SGPA, CGPA, and the credit-weighted average
CGPA = Σ (SGPAᵢ × creditsᵢ) ÷ Σ (creditsᵢ). Each semester contributes proportionally to its credit hours. A heavy 25-credit semester moves the CGPA more than a light 18-credit semester with the same SGPA. The calculator at allgradecalculator.com applies this formula across an unlimited number of semesters.
Step-by-step
- Add a row for every completed semester.
- Enter the SGPA from the marks sheet and the credit hours for that semester.
- Add additional rows with + Add semester for each new term.
- Read the cumulative CGPA at the bottom.
Worked example
| Semester | SGPA | Credits |
|---|---|---|
| 1 | 8.4 | 24 |
| 2 | 8.7 | 22 |
| 3 | 9.1 | 26 |
| 4 | 8.9 | 24 |
CGPA = (8.4 × 24 + 8.7 × 22 + 9.1 × 26 + 8.9 × 24) ÷ (24 + 22 + 26 + 24) = (201.6 + 191.4 + 236.6 + 213.6) ÷ 96 = 843.2 ÷ 96 ≈ 8.78.
SGPA to CGPA in Indian universities
- VTU and Anna University use credit-weighted CGPA.
- JNTU Hyderabad uses a similar credit-weighted CGPA on a 10-point scale.
- Some autonomous engineering colleges use the simple average of all SGPAs — check your academic regulations before relying on a credit-weighted result.
- Mumbai University reports both SGPI (semester) and CGPI (cumulative) using the same logic.
