SGPA calculator
Calculate your semester grade point average (SGPA) on the 10-point scale.
SGPA (10-point)
What SGPA means
SGPA (Semester Grade Point Average) is your grade average for a single semester, on the 10-point scale. It's calculated exactly like CGPA — a credit-weighted average of your grade points — but only for the courses in that one term. Your CGPA is then built up from your SGPAs across all semesters.
How SGPA is calculated
Multiply each course's grade point by its credits, add them, and divide by the semester's total credits:
SGPA = Σ(grade point × credits) ÷ Σ(credits)
Grade points follow the standard scale: O = 10, A+ = 9, A = 8, B+ = 7, B = 6, C = 5, P = 4.
Worked example
One semester with four subjects:
- Data Structures — 4 credits, A+ (9)
- Digital Logic — 3 credits, A (8)
- Maths III — 4 credits, B+ (7)
- Lab — 1 credit, O (10)
Weighted points = (9×4) + (8×3) + (7×4) + (10×1) = 36 + 24 + 28 + 10 = 98. Total credits = 12. SGPA = 98 ÷ 12 = 8.17 for that semester.
Common mistakes to avoid
- Forgetting lab/practical credits. Labs usually carry 1–2 credits and still count — leaving them out changes your SGPA.
- Treating SGPA as CGPA. One good semester isn't your CGPA. Combine all semesters with the SGPA to CGPA tool.
- Plain-averaging grades. A heavier course should count more — always weight by credits.
