IIT Bombay Cutoff 2026: JoSAA Counselling 2026 is underway, and here is the IIT Bombay JEE Advanced 2026 Round 1 Cutoff for all engineering branches and categories. Have a look at the complete branch-wise and category-wise cutoff, and find out which IIT Bombay branch you can get based on your JEE Advanced 2026 rank.
The Indian Institute of Technology (IIT) Bombay continues to be the most preferred engineering institute among JEE Advanced qualified students. Every year, lakhs of aspirants dream of securing admission to IIT Bombay, but only the top-ranked candidates manage to secure a seat during JoSAA Counselling.
The JoSAA Round 1 Cutoff 2026 gives students the first clear picture of the competition for every branch. Since IIT Bombay is the first preference for many top rankers, the Round 1 closing ranks are already very close to the final cutoffs in most branches.
In this article, we have analysed the IIT Bombay Round 1 Closing Rank for all major branches, including Computer Science, Electrical, Mechanical, Chemical, Civil, and other programmes. Along with the Gender-Neutral cutoff, we have also included the Female-only (Supernumerary) closing ranks to help candidates make better counselling decisions.
IIT Bombay Round 1 Cutoff 2026 Highlights
Some important observations from the Round 1 cutoff are:
- Computer Science and Engineering remains the most competitive programme.
- The OPEN category closing rank for CSE is only AIR 65.
- Electrical Engineering closed at AIR 400, making it the second most competitive core engineering branch.
- Mechanical Engineering closed at AIR 1852.
- Civil Engineering closed at AIR 4376.
- Among all programmes, Chemistry recorded the highest OPEN category closing rank of AIR 7099, making it comparatively easier to secure admission than other branches.
- Female-only seats significantly improve admission opportunities in several branches.
Overall, students with AIR below 2500 have multiple opportunities across IIT Bombay, while candidates above AIR 5000 generally have limited options in Round 1.

Branch-wise Analysis
Computer Science and Engineering
Computer Science continues to dominate student preference. The OPEN category closed at AIR 65, while the Female category closed at AIR 395. This indicates that only the top-performing candidates in JEE Advanced are able to secure admission to IIT Bombay CSE.
Electrical Engineering
Electrical Engineering remains one of the strongest choices after CSE. The OPEN closing rank is AIR 400, while Female candidates secured admission up to AIR 1600. The branch offers excellent placements and higher studies opportunities.
Mechanical Engineering
Mechanical Engineering continues to attract students interested in core engineering. The OPEN cutoff reached AIR 1852, whereas Female candidates got admission up to AIR 4903.
Chemical Engineering
Chemical Engineering closed at AIR 2750 in the OPEN category. Students interested in process industries, research, and interdisciplinary careers can consider this programme.
Aerospace Engineering
Aerospace Engineering closed at AIR 2593. Despite having fewer seats, IIT Bombay’s Aerospace department enjoys an excellent academic reputation.
Engineering Physics
Engineering Physics remains an attractive choice for students interested in research, quantum technologies, and higher education. The OPEN cutoff is AIR 1435.
Industrial Engineering and Operations Research
This branch continues to gain popularity due to its strong placement record and analytical curriculum. The OPEN closing rank reached AIR 834.
Economics
Economics is becoming increasingly popular among students interested in finance, consulting, and analytics. The OPEN cutoff closed at AIR 2270.
Civil Engineering
Civil Engineering recorded an OPEN closing rank of AIR 4376. Students looking for infrastructure, public sector, and higher education opportunities continue to prefer this programme.
Environmental Science & Engineering
Environmental Science closed at AIR 4979. The branch offers opportunities in sustainability, climate research, and environmental consulting.
Metallurgical Engineering & Materials Science
The OPEN cutoff reached AIR 3941. With increasing demand in the semiconductor and advanced material industries, this branch is gradually becoming more attractive.
Applied Geophysics and Chemistry
These programmes recorded comparatively higher closing ranks, making them accessible to students with AIR beyond 6000 in the OPEN category.
Category-wise Analysis
OPEN Category
The OPEN category is extremely competitive. CSE closed at AIR 65, while even Mechanical Engineering required an AIR below 2000.
EWS Category
The EWS cutoff follows a similar trend. CSE closed at AIR 20, while Electrical Engineering closed at AIR 105.
OBC-NCL Category
Candidates in the OBC-NCL category continue to have excellent opportunities across almost all branches. Electrical Engineering closed at AIR 279, while Mechanical Engineering closed at AIR 1038.
SC Category
Students securing AIR below 800 in the SC category have multiple branch options at IIT Bombay. CSE closed at AIR 33.
ST Category
The ST category offers comparatively broader opportunities, with CSE closing at AIR 16 and Mechanical Engineering at AIR 325.
Female Category Analysis
The Female-only Supernumerary seats considerably improve admission opportunities.
For example:
- CSE: AIR 395
- Electrical: AIR 1600
- Mechanical: AIR 4903
- Civil: AIR 8730
- Chemistry: AIR 16204
These additional seats provide deserving female candidates with significantly better counselling options without affecting Gender-Neutral seats.
Will the Cutoff Change in Later JoSAA Rounds?
One of the most common questions among students is whether they should expect major changes after Round 1.
For IIT Bombay, the answer is generally No.
Since most top-ranked students freeze their seats during the initial rounds, the movement after Round 1 is usually limited. Branches like Computer Science, Electrical Engineering and Mechanical Engineering witness only marginal changes.
Lower-demand branches such as Chemistry, Applied Geophysics or Environmental Science may experience relatively higher movement, but even there the difference is generally not very large.
Therefore, Round 1 cutoff should be considered one of the strongest indicators of the final admission trend.
Conclusion
The IIT Bombay JEE Advanced Round 1 Cutoff 2026 once again highlights the institute’s unmatched level of competition. Computer Science and Engineering remains the toughest branch, while Electrical, Mechanical and Engineering Physics continue to attract top-ranked candidates.
The good news for aspirants is that Round 1 already provides a reliable estimate of the final cutoff because IIT Bombay usually witnesses limited movement in later JoSAA rounds. Students participating in counselling should use these closing ranks to prepare realistic preference lists, while JEE Advanced 2027 aspirants can use them as target benchmarks during their preparation.
