What is NAV in Mutual Funds? Complete Guide for Indian Investors

If you have ever browsed mutual funds, you have seen the term NAV. New investors often assume that a fund with NAV ₹15 is "cheaper" and therefore a better buy than a fund with NAV ₹1,500. This is one of the most common — and costly — misconceptions in mutual fund investing. Here is everything you need to know about NAV.

What is NAV?

NAV stands for Net Asset Value. It is the per-unit price of a mutual fund scheme on a given day. Think of it as the price at which you buy or sell one unit of the fund.

Formula:

NAV = (Total Assets of the Fund – Liabilities) ÷ Total Number of Units

For example, if a fund has total assets of ₹1,000 crore, liabilities of ₹10 crore, and 5 crore units outstanding:

NAV = (₹1,000 crore – ₹10 crore) ÷ 5 crore = ₹198 per unit

How NAV Changes Daily

The NAV of an equity mutual fund changes every business day after market close (typically declared by 11 PM). It changes because the market value of the fund's stock portfolio changes every day.

• Markets go up → fund's stock portfolio is worth more → NAV increases
• Markets go down → fund's stock portfolio is worth less → NAV decreases
• Fund receives dividends from stocks → increases total assets → NAV increases slightly
• Fund pays out IDCW (dividend) → reduces total assets → NAV drops by the dividend amount

The Biggest NAV Myth: Low NAV = Cheap Fund

This is the most dangerous misconception about mutual funds. Many investors prefer funds with a NAV of ₹10 or ₹15 over funds with NAV of ₹1,000 or ₹2,000, thinking they are getting a "cheaper" deal or more units for the same money.

This thinking is completely wrong. Here's why:

Imagine two funds both invested in identical portfolios (same stocks, same weights):

• Fund A: NAV ₹10 (launched recently)
• Fund B: NAV ₹1,000 (launched 15 years ago, same portfolio)

You invest ₹10,000 in each:

• Fund A: 1,000 units at ₹10
• Fund B: 10 units at ₹1,000

Now markets go up 10%:

• Fund A NAV: ₹11 → Your ₹10,000 is now ₹11,000 (1,000 × ₹11)
• Fund B NAV: ₹1,100 → Your ₹10,000 is now ₹11,000 (10 × ₹1,100)

Identical return. The number of units or the NAV level doesn't matter — only the percentage change matters. A high NAV simply means the fund has been running longer and has compounded its returns, which is actually a good sign, not a bad one.

What a High NAV Actually Means

A high NAV means the fund has been generating returns for a long time. A fund launched in 2005 with NAV ₹10 that now has NAV ₹3,000 has grown 300x over 20 years — that's exceptional performance, not a reason to avoid it.

Conversely, a new fund offering (NFO) that starts at NAV ₹10 is NOT cheaper. It simply has no track record, which is actually a disadvantage — you cannot evaluate its performance.

NAV and SIP — What Matters

When you invest via SIP, you buy units at the NAV on the day your SIP is processed. What matters is not whether NAV is high or low in absolute terms, but whether it rises over your investment horizon.

NAV on your SIP date determines how many units you receive:

• SIP of ₹5,000 when NAV = ₹100 → 50 units allotted
• SIP of ₹5,000 when NAV = ₹80 (market dip) → 62.5 units allotted

This is why SIPs during market dips actually benefit you — you accumulate more units at lower NAV, boosting your returns when markets recover.

NAV vs Returns — What to Track

Don't track NAV. Track returns — specifically 1Y, 3Y, and 5Y CAGR (Compound Annual Growth Rate). CAGR tells you how much the fund's NAV has grown on an annualised basis.

A fund with NAV ₹1,500 delivering 14% 5Y CAGR is far better than a fund with NAV ₹20 delivering 8% 5Y CAGR — despite the much lower absolute NAV of the second fund.

Conclusion

NAV is simply the per-unit price of a mutual fund. Higher NAV does not mean expensive — it means the fund has performed well over time. Lower NAV does not mean cheap or good value. When evaluating mutual funds, focus entirely on consistent returns over 3–5 years, expense ratio, star rating, and fund house reputation — never on the absolute NAV level.
