What is SGPA?

SGPA (Semester Grade Point Average) represents your academic performance in a single semester.

It is calculated based on the credit points of each subject and the grade points obtained.

Most universities in India and abroad follow a 10-point grading system, where SGPA ranges between 0 and 10.

What is CGPA?

CGPA (Cumulative Grade Point Average) is the overall average of all SGPAs across multiple semesters.

While SGPA reflects semester performance, CGPA shows your overall academic consistency.

Difference Between SGPA and CGPA

👉 In simple terms:
SGPA = Semester Score
CGPA = Overall Course Score

SGPA to Percentage Conversion

Many universities require percentage instead of SGPA. Our calculator instantly converts SGPA to percentage using the standard formula.

✅ SGPA to Percentage Formula

Percentage = (SGPA × 10) – 7.5

⚠️ Note: The formula may slightly vary depending on your university guidelines.

Example:

If SGPA = 8.2

Percentage = (8.2 × 10) – 7.5
Percentage = 82 – 7.5
Percentage = 74.5%

Percentage to SGPA Conversion

If you have your percentage and want to know your SGPA, use this reverse formula.

✅ Percentage to SGPA Formula

SGPA = (Percentage + 7.5) ÷ 10

Example:

If Percentage = 75%

SGPA = (75 + 7.5) ÷ 10
SGPA = 82.5 ÷ 10
SGPA = 8.25

SGPA to CGPA Conversion

CGPA is usually calculated as the average of all semester SGPAs.

Method 1: Simple Average Method

CGPA = (Sum of all SGPAs) ÷ (Number of Semesters)

Method 2: Credit-Based Weighted Method

If your university uses credit weightage:

CGPA = (Total Credit Points of All Semesters) ÷ (Total Credits)

Always verify your university’s grading policy before final calculation.

How to Calculate SGPA Manually?

Follow these steps:

Step 1:

Multiply the grade points of each subject by its credit value.

Step 2:

Add all the calculated grade points.

Step 3:

Add the total credits of all subjects.

Step 4:

Divide total grade points by total credits.

SGPA = Total Grade Points ÷ Total Credits
