Does a Lower NAV Mean a Mutual Fund Is Cheaper?
Does a lower NAV mean a mutual fund is cheaper? No. See the exact maths, why ₹10 NFOs are not bargains, and what to compare instead: cost, valuation, record.
In this article
No. A lower NAV does not make a mutual fund cheaper or more likely to give higher returns. NAV is simply the value of one unit; a lower NAV gives you more units, a higher NAV gives you fewer, and the same percentage move in the portfolio produces the same rupee gain either way. What actually makes a fund "cheap" or "expensive" is its expense ratio and the valuation of the stocks or bonds it holds.
What NAV really is
Net asset value per unit is calculated every business day:
NAV = (market value of all holdings + cash − liabilities and expenses) ÷ number of units outstanding
A fund launched in 2005 at ₹10 that has grown fifteenfold has a NAV of ₹150. A fund launched last month is still close to ₹10. Neither number tells you whether its holdings are good value. It mostly tells you how old the fund is and how much it has grown since launch.
Shares are different: a share's price reflects the market's view of one company's value, and comparing price with earnings (P/E) tells you something. A fund's NAV is just the arithmetic of a portfolio divided by units.
Worked example: same portfolio, different NAV (illustrative)
Two funds hold exactly the same portfolio. Fund A's NAV is ₹20 and Fund B's is ₹200. You invest ₹1,00,000 in each.
Mutual fund purchases attract stamp duty of 0.005%, so ₹5 is deducted and ₹99,995 is invested in each.
| Fund A | Fund B | |
|---|---|---|
| NAV at purchase | ₹20 | ₹200 |
| Units bought | 99,995 ÷ 20 = 4,999.750 | 99,995 ÷ 200 = 499.975 |
| Portfolio rises 12% (illustrative) | NAV ₹22.40 | NAV ₹224.00 |
| Value | 4,999.750 × 22.40 = ₹1,11,994.40 | 499.975 × 224 = ₹1,11,994.40 |
| Gain | ₹11,994.40 | ₹11,994.40 |
Ten times the units, identical result. The 12% is an illustrative figure, not a forecast. You can run any amount and assumed return through the lumpsum calculator; the NAV never enters the calculation, only the rate of return does.
The ₹10 NFO myth
New fund offers (NFOs) are usually priced at ₹10 per unit, and they are often marketed as an "opportunity to get in at ₹10". That price is a convention, not a discount.
When the NFO money is invested, the fund buys shares at today's market prices, the same prices an existing fund with a NAV of ₹300 pays. If the market then rises 10%, both funds' NAVs rise about 10%: from ₹10 to ₹11, and from ₹300 to ₹330.
What an NFO lacks is a track record. You cannot see how the manager handled a bad market, how closely an index fund tracked its benchmark, or how the portfolio actually looks once fully invested. SEBI rules require fund houses to deploy NFO money within a set period, generally 30 business days, so the initial portfolio is not known in advance. That does not make NFOs bad, but it means they need a reason beyond "low NAV", such as a genuinely new strategy or index you cannot get elsewhere.
Why NAVs differ within the same scheme
One scheme can show several NAVs. None is cheaper in a useful sense.
| Variant | Why the NAV is different | What it means for you |
|---|---|---|
| Direct vs regular plan | Direct plan has a lower expense ratio, so its NAV grows faster | Higher direct NAV = lower costs; see direct vs regular mutual funds |
| Growth vs IDCW option | IDCW option pays out part of the value, so its NAV stays lower | Lower IDCW NAV reflects money already paid out |
| Older vs newer scheme | Older fund has compounded for longer | Says nothing about future returns |
What an IDCW payout does to NAV (illustrative)
You hold 1,000 units of an IDCW option at a NAV of ₹15, worth ₹15,000. The fund declares IDCW of ₹1 per unit.
- Cash paid to you: 1,000 × ₹1 = ₹1,000
- NAV after the payout (ignoring market moves): ₹15 − ₹1 = ₹14
- Value of units: 1,000 × ₹14 = ₹14,000
- Total: ₹14,000 + ₹1,000 = ₹15,000, unchanged
The payout is not extra money; it is your own money moved from the fund to your bank account. As of October 2026, it is taxed at your slab rate, and the fund house may deduct TDS once payouts from that fund exceed ₹10,000 in the financial year (Section 393 of the Income-tax Act, 2025, which replaced old Section 194K). In the growth option, the same value stays invested and is taxed only when you redeem, at capital gains rates.
What "expensive" and "cheap" actually mean for a fund
1. Cost: the expense ratio
The total expense ratio (TER) is deducted from the fund every day. A fund with a TER of 1.5% costs three times as much as one with 0.5%, whatever their NAVs. This is the cost you can control.
2. Valuation of the holdings
A fund's factsheet usually shows portfolio-level ratios such as price-to-earnings (P/E) and price-to-book (P/B). A portfolio at 40 times earnings is more expensively valued than one at 20 times. That can still be justified by faster growth, but it is a real valuation signal; NAV is not. Our guide on how to read financial statements explains these ratios.
3. Performance against the right benchmark
Compare a fund's rolling 5- and 10-year returns with its benchmark index and category, using annualised measures. CAGR vs XIRR vs absolute return explains which number to use.
A practical checklist instead of NAV
| Check | Where to find it | Why it matters |
|---|---|---|
| Category and mandate | Scheme information document | Tells you what the fund can own |
| Expense ratio (direct plan) | AMC website, AMFI | Directly reduces your return |
| Returns vs benchmark, 5+ years | Factsheet, AMFI | Shows whether the manager added value |
| Risk-o-meter level | Factsheet | SEBI's six-level risk label, Low to Very High |
| Portfolio P/E, top holdings | Factsheet, monthly portfolio | Valuation and concentration |
| Overlap with your other funds | Monthly portfolios | Avoids buying the same stocks twice; see portfolio overlap |
| Exit load | Scheme information document | Cost of leaving early |
Where price per unit does matter a little
- ETFs trade on the exchange, and their market price can drift above or below the indicative NAV. Paying a premium to NAV is a real cost. See what is an ETF.
- Minimum investments are set in rupees, not units, so a high NAV never locks you out of a mutual fund.
- Fractional units are allotted to three decimal places, so a ₹500 SIP buys about 1.667 units of a ₹300 NAV fund without any rounding loss worth worrying about.
Key takeaways
- A lower NAV gives more units, not better value; returns depend on the percentage change in NAV.
- In the illustration, ₹1,00,000 in a ₹20 NAV fund and a ₹200 NAV fund both became ₹1,11,994.40 after a 12% rise.
- NFOs at ₹10 buy stocks at the same market prices as older funds; the ₹10 reflects age, not cheapness.
- A higher direct-plan NAV signals lower costs; a lower IDCW NAV reflects money already paid out.
- Judge funds by expense ratio, portfolio valuation, benchmark-relative returns, risk level and fit with your portfolio.
Frequently asked questions
Is it better to buy a mutual fund with a low NAV?
No. A low NAV only means you get more units for the same money. Your gain depends on the percentage change in NAV, which depends on how the underlying portfolio performs, not on the starting NAV.
Is an NFO at Rs 10 cheaper than an existing fund?
No. An NFO starts at Rs 10 by convention, but it buys the same stocks at the same market prices as existing funds. A Rs 10 NAV says nothing about value; it only says the fund is new.
Why does a direct plan have a higher NAV than a regular plan?
Both plans hold the same portfolio, but the direct plan deducts a lower expense ratio every day, so its NAV grows slightly faster over time. The higher NAV reflects lower costs, which is good for the investor.
What should I compare instead of NAV?
Compare the expense ratio, the fund's returns against its benchmark over 5 years or more, its risk-o-meter level, portfolio valuation such as price-to-earnings, and how well it fits your goal and other holdings.
Does NAV fall after an IDCW payout?
Yes. When a fund pays IDCW, the NAV drops by roughly the amount paid per unit, because the money leaves the fund. Your total value is unchanged at that moment, but the payout is taxable at your slab rate.
