CGPA to Percentage: The Complete Guide for Indian Students (2026)
There is no single CGPA-to-percentage formula in India. Here is what actually decides yours — and how to get the correct number.
· Verified against official sources
Almost every website tells you to multiply your CGPA by 9.5. For most university-level programmes in India, that answer is simply wrong. The ×9.5 rule comes from CBSE Class 10 — it was never meant for engineering colleges or state universities.
The truth is that India has ~1,000 universities but only about five distinct formula patterns. Once you know which pattern your university uses, the conversion is exact. This guide covers all five, with real examples, and a calculator that already knows the correct formula for 40+ universities.
The 5 formula patterns (this is the whole story)
1. `CGPA × 9.5` — CBSE, UGC generic, Delhi University (CBCS), Bharathiar. Safe for many general-degree boards, wrong for most engineering universities.
2. `CGPA × 10` — Anna University, KTU, VIT, SRM, BITS, Manipal, Osmania and many more. The most common university formula.
3. `(CGPA − 0.75) × 10` — VTU (older schemes), AKTU, SPPU, JNTU (R16+), MAKAUT. The 0.75 offset aligns a scale that starts at 4.0.
4. `(CGPA − 0.5) × 10` — GTU, University of Kerala, MG University.
5. `7.1 × CGPA + 11` — Mumbai University's old outlier formula (now repealed — see its dedicated guide).
Why the ×9.5 myth is so costly
Take a CGPA of 8.5. Under ×9.5 you would report 80.75%. But if your university actually uses (CGPA − 0.75) × 10, your correct percentage is 77.5% — over 3% lower. On a job form or a college application with a 75% cut-off, that gap changes outcomes.
Always confirm the formula on your university's result portal or examination-cell circular. The calculator above is preset to the verified formula for each institution.

Frequently asked questions
Is CGPA × 9.5 correct for all universities?
No. ×9.5 is the CBSE/UGC general rule. Most engineering and many state universities use ×10 or a (CGPA − 0.75) × 10 formula. Using ×9.5 everywhere gives a wrong percentage.
How do I know which formula my university uses?
Check your university's examination-cell circular or result portal. This guide and its calculator list the verified formula for 40+ universities; ambiguous ones show every plausible option.
What is the difference between SGPA and CGPA?
SGPA is your grade-point average for one semester; CGPA is the cumulative average across all semesters, usually weighted by credits. See the SGPA vs CGPA guide.
