How CGPA is calculated from SGPA
CGPA (Cumulative Grade Point Average) is the average of your semester grade point averages (SGPA) across a programme. When every semester carries the same credits, it is the plain average. When credits differ, each SGPA is weighted by its semester credits:
CGPA = Σ (SGPA × credits) ÷ Σ credits
The calculator above does exactly this. If you leave the credits boxes empty it treats every semester equally; if you fill them in, a semester with more credits counts for more. Some universities calculate CGPA from course-level grade points instead, so your official figure can differ slightly, and your university’s regulations always win.
Worked example
| Semester | SGPA | Credits | SGPA × credits |
|---|---|---|---|
| 1 | 8.2 | 24 | 196.8 |
| 2 | 7.8 | 26 | 202.8 |
| 3 | 8.6 | 24 | 206.4 |
| Total | 74 | 606.0 |
CGPA = 606.0 ÷ 74 = 8.19. The plain average of the three SGPAs is 8.20, so weighting by credits changes the answer slightly. At the CBSE multiplier, 8.19 × 9.5 is about 77.8%.
CGPA to percentage quick reference
| CGPA | Percentage |
|---|---|
| 6.0 | 57.0% |
| 7.0 | 66.5% |
| 8.0 | 76.0% |
| 9.0 | 85.5% |
| 10.0 | 95.0% |
The × 9.5 rule is the CBSE formula, and many institutions use it, but others publish their own multiplier or conversion table. For more scales, including a 4.0 GPA and the reverse conversion, use our CGPA to percentage calculator. For a 4.0 scale average, use the GPA calculator.
Frequently asked questions
How do I calculate CGPA from SGPA?
Multiply each semester’s SGPA by that semester’s credits, add the results, and divide by the total credits. If every semester has the same credits, CGPA is simply the average of your SGPAs.
What is the CGPA formula?
CGPA = (SGPA₁ × credits₁ + SGPA₂ × credits₂ + …) ÷ (credits₁ + credits₂ + …). Some universities calculate it over grade points per course instead, so check your university’s regulations.
Is CGPA the same as the average of my SGPAs?
Only when all semesters carry the same number of credits. When credits differ, the credit-weighted CGPA can be higher or lower than the plain average.
How do I convert CGPA to percentage?
CBSE uses percentage = CGPA × 9.5, and many institutions follow it, but several universities publish their own formula or conversion table. Use the multiplier your university specifies, or try our CGPA to percentage calculator.
Is the result from this CGPA calculator official?
No. It is an estimate based on the formula above. Your university’s published CGPA and conversion rules decide the figure that counts on your transcript and applications.
