AUM in mutual fund refers to the total market value of assets managed by a fund house or investment manager on behalf of investors. The AUM long form is Assets Under Management. It includes all investments held within a fund, such as stocks, bonds, and other securities, and serves as an important indicator of a fund's size and popularity.
Assets Under Management (AUM) is one of the most commonly used metrics in the investment industry. It measures the total market value of investments that a mutual fund, asset management company, or portfolio manager oversees on behalf of investors.
In mutual funds, AUM includes all assets invested across securities such as equities, bonds, money market instruments, and fixed-income securities. The value of mutual funds AUM changes daily due to market movements, investor contributions through Systematic Investment Plans (SIPs), Lumpsum investments, and redemption requests.
Investors often use asset under management figures to assess a fund's scale and market presence. While a larger AUM can indicate investor confidence and operational stability, it does not automatically guarantee better returns.
The concept of asset under management mutual funds is particularly important because management fees, including the Expense Ratio, are often linked to the fund's total assets. Regulatory bodies such as SEBI require fund houses to disclose AUM regularly to maintain transparency for investors.
AUM is calculated by determining the total value of all assets held within a mutual fund at a given point in time.
Investors Contribute Capital Investors invest money through SIPs, Lumpsum investments, or other methods.
Fund Manager Invests the Money The collected capital is invested in stocks, bonds, ETFs, and other securities according to the fund's objective.
Asset Values Change Daily The market value of investments rises or falls depending on market conditions.
Investor Transactions Affect AUM New investments increase AUM, while redemptions decrease it.
Updated AUM is Reported The fund house calculates and publishes the latest AUM periodically.
For example, if a mutual fund holds investments worth ₹5,000 crore and receives an additional ₹500 crore from investors, the AUM increases accordingly. Likewise, market gains or losses directly impact the total value of assets under management.
Suppose a mutual fund scheme starts with 10,000 investors contributing a total of ₹100 crore.
The fund manager invests this amount in a diversified portfolio of stocks and bonds. Over time, the portfolio grows due to positive market performance and reaches ₹120 crore. Simultaneously, new investors add ₹30 crore to the scheme.
The fund's total AUM now becomes ₹150 crore.
If market conditions worsen or investors redeem their units, the AUM may decline. This example illustrates how mutual funds AUM reflects both investment performance and investor participation.

AUM provides valuable insights for both investors and fund managers.
Helps assess the size and scale of a mutual fund.

For investors evaluating multiple mutual funds, AUM can be considered alongside NAV, Expense Ratio, portfolio strategy, and diversification objectives.
While AUM is an important metric, it should not be the only factor used when selecting investments.
Large AUM does not guarantee superior returns.
Some large funds may face challenges deploying capital efficiently.
Smaller funds can sometimes outperform larger competitors.
AUM fluctuates with market conditions.
Investor inflows may temporarily inflate fund size.
It does not measure risk-adjusted performance.
Investors should evaluate factors such as fund strategy, historical consistency, expense ratio, and portfolio composition rather than relying solely on AUM.
Although both are important mutual fund metrics, AUM and NAV serve very different purposes.
Feature | AUM | NAV |
Full Form | Assets Under Management | Net Asset Value |
Purpose | Measures fund size | Measures per-unit value |
Calculation Basis | Total value of managed assets | Asset value divided by outstanding units |
Changes Due To | Market performance and investor flows | Changes in portfolio value |
Investor Use | Assess fund scale | Determine purchase and redemption price |
Unit of Measurement | Currency value (₹, crore, etc.) | Price per unit |
AUM tells investors how large a fund is, while NAV shows the value of each mutual fund unit. Both metrics provide useful but different insights into a fund's operations.
