What Is Asset Under Management (AUM) and How To Calculate?

AUM is one of the most important metrics by which an investor or even a fund manager can judge a mutual fund over time. Read on to knwo more about what AUM in mutual fund is all about.

The total market value of the investments that a person or organisation manages on behalf of clients is known as assets under management (AUM). Companies use different definitions and calculations for assets under management. Several financial organisations factor cash, mutual funds, and bank deposits into their calculations of AUM. Others restrict it to funds that are managed at their discretion, in which case the investor gives the business permission to execute trades on their behalf. AUM is merely one factor that is considered when assessing a business or investment, overall. It is frequently taken into account together with management experience and performance. Investors, however, frequently view bigger investment inflows and AUM comparisons as a sign of quality and management expertise.

Impact of High AUM on Mutual Funds

The performance of Mutual Funds as measured by Assets Under Managed has a considerable impact on the financial market. It mostly depends on the fund houses; these businesses favour asset-rich enterprises since their clients favour them more. According to studies including 361 distinct equity funds in 2012, an AUM of less than Rs. 100 Crore was held by about 170 funds, of which 68% had AUM of less than Rs. 50 Crore. The total investment, however, was seen to increase from Rs. 530 crore in 2008 to Rs. 3841 crore in 2012. It demonstrated the possibility of the enormous expansion of Assets Under Managed for many organisations. A sizable asset fund might enable an asset manager to respond to shifting market possibilities by withdrawing or entering a specific venture when one presents itself. AUM is frequently used by investors to calculate performance and returns.

Importance of Asset Retention for Mutual Funds

Mutual funds are often long-term investments that are supposed to weather temporary ups and downs in the market. However if the fund keeps changing its asset composition then questions can be raised on whether the fund manager did the due diligence on the asset to begin with. Furthermore, buying and selling assets within a mutual fund, especially if they are not short term instruments (as int he case of overnight funds), may cause the funds to incur additional costs, thereby increasing their expense ratio.

Importance of AUM for Mutual Funds

Equity funds

In a perfect world, equities funds would provide a positive return and outperform the benchmark index during market highs and lows. Equity funds rely more on the asset manager’s ability to increase returns than they do on AUM. Total assets are one of the most important components of debt funds. Debt funds with more capital can distribute their costs across more participants, lowering fixed fund expenditures for each investment and raising returns.

Small-cap funds –

In general, small-cap funds do not rely heavily on assets under management. They only become a factor when the assets exceed a certain threshold, specifically when fund firms become the largest owners in a certain company. Small-cap funds frequently forego determining AUM and invest in SIPs rather than making bigger commitments. Also Read What are Small Cap Funds

Large-cap funds

The profits from the market’s yields are what large-cap funds rely on the most. Generally speaking, it is independent of the asset under management. When compared to organisations with greater assets, there are multiple instances where companies with smaller asset classes have generated much more revenues. It should be noted that larger returns generated by the corresponding Mutual Funds are not always correlated with higher asset values under management. The skill of the concerned portfolio manager and his capacity to achieve a competitive edge through well-informed predictions and wise investment decisions determine the performance of mutual funds.

AUM and Expense Ratio

The entire amount taken out of mutual fund returns is used to control smooth operations and make sure the funds are properly managed and administered. The expense ratio incurred, unique to each Mutual Fund, refers to these outlays. The expense ratio of a certain fund is influenced by the AUM since better administration of larger portfolios necessitates more time and effort. As a result, AUM and the expense ratio charged by mutual funds are directly related, suggesting that investing in mutual funds with a substantially bigger size will result in greater fees. However, according to SEBI standards, a mutual fund’s expenditure ratio must be precisely lower than its AUM.

Calculating AUM

An individual fund house may have a different method for calculating AUM. It often increases when an investment generates a steady, positive return over time. Good performance brings in more resources and investments, increasing the organisation’s overall asset base. The asset’s value does, however, decline each time the market falls or an investor redeems their shares. Depending on the market performance of the portfolio assets, the total value of assets under management changes constantly. At the conclusion of trading, when the market closes for the day, the net changes in the value of AUM are reflected. All investors need to know the asset management company’s overall valuation in order to calculate the rate of return on their investments in such mutual funds.


Market swings have a significant impact on the assets managed. The assets of the fund will increase when it generates returns and decrease when it suffers losses. This impacts the mutual fund fee as well. Lower expenses typically equate to lower value. For instance, let’s imagine that a mutual fund that has produced 10% returns has received a total investment of Rs. 10,000 from 100 investors. If so, Rs. 11,000 would be the fund’s AUM. After all is said and done, businesses determine the worth of the assets they manage using a variety of techniques. AUM is a great way to evaluate a fund’s popularity and performance, to put it briefly. Therefore, it shouldn’t influence whether or not you decide to invest.

Is AUM and NAV the same?

NAV displays the price at which a fund share may be purchased and sold. AUM, on the other hand, refers to the total amount of assets that a company or a person is in charge of managing. AUM is not expressed as a per-share figure like NAV is. It is advisable to concentrate on the AUM when investing.

How much AUM is good for a mutual fund?

The AUMs of various funds range from as little as 10 crores to as much as 30,000 crores. AUM and fund size are only significant for specific types of funds. A fund with a high AUM indicates greater investor engagement, and a fund with a low AUM indicates less investor interest in that fund.

Does AUM size matter in mutual funds?

A fund’s success is impacted by numerous factors e.g. whether you decide to invest in a small-cap or mid-cap fund. A mutual fund’s size, or assets under management (AUM),does help the firm to diversify their assets.

What is the importance of AUM in mutual funds?

A financial institution’s size can be determined by looking at the total value of its assets under management (AUM), which is also a key performance indicator.
