How to use the Percentage to CGPA Calculator
- Enter your overall percentage, for example 79.8.
- Read the CGPA. It is shown to two decimal places.
- Use the check line to confirm that multiplying the CGPA by 9.5 returns your percentage.
- Confirm with the institution that asks for the CGPA that it accepts the CBSE method.
Formula used
CGPA = Percentage ÷ 9.5 (CBSE method for a 10-point scale).
Worked example
Here is the Percentage to CGPA Calculator worked through with the example values shown above, so you can check each step by hand.
| Inputs | |
|---|---|
| Percentage | 79.8 % |
| Result | |
| CGPA (out of 10) | 8.4 |
| Check | 8.4 × 9.5 = 79.8% |
Percentage to CGPA reference
Common percentages converted to CGPA using the CBSE method.
| Percentage | CGPA (out of 10) |
|---|---|
| 50 % | 5.26 |
| 60 % | 6.32 |
| 70 % | 7.37 |
| 75 % | 7.89 |
| 80 % | 8.42 |
| 85 % | 8.95 |
| 90 % | 9.47 |
| 95 % | 10 |
The conversion and an example
CGPA = percentage ÷ 9.5. For 79.8% the CGPA is 79.8 ÷ 9.5 = 8.4. The reverse conversion, CGPA × 9.5, takes you back to the percentage, which is why this calculator shows a check line.
Other common values: 60% is 6.32, 70% is 7.37, 75% is 7.89, 85% is 8.95 and 90% is 9.47. A perfect 100% would give 10.53, which is slightly above 10, so CBSE-style conversion is meant for normal ranges, and real CGPAs are capped at 10.
Why different institutions use different rules
CGPA is the average of grade points, and each board or university defines grade points differently. The factor 9.5 comes from CBSE’s analysis of how grade points relate to marks in its own system, and it is not a universal law. Some universities use 10, some use a table of ranges and some use their own formula printed on the transcript.
If you are applying abroad, many universities and evaluation services also have their own conversion methods, and some ask for a certified statement from your institution instead.
When to use this conversion
Use it when the form clearly accepts the CBSE method, or when you only need an approximate comparison. For official uses such as admissions, job applications and visas, ask your college for a certificate or use the conversion formula it prints on the marksheet.
Do not quote a converted CGPA as if it were an official one without saying how you converted it, because mismatches can cause trouble later in verification.
Converting the other way
To go from CGPA to percentage, use the CGPA to Percentage calculator on this site, which multiplies by 9.5. The two calculators are inverses, so a CGPA of 8.4 gives 79.8% and 79.8% gives 8.4.
Rounding can cause small differences. A CGPA of 8.4 and one of 8.41 differ by about 0.1 percentage points.
Check which scale and formula to use
Dividing by 9.5 is the CBSE method, so 79.8% becomes a CGPA of 8.4. Some institutions use other rules, such as dividing by 10 (79.8% would be 7.98) or using a table of ranges. Before you quote a CGPA, check the rule the receiving institution accepts, and make it clear which one you used.
The CGPA is capped at 10, so any percentage above 95% is shown as at most 10 on the official scale, and a CGPA on a 4-point scale cannot be obtained from this simple formula. Convert to the scale the form asks for, and keep your original marksheet at hand in case you are asked for proof.
Frequently asked questions
How do I convert percentage to CGPA?
Divide the percentage by 9.5 for the CBSE method. For 79.8%, the CGPA is 8.4.
Is 9.5 the same for every university?
No. Some universities use different formulas or tables. Use the one your institution or the receiving organisation accepts.
Can the result exceed 10?
For percentages above 95, the formula gives a value above 10. A real CGPA cannot exceed 10, so cap it at 10.
What is CGPA?
Cumulative grade point average, the average of grade points earned across subjects or semesters.
What is the difference between CGPA and SGPA?
SGPA is for one semester and CGPA is the cumulative average across semesters.
How do I convert CGPA back to percentage?
Multiply the CGPA by 9.5.
Can I divide by 10 instead of 9.5?
Only if the institution you are applying to accepts it. The CBSE method uses 9.5, but other institutions use their own rule.
