How IPO Allotment Chances Are Calculated
IPO allotment probability is calculated by dividing 1 by the subscription times for each category. For example, if retail subscription is 10x, the allotment chance is 1/10 = 10% — meaning approximately 10 out of every 100 retail applicants will receive allotment.
In oversubscribed IPOs, SEBI mandates that each retail applicant can receive a maximum of one lot. If the number of applicants exceeds available lots, allotment is done by computerized lottery. Applying for more lots does not increase your chances — each PAN gets equal probability.
Tip: Apply from multiple family members' demat accounts (different PANs) to increase your overall household probability of getting allotment.
How Allotment Works for Each Category
- Retail (RII): When oversubscribed, allotment is by computerised lottery at one lot per applicant. SEBI requires that, as far as possible, every applicant gets at least one lot — so if applicants outnumber available lots, a random draw decides who gets the single lot. Bidding for more lots does not improve your odds.
- S-HNI & B-HNI (NII): Allotment is proportionate — larger applications receive proportionally more shares, subject to a minimum-lot draw. SEBI splits NII into Small (₹2–10 lakh) and Big (above ₹10 lakh) sub-categories, each with its own reservation.
- QIB: Allotted on a proportionate basis by the merchant banker; anchor investors are carved out of the QIB portion a day before the issue opens.
- Employee / Shareholder: Where a reserved quota exists, it is usually under-subscribed, so allotment odds here are often the highest of any category.
What Affects Your Allotment Chances
- Oversubscription level — the single biggest factor. A 2x retail subscription means roughly a 1-in-2 chance; 20x means about 1-in-20.
- Category you apply in — retail lottery vs NII proportionate behave very differently at the same subscription level.
- Number of distinct PANs — each PAN is one independent lottery entry; only one application per PAN counts.
- Total issue size & lot count — more available lots means more winners in the retail draw.
