What Is CGPA?
CGPA stands for Cumulative Grade Point Average. It represents a student’s overall academic performance across multiple subjects or semesters.
Unlike percentage, which expresses marks out of 100, CGPA represents academic performance using grade points. Depending on the institution, these points are measured on a 4-point, 5-point or 10-point scale.
How to Convert CGPA to Percentage
Converting CGPA to percentage expresses your overall grade point average as a percentage. The calculation depends on the conversion method being used.
CGPA to Percentage Formula for a 10-Point Scale
One formula used by some institutions is:
Multiply your CGPA by 10, then subtract 7.5 from the result.
Example: Convert 8.5 CGPA to Percentage
Suppose your CGPA is 8.5 on a 10-point scale. Using the formula above:
-
Step 1: Multiply your CGPA by 10.8.5 × 10 = 85
-
Step 2: Subtract 7.5.85 − 7.5 = 77.5%
Therefore, 8.5 CGPA equals 77.5% using this formula.
CGPA to Percentage Formula for a 5-Point Scale
The calculator uses proportional conversion for a 5-point scale. Divide your CGPA by 5 and multiply by 100.
Example: Convert 4 CGPA to Percentage
If your CGPA is 4.0 out of 5, the calculation is:
-
Step 1: Divide your CGPA by 5.4 ÷ 5 = 0.8
-
Step 2: Multiply by 100.0.8 × 100 = 80%
Therefore, 4.0 CGPA equals 80% using the proportional method.

CGPA vs Percentage: What Is the Difference?
CGPA represents academic performance as grade points accumulated across subjects or semesters, while percentage expresses marks as a value out of 100. The key difference is how academic results are calculated and presented.
| Feature | CGPA | Percentage |
|---|---|---|
| Full Form | Cumulative Grade Point Average | Marks expressed out of 100 |
| Representation | Grade points, such as 8.2 or 9.0 | Percentage values, such as 82% or 90% |
| Grading Scale | Commonly a 10-point scale in India; other scales are also used | A scale from 0% to 100% |
| Calculation | Based on the institution’s grading system and applicable subject credits | Marks obtained divided by total possible marks, multiplied by 100 |
| Conversion | Requires the applicable percentage conversion formula | Requires the applicable CGPA conversion formula |
FAQS
1. How do I convert CGPA to percentage?
Select your grading scale, enter your CGPA, and click Convert. For the 10-point formula (CGPA × 10) − 7.5, a CGPA of 8.5 equals 77.5%. Your university's prescribed conversion formula takes precedence.
2. What is 8 CGPA in percentage?
On a 10-point scale, 8 CGPA equals 72.5% using the formula (CGPA × 10) − 7.5. The equivalent percentage may differ if your university uses another conversion method.
3. How do I convert percentage to CGPA?
For the 10-point formula (CGPA × 10) − 7.5, use CGPA = (Percentage + 7.5) ÷ 10. For example, 80% converts to 8.75 CGPA. Use the reverse of your university's prescribed formula for an official result.
4. Is the CGPA-to-percentage formula the same for every university?
No. Universities may use different conversion formulas or official conversion tables. Check your institution's grading regulations to find the method applicable to your course.
5. How do I convert CGPA from a 5-point scale to percentage?
Using the proportional formula, divide your CGPA by 5 and multiply by 100. For example, 4.0 CGPA equals 80%. If your university provides a specific conversion formula, use that instead.
6. Is CGPA the same as percentage?
No. CGPA represents academic performance in grade points across subjects or semesters, while percentage expresses marks out of 100. Converting between them requires the applicable conversion formula.
