CGPA to Percentage Calculator
Convert CGPA to percentage — with the right formula
There is no single formula. Your university sets its own, and the difference between two common ones is several percent — enough to change which courses you qualify for. Pick the formula your institution uses, or enter it yourself, and the calculator shows its working.
If your marksheet or transcript already prints a percentage, use that figure on applications. A converted number is an estimate, and the institution reading it will use its own conversion.
The calculator needs JavaScript. The formula table below does the same arithmetic by hand.
The formulas, and who uses each
Each row converts the same CGPA a different way, so you can see what the choice is worth. Where your own university publishes a formula, that one governs — the others are here because a lot of institutions publish none and students are left guessing.
| Formula | Worked example | Used by |
|---|---|---|
| CGPA × 9.5 | Worked example: 8 → 76% | Used by: CBSE schools (Class X). Widely — and often wrongly — applied to university CGPAs as well. |
| CGPA × 10 | Worked example: 8 → 80% | Used by: Many Indian universities on a 10-point scale, and the assumption most overseas admissions offices start from. |
| (CGPA − 0.75) × 10 | Worked example: 8 → 72.5% | Used by: Used by universities that discount a grade point before scaling. Check your own examination regulations for the year you were admitted. |
| (CGPA − 0.5) × 10 | Worked example: 8 → 75% | Used by: The same idea with a smaller discount. Several technical universities publish one of these two; which applies to you is set by your regulations, not by your state. |
| GPA ÷ 4 × 100 | Worked example: 3.2 → 80% | Used by: A rough reading of a 4-point GPA. An approximation only — see the note below the table. |
| My university's own formula | No fixed example | Used by: Enter the multiplier and subtraction printed in your own regulations. This is the only one that is authoritative for you. |
About the 4-point GPA row
A US GPA is not a percentage divided down, and evaluators such as WES convert from the transcript itself rather than by formula. Treat that row as a rough orientation, never as a figure to quote — if a university has asked you for a GPA, ask them how they want it derived.

Send us your marksheet and we will tell you how the universities you are looking at are likely to read it, and whether you will need a formal evaluation.
CGPA and percentage questions
How do I convert CGPA to percentage?
Multiply your CGPA by the number your university publishes — most often 10, sometimes 9.5, and some universities subtract 0.5 or 0.75 first. Check your marksheet, your results portal or your examination regulations before choosing one, because the same CGPA can come out several percent apart.
8 CGPA is how much percentage?
It depends on the formula. ×10 gives 80%, ×9.5 gives 76%, and subtracting 0.75 first gives 72.5%. That is a spread of seven and a half percent on one CGPA, which is why this page asks which formula applies to you before it answers.
Is the ×9.5 formula correct for my degree?
Probably not. It comes from CBSE's school grading system, where it was derived from Class X marks, and it was never written for university CGPAs. It is the formula most calculators online use for everything, which is how it ended up on applications it does not belong on.
How do I convert a percentage back to CGPA?
Reverse the same formula — divide by the multiplier, then add back anything your university subtracts. Switch the direction at the top of the calculator and it does this for you. Be aware that a percentage rounded on your marksheet will not always return the exact CGPA you started from.
Do universities abroad accept CGPA, or do they want a percentage?
Most accept the transcript as it is issued and apply their own conversion, and many state a requirement in both. Some ask for an evaluation from a credential service. Send them what your institution printed rather than a figure you calculated, and let them convert it.
What is my CGPA on the 4-point GPA scale?
There is no reliable formula. A 4-point GPA is built from letter grades per course, so evaluators work from the transcript rather than from a single number. The row in the table above is a rough orientation only; if a university has asked for a GPA, ask them how they want it derived.
Which figure do I write on my application?
The one your institution prints. If your marksheet shows a percentage, use it. If it shows only a CGPA, submit the CGPA and attach the grading scheme your university publishes on the back of the transcript — that is what the admissions office reads it against.
