Net asset value (NAV) is the value of a fund’s assets minus its liabilities, usually expressed on a per-share or per-unit basis.
NAV is central to fund pricing because it estimates what one share of a pooled investment vehicle represents economically. It is especially important for mutual funds, ETFs, closed-end funds, and other pooled vehicles.
Key Takeaways
- NAV starts with total assets and subtracts liabilities.
- NAV per share divides that net value by shares or units outstanding.
- Traditional mutual funds usually transact at end-of-day NAV.
- ETFs and closed-end funds can trade at market prices that differ from NAV.
- NAV is a valuation measure, not a guarantee that the fund is safe, liquid, or suitable.

Assets can include securities, cash, receivables, and other portfolio assets. Liabilities can include accrued fees, payables, borrowing, and other obligations.
NAV vs. Market Price
| Concept | Meaning | Where it matters |
|---|
| NAV | Asset-minus-liability value per share or unit. | Mutual fund pricing, ETF valuation, fund accounting. |
| Market price | Price at which buyers and sellers trade on an exchange. | ETFs, closed-end funds, exchange-traded products. |
| Premium to NAV | Market price is above NAV. | Buyers are paying more than the underlying value estimate. |
| Discount to NAV | Market price is below NAV. | Sellers are accepting less than the underlying value estimate. |
For an open-end mutual fund, investor transactions usually occur at NAV. For an ETF or closed-end fund, the market price can differ from NAV because shares trade between market participants.
Why NAV Matters
NAV helps investors and analysts:
- price mutual fund purchases and redemptions
- compare ETF market prices with underlying portfolio value
- track fund performance over time
- identify premiums or discounts in exchange-traded funds
- separate asset value from investor trading behavior
NAV is not the same as total return. Distributions, fees, taxes, and reinvestment affect the investor’s realized result.
Common Mistakes
- Treating NAV as the same thing as market price for every fund structure.
- Assuming a fund with a lower NAV is cheaper than a fund with a higher NAV.
- Ignoring distributions, fees, and tax effects when comparing NAV changes.
- Treating stale or hard-to-value holdings as if NAV were perfectly precise.
- Using NAV alone to judge whether a fund is suitable.
When NAV Can Be Less Precise
NAV depends on the valuation of the assets and liabilities inside the fund. It can be less straightforward when a fund holds:
- thinly traded securities
- private or hard-to-value assets
- international securities priced in different time zones
- derivatives or structured exposures
- illiquid bonds or distressed securities
In those cases, review the fund’s valuation policy, holdings, liquidity, and disclosure documents.

FAQs
Is NAV the same as market price?
Not always. Mutual fund transactions usually occur at NAV, but ETFs and closed-end funds can trade at market prices above or below NAV.
Does a lower NAV mean a fund is cheaper?
No. A lower NAV does not by itself mean better value. The fund’s holdings, strategy, fees, risks, and return prospects matter more.
Why do liabilities matter in NAV?
Liabilities reduce the value available to shareholders. NAV measures the residual value after obligations are deducted from the asset pool.
- Mutual Fund: Fund structure that commonly buys and redeems shares at NAV.
- Exchange-Traded Fund: Pooled vehicle whose market price may differ from NAV.
- Closed-End Fund: Fund structure where premiums and discounts to NAV are especially important.
- Portfolio Value: Value of the underlying holdings that feed into NAV.
- Market Price: Exchange price that may differ from NAV for traded funds.
