CGPA to Percentage Calculator
Convert a 10-point CGPA to a percentage with the CBSE, multiply-by-10, VTU or a custom formula, and see the working.
What your result means
The result is an equivalent percentage, not your real marks. A CGPA is an average of grade points, and each grade covers a band of marks, so no formula can recover the exact marks you scored. It gives the figure your board or university agrees to use in place of marks.
| Formula | Who uses it (official source) | CGPA 8.2 becomes |
|---|---|---|
| CGPA × 9.5 | CBSE Class 10 results under the grading system, 2010 onwards (Circular 24/2010) | 77.9% |
| CGPA × 10 | Anna University (B.E./B.Tech. Regulations 2023) and many other universities | 82% |
| (CGPA − 0.75) × 10 | VTU 2015, 2017 and 2018 schemes, and its 2021 B.E./B.Tech. regulations | 74.5% |
| CGPA × your multiplier | Any university whose rule is a plain multiplier | Depends on the factor |
The same 8.2 gives three answers, from 74.5% to 82%. That gap is why you should use your own university’s rule. It is usually printed on the back of the grade card or in the regulations for your batch.
How CGPA to percentage is calculated
CGPA stands for Cumulative Grade Point Average: the average of your grade points across subjects or semesters, on a scale of 10. Each formula maps that average to a percentage.
- CBSE: percentage = CGPA × 9.5. A perfect 10 becomes 95%, not 100%. CBSE’s circular calls this an “indicative” percentage.
- Multiply by 10: percentage = CGPA × 10. A perfect 10 becomes 100%.
- VTU: percentage = (CGPA − 0.75) × 10. Take 0.75 off the CGPA first, then multiply by 10.
- Custom: percentage = CGPA × the multiplier you enter, from 1 to 20.
The result is shown to 2 decimal places, with the working underneath.
How to use the CGPA to percentage converter
- Enter your CGPA, from 0 to 10, with up to 2 decimals. It starts at 8.2.
- Choose the formula: CBSE (CGPA × 9.5), CGPA × 10 (Anna University and others), VTU, or “My university’s multiplier”.
- If you chose your own multiplier, enter it in Multiply CGPA by.
- Read the percentage and the working. It updates as you type.
If your CGPA is on a 4-point or 7-point scale, these formulas do not apply. Ask your university for its conversion rule.
Worked example
Ananya has a CGPA of 8.2. Here is what each formula gives:
- CBSE: 8.2 × 9.5 = 77.9%.
- Multiply by 10: 8.2 × 10 = 82%.
- VTU: 8.2 − 0.75 = 7.45, and 7.45 × 10 = 74.5%. VTU’s own regulations use this exact example.
- Custom, with a factor of 9.3: 8.2 × 9.3 = 76.26%.
If Ananya studied at Anna University, she should write 82% on forms. Using the CBSE formula would undersell her by 4.1 points, and using the VTU formula would undersell her by 7.5.
University rules we checked
We read each rule in the board’s or university’s own documents in October 2026. Rules change between schemes and batches, so match the document to your year of admission.
| Board or university | Rule in its documents | Applies to |
|---|---|---|
| CBSE | Overall indicative percentage = 9.5 × CGPA. Subject-wise = 9.5 × grade point of the subject. | Class 10 results under the grading scheme. The CGPA leaves out the additional 6th subject. |
| Anna University | % of Marks = CGPA × 10 | B.E./B.Tech. Academic Regulations 2023 (Revision 1, 2024), on the consolidated grade sheet |
| VTU | Percentage = (CGPA − 0.75) × 10 | 2015, 2017 and 2018 schemes per VTU’s “CGPA standard formula” page, and the 2021 B.E./B.Tech. regulations |
Many sites also list formulas for AICTE, the University of Mumbai and others. We could not find those rules in an official AICTE or University of Mumbai document, so they are not in the converter. Some of them add or subtract a constant, which the custom multiplier can’t do. Ask your university’s exam section for the rule printed on your grade card.
Why CBSE uses 9.5
From 2010, CBSE gave Class 10 results as grades and a CGPA instead of marks. Its Circular 24 of 28 May 2010 told schools that an “indicative equivalence” could be worked out as 9.5 × CGPA overall, or 9.5 × the grade point for one subject.
The circular states the rule without explaining the number. The explanation repeated on most education sites is that students in the top grade band (A1, 91 to 100 marks) averaged about 95 marks, and the top grade point is 10, so 95 ÷ 10 = 9.5. We could not find that reasoning in a CBSE document, so treat it as the common explanation rather than an official one.
CBSE went back to marks for Class 10 from the 2017-18 session, so newer marksheets show marks and need no conversion. The 9.5 rule belongs to CBSE. Do not use it for a university CGPA unless your university says so.
Is my CGPA first class?
Classes are set by each university, and some decide them from the CGPA itself. VTU’s 2021 B.E./B.Tech. regulations decide them from the converted percentage (M):
| Class (VTU 2021) | Converted percentage | CGPA needed |
|---|---|---|
| First Class with Distinction | 70% or more | 7.75 or more |
| First Class | 60% to under 70% | 6.75 to under 7.75 |
| Second Class | 50% to under 60% | 5.75 to under 6.75 |
| Pass Class | 42.5% to under 50% | 5.0 to under 5.75 |
So a VTU CGPA of 7.5 converts to 67.5%, which is First Class but not Distinction. At another university the same 7.5 can mean something else, so check your own regulations.
How a CGPA is worked out
Most universities use credits. Each course carries credits, and each grade has a grade point, such as 10 for the top grade. Your SGPA (Semester Grade Point Average) is the credit-weighted average of your grade points for one semester:
SGPA = sum of (credits × grade point) ÷ total credits
Say a semester has three courses: 4 credits with grade point 9, 3 credits with grade point 8 and 3 credits with grade point 7. That is (36 + 24 + 21) ÷ 10 = 8.1. Your CGPA is the same kind of average over all semesters so far, so a course with more credits counts for more. Universities also leave some courses out: Anna University’s 2023 regulations, for example, list several course types whose grades do not count towards the CGPA.
Using a converted percentage on forms
- Follow the form first: if the form gives its own conversion rule, use it, even if your university uses another.
- Otherwise use your university’s rule: look on the back of the grade card or in the regulations, and choose that formula here.
- Keep proof: some employers ask for a conversion certificate from the university, so it helps to get one early.
- Be consistent: use the same figure on every form, so your records match at document checks.
Government job forms also ask for your age as on a cut-off date, which our age calculator works out. For posts with a skill test, practise on our typing speed test.
Common conversions
| CGPA | CBSE (× 9.5) | × 10 | VTU |
|---|---|---|---|
| 9.5 | 90.25% | 95% | 87.5% |
| 9.0 | 85.5% | 90% | 82.5% |
| 8.5 | 80.75% | 85% | 77.5% |
| 8.2 | 77.9% | 82% | 74.5% |
| 8.0 | 76% | 80% | 72.5% |
| 7.5 | 71.25% | 75% | 67.5% |
| 7.0 | 66.5% | 70% | 62.5% |
| 6.5 | 61.75% | 65% | 57.5% |
To go the other way, from percentage to CGPA, reverse the same rule. With CBSE, 85.5% ÷ 9.5 = 9.0. With the multiply-by-10 rule, 82% ÷ 10 = 8.2. For VTU, divide by 10 and add 0.75. To work out a percentage from raw marks, use our percentage calculator.
Limitations
- Approximate: every formula gives an equivalent, not your actual marks.
- Rules change: the formula can differ between schemes or batches of the same university. Use the rule for your batch.
- Plain multipliers only: the custom option multiplies your CGPA. It can’t apply rules that add a constant or use slabs.
- Other scales: the converter is for 10-point CGPA only.

FAQ
CGPA to Percentage Calculator FAQs
How do I convert CGPA to percentage?
Multiply your CGPA by the factor your board or university uses. CBSE Class 10 under the grading scheme uses CGPA × 9.5, Anna University uses CGPA × 10, and VTU uses (CGPA − 0.75) × 10. The right formula is usually printed on your grade card or in your university’s regulations, so check there first.
Why do we multiply CGPA by 9.5?
The 9.5 factor is CBSE’s rule for Class 10 results under its grading scheme, set out in Circular 24 of 2010. The circular gives the formula but not the reason. The common explanation is that A1 students averaged about 95 marks and the top grade point is 10, so 95 ÷ 10 = 9.5. It does not apply to university CGPAs.
What is 8 CGPA in percentage?
8 CGPA is 76% with the CBSE formula (8 × 9.5), 80% with the multiply-by-10 rule used by Anna University, and 72.5% with the VTU formula ((8 − 0.75) × 10). The right answer depends on who gave you the CGPA. Use the formula printed on your grade card or in your university’s regulations, not the one that gives the highest number.
What is the VTU CGPA to percentage formula?
VTU uses percentage = (CGPA − 0.75) × 10. So a CGPA of 8.2 becomes 7.45 × 10 = 74.5%, which is the example in VTU’s own regulations. VTU lists this formula for its 2015, 2017 and 2018 schemes, and its 2021 B.E./B.Tech. regulations use it too. If you are in a later scheme, check its regulations.
How do I convert Anna University CGPA to percentage?
Anna University uses % of Marks = CGPA × 10, as stated in its B.E./B.Tech. Academic Regulations 2023. So a CGPA of 8.2 equals 82%, and 7.5 equals 75%. Choose “CGPA × 10” in the converter. If an employer asks for proof, you can request a conversion certificate from the university.
How do I convert percentage to CGPA?
Reverse the same rule your board or university uses. With CBSE, 85.5% ÷ 9.5 = 9.0 CGPA. With the multiply-by-10 rule, 82% ÷ 10 = 8.2. For VTU, divide by 10 and add 0.75, so 74.5% becomes 8.2. The result is only an equivalent, not an official CGPA, so quote the CGPA on your grade card wherever a form asks for it.
Is 7.5 CGPA first class?
At VTU, yes: 7.5 converts to 67.5%, and its 2021 regulations give First Class from 60% to under 70%, with Distinction at 70% or more. Under the CBSE rule 7.5 is 71.25%, and under the × 10 rule it is 75%. Other universities set classes in their own way, often from the CGPA itself, so check your regulations.
Which CGPA to percentage formula should I use on job forms?
Use the formula your own university or board prescribes, usually printed on the grade card or in its regulations. If the job form gives its own formula, follow the form. If neither is clear, enter your CGPA as it is and mention the scale, such as 8.2 out of 10. Keep the grade card ready, as employers may check it.
