NAV Explained for First-Time Investors — What It Is and What It Isn't
Ask a new mutual fund investor what NAV means, and you'll often get the wrong instinct — the belief that a "lower NAV" fund is somehow cheaper, or offers more value, or has more room to grow than a fund with a higher NAV. This single misunderstanding leads to more poorly reasoned fund selection decisions than almost any other misconception in mutual fund investing. So it's worth getting genuinely clear on what NAV is, and just as importantly, what it isn't.
What NAV Actually Is
Net Asset Value (NAV) is the per-unit value of a mutual fund scheme, calculated as:
NAV = (Total value of the scheme's assets − Total liabilities) ÷ Total number of units outstanding
In practice, this means the AMC values every security in the scheme's portfolio at the end of each business day (using prescribed valuation norms), subtracts any liabilities and accrued expenses, and divides the resulting net value by the number of units currently held by all investors in the scheme. This calculation is done fresh every business day, which is why NAV changes daily.
What NAV Is NOT
NAV is not a stock price, and it does not behave like one. A stock's price reflects market sentiment about the company's future prospects relative to a fixed number of shares — buying more shares of a stock doesn't create new shares out of thin air. A mutual fund, by contrast, is an open-ended pool: when a new investor buys units, the fund simply issues new units at the current NAV and uses that money to buy more of the underlying securities, proportionally. The number of units outstanding constantly expands and contracts with subscriptions and redemptions — it isn't fixed the way a company's share count is (barring corporate actions).
This is precisely why the common belief that "a fund with NAV of ₹10 is cheaper than one with NAV of ₹500, and has more room to grow" is a fundamental misunderstanding. NAV is simply a ratio — assets divided by units outstanding — and the specific number depends entirely on how many units happen to be outstanding, which has no bearing whatsoever on the fund's future return potential.
A Simple Illustration
Imagine two entirely identical funds — same portfolio, same manager, same everything — except Fund A launched with 10 crore units at ₹10 each (raising ₹100 crore), while Fund B launched with 1 crore units at ₹100 each (raising the same ₹100 crore). If both funds' underlying portfolios then grow by 20% over the next year, Fund A's NAV moves to ₹12, and Fund B's NAV moves to ₹120. Both investors experience the identical 20% return. The absolute NAV number tells you nothing about which fund performed better or which is a "better value" — only the percentage change in NAV over time (i.e., the return) matters for comparing performance.
What NAV Actually Tells You
- How much a single unit of the fund is worth today — used to calculate exactly how many units you receive for a given investment amount, or how much you'll receive for units you redeem.
- The fund's historical growth trajectory, when tracked over time — the percentage change in NAV between two dates is exactly what constitutes the fund's return over that period.
- Nothing about valuation or "cheapness" — a high-NAV fund is not overvalued, and a low-NAV fund (such as a newly launched NFO priced at ₹10) is not undervalued or carrying more upside potential; it's simply a fund that either launched more recently, has issued more units relative to its asset base, or has grown its NAV more slowly for entirely explainable reasons.
When NAV Comparisons Are Genuinely Useful
Comparing the NAV level of two different funds is meaningless. But tracking the same fund's own NAV over time is exactly how you measure its actual return — and comparing the percentage change in NAV of two different funds over the same period (rather than their absolute NAV levels) is a legitimate, useful way to compare relative performance.
The NFO Trap
This misconception is precisely what makes New Fund Offers (NFOs), typically launched at a flat ₹10 NAV, superficially appealing to inexperienced investors who mistakenly believe they're "getting in cheap" before the fund "grows." In reality, an NFO's ₹10 starting NAV has no bearing whatsoever on its future performance — a brand-new fund investing in the same universe of stocks as an existing fund with a ₹200 NAV has exactly the same return potential going forward, driven entirely by how its underlying holdings perform, not by where its NAV happens to start.
Why This Matters
Understanding NAV correctly is foundational to avoiding one of the most common — and most easily avoidable — investing mistakes in the Indian mutual fund market. Once you internalise that NAV is simply a per-unit accounting value and not a price signal about cheapness or growth potential, fund selection naturally shifts to where it should be: comparing category, strategy, expense ratio, and historical percentage returns — not the superficially reassuring but ultimately meaningless absolute NAV number.
