Equal allocation is an IPO distribution method where the shares offered are distributed among investors as evenly as possible. In this method, the number of participants and the total number of lots available are usually more important than the amount requested by a single investor.
Equal allocation does not always mean that every investor will receive exactly the same number of lots. The final result may be affected by the IPO size, the number of participants, investor group allocation and the distribution rules stated in the prospectus. This content is for informational purposes only and does not constitute investment advice. Before participating in an IPO, investors should review the prospectus, price determination report and official announcements.
- In equal allocation, the number of participants is one of the key factors.
- The estimated number of lots can be calculated by dividing the available lots by the number of investors.
- Requesting a much higher amount does not always mean receiving more lots.
- The final allocation becomes clear only after the IPO demand collection and allocation process is completed.
What Does Equal Allocation Mean?
Equal allocation means that IPO shares are distributed among investors in a balanced way. This method is often used to allow individual investors to participate in IPOs more fairly, especially when demand is high.
In simple terms, there is a certain number of shares offered in the IPO, and these shares are distributed among the investors who participate. If demand is much higher than the number of shares available, investors may not receive all the lots they requested. In that case, the approximate number of lots per investor depends mainly on the number of participants and the number of shares available for distribution.
How Does Equal Allocation Work?
In equal allocation, the number of shares offered and the allocation reserved for each investor group are considered first. Then, the available number of lots is distributed among the participants in that investor group as evenly as possible.
For example, if a specific number of lots is reserved for individual investors and the number of participating individual investors is known, an approximate allocation can be estimated. However, the actual result may be affected by rounding rules, cancelled orders, minimum demand conditions and the distribution principles stated in the prospectus.
The prospectus is one of the most important official documents in an IPO process. Therefore, investors should always check the relevant prospectus and official announcements to understand the allocation method, participation conditions and distribution rules for each IPO.
Difference Between Equal Allocation and Proportional Allocation
Equal allocation and proportional allocation are two different methods used in IPO share distribution. One of the most common questions is whether requesting a higher amount always leads to receiving more lots.
| Topic | Equal Allocation | Proportional Allocation |
| Main logic | The aim is to distribute lots among participants as evenly as possible. | The requested amount or number of lots is more important in the allocation. |
| Main factor | The number of participants is more important. | The size of demand is more important. |
| Effect of higher demand | Requesting a very high amount may have limited effect. | Investors requesting higher amounts may receive more lots. |
| Lot estimate | An approximate estimate is easier if the participant count is known. | It is harder to estimate without total demand and the allocation ratio. |

How Many Lots Can You Receive in Equal Allocation?
The exact number of lots an investor will receive in equal allocation cannot be known in advance. However, making an approximate estimate is usually easier than in proportional allocation. The basic logic is to divide the number of lots available for distribution by the number of participating investors.
For example, if 20 million lots are reserved for individual investors and 1 million individual investors participate in the IPO, the approximate allocation may be around 20 lots per investor. This is only a simplified estimate. The actual result may change depending on the final number of participants and the distribution rules.
You can use the equal allocation calculator to estimate possible lot distribution. To compare different scenarios, the IPO lot calculator may also be useful.
Simple Equal Allocation Example
The following example is hypothetical and does not represent any specific IPO.
| Assumption | Value |
| Lots reserved for individual investors | 24,000,000 lots |
| Number of participating investors | 1,200,000 investors |
| Approximate lots per investor | 20 lots |
| Investor requesting 100 lots | May receive approximately 20 lots |
| Investor requesting 1,000 lots | May receive approximately 20 lots |
In this example, an investor requesting a higher number of lots and an investor requesting a lower number of lots may receive a similar allocation. This is because the main purpose of equal allocation is to distribute available shares among participants in a balanced way, rather than allocating shares mainly according to order size.
Equal Allocation Calculator
To estimate lot distribution in equal allocation, investors usually need the number of lots offered, the allocation reserved for individual investors and the estimated number of participants. These inputs can produce only an approximate scenario, not a guaranteed result.
You can use the equal allocation calculator to make an estimated calculation. To follow current IPOs and book-building dates, visit the IPO calendar.
What Should Investors Pay Attention To?
- Check whether the IPO uses equal allocation or proportional allocation.
- Follow the book-building start and end dates carefully.
- Check whether your bank or brokerage firm participates in the IPO.
- Review the prospectus, price determination report and company financials.
- Remember that the final number of lots is not known in advance.
- Do not make an IPO decision based only on the expected number of lots.

Frequently Asked Questions
Does equal allocation mean everyone receives the same number of lots?
The main idea is to distribute lots among participants as evenly as possible. However, the final result may vary depending on the number of participants, available lots and allocation rules.
Does requesting more money bring more lots in equal allocation?
In many cases, requesting a much higher amount may have limited effect. In equal allocation, the number of participants is usually more important than the size of each order. Still, each IPO’s distribution rules should be checked separately.
How is the number of lots estimated in equal allocation?
A simple estimate can be made by dividing the total number of lots reserved for individual investors by the number of participants. This is only an approximate calculation; the official result becomes clear after allocation is completed.
Is equal allocation better than proportional allocation?
There is no single answer. Equal allocation may look more balanced for smaller investors, while proportional allocation gives more weight to the size of demand. An investment decision should not be based only on the allocation method.
Where can I find the allocation method of an IPO?
The allocation method is usually stated in the IPO prospectus, intermediary institution announcements and IPO detail pages. Investors should check official documents and announcements for the most accurate information.
Conclusion
Equal allocation is an IPO distribution method that aims to allocate shares among participants as evenly as possible. In this method, the estimated number of lots mainly depends on the number of participants and the total number of lots available for distribution. The final result cannot be known in advance, but approximate estimates can be made with reasonable assumptions.
