Formula

SGPA Calculator Formula — Explained Simply

The SGPA calculator formula follows the standard weighted average method used across all UGC-approved universities in India:

SGPA = Σ(Credit × Grade Points) ÷ Σ(Credits)

Example: 3 subjects: Subject A (4cr × 9pts) + Subject B (3cr × 8pts) + Subject C (2cr × 7pts)
SGPA = (36 + 24 + 14) ÷ (4+3+2) = 74 ÷ 9 = 8.22

SGPA to Percentage (Standard): Percentage = (SGPA − 0.75) × 10
KTU Formula: Percentage = (SGPA × 10) − 7.5
VTU Formula: Percentage = (SGPA − 0.5) × 10
SGPA to CGPA: CGPA = Average of all semester SGPAs

FAQ

SGPA Calculator — Frequently Asked Questions

How to convert SGPA to percentage?
The standard formula is: Percentage = (SGPA – 0.75) × 10. So an SGPA of 8.5 gives (8.5 – 0.75) × 10 = 77.5%. However, different universities use slightly different formulas. KTU uses (SGPA × 10) – 7.5, and VTU uses (SGPA – 0.5) × 10. Always confirm which formula your university follows. Our SGPA calculator to percentage tool handles all of these with a university dropdown selector.
How to convert SGPA to CGPA?
CGPA is the average of all your semester SGPAs. For example, if you have 6 semesters with SGPAs of 8.0, 8.2, 7.9, 8.5, 8.3, 8.1 — your CGPA = (8.0+8.2+7.9+8.5+8.3+8.1) ÷ 6 = 8.17. Use our SGPA calculator to CGPA feature and enter multiple semester SGPAs to compute your CGPA automatically.
What is the SGPA calculator formula for KTU?
For Kerala Technological University (KTU), the official SGPA calculator KTU formula is: Percentage = (SGPA × 10) – 7.5. So an SGPA of 9.0 would be (9.0 × 10) – 7.5 = 82.5%. This slightly differs from the national standard and applies specifically to B.Tech students under KTU’s grading system.
How to use SGPA calculator VTU (Visvesvaraya Tech University)?
For VTU students, the SGPA calculator VTU conversion formula is: Percentage = (SGPA – 0.5) × 10. So an SGPA of 8.0 gives (8.0 – 0.5) × 10 = 75%. VTU uses a 10-point grading scale where O grade = 10 points and P (Pass) = 5 points. Select “VTU” in our university dropdown to automatically apply this formula.
How to use this as a marks to SGPA calculator?
Click the “Marks to SGPA” tab, enter your total marks obtained and maximum marks possible. The calculator will first compute your percentage, then convert it to SGPA using the standard formula: SGPA = (Percentage ÷ 10) + 0.75. This is perfect as a number to SGPA calculator when you only have raw marks from your result sheet.
What is the SGPA calculator for CU (Calcutta University)?
Calcutta University (CU) follows the UGC-recommended 10-point grading scale. The SGPA calculator CU conversion is: Percentage = SGPA × 9.5. So an SGPA of 8.0 gives 8.0 × 9.5 = 76%. Select “CU / Calcutta University” in the dropdown to use this specific conversion automatically.
