An IIT degree costs ₹10-12 lakh over 4 years. An NIT costs ₹5-6 lakh. An IIIT costs ₹8-10 lakh. The starting salaries are ₹18L, ₹10L, and ₹8L respectively. But ROI isn't just fees vs salary — it's fees vs the salary premium over your entire career. Here's the real math.
The Head-to-Head Comparison
📊 Key Metrics (2024 Data)
| Metric | IIT (Top 5) | IIT (Others) | NIT (Top 5) | NIT (Others) | IIIT | |--------|------------|-------------|------------|-------------|------| | Annual Fee | ₹2.5-3L | ₹2-2.5L | ₹1.25-1.5L | ₹1-1.25L | ₹2-2.5L | | 4-Year Total Fee | ₹10-12L | ₹8-10L | ₹5-6L | ₹4-5L | ₹8-10L | | Avg CTC (CSE) | ₹22-25L | ₹12-15L | ₹12-15L | ₹8-10L | ₹10-14L | | Avg CTC (Non-CSE) | ₹12-18L | ₹7-10L | ₹7-9L | ₹5-7L | ₹6-8L | | Placement Rate | 85-95% | 65-80% | 70-85% | 55-70% | 70-85% | | Median Package | ₹18L | ₹9L | ₹8L | ₹6L | ₹7L |
The Trench Truth: The "average CTC" at IITs is inflated by a few ₹1Cr+ international offers that go to 1-2% of students. The median package is the real number. At IIT Bombay, the average might be ₹22L but the median is ₹16L — meaning half the batch gets less than ₹16L. At NIT Trichy, average is ₹12L but median is ₹9L. Always look at median, not average, when making college decisions.

│ ROI = (₹35L − ₹10L) ÷ ₹10L = 2.5× │
│ │
│ IIT and top NITs have SIMILAR ROI (6.5×) │

20-Year Career Earnings (CSE Branch)
📊 Cumulative Earnings with Typical Growth
| Year | IIT (Top) | NIT (Top) | IIIT | Private (₹1L/yr fee) | |------|----------|----------|------|---------------------| | 0 (graduation) | −₹12L fee | −₹6L fee | −₹10L fee | −₹4L fee | | 5 | ₹78L | ₹39L | ₹25L | ₹20L | | 10 | ₹2.5Cr | ₹1.2Cr | ₹75L | ₹55L | | 15 | ₹6Cr | ₹3Cr | ₹1.8Cr | ₹1.3Cr | | 20 | ₹12Cr | ₹6Cr | ₹4Cr | ₹3Cr |
IIT graduates earn 2× more over 20 years due to higher starting salary + faster growth + better opportunities. The ₹6L fee difference at admission becomes a ₹6Cr career earnings difference.
Branch vs College: What Matters More?
📊 CSE at NIT vs Mechanical at IIT
| Option | Starting CTC | 5-Year CTC | 10-Year CTC | |--------|------------|-----------|------------| | CSE at NIT Trichy | ₹12L | ₹25L | ₹50L | | Mechanical at IIT Kharagpur | ₹8L | ₹14L | ₹25L | | CSE at IIIT Hyderabad | ₹14L | ₹28L | ₹55L |
CSE at a good NIT outearns Mechanical at an IIT within 3-5 years. Branch > College for earning potential.
Key Takeaways
- IIT and top NITs have similar ROI (~6.5×) — but IIT earns 2× more in absolute terms
- Median > Average — IIT averages are inflated by 1-2% outlier salaries
- CSE branch > IIT brand for earning potential — CSE at NIT beats Mechanical at IIT
- IIITs have lower ROI — high fees without matching placement levels
- 20-year career earnings favor IIT by ₹6Cr+ — the brand compounds

Frequently Asked Questions
Is CSE at NIT better than Mechanical at IIT? For earning potential, yes. CSE at a top NIT (Trichy, Surathkal, Warangal) outearns Mechanical at an IIT within 3-5 years. But IIT brand value helps in non-tech careers (consulting, finance, civil services).
What is the actual fee difference? IIT: ₹10-12L over 4 years. NIT: ₹5-6L. IIIT: ₹8-10L. Private: ₹4-12L depending on college. But scholarships and fee waivers are available for EWS/OBC/SC/ST categories at all government institutes.
Does the IIT brand matter after 5 years? Yes, significantly. IIT alumni networks open doors in consulting, finance, startups, and international roles. The brand compounds over a career — a ₹6L fee difference becomes a ₹6Cr earnings difference over 20 years.
Are IIITs worth it? Only top IIITs (Hyderabad, Delhi, Bangalore, Allahabad). Their CSE programs are strong with good placements. Lower IIITs have high fees without matching placement levels — poor ROI.
Should I choose branch or college? If you want a tech career: branch > college (CSE anywhere beats non-CSE at IIT). If you want consulting/finance/civil services: college > branch (IIT brand opens more doors regardless of branch).
