What is allotment ratio?

Allotment ratio is the share of applied shares or lots that are actually allocated.

Plain meaning

If an investor applies for 100 lots and receives 2 lots, the allotment ratio is 2%. It measures allocation efficiency, not the chance of receiving at least one lot.

Why it matters

It helps compare marginal efficiency across application tiers. A higher ratio does not automatically mean better risk-adjusted value.

How to read it

Read it with Pool A/B, clawback supply, oversubscription, expected lots and listing performance.

How it appears here

Allotment prediction tables show expected lots across tiers; allotment ratio can be inferred by dividing allocated lots by applied lots.

Common mistakes

Confusing allotment ratio with win rate.
Ignoring absolute lots and capital lock-up.
Assuming a high ratio means the IPO is attractive.
