Net Asset Value (NAV)

Net asset value (NAV) is the total value of an entity's assets minus its total liabilities. It represents the net worth of a fund, company, or investment vehicle at a specific point in time. NAV is most commonly associated with mutual funds and ETFs, where it determines the price at which investors buy or redeem shares.

How net asset value works

The formula is straightforward:

NAV = Total Assets − Total Liabilities

For a mutual fund, total assets include the market value of all portfolio securities, cash, and accrued income. Total liabilities include fees and expenses payable. The result is divided by the number of shares outstanding to produce the per-share NAV, calculated at the end of each trading day.

For example, if a fund holds $50 million in assets and carries $2 million in liabilities, its NAV is $48 million. With 4 million shares outstanding, the per-share NAV is $12.00.

For a private company or LLC, the same formula applies using balance sheet figures rather than a securities portfolio, producing a measure of the business' book value.

Why net asset value matters

For mutual fund investors, NAV is the definitive pricing mechanism: all purchase and redemption transactions execute at the NAV calculated at each day's close, not at intraday market prices.

For business owners, NAV informs equity distribution, business valuation during a sale or merger, and the calculation of ownership interest among multiple stakeholders. It also plays a role in estate planning, where the NAV of a business interest often determines its taxable value when transferred to heirs or held in trust.

Common uses

• Mutual funds and ETFs: Per-share NAV sets the price for all end-of-day buy and sell orders.
• Real estate investment trusts (REITs): Investors compare a REIT's market price to its NAV to assess whether shares trade at a premium or discount to the underlying property values, net of debt.
• Private equity and hedge funds: NAV measures current fund value and serves as the basis for calculating management fees and performance compensation.
• Business valuation: For asset-heavy businesses, real estate holding companies, and manufacturers, NAV provides a starting point for determining the business' value on paper.

Key limitations

NAV reflects book value, not market value. It does not capture intangible assets such as goodwill, brand recognition, or proprietary technology, which can represent a significant portion of a company's actual worth. For service or technology businesses, NAV may substantially understate what a buyer would pay.

Asset values on a balance sheet may also reflect historical cost rather than current market value, making NAV an imperfect proxy for liquidation or fair market value. When using NAV in a sale, dissolution, or equity restructuring, supplement it with other methods such as discounted cash flow analysis or comparable market transactions.

FAQs about NAV

Does a higher NAV mean a mutual fund is a better investment?

No. Per-share NAV reflects current holdings divided by shares outstanding, not fund quality or performance potential. Two funds with identical portfolios but different share counts will have different NAVs, making the absolute figure an unreliable basis for comparison.

Why can an ETF's market price differ from its NAV?

Exchange traded funds (ETFs) trade on exchanges throughout the day, so their market price is determined by real-time supply and demand rather than a single end-of-day calculation. This causes ETFs to trade at a premium or discount to NAV.

When is NAV insufficient for valuing a private business?

NAV works best for asset-heavy businesses where the balance sheet closely approximates sale value. For businesses driven by customer relationships, recurring revenue, or proprietary processes, NAV will typically understate what a buyer would pay, making earnings-based or market-comparable approaches necessary.
