What is NAV in a Mutual Fund?
NAV in a mutual fund is the per-unit value of the fund, calculated daily as net assets divided by units outstanding. It tracks how the fund's holdings change in value, but it is not a measure of how cheap or expensive a fund is.
NAV in a mutual fund is the per-unit value of the fund, calculated by dividing the total value of all the fund's holdings, minus expenses, by the number of units in circulation. If you understand what is a mutual fund, NAV is just the price tag attached to one share of that pooled investment, recalculated at the end of every trading day.
Most new investors hear the word NAV and start treating it like a stock price. That is a costly mistake. NAV behaves very differently from share price, and confusing the two leads to bad buy decisions.
The simple formula behind NAV
NAV stands for Net Asset Value. The math is short.
NAV equals the market value of all securities the fund holds, plus cash and receivables, minus liabilities and expenses, divided by the number of fund units outstanding.
Suppose a mutual fund holds shares worth 100 crore rupees, has 1 crore rupees in cash, owes 1 crore rupees in expenses, and has issued 10 crore units. The NAV per unit is (100 plus 1 minus 1) divided by 10, which equals 10 rupees per unit.
The fund repeats this calculation once at the end of every trading day, after the market closes. That is why every transaction you place during the day actually settles at the next computed NAV, not at the price you saw when you clicked buy.
How NAV moves day to day
NAV moves up when the underlying holdings rise in value or when the fund earns dividends and interest. NAV moves down when holdings fall, when the fund pays out distributions, and after expense fees are deducted daily.
Two clean takeaways
- NAV reflects what each unit is worth, not what it should be worth.
- NAV always lags the live market by a few hours because the calculation happens after market close.
Why NAV is not a stock price
This is where many beginners trip. A low NAV does not mean a fund is cheap. A high NAV does not mean a fund is expensive.
The math proves it
Imagine two equity mutual funds with identical portfolios. Fund A launched five years ago at 10 rupees per unit and now trades at 30 rupees. Fund B launched yesterday at 10 rupees. They hold the same stocks. If those stocks rise 10 percent tomorrow, both funds rise 10 percent. Fund A goes to 33. Fund B goes to 11. The 30-rupee fund did not become less profitable just because its NAV is higher.
What this means for new investors
Choosing a fund based on a low NAV is like choosing a restaurant because its menu lists prices in cents. The number is just a unit of accounting. Performance, fees, fund manager skill, and risk profile matter. NAV does not.
How NAV interacts with your buy and sell timing
Mutual funds use a cut-off time, not a live price. Knowing the cut-off helps you avoid surprise prices.
The 3 PM rule
For most equity and debt funds in India, orders received and money credited before 3 PM on a working day get the same day's NAV. Orders after 3 PM get the next working day's NAV. Liquid funds have a different cut-off near 1:30 PM.
What this means
If markets are tanking and you place a redemption at 4 PM, you will not lock in today's closing NAV. You will receive tomorrow's, which could be lower. Likewise, when markets surge late in the afternoon, an order placed before 3 PM captures today's lower NAV before the rally is fully priced in.
FAQs
Q: Why does NAV update only once a day?
Mutual funds compute NAV after the underlying market closes so that the fund knows the final price of every holding for the day. ETFs trade live throughout the day, but their NAV is still computed once daily.
Q: Does NAV include the expense ratio?
Yes. Daily expenses, including the fund's expense ratio, are deducted before the NAV is published, so the published NAV is already net of fees.
Real-world example
You invest 50,000 rupees in an equity mutual fund whose NAV is 100 rupees. You receive 500 units. Two years later, the NAV has grown to 130 rupees. Your 500 units are now worth 65,000 rupees, a gain of 30 percent.
If during this period the fund declared a 5 rupee dividend per unit, the NAV would have dropped to 125 rupees on the day of payout. You would have received 2,500 rupees in cash, but your remaining units would be worth slightly less. Your total return would still be the same, just split between cash distribution and unit value.
Common mistakes investors make with NAV
- Picking funds by lowest NAV. The number tells you nothing about quality.
- Treating NAV moves like stock prices. A 1 percent drop in NAV is normal in equity funds. Do not panic.
- Ignoring NAV cut-off times. Late-day orders get the next day's price, which can swing the actual buy or sell rate.
- Comparing NAVs across categories. A debt fund NAV cannot be compared to an equity fund NAV. Different return profiles, different risks.
How to use NAV correctly
| Use NAV for | Do not use NAV for |
|---|---|
| Tracking your fund's daily progress | Comparing fund cheapness |
| Calculating gains on units sold | Predicting future return |
| Confirming buy and sell prices | Choosing between funds |

No. NAV is just an accounting unit. Quality and performance depend on holdings and management, not the NAV number.
Q: How often is NAV calculated?
Once every working day, after the underlying market closes.
Q: Can NAV go negative?
No. NAV represents net assets divided by units, and assets cannot fall below zero.
