When you start investing in mutual funds, you often see terms and numbers that look confusing. One such number is AUM. You may notice that one mutual fund has an AUM of ₹500 crore, while another has ₹50,000 crore.So a question comes to mind: what is this number? does this number really matter for me as an investor, or is it just for display?
Understanding AUM in mutual funds helps you make more informed choices instead of blindly picking a fund just because it looks “big” or popular.
What does AUM mean in simple words?
AUM stands for Assets Under Management.
In simple language, it means the total money that investors have put into a mutual fund.
Think of it like this:
- Thousands of people invest money in a mutual fund
- All that money is added together
- That total amount is called the fund’s AUM
So if a mutual fund shows an AUM of ₹10,000 crore, it means investors together have invested ₹10,000 crore in that fund.
How does a mutual fund’s AUM increase or decrease?
AUM is not fixed. It keeps changing because of two main reasons:
- New investments or withdrawals by investors
- Market movement (share prices going up or down)
If more people invest and markets perform well, AUM goes up. If many investors withdraw or markets fall, AUM comes down. This number is not constant.
A simple real-life example
Suppose a mutual fund has:
- 1 lakh investors
- Each investor has invested around ₹1 lakh
That means:
- Total AUM = ₹1,00,000 × 1,00,000
- AUM = ₹1,000 crore
Now, if markets rise and the value grows by 10%, the AUM may become around ₹1,100 crore, even if no new investor joins.

Does AUM in mutual funds matter to investors?
The short answer is: yes, but not always in the same way.
AUM gives you context, not a final decision.
- Very low AUM may mean the fund is new or not trusted yet
- Very high AUM may mean the fund is popular and stable
- But a higher AUM does not guarantee better returns (in fact nothing in the stock market guarantee better returns)
What matters more is how the fund is managed, not just how big it is.

Large AUM vs Small AUM (simple comparison)
| Aspect | Large AUM fund | Small AUM fund |
|---|---|---|
| Stability | Usually more stable | Can be volatile |
| Flexibility | Less flexible in buying/selling stocks | More flexible |
| Risk of closure | Very low | Slightly higher |
| Suitable for | Conservative, long-term investors | Investors comfortable with some risk |
This comparison is especially useful for Indian investors choosing between popular funds and newer ones.
When beginners should care about AUM
As a beginner, you should look at AUM in these situations:
- Avoid extremely low AUM funds (for example, below ₹100–200 crore), unless you understand the risk
- Prefer moderate to large AUM funds when starting out
- Do not select a fund only because it has the highest AUM
- Use AUM as a supporting factor, not the main reason
In simple terms, AUM helps you judge whether a fund is widely used and stable, but it should not replace proper research.

Common beginner doubts (FAQs)
Is higher AUM always better?
No. Higher AUM does not mean higher returns. It only shows the size of the fund.
Can a low AUM fund still perform well?
Yes. Some small funds may perform very well, but they may carry higher risk.
Does AUM affect my returns directly?
No. Your returns depend on market performance and fund strategy, not directly on AUM.
Can AUM change every day?
Yes. AUM changes daily due to market movement and investor activity.
Should beginners ignore AUM completely?
No. Beginners should consider AUM, but not rely on it alone.
Final thoughts
AUM in mutual funds tells you how big a fund is, not how good it is. For Indian investors, especially beginners, AUM is a helpful indicator of stability and popularity, but it should always be checked along with other factors like fund type, goals, and time horizon.
