Investing NAV mutual fund valuation

Net Asset Value (NAV) of a mutual fund

From WebNotes, a public knowledge base. Last updated 18 May 2026. Reading time ~12 min.

Net Asset Value (NAV) is the per-unit value of a mutual fund scheme, calculated each business day by the Asset Management Company (AMC) as the scheme’s total assets minus liabilities divided by the number of units outstanding at the close of that business day. NAV is the price at which units are issued (subscription) and redeemed, and the daily NAV change captures the scheme’s net investment performance. In the Indian mutual fund framework, NAV computation is regulated by the SEBI (Mutual Funds) Regulations 1996 , with detailed valuation norms published in SEBI circulars and the AMC’s Scheme Information Document (SID).

For a retail investor, NAV is the single most-watched metric of a mutual fund scheme, but it is also the most misunderstood. The widespread retail confusion that “a fund with low NAV is cheaper” is structurally wrong: NAV reflects only the scheme’s per-unit valuation, not its quality, prospects or value-for-money. Two schemes can have identical underlying portfolios at NAV Rs 10 and NAV Rs 1,000 and deliver identical returns from that point onward. This article covers the NAV definition, daily computation, applicable-NAV cut-off rules, common misconceptions, and the relationship between NAV and the investor’s total return.

Definition and formula

The daily NAV of a mutual fund scheme is computed using the formula:

NAV = (Total Assets - Total Liabilities) / Number of units outstanding

Where:

Total Assets is the aggregate market value of the scheme’s investments (equity, debt, cash and other holdings), receivables, and any other assets owned by the scheme.
Total Liabilities is the aggregate of expenses payable, distribution charges, audit fees, custodian charges, trustee fees, and any other obligations of the scheme.
Number of units outstanding is the total number of units issued by the scheme to all unitholders combined, after accounting for any redemptions or fresh subscriptions on that business day.

A scheme starting with a corpus of Rs 100 crore and 10 crore units outstanding would have a starting NAV of Rs 10. If the corpus grows to Rs 200 crore through investment performance and no fresh subscriptions or redemptions occur, NAV would be Rs 20. The growth from Rs 10 to Rs 20 represents a 100 per cent investment return.

Daily NAV computation

Closing-price valuation

For equity holdings, the NAV computation uses the closing market price on the principal stock exchange where the security trades (typically NSE or BSE for Indian listed equities). For debt holdings, the valuation uses the prices published by the SEBI-approved Valuation Agencies , which apply methodology-based mark-to-market pricing rather than relying on thin secondary-market quotes.

Liabilities

The principal liability item is the proportionate daily accrual of the Total Expense Ratio (TER) charged to the scheme. The TER is expressed as an annual percentage, and the daily charge is approximately TER divided by 365. Other smaller liabilities include audit accruals, custodian fees and trustee fees.

Unit-outstanding adjustments

The unit count for the NAV denominator is adjusted for the business day’s net subscription and redemption transactions. SEBI’s applicable-NAV rules govern which day’s NAV applies to a given investor’s transaction.

Publication timing

AMCs are required to publish daily NAVs on their official websites by 11.00 pm of the same business day (or the next business day for funds with overseas exposure that need NYSE closing prices). NAVs are also published on the AMFI website and the principal financial-news websites.

Applicable NAV rules

A material practical question for investors is: when I place a subscription or redemption order today, which day’s NAV applies? SEBI’s cut-off-time rules for applicable NAV are:

Equity-oriented schemes (cut-off 3.00 pm)

Subscription before 3.00 pm: same-day NAV applies, subject to the funds being received in the AMC’s collection account before the cut-off.
Subscription after 3.00 pm: next business day’s NAV applies.
Redemption before 3.00 pm: same-day NAV applies.
Redemption after 3.00 pm: next business day’s NAV applies.

Liquid and overnight schemes (cut-off 1.30 pm)

Subscription before 1.30 pm: same-day NAV applies (this includes the prior-day’s closing NAV due to T+0 cycle).
Subscription after 1.30 pm: next business day’s NAV applies.

Debt schemes other than liquid (cut-off 3.00 pm)

Same rules as equity-oriented schemes.

The applicable-NAV rule changed materially in February 2021 when SEBI required actual fund realisation (not just receipt of instruction) before the cut-off for the same-day NAV. This shifted some practical implications for large investments routed through banks: a same-day NAV is no longer guaranteed merely by placing the order before 3 pm if bank settlement delays the fund credit.

For the granular per-platform mechanics, see applicable NAV cut-off rule .

NAV at scheme inception (NFO)

When a mutual fund scheme is launched through a New Fund Offer (NFO) , the initial NAV is set at Rs 10. The Rs 10 starting NAV is purely a notional starting point: it has no relationship to the scheme’s expected returns, the strength of the AMC, or the quality of the underlying portfolio. Investors should not perceive a Rs 10 NAV as “low” or “cheap”; it is merely the chosen denomination at scheme launch.

This is the source of the most common retail NAV misconception (covered below). The Rs 10 starting NAV applies industry-wide as the conventional default. Some schemes have been launched at higher starting NAVs (Rs 100 or Rs 1,000) but this is rare in the Indian context.

NAV and investor returns

NAV change measures investment performance

The investor’s return on a mutual fund investment over a holding period is measured by the change in NAV from purchase to redemption (adjusted for any dividends or IDCW distributions received during the period). The NAV change in isolation does not measure total return if dividend or IDCW payouts have occurred between purchase and redemption.

For growth-option schemes (which do not pay out dividends), the NAV change equals the total return. For IDCW-option schemes, the NAV change captures only the price appreciation; the dividend payouts add to the total return separately.

NAV cannot fall below zero

In practice, NAV cannot fall below zero (since a scheme’s assets cannot be negative). Theoretically NAV approaching zero would indicate severe losses on the underlying portfolio, but Indian mutual funds operating under SEBI’s investment restrictions and risk-management framework have not historically experienced NAV declines beyond ~30-40 per cent in worst-case equity-market drawdowns.

NAV and SIP purchase points

For a Systematic Investment Plan (SIP) investor, the periodic purchase is made at the applicable NAV on each SIP date. Over a long SIP, the investor accumulates units at varying NAV levels, achieving rupee-cost averaging. The eventual NAV at redemption determines the realised value, but the average purchase NAV determines the effective cost basis.

Common retail misconceptions

“Low NAV is better”

The single most-common retail mistake is to treat a low NAV as indicative of a cheaper or better fund. This is structurally wrong:

A scheme launched 10 years ago with strong performance might have NAV Rs 500.
A scheme launched yesterday in an NFO has NAV Rs 10.
Both schemes, if they have identical underlying portfolios going forward, will deliver identical returns from this point onward.

The investor putting Rs 10,000 into the Rs 500-NAV scheme gets 20 units; the investor putting Rs 10,000 into the Rs 10-NAV scheme gets 1,000 units. Both end up with Rs 10,000 worth of exposure to the same portfolio. The “fewer units” is not worse; it is merely a different denomination.

This misconception is particularly exploited around NFO launches, when AMCs sometimes market the “Rs 10 NAV” as an attractive entry point. SEBI’s advertisement code for mutual funds prohibits AMCs from suggesting that a low NAV is itself an advantage, but the marketing tone often gets close to this implication.

“NAV growth is the return”

NAV growth equals total return only for growth-option schemes. For IDCW-option schemes, NAV growth understates total return because some of the return has been paid out as dividends. Investors comparing two schemes should ensure they are comparing the same option type (typically growth versus growth).

“Higher NAV means scheme is overvalued”

A scheme’s NAV reflects its historical performance, not its current valuation. A Rs 500-NAV scheme is not “expensive” in the same sense that a Rs 500-priced stock might be expensive. The Rs 500 NAV simply means each unit represents Rs 500 of underlying assets; new investors are not “paying a premium” since they are buying the same underlying assets per rupee invested.

“NAV is the price I would get if I redeem”

NAV is the price for both subscription and redemption (with applicable cut-off rules), but the actual realised value depends on any exit load charged on the redemption. A scheme charging 1 per cent exit load on redemption within the first year would deliver NAV minus 1 per cent on a year-one redemption.

NAV in different scheme types

Growth-option schemes

The growth-option NAV captures total return reinvested into the scheme. A Rs 10 starting NAV that grows to Rs 50 over 10 years represents 5x total return (compound annual growth rate approximately 17 per cent per year).

IDCW (Income Distribution cum Capital Withdrawal) schemes

The IDCW-option NAV reflects only the post-distribution residual value. The total return for an IDCW-option investor is the sum of NAV growth plus the cumulative IDCW distributions received during the holding period. After SEBI’s 2021 rebranding of the dividend option to IDCW , the disclosure makes the structure clearer: IDCW distributions are essentially withdrawals from the corpus, not separate dividend income.

Bonus and split schemes (historical)

In the pre-2018 Indian mutual fund regime, AMCs occasionally issued bonus units or executed unit splits, which mechanically reduced NAV without changing the investor’s total holding value. These practices have effectively been discontinued post the SEBI scheme categorisation reform.

NAV publication and transparency

Daily NAV publication

AMCs publish daily NAVs on their official websites by 11.00 pm of the same business day. The NAV is also published on:

AMFI industry data pages.
BSE StAR MF and NSE NMF II platforms.
The principal financial-news websites (MoneyControl, Value Research, Economic Times).
Direct-plan platforms including Zerodha Coin , Groww , Kuvera , ET Money .

Historical NAV access

For tax-computation purposes (calculating capital gains on redemption), investors need historical NAVs. AMC websites typically publish daily historical NAVs going back several years. AMFI’s website carries the consolidated historical NAV data across all AMCs and schemes.
