About the IIT Bombay CGPA calculator
Indian Institute of Technology Bombay (IIT Bombay) sits on the Powai campus and uses the IIT-wide 10-point grading system where top performers earn O (10.0) or A+ (9.0) grades. CPI — cumulative performance index — drives placement shortlists, higher-study applications, and institute awards. This calculator prevents the common mistake of treating IIT Bombay grades like CBSE percentages or US 4.0 GPAs.

What IIT Bombay students should know
IIT Bombay's dense semester schedules mix lectures, tutorials, and labs — especially in engineering departments. Dual-degree and IDC programmes may have different credit patterns; pull credits from your ASC portal. Institute medals and Dean's List cut-offs reference CPI thresholds that change yearly — use this tool to track progress, not to guarantee an award.
How to use this calculator
- Pick Semester GPA and list subjects with credits from your IIT Bombay registration.
- Map each final letter to the 10-point table — O = 10.0 down to F = 0.0 below 40%.
- Use CGPA mode for cumulative CPI across multiple semesters — weight each term by credits completed.
- Cross-check with the IIT Bombay ASC portal before submitting scholarship or visa application forms.
IIT Bombay grading system
IIT Bombay assigns O = 10.0 (90–100), A+ = 9.0 (80–89), A = 8.0 (70–79), B+ = 7.0 (60–69), and F = 0.0 below 40%. A C grade (5.0 points) still passes but weakens placement profiles. Never divide CPI by 4 to get a US GPA — conversion requires institute-approved tables.
The math behind semester GPA and cumulative CGPA is the same across most universities — see our CGPA formula guide for a worked example. For broader planning tips, read the complete CGPA guide on the homepage.
Percentage conversion
Many students estimate (CPI / 10) × 100 for informal percentage. IIT Bombay official documents and WES evaluations may apply different formulas — provide your sealed transcript for certified conversions.
