CGPA to percentage calculator

Formula (CGPA − 0.75) × 10 (8.40 − 0.75) × 10 = 76.50%

Not verified for your programme. Selected formula: General (10-point). Confirm it against your examination manual before putting the figure on a form.

Illustrative 10-point formula; no national conversion rule. Use it only if your own regulation specifies this formula.

Class labels are illustrative percentage bands, not an award of distinction or first class. Your programme may use CGPA thresholds, attempt limits and backlog conditions.

Every formula here is labelled either verified against an issuing document, or not verified. A verified badge is never shown without a real citation.

Why the same CGPA gives different percentages

The ×9.5 multiplier everyone repeats comes from CBSE, where it was derived from the average marks of high-scoring students. It was never a universal conversion rule, and applying it to an engineering CGPA can be badly wrong. Anna University’s University Departments R2015/R2018/R2019 circular specifies ×10. Mumbai’s cited 2019 CBCS circular specifies (CGPA × 7.1) + 11, then whole-percentage rounding. The same 8.4 produces 79.80%, 84.00% and 70.64% respectively.

This matters because the number goes onto a job application, a scholarship portal or a foreign university form, where a wrong figure is a misrepresentation rather than a rounding error. Pick your university from the dropdown, and if it is not listed, use the formula printed in your own examination ordinance rather than the general factor. If the figure you hold covers one semester rather than your whole degree, convert it on the SGPA to percentage page instead.

Every formula on this page is labelled one of two ways. Verified means someone read the issuing ordinance, circular or examination manual, and the page shows that document and the date it was read. Not verified means exactly that — the formula is in wide circulation but has not been checked against the source, so it carries no badge, no date and no link. A verified badge without a citation is worse than no claim at all, because you would then trust it.

Where a conversion is required and no official formula exists, most institutions accept the transcript itself along with the university grading key. Ask the receiving body which they prefer before converting anything by hand.

Three mistakes to avoid

01
Using ×9.5 for an engineering degree It is a CBSE school-board factor. Your university almost certainly publishes its own.
02
Ignoring the source rounding rule The main result shows the raw formula to two decimals. The cited Mumbai circular additionally rounds up to a whole percentage: 70.64% becomes 71%. Follow your applicable regulation or certificate.
03
Confusing SGPA with CGPA SGPA covers one semester. CGPA is the credit-weighted average across all semesters completed so far.

Frequently asked

Which formula should I use?
The one in your own university ordinance. Select your university above and check whether the formula is marked verified — if it is, the source document and the date it was read are linked under the result.
Is ×9.5 ever correct?
For CBSE Class X and XII, yes. For most Indian universities, no.
Can I convert a percentage back to CGPA?
Yes, using the inverse of the same formula. The percentage to CGPA page does exactly that, and refuses the cases where the formula cannot express your percentage.
How do I convert CGPA to a 4-point GPA for foreign applications?
Most universities want the transcript plus a WES or institution-specific evaluation, not a self-computed GPA. Convert only if the application explicitly asks for a number.
Why two decimal places?
They show the unrounded formula result without rounding up. Where an applicable circular specifies whole-percentage rounding, such as the cited Mumbai rule, that figure is shown separately.
