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.
