To sit in IIT Bombay’s Computer Science classroom in 2026, you had to finish among the top ~65 students in the entire country. That single number tells you almost everything about how brutal IIT admission has become. Here’s what five years of cutoff data actually reveals — and why “clearing” the exam is only the start.
1. The funnel nobody explains
Everyone talks about “cracking JEE.” Few show what happens after. Watch how the numbers collapse at each stage:
From exam hall to IIT seat — 2025
Each step is a fraction of the one above it.
Even after qualifying, only about 1 in 3 qualifiers actually lands an IIT seat. The exam doesn’t end the competition — it starts a second, harder one for rank.
2. More students are clearing it every year
The number of JEE Advanced qualifiers has climbed steadily — from ~42,000 in 2021 to nearly 57,000 in 2026 (more attempts, more seats). But seats grow slowly, so the rank pressure keeps rising.

3. The number that really matters: closing rank
“Qualifying marks” barely matter for the top seats. What matters is your All-India Rank versus a branch’s closing rank. And for CSE, the gap between IITs is staggering.

4. The top seat hasn’t budged
IIT Bombay CSE — India’s single most coveted engineering seat — has closed at almost the same rank three years running:

Rock steady in the mid-60s. If IIT Bombay CSE is the dream, the target has been clear and unchanging: be among the top ~65 in India.
What this means if you’re aiming for an IIT
- Chase rank, not the pass mark. Qualifying puts ~55,000 people in the pool for ~18,000 seats. Your rank is everything.
- Be flexible on college vs branch. Decide early: is it “CSE anywhere” or “any branch at a top IIT”? The two need very different ranks.
- Newer IITs are real IITs. A 3,000–6,000 rank can get you CSE at a new IIT — same degree, same JEE, growing campuses. Don’t dismiss them.
- Have a plan B. With ~18,000 IIT seats for lakhs of aspirants, strong NITs/IIITs deserve a place in your list, not an afterthought.
FAQ
What rank do you need for IIT Bombay CSE?
Around the top 65–67 All-India Rank (General) — it has closed at 67, 66 and 65 in 2024, 2025 and 2026. It’s the most competitive seat in the country.
How many students get into IITs?
About 18,160 B.Tech seats across 23 IITs (2025). Roughly 54,000 qualify JEE Advanced, so only about 1 in 3 qualifiers actually secures an IIT seat.
Is a rank of 5,000 enough for an IIT?
For CSE at a top IIT, no. But it can get you CSE at a newer IIT (closing ranks ~3,000–6,000) or other branches at mid-tier IITs. Rank strategy depends on your branch-vs-college priority.
Are IIT cutoffs getting tougher?
Qualifier numbers keep rising (42k → 57k in five years) while seats grow slowly, so competition for the top branches keeps intensifying — even as the top closing ranks stay roughly fixed.
