A reader wrote to HMA Wealth genuinely alarmed last month. He’d invested in two equity funds on the same day, one at a NAV of ₹18 and another at a NAV of ₹480, and assumed the ₹18 fund was obviously the better deal since it looked “cheaper.” Two years later, both funds had grown by roughly the same percentage, and he still couldn’t understand why the ₹480 one hadn’t become dramatically more expensive to buy more units of.

That confusion is one of the most common misunderstandings in Indian investing, and it all comes down to not actually knowing what is NAV in mutual funds and what it does and doesn’t tell you. Our guide on mutual funds for beginners is a good companion to this piece if you’re still getting comfortable with the basics.

What Is NAV in Mutual Funds, in Plain Terms?

NAV stands for Net Asset Value, and it’s simply the price of one unit of a mutual fund scheme on a given day. Every mutual fund divides its total holdings into units, and the NAV tells you what each unit is worth right now, based on the fund’s underlying assets.

The formula behind it is straightforward: NAV equals the fund’s total assets minus its liabilities, divided by the total number of units outstanding. As an illustrative example, a fund with ₹500 crore in assets, ₹5 crore in liabilities, and 10 crore units outstanding would have a NAV of roughly ₹49.50 per unit.

If you’re still fuzzy on how a mutual fund pools money in the first place, our guide on what SIP investing actually is is a useful starting point before this NAV-specific deep dive. Our broader guide on how to start investing covers the fundamentals of market-linked investing too, in case mutual funds are entirely new territory for you.

Why Does a Low NAV Not Actually Mean a Fund Is “Cheap”?

This is the exact mistake the reader from the intro made, and it’s genuinely one of the most common ones HMA Wealth sees. A fund’s NAV reflects the current value of its underlying holdings, not how good a deal it is or how much room it has to grow.

A new fund launched at ₹10 and an established fund trading at ₹500 can both be perfectly reasonable investments. What actually matters is the fund’s percentage growth over time, not the absolute rupee value of one unit. If you invest ₹10,000 in a fund at NAV ₹50, you get 200 units; invest the same ₹10,000 in a fund at NAV ₹40, you get 250 units instead, but your total investment value is identical either way.

A 10% rise takes the ₹50 NAV to ₹55 and the ₹40 NAV to ₹44, and your total investment value grows by exactly 10% in both cases regardless of the starting NAV. Our broader explainer on types of mutual funds is worth reading alongside this, since fund category matters far more to your actual returns than NAV ever will.

This is really the core of what is NAV in mutual funds and what it isn’t: it’s a unit price, not a quality score. Our guide on common investing mistakes covers this exact NAV misconception alongside several other errors beginners make early on.

How Is NAV Calculated Every Single Day?

Mutual fund NAV is calculated once per business day, after markets close, based on the closing prices of all the securities the fund holds. AMFI (the Association of Mutual Funds in India) and individual asset management companies publish updated NAVs for every scheme at the end of each trading day.

This is a key difference from stocks or ETFs, which trade continuously during market hours at live, constantly shifting prices. A regular open-ended mutual fund, by contrast, has exactly one NAV per day, calculated after the market closes and applicable to that day’s transactions depending on when you placed your order.

If you’re investing through a SIP specifically, our guide on the 15-15-15 rule is a useful companion read for thinking about long-term SIP targets without getting distracted by daily NAV movements along the way.

What Is the Cutoff Time, and Why Does It Decide Which Day’s NAV You Get?

This trips up a lot of new investors who submit an order and then get confused about which NAV actually applied. For most equity and debt mutual funds, the cutoff time for both purchases and redemptions is 3:00 PM on a business day; for liquid funds, it’s typically 1:30 PM.

Submit your order before the cutoff, and you generally get that same day’s NAV, provided your payment also clears in time. Submit after the cutoff, and your order rolls over to the next business day’s NAV instead. These cutoff times can be revised by SEBI or individual AMCs, so always confirm the current timing on your fund house’s own website before relying on same-day NAV for a time-sensitive transaction. Our guide on what SIP step-up actually means is worth pairing with this if you’re planning to increase your monthly investment amount over time, since the same cutoff logic applies to every incremental SIP instalment too.

Why Does a Falling NAV Confuse New Investors So Much?

Because a falling NAV instinctively feels like a loss, the same way a falling stock price does, when in reality it often means something completely different depending on context. There are three genuinely distinct reasons a NAV can drop, and conflating them is where most of the confusion comes from.

First, and most obviously, the fund’s underlying holdings can simply have lost value that day, a genuine market-driven decline. Second, and far less understood, a dividend or IDCW (Income Distribution cum Capital Withdrawal) payout reduces the NAV by exactly the amount distributed, even though you haven’t actually lost money since you received that amount in cash. Third, in the case of certain debt funds, a lower-than-expected security valuation adjustment can show up as a NAV dip without reflecting the broader market at all.

Our guide on which fund type actually delivers higher returns is worth a read here too, since understanding what drives a fund’s returns in the first place makes a short-term NAV dip far less alarming when you actually see one. This is also precisely why learning what is NAV in mutual funds properly, rather than skimming the definition, saves you from reacting emotionally to a perfectly normal daily fluctuation.

Our guide on how to file your ITR online in India is also worth bookmarking, since any dividend or IDCW payout that affects your NAV also needs to be declared correctly at tax time.

Does a Rising NAV Always Mean the Fund Is Performing Well?

Not necessarily, and this is the flip side of the same misunderstanding. A fund’s NAV can rise purely because the broader market it’s invested in rose that day, which says nothing about whether the fund manager is actually outperforming their benchmark or peers.

The number that genuinely matters for judging performance is the fund’s percentage return over a meaningful period, ideally compared against its benchmark index and category average, not the absolute NAV figure on any single day. Our explainer on understanding CAGR covers how to measure this kind of annualised return properly, which is a far more useful comparison tool than NAV ever is. Our guide on the best ETFs to invest in India is worth a look too, since it shows the same percentage-return comparison applied to a different fund structure.

How Does NAV Affect How Many Units You Actually Get?

This is where NAV genuinely does matter practically, just not in the way most beginners assume. The NAV on the day your order is processed determines exactly how many units you receive for your invested amount; a lower NAV gets you more units, and a higher NAV gets you fewer, for the same rupee amount invested.

This matters most for SIP investors, since your fixed monthly amount buys more units when the NAV is temporarily lower (during a market dip) and fewer units when the NAV is higher. This is the mechanism behind rupee cost averaging, and it’s precisely why a falling NAV during a SIP tenure isn’t something to panic about; it’s quietly working in your favour by buying you more units at a lower cost.

Our comparison of SIP versus lumpsum investing covers this rupee cost averaging benefit in more depth if you’re deciding how to structure your own investment amount.

Our guide on the 1% rule is a useful companion here too, for thinking about position sizing more broadly once you understand how unit accumulation actually works.

How Is NAV Different From a Stock’s Market Price?

A stock’s price moves continuously throughout the trading day based on live buying and selling on the exchange, visible in real time on any trading app. A mutual fund’s NAV, by contrast, is calculated just once per day, after the market closes, and reflects the value of the entire underlying portfolio rather than a single security being traded.

If you’re also investing in ETFs, which do trade continuously like stocks despite being fund structures, our guide on what ETFs actually are in India explains this distinction clearly, since ETF units have both a real-time market price and a NAV, which can occasionally diverge slightly. Our guide on ETFs versus mutual funds covers this pricing difference in more depth if you’re deciding between the two structures.

What Mistakes Do New Investors Make Around NAV?

• Assuming a lower NAV means a cheaper or better investment, when it’s simply the per-unit price of that fund’s current holdings
• Panicking over a NAV drop caused by a dividend payout, mistaking a cash distribution for an actual loss in value
• Comparing two funds’ NAV directly, instead of comparing their percentage returns over the same period
• Submitting an order after the cutoff time and expecting same-day NAV, then being confused when the next day’s NAV applies instead
• Ignoring the fund category entirely while fixating on NAV, when equity, debt, and hybrid funds behave very differently regardless of their starting NAV

Our explainer on the 50/30/20 budgeting rule is worth reading too, since deciding how much to invest each month matters far more than which NAV you happen to buy in at.

If you’re still building your broader understanding of market basics before diving deeper into NAV mechanics, our guide on what equity actually is is worth reading first, since a lot of NAV confusion stems from not yet having a solid grip on what a fund’s underlying holdings actually represent.

How Should You Actually Evaluate a Mutual Fund Instead of Looking at NAV?

1. Check the fund’s category first (equity, debt, hybrid, index), since this shapes risk and return far more than its current NAV.
2. Compare percentage returns over multiple periods (1-year, 3-year, 5-year) against the fund’s benchmark and category average, not its NAV history.
3. Check the expense ratio, since a lower ongoing cost compounds meaningfully in your favour over a long holding period.
4. Look at the fund’s consistency across market cycles, not just a single strong year that might flatter its NAV trajectory.
5. Decide your investment amount based on your goal, not on how many units a particular NAV lets you buy, since unit count has no bearing on your actual returns.

Our comprehensive stock market guide for beginners covers several of these evaluation basics in more depth if you’re building this research process from scratch. Our piece on building wealth over the long term is worth a read too, since picking the right fund category matters more for that goal than NAV ever will.

HMA Wealth keeps running into this exact NAV confusion with new investors, and it’s one of the simplest misunderstandings to clear up once you see the actual mechanics laid out, which is exactly why we built this explainer the way we did.

This article is educational content meant to help you understand what NAV in mutual funds actually means and how it works, not personalised investment advice. NAV cutoff timings, calculation rules, and fund-specific details can change, so verify current rules directly with your fund house, AMFI, and a SEBI-registered investment adviser before making a specific investment decision.

At the end of the day, understanding what is NAV in mutual funds comes down to one simple reframe: it’s a per-unit price tag, not a performance score. Once that clicks, a falling NAV stops feeling like a red flag and starts looking like exactly what it usually is, a market moving, a dividend paid out, or simply more units quietly landing in your folio at a better price.
