What Is Asset Under Management (AUM) And What It Means For Your Investments In 2026
What Is Asset Under Management (AUM)?
Asset Under Management (AUM) has become one of the most referenced metrics in the investment world. It serves as a key indicator of a fund's size and market presence. According to AMFI data, India's mutual fund industry’s AUM was INR 74.41 trillion as of June 2025, marking a transformative period in the country's investment space1.
The size of a fund, measured by its AUM, can provide valuable insights for investors. This blog explores what is asset under management, its implications for different investment vehicles, and how to properly weigh this metric when building your investment portfolio.
What Does Asset Under Management Mean?
AUM meaning in mutual funds refers to the overall market value of all financial assets that an investment company or financial institution manages for its clients. It is the cumulative value of investments under a particular fund manager or company.
Examples In Mutual Funds, PMS, AIFs
Mutual fund AUM India includes various investment vehicles:
1. Mutual Funds: The total value of investments across all schemes offered by a fund house
2. Portfolio Management Services (PMS): The combined value of all client portfolios managed by a portfolio manager
3. Alternative Investment Funds (AIFs): Total investments in private equity, hedge funds, and other alternative assets
4. Exchange-Traded Funds (ETFs): The market value of all assets held within the ETF
5. Wealth Management: Total client assets managed by wealth management firms
AUM varies significantly across different investment vehicles. AUM in PMS and AIFs is less compared to equity and debt funds due to their popularity. That is why understanding the importance of AUM in mutual funds is crucial.
HDFC Liquid Fund has an AUM of approximately INR 63,000+ crore as of September 2025. This substantial size makes it one of India's largest liquid funds. Many investors select this fund for short-term investment needs due to its liquidity and stability that come with such scale.
Why AUM Matters?
Indicator of Fund Popularity And trust
The size of a fund communicates valuable information about investor confidence. A larger AUM typically indicates:
- Strong investor trust in the fund house
- Greater resilience against large redemption pressures
- Access to better research teams, technology, and risk management systems
- Potential for lower expense ratios as fixed costs spread across a larger asset base
The top 10 mutual fund houses in India control more than 78% of the industry's total AUM, highlighting the concentration of investor trust among established players2.

Not Always Equal To Performance
The relationship between AUM size and fund performance contains important nuances. Large AUM does npt automatically translate to better returns:
- Smaller funds often showcase more agility in capitalising on market opportunities
- Very large funds may face "asset bloat," making it challenging to maintain high performance
- New funds with lower AUMs might be managed by talented fund managers who recently transitioned from other fund houses
AUM Trends In India
Growth Of Mutual Fund AUM Over Years
The trajectory of mutual fund AUM growth in India tells a remarkable story of industry expansion. From approximately INR 10 lakh crore in 2014, it grew to over INR 20 lakh crore in 2017. In 2020, it increased to INR 30 Lakh Crore3. In 2025, mutual fund AUM in India has boosted to INR 75 Lakh Crore.
This growth comes from several factors:
- Increasing financial awareness and literacy
- Shift from traditional savings instruments to market-linked investments
- Robust growth in Systematic Investment Plans (SIPs)
- Tax advantages associated with equity-linked saving schemes
- Enhanced accessibility through digital platforms
Retail Participation Rise
A particularly encouraging trend in the AUM growth in Indian mutual fund industry has been the increasing participation from retail investors. As of 2025, individual investors contribute approximately 61% of the industry's AUM, with retail investors accounting for 27.01%4.
Monthly SIP contributions have increased dramatically from approximately INR 26,000+ crore in May 2025. SIP AUM has also reached INR 14.61 lakh crore with 9.06 crore accounts5.
AUM vs Other Factors In Decision-Making
Returns, Expense Ratio, Portfolio Fit
While AUM provides valuable context, several other factors should also be considered:
1. AUM vs NAV difference: The Net Asset Value (NAV) is the per-unit value of a fund, whereas AUM reflects the total fund size. A higher NAV simply indicates accumulated growth since inception rather than superior quality.
2. Historical Returns: A fund's performance record across various market cycles often provides more valuable insights than its size alone.
3. Expense Ratio: Lower expense ratios directly impact net returns. Some smaller funds offer competitive expense ratios to attract investors.
4. Fund Manager Experience: The track record as well experience of the fund manager frequently outweighs the significance of fund size.
5. Portfolio Composition: The alignment between the fund's portfolio and your investment objectives and risk tolerance remains crucial.
Diversification Into Bonds And Alternatives
As investors mature in their investment journey, diversification beyond traditional mutual funds becomes increasingly important. The options include corporate bonds, debt funds, securitised debt instruments (SDIs), Real Estate Investment Trust (REIT), and more.
They have a negative correlation with equity funds and can offer diversification. However, always consider your risk tolerance level before making an investment.

You should adopt a balanced approach by evaluating returns, risk parameters, expense ratios, and portfolio fit, alongside AUM leads to more informed investment decisions.

AUM in mutual funds refers to the total market value of assets that a mutual fund or fund house manages on behalf of its investors.
