The single number every mutual fund investor sees daily - demystified once and for all.
"Price is what you pay. Value is what you get." - Warren Buffett
If you've ever looked at a mutual fund - on any platform, any app, any newspaper - the first number you see is the NAV. It is printed in bold, it moves daily, and for many investors, it is the single most misunderstood number in all of personal finance.
Let's break it down completely.
NAV stands for Net Asset Value. In the simplest possible terms, it is the per-unit price of a mutual fund scheme.
Think of it this way: A mutual fund pools money from thousands of investors and invests it in stocks, bonds, or other securities. At the end of every business day, the fund house calculates the total value of everything the fund owns, subtracts its liabilities (like management fees, operating expenses), and divides the result by the total number of units held by all investors.
The NAV Formula
NAV = (Total Assets − Total Liabilities) ÷ Total Outstanding Units
For example: If a fund has ₹500 Crores in assets, ₹2 Crores in liabilities, and 10 Crore units outstanding → NAV = (500 − 2) ÷ 10 = ₹49.80
Every mutual fund's NAV is calculated at the end of each trading day (usually by 11 PM IST). Here's what goes into it:
This is why you cannot buy or sell a mutual fund at a specific price during the day like a stock. When you place an order before 3 PM, you get that day's NAV. If you place it after 3 PM, you get the next business day's NAV.
This is, without exaggeration, the single most dangerous misconception in mutual fund investing. Let us kill it with an example:
| Fund A (NAV ₹10) | Fund B (NAV ₹500) | |
|---|---|---|
| You invest | ₹10,000 | ₹10,000 |
| Units allotted | 1,000 units | 20 units |
| Fund grows 20% | NAV → ₹12 | NAV → ₹600 |
| Your portfolio value | ₹12,000 | ₹12,000 |
Both funds gave you exactly the same 20% return. The NAV is irrelevant to returns. It's like comparing two pizzas - one cut into 10 slices and the other into 4 slices. The total amount of pizza is what matters, not how many slices you have.
⚠️ Key Takeaway: Never choose a fund based on its NAV being "low" or "high." Always compare returns, consistency, fund manager track record, and expense ratio.
While the absolute NAV number doesn't determine returns, the change in NAV is everything. Here's how it directly impacts you:
When you invest ₹50,000 in a fund with a NAV of ₹250, you receive 200 units. If the NAV rises to ₹300 over time, your 200 units are now worth ₹60,000 - a 20% gain. The NAV's movement directly determines your profit or loss.
When you redeem, you sell units at the prevailing NAV. If you bought 200 units at ₹250 and sell at ₹350, you get ₹70,000 - a ₹20,000 profit. The day's NAV at the time of redemption determines your final payout.
If you invest ₹10,000/month via SIP and the NAV drops from ₹100 to ₹50, you now buy 200 units instead of 100. When the market recovers, all those extra units multiply your wealth. This is rupee-cost averaging in action - and NAV drops are what fuel it.
SIP + Falling NAV = Wealth Accelerator
| Month | NAV (₹) | SIP Amount (₹) | Units Bought |
|---|---|---|---|
| January | 100 | 10,000 | 100 |
| February | 80 | 10,000 | 125 |
| March | 50 | 10,000 | 200 |
| April | 75 | 10,000 | 133 |
| May | 100 | 10,000 | 100 |
| Total | - | ₹50,000 | 658 units |
At ₹100 NAV in May → Portfolio value = ₹65,800. That's a 31.6% return even though the NAV is exactly where it started! The dip did the heavy lifting.
When a mutual fund declares a dividend (now called IDCW - Income Distribution cum Capital Withdrawal), the NAV of the fund falls by the amount of dividend paid per unit. This confuses many investors.
For example: If a fund has a NAV of ₹100 and declares a dividend of ₹5 per unit, the NAV drops to ₹95 the next day. You didn't earn "extra" money - the fund simply took ₹5 from your own investment and handed it back to you. It's like withdrawing cash from your own wallet.
💡 Pro Tip: For long-term wealth creation, always prefer the Growth option over the IDCW option. The Growth option reinvests all gains back into the fund, keeping the compounding engine running at full speed.
Every mutual fund scheme has two variants - Regular and Direct. The Direct plan has a higher NAV than the Regular plan because it doesn't pay distributor commissions, so more money stays invested in the fund.
| Factor | Regular Plan | Direct Plan |
|---|---|---|
| Expense Ratio | Higher (includes commission) | Lower |
| NAV | Slightly lower | Slightly higher |
| Returns over time | Marginally lower | Marginally higher |
| Advisory support | Yes (through distributor) | Self-managed |
The difference in NAV between Regular and Direct widens over time due to the compounding effect of the lower expense ratio in Direct plans. Over 20-30 years, this difference can amount to lakhs of rupees.
If NAV alone doesn't tell the whole story, what should you actually evaluate?
Understanding NAV is just the beginning. Building a well-diversified portfolio tailored to your goals requires expertise. Let Mango Wealth handle the complexity so you can focus on what matters.
