Why a Higher NAV in a Mutual Fund Does Not Mean a Costlier Fund

Think about buying a movie ticket. You might pay Rs 200 for a standard seat or Rs 1,200 for a premium recliner; the number on the stub is irrelevant. Of course, a Rs 1,200 ticket for a film you abandon halfway is a worse deal than a Rs 200 ticket you watch with full enjoyment. Mutual fund NAV works much the same way, and indeed, nearly every first-time SIP investor makes the same mistake: they pick a fund with a lower NAV thinking it is cheaper to buy. That instinct is understandable. It is also incorrect.

What Exactly Is NAV and How Is It Calculated Every Day?

NAV, or Net Asset Value, is the per-unit price of a mutual fund. It is calculated at the end of every business day by dividing the total market value of all securities held by the fund, minus any liabilities, by the total number of units outstanding. In plain terms: NAV = (Total Assets – Total Liabilities) / Total Units. If a fund holds stocks and bonds worth Rs 1,000 crore and has 10 crore units in circulation, the NAV is Rs 100 per unit. SEBI requires every AMC to publish the updated NAV on the AMFI website by 11 PM each business day.

Notice that this number changes every day because the underlying securities change in price every day. Hence, NAV is a trailing score, much like a student’s cumulative marks so far in the academic year. It tells you where the fund has been, not how skilled the fund manager is at picking stocks. A fund with a NAV of Rs 500 is not expensive the way a stock trading at Rs 500 might seem. It simply means the fund has been running for some time and has grown steadily since launch.

Does It Matter Whether You Start With a Rs 200 NAV or a Rs 20 NAV?

No. If both funds deliver the same percentage return, your money grows by exactly the same amount regardless of where the NAV starts, because the number of units you receive adjusts automatically to match your investment amount. This is one of the most persistent myths in beginner investing, and a simple side-by-side illustration clears it up completely.

Suppose you invest Rs 10,000 in two hypothetical funds shown below, clearly labelled as illustration-only examples and not real funds. Fund A has a NAV of Rs 200 per unit and Fund B has a NAV of Rs 20 per unit. After one year, both funds deliver a 15% return on their underlying portfolio of securities.

Metric	Fund A (High NAV)	Fund B (Low NAV)
Starting NAV	Rs 200	Rs 20
Your investment	Rs 10,000	Rs 10,000
Units allotted	50 units	500 units
NAV after 1 year (15% gain)	Rs 230	Rs 23
Value of your holding	Rs 11,500	Rs 11,500
Your gain	Rs 1,500	Rs 1,500

The outcome is identical. Fund A gave you 50 units at a higher price per unit, while Fund B gave you 500 units at a lower price per unit. In both cases, your Rs 10,000 becomes Rs 11,500 after one year. The NAV is simply the denomination, like getting ten Rs 10 notes versus one Rs 100 note; your wallet holds exactly the same total either way.

What Does a Rising or Falling NAV Actually Tell You?

To put this in perspective: a fund at NAV Rs 10 in 2010 that now sits at Rs 180 has delivered roughly 20x growth over fifteen years. That is a record of compounding, not a signal that the fund is expensive to enter today. A new fund launched at Rs 10 in 2024 offers no such history. Picking a fund just because its NAV is low is choosing a blank page over a fund with a proven track record of growing investor wealth.

What Should You Actually Check Before Picking a Mutual Fund?

The key point here is that NAV tells you the current price per unit, not whether a fund is worth buying. Three metrics actually matter when comparing funds within the same category, and none of them is NAV.

Metric	Why It Matters	What to Look For
Expense Ratio	Annual fee deducted daily from NAV. Lower fees mean more return stays with you over time.	Direct plans charge less than regular plans. Compare within the same category.
3-Year and 5-Year CAGR	CAGR (Compounded Annual Growth Rate) shows year-on-year growth, smoothing out short-term market swings.	Compare against benchmark and peer funds across at least one full market cycle.
Category Rank	Consistent top-quartile ranking over multiple years is more meaningful than a single lucky spike.	Check 3-year and 5-year peer rankings on a research platform before committing.

India’s mutual fund industry now manages total assets of over Rs 81 lakh crore, with SIP AUM alone crossing Rs 17 lakh crore in May 2026, representing roughly 21% of total industry assets under management, and the number of SIP contributing accounts has crossed 9 crore (AMFI, June 2026). No wonder SIPs have become the default savings vehicle for millions of Indian households. The investors who build genuine wealth from these accounts focus on CAGR and expense ratio, not the NAV figure on their statement.

Does Buying in a Direct Plan Change the NAV Picture?

Yes, and this is where comparing NAV across plans of the same fund can mislead you. A direct plan and a regular plan of the same scheme invest in identical portfolios, but the direct plan carries a lower expense ratio because there is no distributor commission. Having said that, the direct plan will always show a higher NAV than the regular plan because it retains more returns each year. Choosing the regular plan because its NAV looks lower means paying more to get less, which is clearly the opposite of sound investing. Start a SIP in a direct plan through your AMC’s own website, and use the SIP Calculator on Maxiom Wealth to model how compounding changes across different amounts and time periods.

Frequently Asked Questions About NAV

Does a low NAV mean a fund is new? Not always, but often. A NAV near Rs 10 typically means the fund has not run for long or has not grown much since launch. A high NAV generally signals a longer compounding history, which is a positive indicator, not a reason for concern.

Can NAV fall below the launch price of Rs 10? Yes. If the underlying portfolio loses value during a market downturn, NAV can drop below Rs 10. Checking a fund’s track record across full market cycles matters far more than its current NAV level when deciding where to invest.

Is NAV the same as a share price? They look similar but behave differently. A share price reflects buyer-seller agreement on a stock exchange in real time. NAV is calculated once per day at market close using actual portfolio values, not by trading activity in the fund units themselves.

Should I wait for NAV to fall before investing? No. Timing NAV is not reliable because it moves with the broader market. A SIP removes this guessing by purchasing units at whatever NAV exists on your chosen date each month, averaging your cost automatically over time.

To Sum Up

To sum up: NAV is a daily calculation reflecting a fund’s net worth per unit, not a price tag making a fund cheap or expensive to enter. A higher NAV signals a longer compounding track record; a lower NAV signals a newer or slower-growing fund. Two funds with different NAVs deliver identical rupee gains on the same Rs 10,000 investment when their percentage returns match, as the illustration above shows clearly. What separates a good fund from a mediocre one is the expense ratio, the multi-year CAGR against peers, and consistency of category rank across market cycles. Check those three things, and set the NAV column aside for good.
