Net Asset Value (NAV)
Executive Summary
Key Takeaways
- ✓ NAV is the fair value of a company's assets minus its liabilities, the specific output of an asset-based valuation.
- ✓ NAV is the standard primary valuation basis for real estate companies, REITs, and investment funds.
- ✓ NAV per share is calculated by dividing total NAV by diluted shares outstanding and is the standard benchmark against which a real estate company's or fund's trading price is compared.
- ✓ A company trading materially below its NAV per share is described as trading at a discount to NAV; above, a premium to NAV.
- ✓ Building a defensible NAV requires independently sourced, current fair values for each material asset, not book (historical cost) values.
Definition¶
Net Asset Value (NAV) is the fair value of a company's assets minus the fair value of its liabilities. It is the specific numerical output produced by an asset-based valuation, and is most commonly used as the primary valuation basis for real estate companies, real estate investment trusts (REITs), and investment funds.
Formula¶
Net Asset Value = Fair Value of Assets - Fair Value of Liabilities
NAV per Share = Net Asset Value / Diluted Shares Outstanding
Why NAV Is the Primary Metric for Real Estate and REITs¶
A real estate company's or REIT's value is substantially the fair value of its underlying property portfolio. Because individual properties can be independently appraised, or their value estimated by capitalizing net operating income at a market-observed capitalization rate, an asset-by-asset NAV build is generally a more direct and reliable indicator of value than a consolidated earnings multiple or a single blended DCF across a diversified property portfolio. NAV per share is the standard benchmark against which a listed real estate company's or REIT's actual trading price is compared, and the resulting gap is described as a discount or premium to NAV.
Building NAV for an Investment Fund¶
For an investment fund or holding company, NAV is built from the fair value of the fund's underlying holdings — typically market value for listed securities, and appraised or model-based fair value for unlisted investments — less the fund's liabilities, including any fund-level debt and accrued fees. NAV per share (or per unit) is a standard, frequently published metric for open- and closed-end investment funds.
Discount and Premium to NAV¶
A company's or fund's actual market trading price frequently diverges from its calculated NAV per share:
- Trading at a discount to NAV — the market price is below NAV per share, which can reflect illiquidity of the underlying assets, governance or management concerns, leverage risk, tax inefficiency of a hypothetical liquidation, or market skepticism about the stated asset valuations
- Trading at a premium to NAV — the market price is above NAV per share, which can reflect a market view that management adds value beyond the current asset base, growth expectations not captured in a static NAV snapshot, or scarcity value
A persistent or widening discount to NAV is commonly investigated as a potential valuation or governance signal, though it is not automatically evidence of an error in either the NAV calculation or the market price.
Audit Considerations¶
- Confirm each material asset in the NAV build is valued using a current, independently sourced fair value (appraisal, market quote, or a documented capitalization methodology), not book value
- Confirm liabilities deducted include all interest-bearing debt at fair or carrying value as appropriate, and any material off-balance-sheet or contingent liabilities
- Confirm the diluted share count used for NAV per share reflects outstanding dilutive securities consistently with how equity value is treated elsewhere in the model
- Where NAV is compared to a market trading price to assess a discount or premium, confirm the comparison uses a consistent valuation date for both figures
Common Errors¶
| Error | Description | Risk |
|---|---|---|
| Book value used instead of fair value | Underlying assets summed at depreciated historical cost rather than current appraised or market value | Materially understates NAV for long-held real estate or investments |
| Stale appraisal dates | Individual property or investment valuations not refreshed to a consistent, current valuation date | NAV does not reflect current market conditions |
| Debt at book rather than fair value | Fair-valued debt not used where market interest rates have moved materially from the debt's coupon | NAV misstates the true net liability position |
| Basic rather than diluted share count | NAV per share calculated without dilutive securities included | Overstates NAV per share |

Frequently Asked Questions
What is Net Asset Value (NAV)?
The fair value of a company's assets minus the fair value of its liabilities — the specific numerical result produced by an asset-based valuation, most commonly used for real estate companies, REITs, and investment funds.
How is NAV per share calculated?
Total Net Asset Value divided by diluted shares outstanding, producing a per-share value that is compared directly against the company's actual trading price to assess whether the market is pricing the shares at a discount or premium to the underlying asset value.
Why is NAV the primary valuation metric for REITs?
Because a REIT's value is substantially the fair value of its underlying real estate portfolio, which can be independently appraised or capitalized property by property, making an asset-based NAV build a more direct and reliable indicator of value than a consolidated earnings multiple or DCF.
What does "trading at a discount to NAV" mean?
That a company's market share price implies a total equity value below its calculated NAV per share — the market is pricing the shares below the appraised or fair value of the underlying net assets, which can reflect illiquidity, governance concerns, leverage risk, or a market view that the stated asset values are optimistic.
How is NAV built up for a real estate company?
By independently valuing (via appraisal or capitalization of net operating income at a market cap rate) each property in the portfolio, summing the resulting gross asset value, and deducting total liabilities including debt, to arrive at net asset value, described further on the Asset-Based Valuation glossary page.
How does NAV differ from book value of equity on the balance sheet?
Book value of equity reflects assets at historical cost less accumulated depreciation. NAV revalues each material asset to current fair value, which for real estate and long-held investments often departs materially, and usually upward, from depreciated book value.

Asset-Based Valuation
Asset-based valuation values a business as the fair value of its underlying assets less its liabilities, rather than as a function of its earnings or cash-generating capacity. It is the practical implementation of the asset-based approach, one of the three classical valuation approaches alongside the income approach (DCF) and the market approach (comparable company analysis and precedent transactions). Asset-based valuation is most relevant for asset-heavy, holding-company, investment-fund, or liquidation scenarios, where the fair value of specific, often independently appraisable assets is a more reliable indicator of value than a going-concern earnings or cash flow forecast.
Equity Value
Equity value is the value of a company attributable specifically to its equity holders, as distinct from enterprise value, which represents the value of the whole operating business attributable to all capital providers combined. Equity value is derived from enterprise value by deducting net debt, minority interests, and preferred stock, and adding back non-operating assets. Equity value divided by diluted shares outstanding produces value per share, the figure most directly comparable to a company's quoted share price.
Enterprise Value (EV)
Enterprise value (EV) is the total value of a company's core operating business, independent of its capital structure — it represents what the business as a whole is worth to all capital providers combined, before distinguishing between debt and equity claims. Enterprise value is the direct output of discounting unlevered free cash flow (FCFF) at WACC. To move from enterprise value to the value attributable to equity holders specifically, net debt, minority interests, and other non-operating adjustments must be deducted — the enterprise-to-equity bridge.
