Net Asset Value, or NAV, is the price at which you buy and sell units of a mutual fund. Despite being a fundamental concept, NAV is surrounded by misconceptions that lead investors to make poor decisions. One of the most damaging myths is that a fund with a lower NAV is "cheaper" and therefore a better buy. This guide explains what NAV really means, how it is calculated, and why it should not influence your fund selection.
How NAV Is Calculated
NAV represents the per-unit market value of a mutual fund scheme. It is calculated at the end of every business day by taking the total market value of all securities held by the fund, adding any cash and receivables, subtracting liabilities and expenses, and dividing the result by the total number of outstanding units. The formula is straightforward: NAV equals (Total Assets minus Total Liabilities) divided by Total Outstanding Units.
NAV is declared once per day, after market hours. Unlike stock prices that fluctuate throughout the trading day, mutual fund NAV is calculated only at the end of the business day based on closing prices of all holdings.
Why High NAV Does Not Mean Expensive
This is the single biggest myth about NAV. Many investors compare two funds and conclude that the one with a lower NAV is "cheaper." This is completely wrong. NAV is not a stock price. A fund with NAV of Rs 500 is not more expensive than a fund with NAV of Rs 50. The NAV simply reflects the historical growth of the fund since its inception. A fund launched 20 years ago at Rs 10 NAV that has grown to Rs 500 has delivered excellent returns. A new fund launched at Rs 10 NAV has no track record at all.
| Scenario | Fund A (NAV Rs 500) | Fund B (NAV Rs 50) |
|---|---|---|
| Investment Amount | Rs 10,000 | Rs 10,000 |
| Units Allotted | 20 units | 200 units |
| If Fund Grows 10% | NAV becomes Rs 550 | NAV becomes Rs 55 |
| New Portfolio Value | Rs 11,000 (20 x 550) | Rs 11,000 (200 x 55) |
| Absolute Gain | Rs 1,000 | Rs 1,000 |
| Return Percentage | 10% | 10% |
Whether you buy 20 units at NAV Rs 500 or 200 units at NAV Rs 50, a 10 percent return gives you exactly the same Rs 1,000 gain on a Rs 10,000 investment. The number of units is irrelevant. What matters is the percentage return.
NAV vs Stock Price: A Critical Distinction
A stock price is driven by supply and demand in the market and can be overvalued or undervalued relative to the company's intrinsic value. NAV is purely a mathematical calculation based on the market value of the fund's holdings. There is no concept of a mutual fund being "overvalued" or "undervalued" based on its NAV. The NAV accurately reflects what the underlying portfolio is worth at that moment. You cannot find a "bargain" by buying a fund with a lower NAV.
NAV Cut-Off Times You Must Know
SEBI has mandated specific cut-off times for mutual fund transactions. For equity and hybrid funds, if your purchase request and payment are received before 3:00 PM on a business day, you get that day's NAV. If received after 3:00 PM, you get the next business day's NAV. For liquid and overnight funds, the cut-off is 1:30 PM. Understanding these cut-off times is important, especially for lump sum investments where a single day's NAV difference on a large amount can be significant.
How Your SIP Uses NAV
When your monthly SIP amount is debited, the units are allotted based on the NAV of that day (subject to cut-off time rules). If your SIP date is the 5th and the NAV on that day is Rs 100, your Rs 10,000 SIP buys 100 units. Next month, if the NAV drops to Rs 90, the same Rs 10,000 buys 111.11 units. This automatic purchase of more units at lower NAV and fewer units at higher NAV is rupee cost averaging in action.
Common NAV Myths Debunked
- Myth: Lower NAV means better value. Reality: NAV has no bearing on future returns. Focus on fund quality and consistency.
- Myth: NFOs at Rs 10 NAV are cheaper. Reality: A new fund at Rs 10 NAV has zero track record. An established fund at Rs 500 NAV has proven performance.
- Myth: You should wait for NAV to drop before investing. Reality: With SIP, you automatically buy more units when NAV drops. Timing is irrelevant.
- Myth: Dividend payout reduces NAV so it is like getting free money. Reality: Dividend is paid from your own investment and NAV drops by the same amount. It is not free income.
- Myth: Funds with high NAV have limited growth potential. Reality: NAV growth depends on portfolio returns, not NAV level.
Choosing a mutual fund based on its NAV is like choosing a book based on its page number. It tells you nothing about the quality of the content inside. Focus on returns, consistency, and fund management instead.
