To calculate CGPA (Cumulative Grade Point Average), add the total grade points earned in all semesters and divide by the total number of credits.
Formula:
CGPA = (Total Credit Points Earned) ÷ (Total Credits)
For example, if a student earns 180 total grade points over 45 credits, then CGPA = 180 ÷ 45 = 4.0.

What is CGPA?
CGPA stands for Cumulative Grade Point Average, which represents the overall academic performance of a student over multiple semesters. It is measured on a scale (usually 10-point or 4-point) depending on the country or institution.
-
10-Point Scale: Common in Indian universities such as VIT, DU, and CBSE schools.
-
4-Point Scale: Used in most US universities.
CGPA is more comprehensive than SGPA because it considers the cumulative performance across all semesters.

Example:
If a student’s semester results are:
| Semester | Grade Points | Credits | Grade Points × Credits |
|---|---|---|---|
| 1st | 8.0 | 20 | 160 |
| 2nd | 8.5 | 22 | 187 |
| 3rd | 9.0 | 25 | 225 |
| 4th | 8.2 | 20 | 164 |
| Total | – | 87 | 736 |
Then,

How to Calculate CGPA from SGPA
SGPA (Semester Grade Point Average) refers to your average grade for one semester. To find your CGPA from SGPA:
Formula:
Example:
If your SGPAs are: 8.2, 8.5, 9.0, 8.6
You can also use this SGPA to CGPA Calculator for automatic conversion.
How to Calculate Percentage from CGPA
Many students need to convert their CGPA into a percentage for applications or resume formats.
Formula (as per CBSE and UGC guidelines):
Example:
If your CGPA = 8.0,
then Percentage = 8.0 × 9.5 = 76%
To skip manual math, try the CGPA to Percentage Calculator.
How to Calculate CGPA from Marks
If your university provides marks instead of grades, you can convert them using the following formula:
Example:
If your overall percentage is 85%,
then CGPA = 85 ÷ 9.5 = 8.95
This method is widely accepted across Indian universities including CBSE and VIT.
How to Calculate Overall CGPA of All Semesters
To calculate your overall CGPA for multiple semesters:
-
Note down the SGPA for each semester.
-
Add them all together.
-
Divide by the number of semesters.
Example:
SGPA = 8.1, 8.4, 8.9, 9.0, 8.8
If you have credit-weighted semesters, use total grade points and credits instead for more accurate results.
You can also use the Grade Average Calculator for an easy method.
VIT CGPA Calculator and Formula
The Vellore Institute of Technology (VIT) uses a specific CGPA system based on credits.
Formula (as per VIT policy):
Grade Table (Official VIT):
| Grade | Points | Description |
|---|---|---|
| S | 10 | Excellent |
| A | 9 | Very Good |
| B | 8 | Good |
| C | 7 | Average |
| D | 6 | Satisfactory |
| E | 5 | Pass |
| F | 0 | Fail |
To simplify this, VIT students can use the VIT CGPA Calculator that follows the official formula.
Convert SGPA to CGPA Easily
If you want to convert multiple semester SGPAs to CGPA, the formula is simple:
Example:
SGPA for 4 semesters = 7.9, 8.3, 8.6, 8.2
Try the SGPA to CGPA Calculator for automatic results.
