India IPO season is on fire with record subscriptions. Recent IPOs like major tech listings saw 100x+ retail oversubscription.

Ready to run the numbers?
Why: Indian retail investors face record IPO oversubscriptions. Understanding your actual allotment probability — and whether the opportunity cost of blocked funds is worth the expected listing gain — is critical for informed decisions.
How: The calculator uses subscription data and category (retail/HNI/employee) to estimate allotment probability. Retail uses lottery (1 in X); HNI uses proportional. It also computes money blocked, opportunity cost, listing gain from GMP, and break-even GMP.

Quick Answer
IPO allotment is a lottery for retail when oversubscribed >1x. Each retail applicant gets max 1 lot. Probability = 1/subscription rate. HNI gets proportional allotment. GMP indicates expected listing gains.
📋 IPO Allotment Process — SEBI Rules
SEBI mandates different allotment rules for each category. Understanding these helps you set realistic expectations.
| Category | Subscription | Allotment Method |
|---|---|---|
| Retail | ≤1x | Guaranteed full allotment |
| Retail | >1x | Lottery — max 1 lot per applicant |
| HNI | Any | Proportional allotment |
| Employee | Any | Usually full allotment (lower subscription) |
🎲 Lottery vs Proportional Allotment
Retail: lottery when oversubscribed. HNI: proportional. If 100 people apply for 10 lots in retail, 10 get 1 lot each (1 in 10). In HNI, if you apply for 100 lots and 25x oversubscribed, you get 4 lots.
📈 GMP Explained
Grey Market Premium is the unofficial premium at which IPO shares trade before listing. It reflects market sentiment. 45% GMP on Rs 500 issue = expected listing ~Rs 725. GMP can collapse before listing.
📊 Recent IPO Performance
India IPO market 2025–2026: record subscriptions. Mainboard IPOs averaged 92% listing gain. SME IPOs saw 150x+ subscriptions.
🎯 Multiple Applications Strategy
Family members with separate PAN and Demat can apply. Each application gets a separate lottery ticket. 4 applications = 4x the chance in retail lottery. Legal and common strategy.
💰 Money Blocked & Opportunity Cost
ASBA blocks funds for 5–7 days. Funds stay in bank — no interest loss. But opportunity cost = what you could earn in FD (e.g., 7% per annum). Break-even GMP = GMP needed to cover that cost.
⚠️ IPO Risks
GMP can collapse. Allotment not guaranteed. Past performance does not guarantee future returns. Read DRHP. Compare valuations with peers.
