CGPA to Percentage Calculator
Enter the CGPA shown on your academic record, then choose the conversion rule that applies to your university, board or scheme. This calculator does not assume that ×9.5 or ×10 works for everyone.
Calculate your percentage
Use the formula stated on your transcript, regulation or official university circular.

Same CGPA, different formulas
This is a comparison only. Your percentage should come from the rule that applies to your academic record.
| Formula | Result for your CGPA |
|---|---|
| CGPA × 10 | Enter a CGPA above |
| CGPA × 9.5 | — |
| (CGPA − 0.75) × 10 | — |
| 7.25 × CGPA + 11 | — |
Which formula should you use?
Use the conversion rule attached to the record that issued your CGPA. The safest order is: your transcript or consolidated grade sheet, the academic regulation for your batch, an official examination circular, and then your university examination office. A formula from another university is not a substitute.
| Institution / rule | Use it when | Conversion |
|---|---|---|
| Anna University | Your applicable regulation states the consolidated-grade-sheet ×10 rule; R2025 is a verified example. | CGPA × 10 |
| CBSE Class X – Legacy CCE | Your result belongs to the former CCE CGPA system. | CGPA × 9.5 (indicative) |
| VTU | Your record is under the 2015, 2017 or 2018 scheme. | (CGPA − 0.75) × 10 |
| Mumbai University – 2026 onward | Your covered record falls under the current 2026 conversion procedure. | No CGPA-only formula |
| Mumbai University – historical 10-point CBCS | Your record is governed by the older Exam/Com/97 of 2018 CBCS rule. | 7.25 × CGPI + 11, then next full integer |
Verified rules included in this calculator
Anna University
Anna University’s Academic Regulations 2025 for affiliated B.E./B.Tech. programmes state that the percentage printed on the consolidated grade sheet is calculated as CGPA × 10. For example, 8.42 CGPA becomes 84.20%. An affiliated autonomous college may follow its own regulation, so the college’s academic rule still takes priority.
CBSE Class X – legacy CCE
CBSE’s former CCE documentation used 9.5 × CGPA as an indicative overall percentage. That is why the calculator labels this option as legacy CCE rather than “CBSE” without qualification. It should not be applied automatically to a modern marks-based CBSE result or to a university CGPA.
VTU 2015, 2017 and 2018 schemes
VTU’s official standard-formula page states (CGPA − 0.75) × 10 for these three schemes only. An 8.20 CGPA therefore gives 74.50%. If your VTU grade card belongs to another scheme, check that scheme before using the preset.
University of Mumbai
Mumbai University is a good example of why a single university name is not enough. Its historical 10-point CBCS circular for the stated Arts, Science, Commerce and Management scope used 7.25 × CGPI + 11 and rounded the result to the next full integer. The university issued a new conversion circular in 2026, so the calculator keeps the historical equation separate from the current option instead of silently applying the old formula.
Worked examples
8.42 CGPA with a ×10 rule
8.42 × 10 = 84.20%
Use this result only if your institution prescribes the ×10 conversion.
8.42 CGPA under legacy CBSE CCE
8.42 × 9.5 = 79.99%
This is the old CBSE indicative-equivalence calculation.
8.20 CGPA under the listed VTU schemes
(8.20 − 0.75) × 10 = 74.50%
This preset is restricted to VTU’s 2015, 2017 and 2018 schemes.
Quick reference: CGPA × 10 only
The values below are not a universal CGPA table. They apply only to a ×10 rule.
| CGPA | Percentage | CGPA | Percentage |
|---|---|---|---|
| 5.0 | 50% | 7.5 | 75% |
| 5.5 | 55% | 8.0 | 80% |
| 6.0 | 60% | 8.5 | 85% |
| 6.5 | 65% | 9.0 | 90% |
| 7.0 | 70% | 10.0 | 100% |
CGPA and percentage are not the same thing
CGPA is an index produced by a grading system. Percentage is a value on a 0–100 scale. A conversion equation is a rule defined by an institution; it does not recreate your original subject marks unless that institution specifically defines it that way. This is also why two valid formulas can give different percentages for the same CGPA.
When an official conversion certificate is required
A calculator result is useful for checking a form, but it may not be accepted as proof. Admissions offices, government recruitment bodies, foreign universities, credential evaluators and employers can ask for an official percentage conversion certificate or a percentage issued by the university.
If the application specifically asks for an official certificate, request it from the university, examination authority or college. CentralPortal calculates the selected rule; it does not issue academic certificates.
Common mistakes
- Using ×9.5 only because another calculator uses it by default.
- Using ×10 simply because the CGPA scale is out of 10.
- Ignoring the batch, regulation or scheme printed on the grade sheet.
- Using an older university circular for a newer record.
- Confusing CGPA and CGPI without checking the university’s terminology.
- Rounding the CGPA before applying the conversion formula.
- Treating an “indicative” or “approximate” conversion as original marks.
Frequently asked questions
How do I convert CGPA to percentage?
Find the conversion rule prescribed for your university, board, programme or batch. Then apply that rule to the CGPA printed on your academic record.
Is CGPA × 9.5 always correct?
No. It is a verified historical rule for CBSE’s legacy Class X CCE system and can also appear in other institution-specific regulations, but it is not a national formula.
Is CGPA × 10 always correct?
No. Anna University’s R2025 affiliated regulation is one verified ×10 example, but other institutions use different methods.
What percentage is 8 CGPA?
It depends on the rule. ×10 gives 80.00%, ×9.5 gives 76.00%, and the listed VTU formula gives 72.50%.
What percentage is 8.5 CGPA?
×10 gives 85.00%, ×9.5 gives 80.75%, and (CGPA − 0.75) × 10 gives 77.50%.
What percentage is 9 CGPA?
×10 gives 90.00%, ×9.5 gives 85.50%, and the listed VTU formula gives 82.50%.
What is the Anna University CGPA-to-percentage formula?
Anna University’s R2025 affiliated B.E./B.Tech. regulation states Percentage of Marks = CGPA × 10 for the consolidated grade sheet.
What is the VTU CGPA-to-percentage formula?
VTU’s official standard-formula page gives (CGPA − 0.75) × 10 for the 2015, 2017 and 2018 schemes. Do not assume the same rule applies to another VTU scheme.
Does CBSE use CGPA × 9.5?
CBSE used 9.5 × CGPA as an overall indicative percentage under the historical CCE grading system. It should not be treated as a universal current CBSE rule.
Can I use the calculator result for admissions or jobs?
Use it for reference unless the receiving organisation accepts a self-calculated conversion. If it asks for an official conversion certificate, obtain one from the issuing institution.
Sources and methodology
Institution-specific options are included only when the rule can be tied to an official university, board or examination source. Scheme and batch applicability still matters, so your academic record remains the final authority.
