What are Units in Mutual Funds?

Unit in mutual funds refers to the smallest proportion of ownership an investor holds in a fund. When you invest in a mutual fund in India, your money is pooled with that of other investors to create a diversified portfolio of shares, bonds, or commodities. Each investor receives units that represent their proportional share in the fund.

Balance Units in Mutual Funds

A unit in a mutual fund signifies an investor's proportionate ownership in the fund's portfolio. When an individual invests in a mutual fund, they acquire units, each representing a share of the total assets of that particular scheme. After deducting any liabilities, the NAV (Net Asset Value) is calculated by dividing the fund's total assets by the units outstanding.

The NAV of units fluctuates as the value of the underlying assets changes, reflecting the performance of the securities held by the fund. Investors can purchase or redeem units at the prevailing NAV.

However, "balance units" refers to an investor's remaining units after a partial redemption, SIP investment, or switch transaction. For example, if an investor initially held 1,000 units and redeemed 400, the balance would be 600. The balance continues earning returns per the fund's NAV and remains part of the investor's active holdings.

In Systematic Investment Plans (SIPs), balance units gradually increase with each instalment, since new units are allotted at the NAV applicable on the SIP date. Conversely, when redemptions are made, the balance units decrease accordingly. This dynamic helps investors track their holdings' evolution and monitor portfolio growth or withdrawal effects.

Calculating Mutual Fund Units

Mutual funds pool money from multiple investors to invest in a diversified portfolio of securities. Each investor holds units that represent a proportionate share of the fund. The value of one unit is determined by the Net Asset Value (NAV), which reflects the per-unit worth of all the fund's assets after deducting liabilities.

Formula:

NAV per Unit = (Total Assets - Total Liabilities) / Total Number of Units

Example: Consider a mutual fund holding the following:

Asset Type Value (₹)
Stock A 15,00,000
Stock B 25,00,000
Stock C 10,00,000
Stock D 5,00,000
Corporate Bonds 5,00,000
Government Bonds 30,00,000
Cash Derivatives 8,00,000
Treasury Bills 7,00,000

If the fund has liabilities of ₹5 lakh, the total value of the fund is:

15+25+10+5+5+30+8+7-5=100 lakh (₹1 crore)

Assuming there are 1 lakh units outstanding, the NAV per unit would be:

NAV=1,00,00,000/1,00,000=100

When an investor decides to invest, the number of units they receive is calculated by dividing the investment amount by the NAV on that day.

Example: If an investor invests ₹10,000 in a fund with a NAV of ₹50, the units allotted would be:

Units=10,000/50=200

Investors should note that additional charges, such as transaction fees, may slightly reduce the units received. Entry loads were discontinued by SEBI in 2009; only nominal transaction or stamp-duty charges may apply.

In India, units are allotted based on the NAV of the day the application is processed, which depends on market hours and fund cut-off timings. This method allows investors to accurately track their holdings and monitor the growth of their investments over time.

Importance of Units in Mutual Funds

In mutual funds, "units" indicate an investor's proportional stake in the fund. When an individual invests, the money is converted into units according to the fund's Net Asset Value (NAV) at that specific time. These units play a crucial role in understanding and managing mutual fund investments.

  • Representation of Ownership: Each unit signifies the portion of the fund owned by the investor relative to the total assets managed by the fund. The more units an investor holds, the larger their share in the fund's overall portfolio.
  • Determination of Investment Value: The value of an investor's holdings is directly linked to the NAV of the units. Since NAV is calculated daily based on the current market value of the underlying securities, it reflects real-time changes in the fund's value. As a result, the investment's worth increases or decreases with market movements.
  • Performance Tracking and Transparency: Units enable investors to monitor their investment effectively. Observing the number of units held and their corresponding NAV can help assess returns, evaluate performance, and make informed decisions regarding future investments.
  • Redemption and Liquidity: An investor's units determine the amount received upon redemption. The redemption value is calculated by multiplying the units by the prevailing NAV, ensuring a transparent and straightforward exit process.

Types of Units in Mutual Funds

Mutual fund units can be classified based on the investment option the investor selects or the purchase method. Understanding these categories helps investors make informed decisions according to their financial goals and risk preferences. The main types of units are:

  1. Growth Units

    Growth units reinvest all profits earned by the mutual fund back into the scheme rather than distributing them as dividends. This reinvestment increases the units' Net Asset Value (NAV) over time. Investors in growth units benefit from the compounding effect, as reinvested profits contribute to long-term capital appreciation. This option generally suits investors seeking long-term capital appreciation rather than periodic income.

  2. Dividend Units (IDCW)

    Dividend units, called Income Distribution cum Capital Withdrawal (IDCW) units, provide investors with regular payouts from the fund's profits. These payouts can occur monthly, quarterly, or annually, depending on the fund's policy. After each distribution, the NAV of the units decreases, as the payout is made from the accumulated earnings of the fund. This option is preferred by investors looking for periodic income rather than capital growth.

  3. Direct Plan Units

    Direct plan units are purchased directly from the Asset Management Company (AMC) without involving any intermediary, distributor, or agent. Since no commission is paid to intermediaries, direct plans have lower expense ratios than regular plans. This lower cost structure can result in higher net returns over the long term. Direct plans are suitable for investors confident in independently selecting and managing their investments.

  4. Regular Plan Units

    Commissions included in the expense ratio are paid to distributors who guide and assist investors in selecting funds. These plans include a distribution fee or commission, slightly increasing the overall expense ratio. While this may reduce net returns compared to direct plans, regular plans are often preferred by investors who value professional advice and support in fund selection and management.

How to Buy Mutual Fund Units?

Investors have multiple ways to purchase mutual fund units, each designed to suit different financial goals, investment horizons, and risk preferences. Understanding the methods ensures efficient planning and disciplined investing.

  1. Lump-Sum Investment

    A lump-sum investment is a single contribution made to a mutual fund at one point. This approach is suitable for investors with a ready amount to invest who wish to start participating in a fund immediately. Lump-sum investments provide instant exposure to the fund's portfolio and market movements.

    Steps to Invest:

    • Choose a Mutual Fund: Identify a fund that matches your financial objectives, risk appetite, and investment horizon. Assess the fund's performance history, portfolio composition, and investment strategy
    • Complete KYC: Ensure your Know Your Customer (KYC) formalities are complete. SEBI's 2024 update shows that KYC requires PAN and Aadhaar verification and CKYC compliance
    • Submit Investment and Documentation: Provide the required application form and the investment amount. Payment can be made through cheque, online transfer, or other accepted modes
    • Unit Allocation: Once the investment is processed, units are allotted based on the fund's Net Asset Value (NAV) on the day the investment is made. The NAV reflects the per-unit value of the fund at that time.
  2. Systematic Investment Plan (SIP)

    A Systematic Investment Plan, commonly known as SIP, allows investors to contribute a fixed amount to a mutual fund at regular intervals, such as monthly, quarterly, or annually. This method promotes disciplined investing and helps mitigate market volatility by averaging the cost of units over time.

    Steps to Invest via SIP:

    • Select a Suitable Fund: Choose a mutual fund that offers SIP facilities and matches your investment goals. Consider past performance, risk profile, and suitability for regular investing.
    • Decide Investment Amount & Frequency: Determine how much to invest and how often. SIPs allow starting with small amounts, making them accessible to most investors.
    • Set Up Auto-Debit: Authorise automatic deductions from your bank account on selected dates to ensure timely investments without manual intervention.
    • Unit Allocation: Units are allotted based on the NAV on each SIP date. Regular investing helps average purchase costs and mitigates the impact of market fluctuations.

Difference Between Mutual Fund Units and Equity Shares

Equity shares and mutual fund units are two common investment options that allow individuals to participate in financial markets. They differ in ownership, risk, and management:

Aspect Equity Shares Mutual Fund Units
Ownership Direct ownership in a company may include voting rights Ownership in the fund's portfolio; no direct claim on individual assets
Risk & Returns Higher risk due to exposure to a single company; potential for higher returns Lower risk due to diversification; returns are generally more stable
Management Managed by the investor, who decides when to buy or sell Managed by professional fund managers on behalf of unit holders
NAV Consideration Not applicable Units are valued based on the Net Asset Value (NAV), which is determined daily by the Asset Management Company (AMC) and reflects the fund's overall portfolio.

Key Takeaways

Mutual fund units represent an investor's proportional ownership in a professionally managed and diversified portfolio, offering lower risk than direct equity investments. The value of each unit depends on the Net Asset Value (NAV), which changes daily based on the fund's performance. Units can differ by type, such as growth or dividend (IDCW), allowing investors to choose options that match their income needs and financial goals. Understanding how units differ from equity shares helps investors make informed decisions aligned with their risk appetite and investment horizon.

Frequently Asked Questions

  • What is a unit in mutual funds?

    A mutual fund unit represents an investor's proportional ownership in the fund's portfolio, determined by the Net Asset Value (NAV) per unit.
  • Is 1 unit equal to 1 share?

    No, a unit in a mutual fund is not equivalent to one share of a company. Each unit represents a portion of the fund’s overall portfolio, not direct ownership of individual securities.
  • Can I sell mutual fund units?

    Mutual fund units can be sold or redeemed at the prevailing NAV, subject to the fund's redemption policies.
  • What is the 7-5-3-1 rule in SIP?

    The 7-5-3-1 rule is a popular investor heuristic, not a SEBI-approved guideline. It suggests investing in equity-oriented mutual funds for at least 7 years, diversifying across 5 asset classes, and preparing for 3 challenging market phases. This rule serves as an informal framework to encourage disciplined investing.
