IPO price band, lot size and minimum investment: how to calculate

The terms

• Price band: the range within which you can bid, for example ₹665 to ₹700. The upper end (“cap”) cannot be more than 120% of the lower end (“floor”).
• Lot size: the minimum number of shares you must bid for. You bid in multiples of the lot.
• Cut-off price: you agree to pay the final issue price, whatever it turns out to be inside the band.

Minimum investment

Minimum = lot size × upper price band. Example: lot 21, upper band ₹700 → 21 × 700 = ₹14,700 for one lot.

Maximum for a retail investor

A retail application can be up to ₹2 lakh. Maximum lots = ₹2,00,000 ÷ (lot size × upper band), rounded down. With one lot at ₹14,700: 2,00,000 ÷ 14,700 = 13.6, so up to 13 lots (₹1,91,100).

What gets blocked

The amount blocked is calculated at the upper band even if the final price turns out lower; the difference is released after allotment.

Frequently asked questions

Does a higher bid price improve my chances?

For retail applicants bidding at cut-off is the safe choice; any bid at or above the final price is valid, and allotment among valid retail bids is by lottery.
