IPO Allotment Chance Calculator

Our calculator provides estimates based on historical patterns and mathematical formulas used by registrars. The actual allotment depends on final subscription numbers, which are known only after IPO closure. The calculator achieves approximately 80-85% accuracy in predicting directional trends (high/medium/low chances).

Retail category uses a lottery system where each application has equal chances regardless of investment amount (up to ₹2 lakh). This gives small investors the same probability as someone investing ₹2 lakh. Additionally, retail quota (35% of issue) typically has better success rates compared to HNI category (15% quota) which uses proportional allocation.

No, retail category follows an all-or-nothing approach. You either get the full lot you applied for or nothing at all. Partial allotment is only applicable in HNI category where proportional allocation is used. This is why it's important to apply for only the number of lots you can afford if fully allotted.

If any category (Retail/HNI/QIB) is undersubscribed, the unused shares can be allocated to oversubscribed categories. This spillover effect can improve allotment chances in popular categories. However, the primary allocation percentages (35% Retail, 15% HNI, 50% QIB) are maintained as much as possible.

The lottery is conducted electronically by the registrar using a computerized system. Each valid application is assigned a unique number, and winners are selected randomly. The process is overseen by stock exchange officials to ensure fairness. Multiple lottery rounds may be conducted if the first round doesn't allocate all available shares.

In retail category, applying for more lots doesn't increase your probability of selection (it's still one application). However, if selected, you'll get all the lots you applied for. In HNI category, higher investment amount increases your proportional share. Only apply for the number of lots you can afford and are comfortable holding.
