If you have ever looked at your mutual fund investment and wondered why the NAV keeps changing, why a lower NAV does not necessarily mean a better deal, or why your investment value does not seem to move in proportion to what you expected — you are experiencing the NAV confusion that puzzles millions of new mutual fund investors in India. NAV is simultaneously one of the simplest and most misunderstood concepts in personal finance. This guide explains everything clearly so that NAV never confuses you again.
What is NAV?
NAV stands for Net Asset Value — the per-unit price of a mutual fund scheme at any given point in time. Think of a mutual fund as a large cooking pot into which thousands of investors pour their money. The fund manager uses this pooled money to buy a portfolio of stocks, bonds, or other securities. The total current market value of everything in that pot, minus any liabilities the fund owes, divided by the total number of units that have been issued to all investors — that final number is the NAV.
Mathematically: NAV = (Total Assets of the Fund − Total Liabilities) ÷ Total Number of Units Outstanding
For example, if a fund has assets worth ₹500 crore, liabilities of ₹5 crore, and 10 crore units outstanding, the NAV is (500 − 5) ÷ 10 = ₹49.50 per unit.
Why Does NAV Change Every Day?
NAV changes every business day because the market value of the underlying securities in the fund’s portfolio changes every day. If the stocks in an equity fund rise in price on a given day, the total asset value of the fund increases, and the NAV per unit increases proportionally. If the stocks fall, the NAV falls. For debt funds, NAV changes with changes in bond prices and interest accruals. For liquid funds, NAV changes are smaller and more predictable because the underlying instruments are short-term, low-volatility money market instruments.
NAV is calculated and published once per business day after the market closes — typically by 9–10 PM for equity funds and by 11 PM for liquid funds. SEBI mandates that all AMCs publish daily NAV on their websites and on AMFI’s official portal. The NAV at which your transaction is processed depends on whether your redemption or purchase request is received before or after the cut-off time — typically 3 PM for equity and hybrid funds and 1:30 PM for liquid and overnight funds.
The Biggest NAV Misconception — Higher NAV Does Not Mean Expensive
The most widespread and most damaging misconception about NAV is that a fund with a low NAV (say ₹15) is cheaper and therefore a better buy than a fund with a high NAV (say ₹150). This is completely incorrect and the misunderstanding stems from confusing NAV with a stock price.
When you buy shares of a company, the share price reflects market sentiment about that specific company’s value — a lower price may genuinely represent better value in some cases. But NAV does not work this way. A fund with NAV of ₹15 and a fund with NAV of ₹150 give you absolutely identical returns for the same underlying portfolio performance. If the portfolio grows by 10%, the ₹15 NAV fund’s NAV becomes ₹16.50 and the ₹150 NAV fund’s NAV becomes ₹165 — you gain exactly 10% in both cases. The only difference is how many units you receive, not how much wealth you accumulate.
A high NAV simply means the fund has been around longer and has grown — it is a sign of the fund’s track record, not its expensiveness. A fund with NAV of ₹500 that was launched 15 years ago has delivered consistent growth over 15 years. A newly launched fund with NAV of ₹10 (the standard launch NAV) has no performance history to evaluate. For this reason, choosing a fund based on low NAV is one of the most common and most harmful investment mistakes beginners make.
How Many Units Do You Get for Your Investment?
When you invest in a mutual fund, you are allocated units based on the applicable NAV. Units Received = Investment Amount ÷ NAV. If you invest ₹10,000 in a fund with NAV of ₹50, you receive 200 units. If the same ₹10,000 is invested in a fund with NAV of ₹500, you receive 20 units. Your total investment is identical in both cases, and if both funds grow by 10%, your wealth increases by ₹1,000 regardless of whether you hold 200 units or 20 units.
Cut-Off Timing and Which NAV You Get
SEBI has specific rules about which day’s NAV applies to your transaction, and understanding this prevents surprises. For equity, hybrid, and ELSS funds, if your purchase request and funds reach the AMC before 3 PM on a working day, you receive that day’s NAV. Requests received after 3 PM receive the next working day’s NAV. For liquid and overnight funds, different cut-off rules apply — typically 1:30 PM for same-day NAV. For redemptions, similar logic applies — requests before cut-off get the same day’s NAV, requests after get the next day’s NAV.
This cut-off timing matters for large investments where a single day’s NAV movement could represent meaningful amounts. For regular SIPs and smaller investments, the timing difference has negligible practical impact.
NAV and Dividend Payouts — Why NAV Falls on Ex-Dividend Date
If you hold a mutual fund scheme with the dividend option and the fund declares a dividend, you will observe the NAV falling by exactly the dividend amount per unit on the ex-dividend date. This surprises many investors who think the fund’s value has declined. In reality, the fund has simply distributed a portion of its accumulated gains to unitholders — the total wealth (NAV value in your holding plus the dividend received) remains the same before and after the dividend. The NAV fall on dividend declaration is mathematically inevitable and not a loss.
Frequently Asked Questions
Q: I bought units at NAV of ₹45. The NAV is now ₹40. Have I lost money permanently?
A: You have a current unrealised loss, but it is not permanent. NAV reflects the current market value of the portfolio. If the underlying portfolio recovers, your NAV will recover too. Assess whether the fund’s investment strategy remains sound rather than reacting to temporary NAV movements.
Q: Should I wait for the NAV to fall before investing?
A: For long-term investments and SIPs, timing the NAV entry point has minimal impact on final returns. Attempting to time NAV entry typically results in missed investment opportunities.
Q: Why do different funds in the same category have very different NAVs?
A: NAV differs based on the fund’s age and historical performance — an older fund with consistently strong performance will have a higher NAV than a newer fund in the same category. NAV alone tells you nothing about future performance potential.
