CGPA to Percentage Conversion Formulas
Converting CGPA to percentage depends on the grading scale used by your institution. Different countries and universities use different formulas. Here are the most commonly used conversion formulas:
1. Indian Universities (10-Point Scale)
Standard CBSE Formula:
Percentage = CGPA × 9.5
This is the official formula prescribed by CBSE (Central Board of Secondary Education) and is widely used across Indian schools and universities.
Example 1:
CGPA = 8.5
Percentage = 8.5 × 9.5
Percentage = 80.75%
Example 2:
CGPA = 9.2
Percentage = 9.2 × 9.5
Percentage = 87.40%
Example 3:
CGPA = 7.8
Percentage = 7.8 × 9.5
Percentage = 74.10%
Why 9.5 and not 10?
The multiplier 9.5 is used instead of 10 because in the CBSE grading system, a CGPA of 10 indicates marks between 91-100%, not exactly 100%. This conversion accounts for the grade range and provides a more accurate percentage representation.
2. International Universities (4-Point GPA Scale)
Standard GPA Formula:
Percentage = (GPA / 4.0) × 100
This formula is used in the USA, Canada, and many international universities that follow the 4.0 GPA scale.
Example 1:
GPA = 3.5
Percentage = (3.5 / 4.0) × 100
Percentage = 0.875 × 100
Percentage = 87.50%
Example 2:
GPA = 3.8
Percentage = (3.8 / 4.0) × 100
Percentage = 0.95 × 100
Percentage = 95.00%
Example 3:
GPA = 2.7
Percentage = (2.7 / 4.0) × 100
Percentage = 0.675 × 100
Percentage = 67.50%
3. Generic Formula (Any Scale)
Universal Conversion Formula:
Percentage = (CGPA / Maximum Scale) × 100
This formula works for any grading scale (5-point, 7-point, etc.) and provides a direct proportional conversion.
Example (5-Point Scale):
CGPA = 4.2 (out of 5)
Percentage = (4.2 / 5.0) × 100
Percentage = 0.84 × 100
Percentage = 84.00%
Example (7-Point Scale):
CGPA = 5.8 (out of 7)
Percentage = (5.8 / 7.0) × 100
Percentage = 0.8286 × 100
Percentage = 82.86%

What is CGPA?
CGPA (Cumulative Grade Point Average) is a grading system used to evaluate a student's overall academic performance across all subjects and semesters. It represents the average of grade points obtained in all subjects, excluding additional subjects as per the scheme of studies.
How CGPA is Calculated:
Step 1: Calculate Grade Points for each subject based on marks obtained
Step 2: Find the average of all Grade Points
Step 3: The result is your CGPA
CGPA = Sum of Grade Points / Number of Subjects
CGPA Calculation Example:
Let's say a student has the following grade points in 5 subjects:
- Subject 1: 9 GP
- Subject 2: 8 GP
- Subject 3: 9 GP
- Subject 4: 8 GP
- Subject 5: 9 GP
CGPA = (9 + 8 + 9 + 8 + 9) / 5
CGPA = 43 / 5
CGPA = 8.6
Grade Points to Percentage Mapping (CBSE)
| Marks Range | Grade Point | Grade | Performance |
|---|---|---|---|
| 91 - 100 | 10 | O | Outstanding |
| 81 - 90 | 9 | A+ | Excellent |
| 71 - 80 | 8 | A | Very Good |
| 61 - 70 | 7 | B+ | Good |
| 51 - 60 | 6 | B | Above Average |
| 41 - 50 | 5 | C | Average |
| 33 - 40 | 4 | D | Pass |
| Below 33 | - | F | Fail |

Frequently Asked Questions
How do I convert my CGPA to percentage?
The most common method in India is to multiply your CGPA by 9.5. For example, if your CGPA is 8.5, your percentage would be 8.5 × 9.5 = 80.75%. However, different universities may use different formulas, so always check with your institution for the exact conversion method they use.
Is CGPA better than percentage?
CGPA and percentage are two different ways to represent academic performance. CGPA reduces competition and stress among students by using a grading scale instead of exact marks. It also accounts for overall performance across subjects. However, percentage gives a more precise representation of marks obtained. Neither is inherently better; they serve different purposes in the education system.
What is a good CGPA on a 10-point scale?
On a 10-point scale, a CGPA of 8.0 or above is considered excellent and equivalent to 75%+ percentage. A CGPA of 9.0+ is outstanding (85%+), 7.0-7.9 is very good (66-74%), 6.0-6.9 is good (57-65%), and 5.0-5.9 is above average (47-56%). Anything below 5.0 indicates room for improvement.
Can I get 100% from a CGPA of 10?
When using the standard CBSE formula (CGPA × 9.5), a CGPA of 10 converts to 95%, not 100%. This is because a CGPA of 10 represents the grade band of 91-100%, so the conversion uses 9.5 as the multiplier to represent the average of this range. Different universities may have different conversion methods.
How do I calculate CGPA from individual subject marks?
First, convert each subject's marks to grade points using your institution's grading scale (e.g., 91-100 = 10 GP, 81-90 = 9 GP). Then, add up all the grade points and divide by the number of subjects. For example: If you have 5 subjects with grade points 9, 8, 9, 8, 9, your CGPA = (9+8+9+8+9)/5 = 43/5 = 8.6.
Why do different universities use different conversion formulas?
Universities adopt different conversion formulas based on their grading philosophies and the range their grade points represent. For instance, some universities believe their top grade represents a higher percentage range, leading to different multipliers. Anna University and VTU use (CGPA - 0.75) × 10, while Mumbai University uses CGPA × 7.25 + 11. Always use your institution's official formula for accurate conversion.
Does CGPA conversion affect college admissions?
Yes, CGPA conversion is crucial for college admissions, especially when applying to institutions that require percentage-based eligibility. Most colleges accept both CGPA and percentage, but they may convert your CGPA using their own formula. It's important to know your institution's official conversion method and carry proper documentation showing how your percentage was calculated from CGPA.
