleared later, most universities replace the earlier grade with the new one and recompute the SGPA of the original semester, or record the change in the later semester. Either way the credits for that subject count once. If you are tracking your own CGPA, update the semester the university assigns the new grade to, and do not add the credits twice. Rules on grade caps for supplementary attempts differ, so check your regulations.
Rahul has completed six semesters of his B.E. with SGPAs of 7.6, 8.1, 8.4, 8.9, 8.2 and 8.7, and the semesters carried 20, 22, 24, 24, 22 and 20 credits. He needs his CGPA for a campus placement form.
Multiply each grade point by its credits: 7.6 × 20 = 152 8.1 × 22 = 178.2 8.4 × 24 = 201.6 8.9 × 24 = 213.6 8.2 × 22 = 180.4 8.7 × 20 = 174
Add the products (credit points): 152 + 178.2 + 201.6 + 213.6 + 180.4 + 174 = 1,099.8
Add the credits: 20 + 22 + 24 + 24 + 22 + 20 = 132
CGPA = total credit points ÷ total credits: 1,099.8 ÷ 132 = 8.33
Answer: CGPA 8.33; Total credits 132; Semesters counted 6
Averaging SGPAs directly when semesters have different credits.
Counting a re-attempted subject's credits twice.
Using credits registered when the university uses credits earned, or the other way round.
Rounding each SGPA before combining instead of using the printed two-decimal values.
Checking eligibility for campus placements with CGPA cut-offs.
Working out the SGPA needed next semester to reach a target CGPA.
Verifying the CGPA on a provisional or final transcript.
Preparing applications for higher studies that ask for cumulative performance.
Can I just average my SGPAs?
Only if every semester has exactly the same credits. Otherwise use credits as weights, as this calculator does.
How do I convert my CGPA to percentage?
Use the CGPA to Percentage Calculator with the rule your university publishes.
