CGPA to Percentage Calculator
Convert CGPA to percentage using CBSE, VTU, Anna University, Mumbai University, or your own formula. Works both ways — percentage to CGPA too.
CBSE official formula: Percentage = CGPA × 9.5
How CGPA to percentage conversion actually works
It's not one formula — it's one per university
CBSE and Delhi University both use Percentage = CGPA × 9.5 — sourced from CBSE's own published formula and DU's Examination Wing circular. Anna University uses a different multiplier entirely: CGPA × 10, per its official ACOE circular.
VTU's official formula (published on vtu.ac.in) isn't a plain multiplier at all — it's Percentage = (CGPA − 0.75) × 10. Mumbai University's is (CGPA × 7.1) + 11, from its CGPA/CGPI conversion circular. Selecting the wrong one silently gives you a wrong number, sometimes off by several percentage points.
Converting percentage back to CGPA
The reverse conversion runs the same formula backwards for whichever university you've selected — including correctly un-doing an offset like VTU's or Mumbai University's, not just dividing by a multiplier. Switch to "Percentage → CGPA" above to use it.
If your university isn't listed
Choose "Custom formula" and enter your own multiplier — it's printed on the back of most official marksheets, or published in your university's CGPA conversion circular. If your university uses an offset formula like VTU's rather than a plain multiplier, double-check the result against your university's own circular before using it officially.
Frequently asked questions
What is the formula to convert CGPA to percentage?
It depends on your university. CBSE and Delhi University both use Percentage = CGPA × 9.5 (a CGPA of 8.4 converts to 79.8%). Anna University uses CGPA × 10. Mumbai University uses (CGPA × 7.1) + 11. VTU uses a different shape entirely: (CGPA − 0.75) × 10. Select your university above to get the correct one automatically.
Is the CGPA × 9.5 formula applicable to all universities?
No — this is the single biggest mistake people make. ×9.5 is CBSE and Delhi University's formula specifically. VTU's official formula isn't even a simple multiplier — it subtracts 0.75 from your CGPA before multiplying by 10. Using the wrong formula on an official document (like a job application or an abroad-study eligibility form) can misstate your percentage by several points.
How do I convert percentage back to CGPA?
Reverse the same formula your university uses. For a pure multiplier formula like CBSE's, CGPA = Percentage ÷ 9.5. For formulas with an offset, like Mumbai University's, you first subtract the offset, then divide — the calculator above does this automatically when you switch to "Percentage → CGPA" mode.
What is considered a good CGPA out of 10?
A CGPA of 8 and above (equivalent to roughly 76-80%+ depending on your university's formula) is generally considered strong for most college admissions and job applications in India. Requirements vary significantly by institution and programme, so check specific eligibility criteria for your target college or employer.
Why do different universities use different CGPA formulas?
Each university sets its own grading policy based on how it distributes grade points across marks ranges, and some (like VTU) apply an offset before scaling rather than a flat multiplier. There is no single national standard, which is exactly why this calculator lets you pick your specific university rather than assuming one formula fits everyone.
