CGPA to Percentage Calculator
Under CBSE's rule, percentage = CGPA × 9.5, so a CGPA of 8.5 equals 80.75%; universities that use a plain × 10 rule would show 85%. Pick your board or university to apply its published formula, or convert a percentage back to CGPA.

- 95%at a CGPA of 10
Step-by-step working
- Multiply the CGPA by 9.5: 8.5 × 9.5 = 80.75%
CGPA 8.5 under other formulas
| Formula | Percentage |
|---|---|
| CBSE Class 10 (CGPA × 9.5) | 80.75% |
| CGPA × 10 (Anna Univ., AKTU, VTU 2022, DU) | 85% |
| VTU 2015/2017/2018 schemes ((CGPA − 0.75) × 10) | 77.5% |
| SPPU 2022 notice (CGPA × 8.9) | 75.65% |
These are official rules for the boards and universities named, but an employer's, university's or exam body's own conversion rule always takes precedence. CBSE itself no longer calculates percentages; its 2023 notice leaves that to the admitting institution or employer.
How to use the CGPA to percentage calculator
- Choose CGPA → Percentage or Percentage → CGPA.
- Enter your CGPA on a 10-point scale, or your percentage.
- Pick the formula for your board or university. If yours isn’t listed, choose Custom and type the multiplier, and the amount to subtract first if your rule has one.
The result shows the converted value, the formula used, the highest percentage that formula can give, and the same number under each of the other formulas so you can compare.
CGPA to percentage formulas by board and university
There is no single national formula. Each board or university sets its own, and some have changed theirs. These are the rules published in each body’s own documents:
| Board or university | Formula | Applies to | CGPA 8.2 becomes |
|---|---|---|---|
| CBSE (Class 10) | CGPA × 9.5 | Grade sheets under the CGPA grading scheme | 77.9% |
| Anna University | CGPA × 10 | R2021 and 2023 regulations | 82% |
| AKTU | CGPA × 10 | Revised B.Tech ordinance 2018-19 | 82% |
| VTU | (CGPA − 0.75) × 10 | 2015, 2017 and 2018 schemes | 74.5% |
| VTU | CGPA × 10 | 2022 scheme | 82% |
| Delhi University | CGPA × 10 | Students graduating from 2022-23 | 82% |
| Delhi University | CGPA × 9.5 | Earlier CBCS rule | 77.9% |
| SPPU | CGPA × 8.9 | 2022 conversion notice | 72.98% |
Sources for the university rules: AKTU revised ordinance, VTU 2022 scheme regulations, Delhi University notification of February 2023 and SPPU conversion notice. The SPPU notice does not say which programmes it covers, so confirm with your college.
Worked examples
CBSE Class 10. A CGPA of 8.6 × 9.5 = 81.7%. A CGPA of 9.2 × 9.5 = 87.4%, and a perfect 10 × 9.5 = 95%.
VTU 2018 scheme. (8.20 − 0.75) × 10 = 7.45 × 10 = 74.5%. This is the illustration VTU gives in its own regulations.
Anna University. A CGPA of 7.8 × 10 = 78%.
Percentage back to CGPA. On the CBSE rule, 76% ÷ 9.5 = 8.0. A score above 95% has no CBSE CGPA equivalent, because 10 × 9.5 = 95.
CBSE CGPA and the 9.5 rule
Under CBSE’s grading scheme, each subject got a grade and a grade point. CGPA was the average of the grade points of the main subjects, leaving out a 6th additional subject. CBSE Circular No. 40 of 2009 set these bands:
| Marks | Grade | Grade point |
|---|---|---|
| 91–100 | A1 | 10 |
| 81–90 | A2 | 9 |
| 71–80 | B1 | 8 |
| 61–70 | B2 | 7 |
| 51–60 | C1 | 6 |
| 41–50 | C2 | 5 |
| 33–40 | D | 4 |
Circular No. 24 of 2010 then said the overall indicative percentage is 9.5 × CGPA, and each subject’s is 9.5 × its grade point. CBSE’s current mark sheets show marks, and in a November 2023 notice it said it does not calculate or declare percentages; if one is needed, the admitting institution or employer may work it out. For those mark sheets, use the marks percentage calculator.
When there is no formula
Some universities don’t use a fixed multiplier at all:
- University of Mumbai. A circular dated January 1, 2026 says the actual percentage based on the student’s marks from all semesters should be calculated, and it repealed the 2018 and 2019 conversion circulars.
- MAKAUT publishes a table instead of a formula: a DGPA of 6.25 equals 55%, 6.75 equals 60%, 7.25 equals 65%, 7.75 equals 70% and 8.25 equals 75%.
If your university gives a table or computes from marks, use that. A multiplier from another university will give a wrong answer.
Which conversion should you use?
Use the rule printed on your grade card, transcript or university regulations for your admission year. If an employer, exam body or foreign university states its own conversion, that rule wins, even if it differs from your university’s. When an application asks for a percentage and gives no rule, write the CGPA, the percentage and the formula you used, for example “8.2 CGPA (74.5% as per VTU formula)”.
For a 4-point GPA from a US-style system, the GPA calculator is the right tool rather than a CGPA multiplier.
CGPA to Percentage Calculator: frequently asked questions
How do I convert CGPA to percentage?
Multiply your CGPA by the factor your board or university publishes. For a CBSE Class 10 CGPA the rule is CGPA × 9.5, so 8.6 becomes 81.7%. Anna University and AKTU use CGPA × 10, so 7.8 becomes 78%.
Why does CBSE multiply CGPA by 9.5?
CBSE's Circular No. 24 of 2010 states that the overall indicative percentage of marks is 9.5 × CGPA, and the same rule appears in its 2013 examination bye-laws. The circular gives the rule without a derivation. The result is that a perfect 10 CGPA equals 95%.
What is 10 CGPA in percentage?
Under CBSE's rule it is 95%. Under a CGPA × 10 rule it is 100%, under VTU's (CGPA − 0.75) × 10 rule for its 2015 to 2018 schemes it is 92.5%, and under SPPU's × 8.9 rule it is 89%.
What is the VTU CGPA to percentage formula?
For the 2015, 2017 and 2018 schemes VTU uses percentage = (CGPA − 0.75) × 10, so a CGPA of 8.20 is 74.5%, the example in VTU's own regulations. The 2022 scheme regulations use CGPA × 10 instead, which makes 8.20 equal to 82%.
How do I convert CGPA to percentage in AKTU?
AKTU's revised B.Tech ordinance for 2018-19 states percentage = CGPA × 10. The original 2018-19 ordinance used (CGPA − 0.75) × 10, with the example (8.66 − 0.75) × 10 = 79.1%, so check which version your batch follows.
Is there a CGPA to percentage formula for Mumbai University?
Not any more. A University of Mumbai circular dated January 1, 2026 says the actual percentage should be calculated from the student's marks in all semesters, and it repealed the 2018 and 2019 conversion circulars. Add up your marks with the marks percentage calculator instead.
How do I convert a percentage to CGPA?
Reverse the formula. On CBSE's rule, divide by 9.5: 76% ÷ 9.5 = 8.0 CGPA. On a × 10 rule, 85% is a CGPA of 8.5. Choose Percentage → CGPA above to do this.
