What is CGPA?
CGPA (Cumulative Grade Point Average) is the average of grade points earned in all subjects across semesters. Instead of calculating marks individually, universities convert marks into grade points and then calculate the average.
CGPA helps universities measure student performance in a consistent way across multiple courses and semesters.
For example:
Universities in India and Bangladesh often use a 10.0 scale
Many Pakistani universities use a 4.0 scale
Some international institutions use 5.0, 7.0, or 12.0 grading systems
Even though grading scales differ, the calculation method remains the same.
Standard CGPA Formula
The CGPA calculation method is simple and used worldwide.
CGPA Formula
CGPA = Total Quality Points ÷ Total Credit Hours
Understanding the Formula
Credit Hours
Each subject has assigned credit hours based on its importance or workload.
Grade Points
Every grade corresponds to a numerical value depending on the grading scale.
Quality Points
Quality Points are calculated using the formula:
Quality Points = Credit Hours × Grade Point
After calculating quality points for each subject, the final CGPA is calculated by dividing total quality points by total credit hours.
Example of CGPA Calculation
Suppose a student has the following grades:
| Subject | Credit Hours | Grade Point |
|---|---|---|
| Mathematics | 3 | 3.7 |
| Physics | 4 | 3.5 |
| English | 2 | 3.8 |
| Computer Science | 3 | 3.9 |
Step 1: Calculate Quality Points
Mathematics → 3 × 3.7 = 11.1
Physics → 4 × 3.5 = 14.0
English → 2 × 3.8 = 7.6
Computer Science → 3 × 3.9 = 11.7
Step 2: Total Values
Total Quality Points = 44.4
Total Credit Hours = 12
Step 3: CGPA
CGPA = 44.4 ÷ 12 = 3.70
Instead of doing these steps manually, students can calculate results instantly using the online CGPA calculator.
CGPA Grading Scales Used Worldwide
Different countries use different grading scales, but the calculation method remains identical.
4.0 Scale
This is widely used in:
Pakistan
United States
Canada
Some Nigerian universities
Example grading structure:
| Grade | Grade Point |
|---|---|
| A | 4.0 |
| B | 3.0 |
| C | 2.0 |
| D | 1.0 |
5.0 Scale
Some universities use a 5-point grading system, especially in specialized institutions.
Example:
| Grade | Grade Point |
|---|---|
| A | 5.0 |
| B | 4.0 |
| C | 3.0 |
| D | 2.0 |
7.0 Scale
The 7-point grading scale is commonly used in Australia.
Example:
| Grade | Grade Point |
|---|---|
| HD | 7 |
| D | 6 |
| C | 5 |
| P | 4 |
10.0 Scale
The 10-point system is widely used in:
India
Bangladesh
engineering universities in South Asia
Example:
| Grade | Grade Point |
|---|---|
| O | 10 |
| A+ | 9 |
| A | 8 |
| B | 7 |
| C | 6 |
12.0 Scale
Some international education systems and certain universities use a 12-point grading system, which works the same way but with a higher maximum grade value.
How to Convert Percentage to CGPA
Many students receive marks in percentage but need to convert them into CGPA for university applications.
You can quickly convert percentage to grade points using this tool:

Different universities use different formulas for conversion.
Example formula used by many Indian institutions:
CGPA = Percentage ÷ 9.5
Example:
76% ÷ 9.5 = 8.0 CGPA
However, always check your university rules because the conversion formula may vary.
How to Convert CGPA to Percentage
Students often need to convert CGPA back into percentage for job applications or scholarships.
You can calculate it instantly here:
https://cgpacalculatoronline.net/cgpa-to-percentage-calculator/
Example conversion formula:
Percentage = CGPA × 9.5
Example:
8.2 CGPA × 9.5 = 77.9%
Again, universities may use slightly different conversion formulas.
