What is IPO Lot Size?

When a company decides to list its shares on the stock market, it doesn’t sell them one by one. Instead, it offers them in fixed groups called IPO lot sizes.

Think of it like this — if a company is offering its shares to the public, it bundles them in packets, and each packet has a fixed number of shares. You can’t buy less than that. So, if the lot size in IPO is 100 shares and each share costs ₹100, you’ll need ₹10,000 to buy one lot.

This simple rule helps standardize the process for everyone. Whether you’re a small retail investor or a big institution, the IPO lot size ensures that everyone applies in multiples of the same basic unit.

Why IPO Lot Size Matters

The IPO lot size may sound technical, but it actually protects the interests of investors and keeps the system organized.

For everyday investors, the minimum lot size in IPO ensures they can participate without needing large sums of money. For companies, it helps distribute shares fairly among all types of investors — retail, high-net-worth individuals (HNIs), and institutions.

Without this structure, large investors could buy up a major chunk of the issue, leaving little room for small participants. Having a defined lot size in IPO keeps the game fair and accessible. It’s the reason even someone investing ₹10,000 can stand alongside major investors during an IPO.

Minimum vs. Maximum Lot Size

Every IPO specifies two important things — the minimum and maximum lot size.

The minimum lot size is the smallest number of shares you can apply for. On the other hand, the maximum lot size in IPO sets a limit on how many lots retail investors can apply for — capped so that their total investment doesn’t exceed ₹2 lakh, as per SEBI’s rules.

Let’s take an example. Suppose an IPO has a lot size of 100 shares priced at ₹100 each. That means one lot costs ₹10,000. A retail investor can apply for up to 13 lots, which comes to ₹1.3 lakh. If they want to apply for more, they move into the HNI category.

This structure gives everyone clarity — how much to invest, how many lots to apply for, and where they fit in the investor categories.

How is Lot Size Decided in an IPO

The lot size in IPO isn’t picked at random. It’s carefully decided by the company and its merchant bankers, keeping SEBI guidelines in mind.

A few key factors influence the decision:

• The price band of the IPO
  
• The total number of shares being issued
  
• The company’s valuation and investor demand
  
• The goal of keeping the minimum investment value affordable, usually between ₹10,000 and ₹15,000

For instance, if the share price is high, the IPO lot size will be smaller so that retail investors can still participate. If the share price is low, the lot size might be bigger to keep the overall investment amount consistent.

In short, the lot size is set thoughtfully — to balance affordability for investors and the company’s fundraising needs.

How to Calculate Minimum Investment in an IPO

Once you know the IPO lot size and the share price, calculating your investment becomes very simple.

Minimum Investment = Lot Size × Price per Share

For example, if the lot size in IPO is 50 shares and each share costs ₹200, your minimum investment will be ₹10,000.

Knowing this helps you plan your budget before applying. You can decide how many lots to bid for depending on how much you want to invest — whether you’re testing the waters with one lot or applying for a few more to increase your chances.

Example of Lot Size from Recent IPOs

Here are some real examples of lot size from popular IPOs in India. They show how different companies fix their lot sizes based on their pricing:

• LIC IPO – Lot size: 15 shares | Price band: ₹902–₹949 | Minimum investment: around ₹14,235
  
• Zomato IPO – Lot size: 195 shares | Price band: ₹72–₹76 | Minimum investment: around ₹14,820
  
• Nykaa IPO – Lot size: 12 shares | Price band: ₹1,085–₹1,125 | Minimum investment: around ₹13,500

Each company sets its own lot size depending on its valuation and market strategy. The key is to keep the entry point within reach for small investors while keeping the issue attractive for larger participants.

FAQ’s

Q1. Can I apply for more than one lot?

Yes, you can. Investors are allowed to apply for multiple lots as long as the total amount stays within ₹2 lakh under the retail category.

Q2. What happens if the IPO is oversubscribed?

If more people apply than the total number of shares available, allotment is done through a computerized lottery. Applying for multiple lots can improve your chances slightly, but it doesn’t guarantee an allotment.

Q3. Is the lot size the same for all IPOs?

No. The IPO lot size varies from company to company. It depends on share price, valuation, and total issue size.

Q4. Who decides the lot size?

The company, along with its merchant bankers, decides the lot size in IPO in line with SEBI’s regulations.
