Price to tangible book value (PTBV) is a valuation ratio that compares a company’s market price to the portion of its book value made up of physical, tangible assets. Intangible assets—goodwill, patents, trademarks, and other intellectual property—are excluded. PTBV is used to help judge how the market values the company’s hard assets relative to what those assets are carried for on the balance sheet.

Key idea in one line
– PTBV = Market price per share ÷ Tangible book value per share (or Market capitalization ÷ Tangible book value). It indicates how much investors are willing to pay for each dollar of a company’s tangible net assets.
Why PTBV matters
– PTBV is most useful for capital‑intensive companies with significant machinery, inventory, land, and buildings (manufacturers, energy producers, utilities, miners).
– Because it strips out intangible assets, PTBV can be a more conservative measure of liquidation value than price-to-book (P/B).
– PTBV is less meaningful for businesses whose value comes mainly from intangibles (software, pharma, internet platforms).
How to calculate PTBV — Formula and steps
1) Gather data from the most recent balance sheet and market data:
• Total assets
• Total liabilities
• Shareholders’ equity (or compute assets − liabilities)
• Intangible assets and goodwill (line items on the balance sheet)
• Preferred equity (if any)
• Shares outstanding
• Current market price per share (or market capitalization)
2) Compute tangible book value (TBV) for common shareholders:
• Tangible book value (absolute) = Total shareholders’ equity − Intangible assets − Goodwill − Preferred equity (if you want TBV attributable to common shareholders).
• Alternative formulation: TBV = (Total assets − Intangible assets − Goodwill) − Total liabilities.
• Note: If there are other noncontrolling interests or adjustments (e.g., accumulated other comprehensive income that you want to treat differently), adjust accordingly.
3) Compute tangible book value per share (TBVPS):
• TBVPS = Tangible book value ÷ Shares outstanding (use diluted shares if you want a conservative estimate).
4) Compute PTBV:
• PTBV = Market price per share ÷ TBVPS
• Or equivalently: PTBV = Market capitalization ÷ Tangible book value (absolute).
Worked example (General Motors, using numbers from Investopedia and company filings)
– Tangible book value (quarter ending June 30, 2023) ≈ $71 billion (Investopedia calculation: total net assets $276B − $5B goodwill/intangibles − $200B liabilities).
– Shares outstanding ≈ 1.4 billion → TBVPS ≈ $71B ÷ 1.4B = $50.7.
– Closing price per share (last trading day of 2023) = $35.72.
– PTBV = $35.72 ÷ $50.7 ≈ 0.70 (i.e., stock trading at 0.7× tangible book).
Interpreting PTBV
• PTBV 1.0: Market is pricing in growth prospects, intangible value not on the balance sheet, superior profitability, or scarcity premium.
Important caveats and limitations
• Historical cost accounting: Balance sheet values are typically historical cost, not current market values. Long‑held land and older assets may be carried at much lower cost than replacement value, or in some cases higher (if impairments haven’t been taken).
– Intangible value omitted: For many modern companies, important value drivers (brands, software, R&D, customer relationships) are intangible and excluded from TBV, making PTBV misleadingly high.
– Industry suitability: PTBV is most relevant for hard‑asset industries (manufacturing, mining, utilities). It is generally not meaningful for technology, service, or intellectual‑property‑centric firms.
– Off‑balance‑sheet items and accounting differences: Operating leases, pension obligations, contingent liabilities, and IFRS vs. GAAP treatments can affect the true economic book value. Make adjustments where material.
– Liquidation sequencing: In a liquidation, common shareholders are paid last, so TBV is a theoretical floor but not necessarily realizable.
– One metric among many: PTBV shouldn’t be the sole determinant of investment decisions—use alongside cash flow, earnings, ROE, debt metrics, and qualitative analysis.
When to use PTBV (practical guidance)
– Use PTBV when analyzing:
• Capital‑intensive firms with significant physical assets (auto manufacturers, oil & gas refiners, heavy industry).
• Situations where liquidation or asset‑replacement value is a relevant concern.
• Value screens looking for companies trading below tangible book value (possible deep value opportunities).
– Avoid relying on PTBV alone for:
• Tech, biotech, media, or other IP‑driven businesses.
• Companies with large, difficult‑to‑value off‑balance‑sheet liabilities.
Practical step‑by‑step checklist for investors or analysts
1) Select the company and peer group (same industry, similar business model).
2) Pull the latest balance sheet (company 10‑Q or 10‑K) and note:
• Total assets, intangible assets, goodwill, total liabilities, shareholders’ equity, preferred stock amount.
3) Decide on share count: basic vs diluted (diluted gives a conservative TBVPS).
4) Calculate TBV and TBVPS (see formula above).
5) Get the current market price or market cap from a reliable source (exchange, financial data provider).
6) Compute PTBV.
7) Compare PTBV to:
• The company’s historical PTBV trend (are we at a low or high relative to history?).
• Peers’ PTBVs in the same industry.
8) Diagnose differences:
• If PTBV is low versus peers, check for distressed signals, asset impairments, or hidden liabilities.
• If PTBV is high, check for intangibles and future growth drivers.
9) Adjust where appropriate:
• Subtract preferred stock to get common TBV.
• Consider adding back off‑balance sheet assets or adjusting land values if material.
• Account for pension deficits, lease obligations, environmental liabilities, etc.
10) Use PTBV along with other valuation ratios (P/E, EV/EBITDA), cash flow analysis, and qualitative factors (management quality, competitive positioning).
Screening tips (practical examples)
– Conservative value screen: industrial companies with PTBV < 0.8 but positive operating cash flow and manageable leverage.
– Deep value screen: PTBV < 0.5 — flag for potential bargain hunting but require close due diligence on asset quality and liabilities.
– Avoid applying the same PTBV filters to technology and service sectors.
How PTBV differs from Price‑to‑Book (P/B)
– P/B = Market price per share ÷ Book value per share (book value includes intangible assets).
– PTBV excludes intangible assets and goodwill, so it is usually lower than P/B for firms with meaningful intangibles.
– Both measure market price relative to book equity, but PTBV is a more conservative, tangible‑asset‑focused variant.
Common adjustments analysts make
– Remove goodwill and identified intangibles (as per PTBV definition).
– Subtract preferred equity to isolate common shareholders’ TBV.
– Treat lease liabilities and right‑of‑use assets consistently (IFRS/GAAP differences can create distortions).
– Consider replacement value for old long‑held land or buildings if replacement value is a better indication of real asset value.
– Adjust for deferred tax assets/liabilities if they materially affect recoverable assets.
Practical example of a due diligence workflow using PTBV
1) Run an initial screen for PTBV < 1 in the industrials sector.
2) For candidates, download the 10‑Q/10‑K and compute TBV yourself (don’t rely only on screen outputs).
3) Check asset composition: how much is inventory, plant, land, receivables? Are inventories obsolete?
4) Review notes for contingencies, lease obligations, pension deficits, and off‑balance‑sheet arrangements.
5) Evaluate cash generation: a low PTBV firm that still generates free cash flow is more attractive than one that does not.
6) Talk to management commentary about asset utilization, planned capex, and restructuring charges.
7) Compare to peers and historical PTBV trend.
8) If everything checks out and valuation thesis holds, model upside scenarios and risk/recovery in liquidation situations.
Frequently asked questions (brief)
Q: Is PTBV a measure of liquidation value?
A: It’s an accounting‑based proxy for tangible liquidation value but often overstates realizable recovery because assets could fetch less in a distressed sale and creditors have priority.
Q: If PTBV is very low, is the stock a buy?
A: Not automatically. Low PTBV can signal distress, accounting issues, or low asset quality. It requires deeper due diligence.
Q: Should I use book value or replacement value for assets?
A: Book value is what the balance sheet shows and is the basis for PTBV. For investment decisions, estimating replacement or fair market value can be useful, especially for long‑held real estate or specialized equipment.
The bottom line
– PTBV is a conservative valuation tool that strips out intangible assets and focuses on tangible net assets. It is particularly useful for capital‑intensive businesses where hard assets matter, and less useful for intangible‑asset‑driven firms. Used properly—with adjustments and alongside other metrics—it can be a helpful part of a broader valuation and due diligence toolkit.
