⚡ Quick answer
An IPO price band is the range within which investors can submit bids in a book-built public issue. The lower end is the floor price and the upper end is the cap price. The IPO lot size is the minimum number of shares in one application unit, while the IPO issue size represents the total value or quantity of shares offered to the public through a fresh issue, an offer for sale or both.
Investor note
Key Takeaways
The floor price is the lowest permitted bid in the announced band. The cap price is the highest permitted bid. Cut-off does not mean a discount; it means accepting the final discovered issue price. Lot size determines the minimum number of shares in one application. Application amount equals lots multiplied by shares per lot multiplied by bid price. Total issue size can contain fresh issue, offer for sale or both. Fresh-issue proceeds generally go to the company after expenses. Offer-for-sale proceeds go to the selling shareholders. Issue size is not the same as market capitalisation. A low rupee share price does not automatically mean a cheap valuation. Oversubscription can reduce allotment even when an application is valid. Listing return must be measured after costs and tax.
Three figures appear in almost every IPO announcement: price band, lot size and issue size.
They are connected, but they answer different questions.
The price band tells investors where they can bid. The lot size tells investors how many shares make one application unit. The issue size tells investors how much capital or how many shares are being offered.
An investor who misunderstands these numbers can block the wrong amount, submit an invalid bid, confuse issue size with company valuation or calculate a misleading listing gain.

What Is an IPO Price Band?
In a book-built IPO, the company and its Book Running Lead Managers announce a range within which investors can submit bids.
💡 Real example
Simple example
Price band: ₹310–₹326 per share
Here:
₹310 is the floor price; ₹326 is the cap price; eligible bids must fall within the range.
SEBI’s investor education material explains that book building collects bids within a price band so market demand can be used for price discovery.
What Is the Floor Price?
The floor price is the minimum bid price.
In a ₹310–₹326 band:
Floor price = ₹310
A bid below ₹310 is outside the announced range.
What Is the Cap Price?
The cap price is the maximum permitted price in the band.
Cap price = ₹326
A bid above the cap is unnecessary because the final issue price cannot exceed the announced upper limit unless the band is formally revised.
Why Is a Price Band Used?
A price band helps the issuer understand:
- demand at different prices;
- institutional and retail interest;
- the price at which the issue can be subscribed;
- the final issue price that may be selected.
The price band is not proof that the shares are fairly valued.
Investors still need to analyse:
- revenue and profit;
- cash flow;
- debt;
- use of proceeds;
- promoter background;
- business risks;
- valuation relative to listed peers.
How Is the Price Band Evaluated?
The issuer and BRLMs can consider:
- financial performance;
- industry outlook;
- growth expectations;
- listed-peer valuations;
- recent private transactions;
- institutional feedback;
- overall market conditions;
- number of shares being offered.
Peer-Valuation Example
Suppose the issuer earns ₹20 per share.
At an issue price of ₹320:
P/E ratio = ₹320 ÷ ₹20 = 16
If comparable listed companies trade near 13 times earnings, investors need to understand why the IPO deserves a premium.
The comparison must account for differences in growth, debt, margins, governance and business model.
Price per Share Is Not Valuation
A ₹100 stock can be more expensive than a ₹1,000 stock when measured against earnings, cash flow or book value.
Do not treat the rupee price as the company’s total value.
What Is the Cut-Off Price?
Eligible retail investors are generally allowed to choose the cut-off option in a book-built IPO.
Cut-off means:
“I agree to apply at the final issue price discovered through book building.”
It does not mean:
- the lowest price;
- a discount;
- guaranteed allotment;
- guaranteed listing gain.
Cut-Off Example
Price band:
₹310–₹326
Final issue price:
₹322
A retail applicant who selected cut-off agrees to pay ₹322 per share if shares are allotted.
A bidder who entered ₹315 would generally not qualify if the final issue price is ₹322.
Why Is the Cap-Price Amount Blocked?
When the final issue price is unknown, the application may require funds based on the cap price.
Suppose:
- cap price: ₹326;
- lot size: 45 shares;
- final issue price: ₹322.
Amount blocked:
₹326 × 45 = ₹14,670
Amount required after allotment:
₹322 × 45 = ₹14,490
Excess released:
₹14,670 − ₹14,490 = ₹180
Can the Price Band Be Revised?
SEBI’s investor guidance states that the band can be revised during the issue, with the required extension of the bidding period.
Investors should verify:
- revised floor price;
- revised cap price;
- extended closing date;
- treatment of earlier bids;
- whether a bid needs modification.
Use the exchange, RHP, issuer announcement or authorised application platform rather than an old screenshot.
What Is IPO Lot Size?
The lot size is the minimum number of shares in one application unit.
Suppose:
Lot size = 45 shares
Permitted multiples can be:
- 1 lot = 45 shares;
- 2 lots = 90 shares;
- 3 lots = 135 shares;
- 4 lots = 180 shares.
An application for 50 shares would not match this lot structure.
Why Do IPOs Use Lot Sizes?
Lot sizes standardise:
- minimum application quantity;
- bid processing;
- investor categories;
- allotment;
- application amounts.
IPO Lot vs Post-Listing Trading
The IPO application lot applies during the public issue.
After a normal main-board equity listing, individual shares can generally be traded, subject to exchange rules.
SME-platform shares can have different market-lot requirements and risk characteristics. Investors should read the specific issue documents.
How to Calculate the Minimum Application Amount
The formula is:
Minimum application amount = Shares per lot × Bid price
Suppose:
- lot size: 45 shares;
- cap price: ₹326.
Minimum amount at the cap:
₹326 × 45 = ₹14,670
Minimum amount at the floor:
₹310 × 45 = ₹13,950
Multiple-Lot Calculation
| Lots | Shares | Amount at ₹326 |
|---|---|---|
| 1 | 45 | ₹14,670 |
| 2 | 90 | ₹29,340 |
| 3 | 135 | ₹44,010 |
| 5 | 225 | ₹73,350 |
| 10 | 450 | ₹1,46,700 |
The application must remain within the selected investor category and applicable limits.
Retail, NII and Application Categories
Common investor categories include:
- Retail Individual Investors;
- Non-Institutional Investors;
- Qualified Institutional Buyers;
- employees or shareholders where reservations are offered.
Retail Individual Investor
Under the established IPO framework, a retail application generally does not exceed ₹2 lakh.
Investors must verify the exact category definition in the current RHP because regulations can change.
Non-Institutional Investor
An application above the retail threshold can fall into the NII category.
Current issue structures commonly divide NII applications into:
- more than ₹2 lakh and up to ₹10 lakh;
- more than ₹10 lakh.
The RHP explains the exact allocation structure.
UPI Limit vs Retail Limit
SEBI’s investor education page currently states that eligible individual investors can use UPI for IPO applications up to ₹5 lakh per transaction.
This does not make every application up to ₹5 lakh a retail application.
For example:
- a ₹1.8 lakh bid may fall within retail;
- a ₹3 lakh bid can use eligible UPI processing but fall within NII.
Always distinguish between the payment limit and the investor-category threshold.
Does Applying for More Lots Improve Allotment?
Not always.
The result depends on:
- investor category;
- subscription level;
- valid applicants;
- available shares;
- basis-of-allotment rules.
In a heavily oversubscribed retail category, the process may aim to allot the minimum lot to the maximum possible number of successful applicants, subject to the applicable rules.
Applying for many lots may therefore not create a proportionately larger allotment.
Duplicate applications using the same PAN can be rejected where the rules do not permit them.
What Is IPO Issue Size?
Issue size describes the total public offer.
It can be expressed as:
- total rupee value;
- total shares;
- fresh-issue value;
- offer-for-sale value.
💡 Real example
fresh issue: ₹800 crore; offer for sale: ₹500 crore; total issue size: ₹1,300 crore.
Issue Size Formula
Total issue size = Fresh issue + Offer for sale
₹800 crore + ₹500 crore = ₹1,300 crore
Approximate Shares Offered
Suppose the final issue price is ₹325.
₹1,300 crore ÷ ₹325 = approximately 4 crore shares
This is a simplified calculation. The official offer document states the exact quantity, reservations and rounding.
What Is a Fresh Issue?
A fresh issue creates and sells new shares.
The proceeds, after issue expenses, generally go to the company.
Possible uses include:
- expansion;
- factories;
- debt repayment;
- working capital;
- technology;
- acquisitions;
- subsidiaries;
- general corporate purposes.
Fresh Issue and Dilution
Because new shares are created, the outstanding share count increases.
Existing shareholders own a smaller percentage unless they acquire additional shares.
Dilution can create value when the new capital produces profitable growth.
What Is an Offer for Sale?
In an OFS, existing shareholders sell shares to public investors.
Possible sellers include:
- promoters;
- private-equity investors;
- venture-capital investors;
- institutional shareholders.
The proceeds go to the selling shareholders, not to the company.
Is a Large OFS Automatically Negative?
No.
An OFS can provide liquidity, partial exit and broader public shareholding.
Investors should examine:
- who is selling;
- how much is being sold;
- ownership remaining after the issue;
- reason for sale;
- whether the company also receives fresh capital.
Issue Size vs Market Capitalisation
Issue size and market capitalisation are different.
Issue Size
The value of the shares offered through the IPO.
Market Capitalisation
The value of all outstanding shares at the issue price.
Formula:
Post-issue market capitalisation = Post-issue shares × Issue price
Suppose:
- post-issue shares: 20 crore;
- issue price: ₹325.
Market capitalisation:
20 crore × ₹325 = ₹6,500 crore
If the IPO issue size is ₹1,300 crore, the company is not valued at ₹1,300 crore. The IPO represents only part of the ownership.
Face Value vs Issue Price
Face value is the accounting denomination of the share.
Issue price is what IPO investors pay.
💡 Real example
face value: ₹10; issue price: ₹325.
The issue price is 32.5 times the face value.
This ratio does not reveal whether the share is cheap or expensive.
Valuation depends on business fundamentals.
Worked Example
Assume Sunrise Logistics Limited launches an IPO.
This is a fictional example.
Issue Details
- price band: ₹280–₹294;
- lot size: 51 shares;
- fresh issue: ₹600 crore;
- OFS: ₹300 crore;
- total issue size: ₹900 crore.
Minimum Application at the Cap
₹294 × 51 = ₹14,994
Two-Lot Application
Shares:
51 × 2 = 102
Amount:
₹294 × 102 = ₹29,988
Final Issue Price
Suppose the final price is ₹291.
For one allotted lot:
₹291 × 51 = ₹14,841
If ₹14,994 was blocked:
Excess released:
₹14,994 − ₹14,841 = ₹153
Fresh Issue and OFS Proportion
Fresh issue percentage:
₹600 crore ÷ ₹900 crore × 100 = 66.67%
OFS percentage:
₹300 crore ÷ ₹900 crore × 100 = 33.33%
Listing Return Example
Assume the investor receives 51 shares at ₹291 and sells at ₹324.
Gross gain per share:
₹324 − ₹291 = ₹33
Gross gain:
₹33 × 51 = ₹1,683
Gross return:
₹33 ÷ ₹291 × 100 ≈ 11.34%
This excludes brokerage, statutory charges, spread, slippage and tax.

How Lot Size Affects Portfolio Risk
Suppose:
- portfolio: ₹1,00,000;
- one IPO application: ₹15,000.
Application exposure:
₹15,000 ÷ ₹1,00,000 × 100 = 15%
For a ₹10,00,000 portfolio, the same application is only 1.5%.
One lot can therefore represent very different risk for different investors.
Do not use emergency funds, borrowed money or money required before the allotment and listing process is complete.
How Issue Size Affects Subscription Data
Subscription is often reported as a multiple of shares available.
Suppose:
- shares offered: 2 crore;
- valid bids: 10 crore.
Subscription:
10 crore ÷ 2 crore = 5 times
A small issue can show a large subscription multiple with lower absolute demand.
A larger issue may attract more money but show a lower multiple.
Subscription should be interpreted with:
- issue size;
- category demand;
- valuation;
- business quality;
- market conditions.

Common Mistakes
Confusing Price Band with Valuation
A low rupee price does not automatically mean a cheap company.
Believing Cut-Off Means Lowest Price
Cut-off means accepting the final discovered issue price.
Forgetting to Calculate at the Cap
The application can fail if sufficient funds are unavailable for the maximum block amount.
Applying for a Non-Multiple Quantity
The bid must follow the announced lot structure.
Assuming More Lots Always Improve Allotment
Heavily oversubscribed retail issues can limit the benefit of applying for additional lots.
Confusing Issue Size with Company Value
Issue size represents the offered portion, not the value of the entire company.
Ignoring the OFS Component
OFS proceeds go to selling shareholders.
Treating GMP as the Main Decision Tool
The grey market is unofficial and should not replace offer-document analysis.
Ignoring Costs and Tax
Gross listing gain is not the final net return.
