What is Mutual Fund Unit and How does it Work?

When you invest in a mutual fund, you are not directly buying the stocks, bonds, or other securities held by the fund. Instead, your money is pooled with that of other investors, and you receive mutual fund units in return. These units represent your share in the mutual fund scheme.

But what exactly is a mutual fund unit? How is its value decided? How many units do you get when you invest through a SIP or lump sum? And most importantly, how can you purchase these units?

In this blog, we will break down mutual fund units in simple terms and explain how you can buy them, how units are allotted, and how their value changes over time.

What is a Mutual Fund Unit?

A mutual fund unit shows your overall share in the fund. The number of units you get depends on how much you invest and the fund’s NAV at the time of your investment. 

Example

Let’s say you invested Rs. 10,000 in a mutual fund scheme. The NAV of that particular fund is Rs. 50.

Then you will receive, 

Rs.10,000/Rs. 50 = 200 units. 

Now, if the NAV of this fund rises to Rs. 60, the value of your units will also rise and will become Rs. 60*200 units = Rs.12,000

If the NAV falls, the value of your investments will fall accordingly. 

How do Mutual Fund Units Work?

Each mutual fund scheme divides the total pool of assets into units and the number of units outstanding can be in crores for popular schemes. 

The fresh money that you invest will be allotted new units at that day’s NAV. 

When you redeem, the units are canceled and you receive cash equal to the current value of the units.

That’s a little different from the way shares work on the stock exchange, where prices move all the time through the trading day, according to the buyers and sellers. 

Mutual fund units, on the other hand, are priced once a day, after markets close, based on the value of everything the fund holds.

There is another interesting thing here: mutual funds do not have a fixed number of units like a company has a fixed number of shares (unless it is a closed-ended fund). 

Most funds in India are open-ended, meaning units can be created or cancelled continuously as investors enter or exit. This is also why open-ended funds are usually far more liquid and easier to buy or sell compared to closed-ended ones.

What is NAV and Why Does it Matter?

Net Asset Value, or NAV, is the price of one unit of a mutual fund. The formula for calculating NAV is as follows; 

Net Asset Value = (Total Assets – Total Liabilities) / Total Number of Units

All mutual funds in India declare their NAV at the end of each business day, and this is published on AMFI’s website as well as on the fund house’s own site. You can always check the previous day’s NAV before making a decision.

Now, why does NAV actually matter to you as an investor? 

First, it determines how many units you get when you invest. A lower NAV does not mean the fund is cheaper or of better value; it is just a different number of units for the same rupee amount. 

A common mistake newer investors make is assuming a fund with NAV of ₹20 is a better buy than one with NAV of ₹200. What matters is the growth rate of the NAV over time, not its absolute value on a given day.

Second, NAV is what determines your redemption amount. When you sell your units, you get paid based on that day’s NAV (or the next applicable one, depending on cut-off timings). 

Third, tracking NAV movement over months and years is how you judge whether a fund has performed well.

How to Purchase Mutual Fund Units 

Step 1: Complete your KYC

You start by completing your KYC. This is mandatory and involves submitting your PAN, address proof, and a photograph, either online through a KYC-registered agency or through the app or platform you’re using. 

Once that’s done, you need to link a bank account for payments and redemptions.

Step 2: Select Mode of Investing

From there, you can choose between two main routes of investing: a lump sum, where you put in a larger amount in one go, or a Systematic Investment Plan (SIP), where a fixed amount gets debited automatically every month. 

Most Indian investors, especially first-timers, usually prefer SIPs since it does not need to time the market and spreads out the investment.

Step 3: Decide the Type of Plan you Want to Invest In

You will also need to decide between a Direct plan and a Regular plan. Direct plans have lower expense ratios since there is no distributor commission involved, which means slightly better returns over the long run, though Regular plans come with the added benefit of advisory support if you are investing through an intermediary.

Step 4: Final Allotment of Units

Once your payment goes through, units get allotted to your folio based on that day’s NAV (assuming you have invested before the cut-off time, usually 3 PM for most equity and debt schemes). You will get a confirmation, and the units start reflecting in your account within a day or two.

Equity Shares vs Mutual Fund Units 

Basis	Equity Shares	Mutual Fund Units
Ownership	Represents direct ownership in a company	Represents your share in a mutual fund scheme
Investment	Money is invested directly in a specific company	Money is pooled and invested across multiple securities
Price	Share prices change continuously during market hours	Units are valued based on the applicable NAV
Management	Investor decides which stocks to buy and sell	Fund manager manages the portfolio
Diversification	Depends on the stocks selected by the investor	Usually provides diversification through multiple investments
Buying & Selling	Traded on stock exchanges through a broker	Purchased/redeemed through AMCs, MF platforms, brokers and other authorised channels

Where Can You Purchase Mutual Fund Units?

• Directly from the AMC: You could go directly through the AMC’s own website or app; this works well if you already know exactly which fund house and scheme you want.
• Dedicated MF Platforms: Alternatively, there are dedicated mutual fund platforms and apps that let you compare, track, and invest across multiple AMCs from a single dashboard.
• Brokers or Investment Apps: You can also invest through your existing broker or trading and investment app, since many of them now offer mutual fund investing alongside stocks and other instruments. 
• Banks/MFDs/RIAs: Then there are traditional routes like mutual fund distributors, banks, and registered investment advisers, useful if you’d rather have someone guide your fund selection based on your goals and risk profile. 

How are Mutual Fund Units Allocated?

Unit allocation is not instant in the way that, say, buying a stock is. When you place an investment order, your money does not automatically get converted into units the same second. Instead, it depends on when you invest relative to the fund’s cut-off time.

For most equity, hybrid, and debt schemes, if your application and funds are received before 3 PM on a business day, you get that day’s NAV. If it comes in after 3 PM, you are allotted units at the next business day’s NAV instead. 

For liquid and overnight funds, the rule is different since these are priced based on the previous day’s NAV in many cases.

Once the NAV for the relevant day is finalised, your units get computed and credited to your folio, and this usually reflects within one to three working days depending on the scheme type and how the payment was processed. 

You will get an email or SMS confirmation from the registrar (CAMS or KFintech, mostly) once the allotment is done.

Conclusion 

Mutual fund units might sound like a technical term, but once you understand how they work, a lot of other things get easy like why your investment value moves the way it does, why NAV is not a measure of cheapness, and why timing your purchase around cut-off hours can matter. 

At the end of the day, it is a simple system built to divide ownership among thousands of investors, and once you have grasped that, mutual fund investing feels a lot less intimidating.
