NAV in Mutual Funds: What It Measures and What It Does Not

By Vinoth Kanna Published 18 August 2026 10 min read Guides · Mutual Funds

A new mutual fund investor comparing two schemes usually notices the NAV first. One fund quotes ₹12 a unit, another ₹480, and the ₹12 fund looks like the bargain: the same money buys forty times as many units. The instinct comes from shopping, where a lower price for the same item is a better deal. In mutual funds the instinct is wrong, and acting on it changes nothing except how many units appear in your statement.

This guide explains what NAV in mutual funds actually measures, how the number is calculated every business day, how cut-off times decide which day’s NAV you receive, and why comparing NAVs across two different funds tells you nothing about which is cheaper or better. It belongs to Gale’s mutual fund hub, which stays deliberately on fund data and mechanics.

What is NAV in mutual funds?

Net asset value in mutual funds is the per-unit worth of everything a scheme owns, after everything it owes:

NAV = (market value of the scheme’s assets − liabilities and accrued expenses) ÷ units outstanding

A mutual fund pools money from many investors and buys a portfolio of shares, bonds or other assets; investors hold units of that pool rather than the underlying securities directly. (The what is a mutual fund guide walks through that structure from the beginning.) NAV is simply the pool’s value cut into per-unit slices. If a scheme’s portfolio is worth ₹500 crore after liabilities and 25 crore units exist, the NAV is ₹20 — an illustration, but the arithmetic is exactly this.

That is the whole mutual funds NAV meaning: a valuation of one unit on one day. It is where the resemblance to a share price ends. A share price is negotiated all day between buyers and sellers on an exchange and can drift far from any calculation of underlying value. NAV is not negotiated at all. The fund house computes it from closing market prices under SEBI’s valuation norms, and every investor transacting that day gets the same number. There is no bid, no ask and no bargaining.

The “low NAV is cheap” myth, worked through

Here is the myth in its natural habitat: a distributor points at a new fund offer priced at ₹10 and says it is cheaper than an established fund at ₹500. The example below shows why the pitch is empty. The two funds, their NAVs and the 12% move are illustrations, not real schemes or expected returns.

Assume both funds hold essentially the same portfolio, and that portfolio gains 12% over some period.

	Fund A (illustration)	Fund B (illustration)
NAV on purchase date	₹10	₹500
Amount invested	₹1,00,000	₹1,00,000
Units allotted	10,000	200
Portfolio move	+12%	+12%
NAV after the move	₹11.20	₹560
Value of holding	₹1,12,000	₹1,12,000

Identical outcome, to the rupee. Fund A’s investor holds fifty times more units, and each unit is worth one-fiftieth as much. What you own in a mutual fund is a proportional slice of the portfolio, and the size of that slice is set by the rupees you invested — not by the unit count. Units are a bookkeeping denomination, the way a ₹2,000 holding is the same wealth whether it is counted as twenty ₹100 notes or four ₹500 notes.

The myth also fails in reverse: a high NAV does not mean a fund has “peaked” or has less room to grow. NAV per unit can rise without limit because it tracks the portfolio, and a portfolio’s growth does not care how many slices it has been cut into.

Why one fund quotes ₹10 and another ₹500

If NAV says nothing about cheapness, what does it reflect? Mostly history and plumbing:

Age. Every scheme starts near ₹10 at launch. A fund quoting ₹500 has typically existed long enough for its portfolio to multiply many times since inception. A ₹10–₹15 NAV usually marks a young scheme, not an undervalued one.
Payout history. Under the IDCW option, distributions are paid out of the scheme’s own assets, and NAV drops when they are paid. Two options of the same scheme show different NAVs for this reason alone.
Plan type. The direct plan of a scheme shows a higher NAV than the regular plan of the very same scheme, because the regular plan accrues distribution commission daily. Same portfolio, same manager, two NAVs — the direct vs regular guide quantifies what that gap compounds into.

None of these is a quality signal. A scheme’s NAV level tells you roughly when it launched and what it has paid out — nothing about what its portfolio will do next.

How daily NAV is computed

A mutual fund NAV is declared once per business day, after markets close. The sequence, simplified:

Value the portfolio. Each holding is marked at its closing or fair-valuation price under SEBI’s valuation norms — equities at exchange closing prices, debt at prescribed valuation methods.
Add what is owed to the scheme. Accrued interest, dividends declared but not yet received, and receivables.
Subtract liabilities and accrued expenses. This includes the day’s slice of the expense ratio — management fee and other scheme costs accrue daily inside the NAV, which is why costs compound quietly. The expense ratio and exit load guide covers how that daily deduction works and what leaves your money at exit.
Divide by units outstanding. The result is that day’s NAV, published on the AMC’s website and on AMFI’s portal, typically the same evening (with later timelines for some fund categories, such as overseas funds).

Because the calculation happens once daily, there is no intraday NAV to watch. A mutual fund’s value does not tick through the session the way a share does; the portfolio moves all day, but the unit price is struck once, at the close.

Exchange-traded funds are the partial exception. An ETF has a daily NAV like any scheme, but its units also trade on the exchange at a market price that can sit slightly above or below NAV depending on demand and liquidity. Buying an ETF needs the demat and trading setup described in the how to start investing guide; buying a regular mutual fund does not.

Cut-off times: which day’s NAV you get

Since NAV exists only once a day, the practical question is which day’s NAV applies to your order. That is governed by cut-off times, and at a high level the current framework works like this:

For equity and most other non-liquid schemes, a purchase gets the same day’s NAV only if the application is valid and the money is actually realised by the fund before the 3:00 p.m. cut-off. Otherwise the next business day’s NAV applies.
Liquid and overnight funds follow different, earlier cut-off rules with their own NAV conventions.
Redemptions follow the cut-off based on when the valid request is submitted.

The funds-realisation condition matters more than most investors expect: with some payment modes, money can take time to reach the scheme, so an order placed at 2:45 p.m. may still receive the next day’s NAV. Rules on cut-offs have changed before and can change again, so treat this as the shape of the system and confirm the current timings with SEBI, AMFI or the fund house before relying on them.

Two consequences follow. First, you cannot time an intraday dip in a mutual fund — there is no intraday price to catch, only the close. Second, when markets move sharply after the cut-off, your order prices at a NAV that already includes that move. Neither is a flaw; both are simply how a once-daily valued pool must work.

Why NAV comparisons across funds are meaningless

Put the pieces together and the cross-fund comparison collapses:

Two funds launched in different years will show different NAVs even with identical portfolios and identical returns since your purchase date.
Two options of one scheme (growth vs IDCW) show different NAVs because of payouts.
Two plans of one scheme (direct vs regular) show different NAVs because of costs.

If NAV cannot even be compared across two variants of the same scheme, it certainly cannot rank two different schemes. What NAV levels mostly encode is launch dates.

The comparison that does work is percentage change over identical periods, and the portfolio and costs behind it. Nifty 50 index funds make the point cleanly: several schemes hold virtually the same fifty companies in the same weights, yet quote NAVs anywhere from the tens to the hundreds depending on when each launched. Ranking them by NAV is astrology; ranking them by expense ratio and tracking difference is analysis — and that is exactly what Gale’s Nifty 50 index fund comparison lines up, scheme by scheme.

Question	Can NAV answer it?	What answers it instead
Is this fund cheaper than that one?	No	Expense ratio, exit load
Has this fund performed better?	No	Returns over identical periods
Is this fund about to grow faster because its NAV is low?	No	Nothing — NAV level has no predictive content
How many units will my money buy?	Yes	Amount ÷ applicable NAV
What is my holding worth today?	Yes	Units × today’s NAV
Is this ETF trading rich or cheap to its portfolio?	Partly	Market price vs NAV (premium or discount)

Where NAV genuinely matters

Dismissing the myth does not make NAV useless. It has four honest jobs:

Allotment arithmetic. Your units equal the amount invested divided by the applicable NAV. Every statement builds on this line.
Your own return calculation. Units × current NAV against what you paid, or a proper annualised calculation when there are multiple dates, is how you measure your actual outcome — not the scheme’s advertised point-to-point return.
Reading sudden drops. A NAV that falls sharply on one day, in a scheme with an IDCW option, is usually a payout, not a crash. Check the distribution record before reacting.
ETF and index-fund monitoring. NAV is the reference for an ETF’s premium or discount, and the base series from which an index fund’s tracking difference is measured.

FAQ

What is NAV in mutual funds in one line?

NAV is the per-unit value of a scheme’s portfolio after liabilities and accrued expenses — the fund’s assets minus what it owes, divided by units outstanding, computed once per business day.

Is a fund with a lower NAV cheaper?

No. NAV level mostly reflects how long a scheme has existed and what it has paid out. Equal rupee investments in a ₹10 fund and a ₹500 fund holding the same portfolio grow to the same value, as the worked illustration above shows.

Why did my fund’s NAV fall when markets were flat?

The common benign cause is an IDCW payout, which is paid from the scheme’s assets and reduces NAV on the payout date. Compare the drop with the scheme’s distribution announcement before assuming portfolio losses.

No. A share price is set continuously by buyers and sellers and can trade far from underlying value. NAV is a once-daily calculation from closing prices; every investor transacting that day gets the same NAV, with no bid-ask spread.

When is NAV declared?

After market close on each business day, typically the same evening on the AMC and AMFI websites; certain categories, such as funds investing overseas, publish on a later timeline.

What to weigh

NAV is the measuring stick, not the merchandise. It tells you what one unit of a specific pool is worth today, and it does that job precisely; it tells you nothing about whether that pool is worth buying. The numbers worth weighing sit behind the NAV: what the portfolio holds, what the scheme charges every day, and — for index funds — how faithfully the NAV series tracks its benchmark. A decision built on those three survives contact with reality. A decision built on “₹12 is cheaper than ₹480” was never a decision at all; it was a misreading of the label.
