If you are an engineering student at Mumbai University, you have seen CGPI on your marksheet. But what does it actually mean, how is it different from CGPA, and how do you convert it to a percentage?
What Is CGPI? (Full Form and Meaning)
CGPI stands for Cumulative Grade Performance Index. It is the grading metric used by Mumbai University’s Faculty of Technology (Engineering) to represent your overall academic performance across all completed semesters on a 10-point scale.
CGPI vs CGPA
| CGPI | CGPA | |
|---|---|---|
| Full Form | Cumulative Grade Performance Index | Cumulative Grade Point Average |
| Used By | Engineering | Arts, Science, Commerce (CBCS) |
| Scale | 10-point | 10-point or 7-point |
| % Formula | Two-tier (different above/below 7) | 7.1 x CGPA + 11 |
Official CGPI to Percentage Formula
Per Circular No. Exam./Engg./7-20 of 2015:
- CGPI below 7: Percentage = 7.1 x CGPI + 12 (rounded up)
- CGPI 7 or above: Percentage = 7.4 x CGPI + 12 (rounded up)
Conversion Table
| CGPI | Formula | Percentage |
|---|---|---|
| 6.0 | 7.1 x 6.0 + 12 | 55% |
| 6.5 | 7.1 x 6.5 + 12 | 59% |
| 7.0 | 7.4 x 7.0 + 12 | 64% |
| 7.5 | 7.4 x 7.5 + 12 | 68% |
| 8.0 | 7.4 x 8.0 + 12 | 72% |
| 8.5 | 7.4 x 8.5 + 12 | 75% |
| 9.0 | 7.4 x 9.0 + 12 | 79% |
| 9.5 | 7.4 x 9.5 + 12 | 83% |
What Is a Good CGPI?
| CGPI Range | Equivalent % | Assessment |
|---|---|---|
| 9.0 - 10.0 | 79% - 86%+ | Excellent — top placements |
| 8.0 - 8.99 | 72% - 78% | Very Good — eligible for most companies |
| 7.0 - 7.99 | 64% - 71% | Good — meets most cutoffs (60%+) |
| 6.0 - 6.99 | 55% - 62% | Average — may miss some cutoffs |
| Below 6.0 | Below 55% | Below average |
Most placement drives set a cutoff of 60% (CGPI ~6.5-7.0). Top companies require 70%+ (CGPI 8.0+).
How Is CGPI Calculated?
CGPI = Sum(SGPI x Semester Credits) / Sum(Total Credits)
If all semesters have equal credits, it is the simple average of SGPIs.
