CGPA to Percentage Calculator
The 10-point CGPA scale has no single official percentage conversion. Every university uses its own formula — pick yours below, type your CGPA, and see exactly what the rule gives you.
Convert your CGPA
Select your university or board, then enter your CGPA.
What formula does each university use?
| University / board | Formula | Origin |
|---|---|---|
| CBSE (Class X & XII) | CGPA × 9.5 | Circular 24/2010 |
| Anna University | CGPA × 10 | R2021 regulations |
| VTU (2015–18 schemes) | (CGPA − 0.75) × 10 | VTU academic regulations |
| Mumbai University (CBCS era) | (CGPA × 7.1) + 11 | CBCS rules; reportedly replaced 2026 |
| AKTU | CGPA × 10 | University practice |
| Delhi University (general) | CGPA × 9.5 | Common approximation |
| HEC Pakistan | Band lookup (not a formula) | HEC Policy §13.1 |
Why there's no single CGPA-to-percentage formula
The UGC set the scale but not the conversion
India's University Grants Commission introduced the standardised 10-point CGPA in 2015 as part of the Choice-Based Credit System. The UGC defined the letter-grade-to-grade-point mapping (O = 10, A+ = 9, A = 8, … F = 0), the SGPA and CGPA calculation formulas, and the transcript format — and then stopped.No national percentage-conversion formula was ever published.The UGC framework defines the CGPA scale; each university defines its own percentage rule on top of it.
Where each formula came from
CBSE × 9.5 (Circular 24/2010): CBSE's own Class-X formula for converting 10-point CGPA to percentage. The reasoning given at the time was that 9.5 sits at the midpoint of the top band (90–100), making it a reasonable multiplier. This rule was never intended as a national standard, but it became the de facto default that most US admissions calculators use as a quick check.
Anna University × 10: Anna's R2021 regulations state that the percentage is "10 × CGPA". This is the same as scaling the 10-point CGPA directly to a percentage — simpler than CBSE's rule, and more lenient (an 8.0 becomes 80% rather than 76%).
VTU (CGPA − 0.75) × 10: VTU's 2015–18 regulations shifted the curve down by 7.5 percentage points. An 8.0 CGPA becomes 72.5% — significantly lower than CBSE or Anna would give for the same number. This is the rule most Karnataka engineering students see on their transcripts.
Mumbai University (× 7.1) + 11: Mumbai's CBCS-era rule used a different linear transformation: scale and shift. An 8.0 CGPA becomes 67.8% under this rule. This rule was reportedly replaced by a marks-based certificate starting around 2026 — if you're on the old CBCS scheme, your transcript legend will tell you which formula applies.
HEC Pakistan — banded lookup, not a formula: Pakistan's Higher Education Commission takes a different approach entirely. Each grade is paired with a band of percentages, and the official figure is the minimumof the band (per HEC §13.1). A 3.00 CGPA on the 4.0 scale maps to 71%, not the 75% that a "× 25" rule would give. There is no single formula to apply — you look up the band.
The risk of citing the wrong formula
Several converters that rank well for "CGPA to percentage" publish a band chart that contradicts the formula they open with. Worse, some attribute the wrong formula to the wrong university: VTU's (CGPA − 0.75) × 10 is sometimes labelled as "Anna University rule", which it is not. If your application form asks for a single percentage and you submit the wrong one, your record may be quietly devalued by a few percentage points — enough to slip below a scholarship cut-off without you knowing why.

Frequently asked questions
What is the official CGPA-to-percentage formula?+
There isn't one. The UGC introduced the 10-point CGPA scale in 2015 but never published a percentage-conversion formula. Every Indian board and university has its own rule — CBSE uses × 9.5 (Circular 24/2010), Anna University uses × 10, VTU uses (CGPA − 0.75) × 10 for its 2015–18 schemes. Pakistan's HEC doesn't use a formula at all — it uses banded grade-to-percentage lookup tables.
Which formula should I use?+
Use the one your own university publishes. Your transcript legend or exam-results page is the source of truth. If your university hasn't published a rule, use CBSE's × 9.5 as a default — it matches what most US admissions calculators produce. But label it as a reference, not an official figure.
Why do different converters give different answers for the same CGPA?+
Because they apply different rules to the same number. An 8.0 CGPA becomes 76% with CBSE × 9.5, 80% with Anna × 10, and 72.5% with VTU's (CGPA − 0.75) × 10. Three answers, three rules — none of them wrong if applied to the right transcript. The right number is the one tied to your school's policy.
Can I use a converted CGPA for US applications?+
No, not directly. Most US graduate programmes require a course-by-course credential evaluation from a NACES-member agency (WES, ECE, IEE, etc.). The evaluator reads your individual marks, not a single conversion. A self-converted percentage or CGPA is fine for self-assessment and shortlisting, but the official number on your application has to come from the evaluator.
What if my school uses a 4.0 or 5.0 scale, not 10-point?+
Pakistan's HEC standard is 4.0; many Chinese universities use 5.0. These aren't CGPA-to-percentage problems — they're GPA-to-percentage problems on a different scale. For Pakistan, the HEC publishes grade-to-percentage band tables (a 3.00 is paired with 71%, a 3.30 with 75%, etc.). For China, the convention varies by university — check your transcript legend.
