CGPA to percentage — the correct formula for every university
The reason a single "CGPA to percentage" answer is so confusing is that there is no single national formula — CBSE, Anna University, VTU, Mumbai University, AKTU and others each convert differently, and using the wrong one can shift your result by 5–10 marks. This calculator solves that: pick your university or board and it applies the correct formula automatically, then shows you exactly which formula it used.
University-wise conversion formulas
| University / Board | Formula | 8.5 CGPA = |
|---|---|---|
| CBSE | CGPA × 9.5 | 80.75% |
| Anna University | (CGPA − 0.5) × 10 | 80% |
| VTU (2021/2022/2025) | CGPA × 10 | 85% |
| VTU (2018 & earlier) | (CGPA − 0.75) × 10 | 77.5% |
| Mumbai University (general) | 7.1 × CGPA + 11 | 71.35% |
| Mumbai University (engineering) | 7.4 × CGPA + 12 | 74.9% |
| AKTU / UPTU | (CGPA − 0.75) × 10 | 77.5% |
| SPPU (Pune) | (CGPA − 0.75) × 10 | 77.5% |
| JNTUH | (CGPA − 0.5) × 10 | 80% |
| KTU (Kerala) | CGPA × 10 | 85% |
| UGC general | (CGPA − 0.75) × 10 | 77.5% |
The same 8.5 CGPA ranges from 71.35% to 85% depending on the institution — which is exactly why you must use your own university's rule.
The most common mistake
Students grab the popular CBSE ×9.5 factor and apply it to an engineering CGPA, or use ×10 when their scheme subtracts 0.75. On application forms, the boundary between First Class and Distinction is fixed, so a wrong factor can drop you into the wrong class or trigger a mismatch when a verifier recomputes it. Always confirm the formula on your marks card or your university's grading regulation.
