Key Takeaways
What Matters Most
- NAV is the per-unit value of a mutual fund’s net assets; a lower NAV does not mean the fund is cheaper.
- Returns depend on percentage change in NAV plus distributions where relevant, not the absolute NAV number.
- NAV is calculated from the value of portfolio assets minus liabilities divided by units outstanding.
- Cut-off times and applicable NAV rules affect transactions; they are operational rules, not valuation signals.
Detailed Explanation
How It Works and What the Number Means
Why ₹10 NAV Is Not ‘Cheaper’ Than ₹100 NAV
Two funds can own identical portfolios but have different NAVs because they launched at different times or have different unit histories. If both portfolios rise 10%, a ₹10 NAV can become ₹11 and a ₹100 NAV can become ₹110; the investor earns the same percentage before costs and other differences.
New fund offers often begin around a stated face value, but that does not make them economically cheaper than established funds. Evaluate the underlying portfolio, mandate, cost and process rather than choosing based on NAV level.
What Changes NAV
Portfolio security prices, accrued income, expenses, realised gains/losses and fund flows all interact with the scheme’s net assets and units. Subscriptions and redemptions generally create/cancel units at the applicable NAV, so they do not by themselves create investment performance for existing holders.
For international or less-liquid assets, valuation timing and market holidays can affect reported NAV movement. Use official AMC/AMFI data and understand the applicable valuation date when comparing returns.
In Practice
How Investors Should Analyse It
This is where the concept moves from a definition to real research. Use these sections to connect the number with filings, business conditions and the other evidence around it.
NAV Is an Accounting Value per Unit, Not a Valuation Multiple
NAV is calculated from the market value of a scheme’s assets, plus receivables and other assets, minus liabilities and accrued expenses, divided by units outstanding. A fund with NAV ₹20 is not inherently cheaper than one with NAV ₹200. If both portfolios rise 10% before costs and flows, each investor’s percentage gain is broadly driven by the portfolio return, not the starting NAV level. New-fund-offer NAVs therefore should not be interpreted like a low share price.
Understand What Moves NAV
Portfolio security prices, interest accruals, corporate actions, expenses, currency movements for overseas assets and distributions can affect NAV depending on the scheme. Subscriptions and redemptions change units and assets but are processed so that existing investors are not supposed to gain simply because more money entered the fund. When analysing historical returns, use adjusted total-return data where appropriate and check the exact plan and option, because direct/regular and growth/distribution variants can have different NAV histories.
Compare returns, not the absolute NAV level
NAV is the accounting value of one unit, so two plans with very different NAVs can deliver nearly identical portfolio performance before differences in expenses. The number of units adjusts to the amount invested. A lower NAV therefore does not provide the valuation advantage that investors sometimes associate with a lower share price. When comparing funds, focus on the underlying portfolio, mandate, benchmark, costs, tracking quality and risk rather than the rupee value of one unit.
Distributions also need care. When a scheme makes an IDCW distribution, the NAV generally falls by the amount attributable to the distribution, subject to market movement and applicable accounting. Looking only at the post-distribution NAV can therefore understate the investor’s total economic return. Use total-return information and the appropriate plan/option when making performance comparisons.
Worked example
See How It Works
Fund A can have NAV ₹20 and Fund B NAV ₹200 while owning similar portfolios. Investing ₹10,000 simply buys more units of Fund A; the lower NAV does not make it economically cheaper.
Common Mistakes
Where Investors Can Go Wrong
- Choosing a fund because its NAV is numerically low.
- Comparing NAV levels across unrelated schemes.
- Ignoring distributions/IDCW when measuring total return.
- Using stale NAV dates in performance comparisons.
Investor Checklist
Check These Before Deciding What It Means
- Check scheme/plan/option identity.
- Confirm NAV date.
- Compare percentage returns, not NAV levels.
- Account for IDCW/distributions where relevant.
- Review portfolio and expense ratio.
- Use official NAV sources.
Limits
When This Can Mislead You
NAV does not reveal whether the underlying portfolio is cheap, expensive, risky or suitable. It is a unit-accounting value and should not be interpreted like a share price.
Apply the Lesson
Test the Idea on Real Numbers
Use the concept to ask better questions about a real company, fund or cash-flow pattern. Verify material facts independently before relying on them.
Questions People Commonly Ask
Is a ₹10 NAV fund cheaper than a ₹100 NAV fund?
No. NAV level alone says nothing about valuation; percentage ownership of the underlying assets is what matters.
Why does NAV fall after a distribution?
When value leaves the scheme as a distribution, NAV generally adjusts to reflect the reduced assets, subject to applicable accounting and tax treatment.
Can two plans of the same scheme have different NAVs?
Yes. Different expense structures and historical cash flows can lead to different NAV levels.
