Most first-time investors see two mutual fund options: one with a NAV of Rs 12 and another at Rs 350, and assume the cheaper one is the better deal. It feels logical. Buy low, right? But this thinking costs thousands of investors real returns every year because NAV in mutual funds does not work like a stock price.
Understanding what is NAV in mutual funds and how it works is one of the first things that separates informed investors from the crowd. Once you get it, you stop chasing "cheap" funds and start asking better questions about fund performance and manager quality.
In this article, you will learn exactly how NAV is calculated, why it changes daily, what it actually tells you about a fund, and the most common NAV misconceptions that trip up beginners. By the end, you will have a clear framework for using NAV as one data point in a smarter investment decision.
What Is NAV in Mutual Funds?
NAV stands for Net Asset Value. It is the price per unit of a mutual fund on any given day. Think of it as the per-unit price of the fund's total holdings after subtracting all liabilities.
The formula is straightforward:
NAV = (Total Assets of Fund - Total Liabilities) / Number of Units Outstanding
If a mutual fund holds stocks, bonds, and cash worth Rs 100 crore, and it has liabilities (expenses payable, management fees accrued) of Rs 2 crore, its net assets are Rs 98 crore. If there are 1 crore units outstanding, the NAV is Rs 98 per unit.
When you invest in a mutual fund through a SIP or lump sum, you are buying units at the current NAV. When you redeem, you sell those units back at the prevailing NAV. The gain or loss you make is the difference between your purchase NAV and your redemption NAV, multiplied by the number of units you hold.
SEBI mandates that all mutual funds in India calculate and publish their NAV at the end of every business day. For equity funds, the NAV is updated after market hours. For liquid funds, it may be updated multiple times per day. You can check any fund's daily NAV on AMFI's official website or directly on your fund house's app or portal.
Why NAV Matters for Your Investments
NAV matters because it is the actual transaction price you pay when you enter or exit a fund. It also forms the basis for calculating your portfolio value and compound returns over time.
It Sets Your Entry and Exit Price
When you place a purchase order for a mutual fund before the daily cut-off time (typically 3 PM for equity funds in India), your units are allotted at that day's end-of-day NAV. This is called forward pricing. You do not know the exact price when you submit the order, which is intentional and protects all investors equally by preventing manipulation based on intraday price movements.
It Reflects the Fund's Portfolio Value Daily
Every change in the market affects the fund's holdings, and therefore its NAV. On a day when Nifty 50 drops 2%, an equity fund investing in Nifty stocks will see its NAV fall by roughly 2% as well. On strong rally days, the NAV rises. This daily mark-to-market is what makes mutual funds transparent investments.
What NAV Does Not Tell You
Here is where most beginners go wrong. NAV alone does not tell you if a fund is good or cheap. A fund with NAV Rs 15 is not a better buy than one with NAV Rs 500, any more than a Rs 15 share is automatically better than a Rs 500 share. What determines your wealth is how many units you own and how much those units grow, not the starting face value of each unit.
How NAV Is Calculated Every Day
The calculation happens after markets close. Here is the step-by-step process every fund house in India follows:
Step 1: Mark All Holdings to Market
Every security the fund holds is valued at its closing market price for the day. If the fund owns shares of Infosys that closed at Rs 1,800, that price is used to value those specific holdings. Unlisted or thinly traded securities are valued using SEBI-approved valuation methodologies.
Step 2: Add Up Total Assets
Total assets include the market value of all equity, debt, gold, or other instruments the fund holds. Cash and cash equivalents are added at face value. Accrued interest on debt holdings is included for debt and hybrid funds. Dividends receivable are also part of total assets.
Step 3: Subtract Total Liabilities
Liabilities include expenses payable, management fees, custodian fees, registrar and transfer agent fees, and any redemptions pending settlement. The expense ratio you read about in a fund's fact sheet reflects these costs being deducted daily from the fund's assets. This is why a fund with a 2% expense ratio costs you meaningfully more than one with 0.5%, even if NAV looks identical today.
Step 4: Divide by Units Outstanding
The net asset figure is divided by the total number of units held by all investors to arrive at the per-unit NAV. As new investors buy in, new units are created. As investors redeem, units are cancelled. The NAV adjusts accordingly.
This daily process ensures every investor gets a fair and equal price based on actual market values. No investor gets preferential pricing regardless of the size of their investment.
Real Examples That Show NAV in Action
Example 1: Same Returns, Different NAVs
Suppose you invest Rs 10,000 in a Nifty 50 index fund when the NAV is Rs 100. You receive 100 units.
A friend also invests Rs 10,000 on the same day in a different Nifty 50 fund with NAV Rs 500. They receive 20 units.
One year later, both funds track the same index and deliver identical 15% returns. Your fund's NAV is now Rs 115 and your 100 units are worth Rs 11,500. Your friend's fund's NAV is Rs 575 and their 20 units are also worth Rs 11,500.
Same investment. Same return. Different NAV. Different number of units. Identical wealth outcome.
Example 2: The Low NAV Trap That Costs Thousands
An investor chooses Fund A (NAV Rs 18) over Fund B (NAV Rs 200) because Fund A feels "cheaper and has more room to grow." Over three years:
- Fund A delivers 6% CAGR. Rs 1 lakh grows to Rs 1,19,102.
- Fund B delivers 14% CAGR. Rs 1 lakh grows to Rs 1,48,154.
The low-NAV fund left Rs 29,000 on the table. What matters is the fund's portfolio quality, manager skill, and consistent performance record versus its benchmark, not the number printed on the NAV label.
What Real Investors Say
Here is what investors in communities like r/IndiaInvestments and r/MutualFundsIndia often say about NAV:
"I always pick funds with NAV under Rs 20. It feels like I'm getting more units for the same money, which has to be better in the long run. More units means more profit when the fund grows, right?"
This is the most widespread NAV myth. More units at a lower NAV do not create more wealth. Rs 10,000 invested at NAV Rs 10 gives you 1,000 units. Rs 10,000 at NAV Rs 500 gives you 20 units. If both funds grow 20%, you end up with Rs 12,000 in both cases. The number of units is mathematically irrelevant. Total value is what counts.
"I got confused when my fund's NAV dropped after a dividend was declared even though markets were up. Thought something was wrong with the fund."
This investor discovered the concept of ex-dividend NAV. When a mutual fund declares a dividend, it distributes part of its assets to investors, so the NAV drops by exactly the dividend amount. Your total wealth stays the same because you received cash equal to the NAV reduction. This is one reason why most seasoned investors prefer growth plans over dividend plans for long-term compounding, since dividends are taxed as income and interrupt the compounding cycle.
"Does a very high NAV mean a fund is overpriced and about to fall? I keep seeing funds at Rs 700 or Rs 900 and I assume they've run too far."
No. A high NAV simply reflects how long the fund has existed and how well it has performed. There is no ceiling on NAV. It will keep rising as long as the underlying portfolio grows. Thinking of a high NAV as "overpriced" confuses fund unit pricing with stock valuation. A stock can trade above intrinsic value, but a mutual fund unit is always priced at exactly the net value of what it owns.
Common Mistakes Investors Make With NAV
Mistake 1: Choosing Funds Based on Low NAV
This is the single most common error new investors make. A newly launched fund with NAV Rs 10 is not better value than a 10-year-old fund at Rs 800. The older fund's high NAV reflects its cumulative growth. You are buying a proportional share of the portfolio in either case.
Mistake 2: Confusing NAV Growth With Fund Performance
A fund's NAV can rise simply because markets went up broadly, not because the fund manager is skilled. Always compare NAV growth against the fund's benchmark index and peer funds in the same category. A fund that grew 12% while its benchmark rose 15% is actually underperforming despite showing a rising NAV chart.
Mistake 3: Ignoring the Cut-Off Time
Many investors do not realise that the NAV you transact at depends on when your order reaches the fund house and when your payment clears. For equity funds, the cut-off is 3 PM. Orders submitted after that time get the next business day's NAV. For liquid fund investments above Rs 2 lakh, same-day NAV requires both the transaction request and cleared funds before the cut-off. Missing by a few minutes can mean transacting at a different NAV than expected.
Mistake 4: Comparing NAVs Across Different Fund Categories
Comparing the NAV of a large-cap equity fund with a liquid fund or a gold ETF is meaningless. Each category moves for entirely different reasons, on different timelines, with different risk profiles. Always compare performance within a category and use percentage returns or CAGR, not raw NAV numbers.
Mistake 5: Thinking Dividend Plans Are Better Because NAV Looks Lower
After a dividend payout, the NAV drops by the distributed amount. Some investors see this as a "safer" or "more affordable" fund. In reality, you are receiving your own money back, and that money is taxed as income in your hands. For long-term wealth building and portfolio growth, growth plans almost always outperform dividend plans on an after-tax basis.
Frequently Asked Questions
What is NAV in a mutual fund in simple terms?
NAV, or Net Asset Value, is the price per unit of a mutual fund. It is calculated by dividing the fund's total net assets by the number of units outstanding. When you buy a mutual fund, you purchase units at the current NAV, and when you redeem, you receive money based on the NAV at the time of redemption.
Does a higher NAV mean a fund is more expensive to buy?
No. A higher NAV simply reflects how long the fund has existed and how much it has grown. Two investors putting the same amount of money into a low-NAV fund and a high-NAV fund will receive identical returns if both funds perform equally. The starting NAV level has no bearing on future growth potential.
Why does NAV fall after a dividend is declared?
When a fund distributes a dividend, it pays out a portion of its assets to unitholders. The fund's total assets shrink by the dividend amount, so the NAV falls by exactly that amount. Your total wealth does not change at the moment of declaration because you received cash equal to the NAV drop.
Is it better to invest in a mutual fund when NAV is low?
Only if the underlying portfolio is genuinely undervalued at that point in time. NAV drops when markets fall, which can be a good long-term entry opportunity. But choosing a fund simply because its NAV number is smaller than another fund's is not a valid investment strategy.
How often is NAV updated in India?
For most equity and debt mutual funds in India, NAV is updated once per business day after market close, typically by 9 PM. Liquid funds publish NAV multiple times a day. All NAVs for registered Indian mutual funds are available on the AMFI website.
Can a mutual fund's NAV go to zero?
In theory only if every single security in the fund became completely worthless simultaneously, which would require a total collapse of every company or government issuer in the portfolio. For diversified equity funds, this is practically impossible. For debt and liquid funds, the risk is even lower. NAV can fall significantly in a crash, but reaching zero requires catastrophic and unprecedented circumstances.
Key Takeaways
- NAV equals total fund assets minus liabilities, divided by units outstanding, published every business day after markets close
- A fund with a low NAV is not cheaper or better value than one with a high NAV
- Your wealth depends on total returns over time, not the face value of each unit you hold
- NAV drops after a dividend payout because assets leave the fund, but your overall position value stays the same at that moment
- Always compare fund performance using percentage returns versus benchmark, not raw NAV figures
- The expense ratio is deducted daily from fund assets, which is why it directly erodes NAV growth over time
- Growth plans compound your money more efficiently than dividend plans for long-term investors, because dividends are taxed and interrupt compounding
