SGPA to CGPA Calculator
What Is SGPA to CGPA Conversion?
The SGPA to CGPA calculator computes your Cumulative Grade Point Average from multiple semester SGPAs. CGPA represents your overall academic performance across all completed semesters, weighted by credit hours. This calculation is essential for final transcripts, graduation requirements, and applications requiring cumulative academic standing.
CGPA Calculation Formula
CGPA = Σ(SGPA × Semester Credits) ÷ Σ(Total Credits)
Each semester's contribution is proportional to its credit load. Semesters with more credits have greater impact on your cumulative average.
Example Calculation
Calculating CGPA from 4 Semesters
Sem 1: SGPA 7.5, Credits 22 → Points = 165
Sem 2: SGPA 8.0, Credits 24 → Points = 192
Sem 3: SGPA 8.2, Credits 23 → Points = 188.6
Sem 4: SGPA 8.5, Credits 25 → Points = 212.5
Total Points: 165 + 192 + 188.6 + 212.5 = 758.1
Total Credits: 22 + 24 + 23 + 25 = 94
CGPA = 758.1 ÷ 94 = 8.07

- Enter credits as shown on your marksheet (credit hours, not credit points).
- Some universities exclude certain courses from CGPA—verify with your registrar.
- If credits vary significantly between semesters, the weighting matters more.
Frequently Asked Questions
CGPA is calculated as the credit-weighted average of all semester SGPAs. Formula: CGPA = Σ(SGPA × Credits) ÷ Σ(Credits). Multiply each semester's SGPA by its credit hours, sum all products, then divide by total credits across all semesters. This ensures heavier course loads appropriately impact your cumulative average.
No, semesters are weighted by credit hours. A semester with 25 credits contributes more to your CGPA than one with 20 credits. This ensures that heavier course loads appropriately impact your cumulative average. If you take more courses or higher-credit courses in one semester, that semester matters more.
If all semesters have equal credits, you can simply average the SGPAs. However, most programs have varying credits per semester. For accurate CGPA, you need each semester's credit count, typically found on your marksheet or academic portal. Using incorrect credits will give an inaccurate result.
Differences can occur if: some courses are excluded (like remedial courses), your university uses credit points instead of credit hours, grace marks or rounding rules apply, or certain grades (I, W, P) are handled differently. Always cross-check with your official transcript for formal applications.
Most universities round CGPA to two decimal places. Some use one decimal or report to three places. Check your university's policy. This calculator shows two decimal places, which is the most common standard in Indian universities and aligns with UGC guidelines.
Yes, but it becomes harder as you accumulate more credits. The more credits you've completed, the less impact each new semester has. To significantly raise CGPA, you need consistently higher SGPAs over multiple semesters or retake courses for grade replacement if allowed. Plan early for maximum improvement potential.

Inputs Explained
- Semester Number: Identifies which semester's data you're entering (Semester 1, 2, 3, etc.).
- SGPA: Semester Grade Point Average for that term. Enter the value from your marksheet (typically 0-10).
- Credits: Total credit hours for that semester. This weights each semester's contribution to CGPA.

Limitations & Notes
- CGPA calculation assumes all semesters use the same grading scale (typically 10-point).
- Some universities exclude certain courses (remedial, audit) from CGPA; this calculator includes all entered data.
- Credit hours must be accurate; incorrect credits will produce wrong CGPA values.
- Universities may apply rounding rules (round up at 0.5) that differ from mathematical rounding.
- Backlog or failed subjects may be handled differently by your institution.
- For official CGPA, always refer to your university's student portal or registrar.
