IIT Bombay Cutoff 2026: Branch-Wise Closing Ranks for Every Category (2023 to 2026 Trend)

1. IIT Bombay Cutoff 2026: Branch-Wise Closing Ranks

These are the final-round (Round 5) closing ranks from JoSAA 2026, the last JEE Advanced rank that got a seat in each program. All IIT seats are All India quota, so there is no home-state advantage at IIT Bombay. Programs are sorted from hardest to easiest to get.

Source: JoSAA 2026 Opening and Closing Ranks, Round 5 (final), josaa.admissions.nic.in. Ranks are JEE Advanced 2026 Common Rank List (CRL) ranks. Female-only seats include supernumerary seats.

The IIT Bombay CSE cutoff is the hardest seat in India. Only 67 JEE Advanced ranks fit inside it in 2026, and girls could get CSE through the female-only pool up to rank 395.

Female-only seats are much easier. For almost every program the female-only closing rank is two to six times the gender-neutral one, for example Mechanical Engineering at 4,903 against 1,900. If you are a girl, include both pools in your choice list. JoSAA considers you for both.

2. IIT Bombay Category-Wise Cutoff 2026 (OBC, EWS, SC, ST)

For reserved categories, JoSAA uses your category rank, not your CRL rank. So "OBC-NCL 1,048" means OBC-NCL category rank 1,048. These are gender-neutral seats in the final round.

The IIT Bombay CSE cutoff for OBC-NCL was category rank 62, for EWS 20, for SC 39 and for ST 16. For core branches the gap between categories is wider: Mechanical closed at OBC-NCL rank 1,048, EWS 452, SC 610 and ST 325.

3. IIT Bombay Cutoff Trend, 2023 to 2026

Final-round closing ranks for OPEN gender-neutral seats over four years. A smaller number means the program got harder to enter.

What the trend shows

• CSE is rock steady: 67, 68, 66 and 67. You need a top-70 rank, every year.
• Industrial Engineering and Operations Research got much harder: 1,726 in 2024, 1,273 in 2025 and 834 in 2026. Students are choosing it over core branches.
• Electrical Engineering is tightening: 481 in 2023, 411 in 2026.
• Mathematics (BS) keeps rising in demand: 1,704 in 2023, 1,042 in 2026.
• Mechanical Engineering became slightly easier: 1,736 in 2023, 1,900 in 2026.
• Civil, Chemical and Aerospace stayed in narrow bands: Civil 4,046 to 4,417, Chemical 2,464 to 2,833 and Aerospace 2,361 to 2,694.

4. Round 1 vs Final Round: How Much Did Cutoffs Move?

Many students fill a seat in Round 1 and wonder whether to wait for a better one. Here is how far IIT Bombay closing ranks moved between Round 1 and the final round in 2026 (OPEN, gender-neutral).

For the top programs the movement is tiny. CSE moved by 2 ranks and Electrical by 11. Only the last few programs, Environmental Science, Applied Geophysics and Chemistry, moved by 500 or more. If your rank is just outside one of those, it is worth choosing Float or Slide and waiting for later rounds. If you are outside CSE or Electrical in Round 1, a later round is very unlikely to change that.

5. Where India's Top Rankers Went in 2026

The official JEE Advanced 2026 report shows which IIT the top rankers actually joined. IIT Bombay leads at every level.

Source: JEE (Advanced) 2026 Report, Volume I, Joint Implementation Committee, IIT Roorkee, section 13.6 "Allotment of Top 5000 Rankers across the Institutes" (p. 501).

So more than two out of every three top-100 rankers chose IIT Bombay. IIT Bombay had 1,363 seats in 2026 and allotted 1,366 in the final round, 270 of them (19.77%) to women.

6. IIT Bombay vs Other Top IITs: CSE and Mechanical Cutoff 2026

Source: JoSAA 2026 Round 5 (final), OPEN gender-neutral, 4-year B.Tech programs.

The CSE gap is large: IIT Bombay CSE needed a rank about twice as good as IIT Delhi CSE and more than four times as good as IIT Kanpur CSE. In Mechanical, the top IITs sit much closer together.

7. What JEE Advanced Rank Do You Need for IIT Bombay?

Based on the 2026 final-round closing ranks (OPEN, gender-neutral). Find your rank's row: you could get each program in it whose closing rank is larger than your rank, plus every program in the rows below.

Cutoffs change a little every year, so treat a rank within about 5% of a closing rank as borderline, not safe. Our Smart List marks every option as Safe, Likely or Reach, tested on four years of official JoSAA results.

8. How to Read These Cutoffs Correctly

• It is your JEE Advanced rank that counts, not your JEE Main rank or percentile. JEE Main only decides whether you can sit JEE Advanced.
• OPEN ranks are CRL ranks; reserved categories use category ranks. An OBC-NCL student is compared on the OBC-NCL rank list.
• "Closing rank" is the last rank admitted in the final round. Anyone with a better (smaller) rank who chose that program got it.
• Female-only seats are an extra pool. Girls compete for both gender-neutral and female-only seats.
• IITs have no home-state quota. Every IIT Bombay seat is All India.
• Last year's cutoff is a guide, not a promise. Most core branches moved by a few hundred ranks a year, but IEOR and Mathematics moved by much more.
