Introduction
When it comes to mutual fund investing, one of the most frequently used terms is Net Asset Value (NAV). Investors often see NAV quoted daily, but many misunderstand what it actually represents. Some assume that a higher NAV means a better fund, while others believe NAV is directly linked to profitability. In reality, NAV is simply a way of measuring the value of a fund’s assets at a given point in time.
In this blog, we’ll break down what NAV means, how it is calculated, why it matters for mutual fund investors, and the myths surrounding it. By the end, you’ll have a clear picture of how Net Asset Value works and how to use it wisely in your investment journey.
What is Net Asset Value (NAV)?
NAV, or Net Asset Value, is the per-unit price of a mutual fund. It represents the total value of a fund’s assets minus its liabilities, divided by the number of units outstanding. In simpler terms, Net Asset Value tells you the price at which you buy or sell one unit of a mutual fund.
It is similar to the market price of a stock. However, unlike stocks, mutual fund NAVs are calculated only once a day after market hours, based on the closing prices of the securities the fund holds.

Formula for NAV Calculation
The formula for calculating Net Asset Value is straightforward:
NAV = (Total Assets – Total Liabilities) ÷ Total Number of Units Outstanding
- Total Assets include the market value of all securities (like stocks and bonds), cash, receivables, and accrued income.
- Liabilities include expenses, management fees, and payables.
- Units Outstanding are the total units that investors currently hold in the fund.
For example:
If a fund has assets worth ₹100 crore, liabilities of ₹5 crore, and 10 crore units outstanding, the NAV would be:(100 – 5) ÷ 10 = ₹9.5 per unit.
Why is NAV Important?
NAV is important because it gives investors a transparent picture of the value of their investment at any given time. However, it is crucial to understand what Net Asset Value does and does not indicate:
- Entry and Exit Price: NAV determines the price at which you buy or redeem mutual fund units.
- Valuation Benchmark: It helps track the fund’s growth over time.
- Transparency: Daily Net Asset Value disclosures ensure transparency in fund management.
But NAV alone does not determine the performance or quality of a fund. Two funds with different NAVs may deliver the same returns depending on how their portfolios are managed.

NAV vs. Fund Performance
Many new investors mistakenly believe that a lower Net Asset Value means the fund is “cheaper” and hence better. In reality, NAV should not be confused with performance.
For example:
- Fund A has an NAV of ₹15 and Fund B has an NAV of ₹150. If both grow by 10% in a year, Fund A will rise to ₹16.5 and Fund B to ₹165. The percentage gain is the same.
Thus, returns depend on the underlying assets and fund management, not the absolute NAV.
Factors Affecting NAV
Several factors influence the daily change in a mutual fund’s NAV:
- Market Movements – If the securities in the portfolio rise in value, NAV increases, and vice versa.
- Dividends or Interest – Income earned from holdings adds to the fund’s assets, increasing NAV.
- Expenses and Liabilities – Management fees and other costs reduce NAV.
- Inflows and Outflows – Buying and redeeming of units affect the number of units but not directly the NAV per unit.
NAV in Different Types of Funds
- Equity Funds: NAV fluctuates daily due to stock market volatility.
- Debt Funds: NAV moves more steadily, reflecting interest income and bond prices.
- Hybrid Funds: NAV depends on both equity and debt performance.
- Index Funds: NAV mirrors the movement of the index it tracks.
How Should Investors Use NAV?
Instead of focusing only on NAV, investors should look at:
- Past performance of the fund compared to its benchmark.
- Expense ratio, as lower expenses improve net returns.
- Fund manager’s track record and investment style.
- Portfolio diversification to reduce risk.
NAV is just a tool to calculate the value of units, not a measure of future success.
NAV in SIPs and Lump-Sum Investments
When investing through Systematic Investment Plans (SIPs), NAV plays a role in determining how many units you get each month. If NAV is lower, you buy more units; if it’s higher, you buy fewer. Over time, this averaging process balances your cost.
In lump-sum investments, you purchase units at the prevailing NAV on the investment date.
Thus, NAV affects the number of units you hold, but overall returns are determined by how well the fund’s investments perform.
Conclusion
Net Asset Value (NAV) is a crucial concept for mutual fund investors, but it is often misunderstood. NAV simply reflects the per-unit value of a fund’s assets at the end of each trading day. While it determines the buy and sell price of units, it does not indicate whether a fund is cheap, expensive, or high-performing.
For smart investing, focus on fund performance, portfolio quality, expense ratio, and long-term goals, rather than just NAV levels. By understanding the true meaning of NAV and using it correctly, investors can make more informed decisions and achieve better financial outcomes.
