Quick Answer

The minimum amount needed to apply for an IPO in India depends on the IPO price and lot size. In most mainboard IPOs, one lot usually costs around ₹14,000 to ₹15,000. In SME IPOs, the minimum amount is higher because individual investors generally need to apply for 2 lots, with the application size above ₹2 lakh.

Many new investors ask, “Can I apply for an IPO with ₹5,000?” In most cases, the answer is no. IPO shares are not applied for one by one. They are offered in fixed lots. If one lot has 150 shares and the IPO price is ₹100, you need ₹15,000 to apply. This amount is blocked in your bank account when you apply and is deducted only if shares are allotted.

What Is IPO Minimum Investment?

The IPO minimum investment is the least amount you need to apply for shares in an IPO.

This amount is decided by two things:

IPO price
Lot size

Lot size means the minimum number of shares you must apply for. You cannot choose any number of shares in an IPO.

For example, if the IPO price is ₹100 and the lot size is 150 shares, the minimum amount will be:

150 × ₹100 = ₹15,000

So, you need ₹15,000 to apply for one lot.

You can check active IPOs and upcoming IPOs on the Alice Blue IPO page.

How IPO Minimum Investment Works

The company announces a price band

Most IPOs come with a price range. For example, the price band may be ₹95 to ₹100 per share.

Retail investors usually choose the cut-off price. This means you agree to buy shares at the final price fixed by the company.

The IPO has a fixed lot size

Every IPO has a lot size. If the lot size is 150 shares, you can apply for 150, 300, 450 shares and so on.

You cannot apply for only 10 or 20 shares if the lot size is 150.

Your application amount is calculated

The formula is:

IPO application amount = IPO price × Lot size

Example:

₹100 × 150 shares = ₹15,000

This is the amount needed for one lot.

The money is blocked in your bank account

When you apply for an IPO, the money is not taken immediately.

It is only blocked in your bank account through ASBA or UPI. ASBA means your bank keeps the amount aside until the IPO allotment is completed.

Money is deducted only if you get shares

If shares are allotted to you, the required amount is deducted from your bank account.

If you do not get allotment, the blocked amount is released.

Shares are credited to your Demat account

If you get allotment, the shares are credited to your Demat account before the listing date.

To apply for IPOs, you need a Demat account. You can open one through the Alice Blue free Demat account page.

Minimum Investment for Mainboard IPOs

Mainboard IPOs are IPOs of larger companies that list on NSE or BSE.

For most mainboard IPOs, the minimum investment is usually around ₹14,000 to ₹15,000 for one lot.

Example:

Details	Amount
IPO price	₹100
Lot size	150 shares
Minimum lot	1 lot
Amount needed	₹15,000

Mainboard IPOs are usually easier for beginners because the ticket size is smaller than SME IPOs.

Minimum Investment for SME IPOs

SME IPOs are IPOs of small and medium-sized companies.

In SME IPOs, individual investors generally need to apply for 2 lots, and the application size is above ₹2 lakh. NSE’s SME IPO circular also mentions that individual investors must apply for 2 lots with a minimum application size of ₹2 lakh. (NSE Archives)

Example:

Details	Amount
IPO price	₹250
Lot size	400 shares
Minimum lots	2 lots
Total shares	800 shares
Amount needed	₹2,00,000

SME IPOs are not always suitable for complete beginners. They need more money, and selling shares after listing may be harder if trading volume is low.

IPO UPI Limit vs Retail Investor Limit

This is a common confusion.

The UPI limit for IPO applications is ₹5 lakh per transaction for individual investors. SEBI’s investor page states that IPO applications through UPI are allowed up to ₹5 lakh per transaction. (SEBI Investor)

But the retail investor limit in a mainboard IPO is usually up to ₹2 lakh.

So, remember this simple difference:

Point	Meaning
Retail IPO limit	Usually up to ₹2 lakh
UPI IPO payment limit	Up to ₹5 lakh per transaction
Above ₹2 lakh	Usually falls under the non-institutional investor category
Above ₹5 lakh	UPI may not be used; ASBA route may be needed

For a beginner applying in the retail category, the main thing is simple: keep enough balance for the number of lots you apply for and approve the UPI mandate on time.

Practical Examples With Numbers

Example 1: Mainboard IPO

Assume a mainboard IPO has these details:

Particulars	Details
IPO price band	₹95 to ₹100
Cut-off price	₹100
Lot size	150 shares
Minimum lot	1 lot

Calculation:

₹100 × 150 shares = ₹15,000

So, you need ₹15,000 to apply for one lot.

If you apply for 3 lots:

₹100 × 450 shares = ₹45,000

But applying for more lots does not guarantee allotment. If the IPO gets high demand, allotment may happen through a lottery system.

Key Points to Know Before Applying

You must apply in lots
IPO shares cannot be applied for in any random number.
Lot size changes for every IPO
Always check the lot size before applying.
Mainboard IPOs need less money
Most mainboard IPOs usually need around ₹14,000 to ₹15,000 for one lot.
SME IPOs need more money
SME IPOs generally need above ₹2 lakh.
Money is blocked first
The money is deducted only if shares are allotted.
A Demat account is required
IPO shares are credited to your Demat account.

Benefits of Applying for IPOs

You can invest before listing

An IPO gives you a chance to apply for shares before the company gets listed on NSE or BSE.

Mainboard IPOs have a lower starting amount

Many mainboard IPOs allow retail investors to start with around ₹14,000 to ₹15,000.

Money is released if shares are not allotted

If you do not get shares, the blocked amount comes back to your bank account.

Some IPOs may list at a higher price

Some IPOs list above the issue price. This may give listing gains, but it is not guaranteed.

You can hold shares for the long term

If the business is steady and fairly priced, some investors may hold the shares after listing.

Risks Beginners Should Know

Allotment is not guaranteed

Even after applying correctly, you may not get shares if the IPO is oversubscribed.

Listing gains are not fixed

The stock can list below the IPO price. This means you may face a loss on listing day.

SME IPOs carry a higher risk

SME IPOs need more money and may have lower trading volume.

Hype can lead to wrong decisions

Do not apply only because the IPO is trending online.

Money stays blocked for a few days

Use only spare funds. Do not use money needed for rent, bills, fees, or daily expenses.

A high-priced IPO can affect returns

Even a good company may not give good returns if the IPO price is too high.

Tips for Beginners Before Applying

Start with mainboard IPOs before trying SME IPOs.
Check the IPO price and lot size first.
Use the cut-off price option while applying in retail mainboard IPOs.
Keep enough balance in your bank account.
Approve the UPI mandate before the deadline.
Read what the company does.
Check profit, revenue, debt, and valuation.
Do not apply with borrowed money.
Do not apply only for listing gains.
Track the allotment date and listing date.

You can also use the Alice Blue brokerage calculator to estimate trading costs after listing.

Mainboard IPO vs SME IPO

Factor	Mainboard IPO	SME IPO
Minimum amount	Usually ₹14,000–₹15,000	Usually above ₹2 lakh
Minimum lot	Usually 1 lot	Usually 2 lots
Company type	Larger companies	Small and medium companies
Suitable for	Beginners and regular investors	Investors with higher risk capacity
Liquidity	Usually better	Can be lower
Risk level	Moderate to high	Higher
Cut-off price option	Available for retail investors	Usually not available
Best use	Starting with IPO investing	For experienced investors

Beginners usually find mainboard IPOs easier because the amount is smaller and trading volume after listing is usually better.

Common Mistakes to Avoid

Thinking IPO shares can be bought one by one

IPO applications are made in lots. Always check the lot size.

Looking only at the IPO price

A ₹100 IPO does not mean you can apply with ₹100. You need money for the full lot.

Ignoring company details

Check the business, profit, debt, and purpose of the IPO.

Expecting sure listing gains

IPO returns are not fixed. The stock can list at a discount.

Applying for SME IPOs without understanding risk

SME IPOs need more capital and may be harder to sell after listing.

Missing UPI mandate approval

Your IPO application may fail if you do not approve the UPI mandate on time.

Using emergency money

Apply only with money you do not need for daily expenses.

Who Should Apply for IPOs?

IPO investing is better for people who can keep money aside for a few days without affecting daily expenses.

It may suit:

Beginners starting with mainboard IPOs
Long-term investors
Investors who can read basic company details
People who can wait for allotment and listing
Investors who understand the listing-day price movement

It may not suit:

People looking for fixed returns
Investors using borrowed money
Beginners are applying only because of hype
People who cannot keep money blocked
Investors who do not understand the company

Before applying, understand basic terms like Demat account, lot size, issue price, listing price, and allotment.

Conclusion

The minimum investment required to apply for an IPO in India depends on the IPO price and lot size. For most mainboard IPOs, one lot usually costs around ₹14,000 to ₹15,000. For SME IPOs, the minimum amount is higher and usually goes above ₹2 lakh.

Beginners should first understand lot size, issue price, allotment, UPI mandate, and Demat account requirements. IPOs can offer opportunities, but they also carry risk. Allotment is not guaranteed, and listing gains are never fixed.

Apply only after checking the company, the IPO price, and your own risk comfort.
