The tangible book value formula

The full formula has five inputs, all from the balance sheet:

Tangible book value = total shareholders' equity minus preferred equity minus noncontrolling interests minus goodwill minus other intangible assets

Tangible book value per share (TBVPS) = tangible book value / common shares outstanding

Price to tangible book (P/TBV) = share price / TBVPS

Each subtraction has a reason.

  • Preferred equity is a claim that ranks ahead of common shareholders. It is not theirs.
  • Noncontrolling interests are the share of consolidated subsidiaries owned by outside investors. Consolidated equity includes them, but common holders of the parent do not own them.
  • Goodwill is the amount paid in past acquisitions above the fair value of the identifiable net assets acquired. It cannot be sold on its own.
  • Other intangible assets include acquired brands, trademarks, customer relationships, patents, licenses and capitalized software. Some have resale value, but most are hard to separate from the business that uses them.

If the balance sheet shows "total stockholders' equity attributable to the company," that line already excludes noncontrolling interests. Start there and skip that step.

How to calculate it step by step

The inputs come from the consolidated balance sheet in the latest 10-Q or 10-K. The 10-Q is due 40 days after quarter end for large accelerated and accelerated filers and 45 days for all other registrants, so the most recent quarter is rarely more than a few months old. Our guide on how to read a 10-Q for special situations shows where each line sits.

  1. Find total stockholders' equity. Use the line attributable to the parent company if one is shown.
  2. Subtract preferred stock. It appears within equity, often near the top of the equity section.
  3. Subtract goodwill. It is usually its own line in the asset section.
  4. Subtract other intangible assets, net. Use the net figure after amortization. Check the notes for capitalized software or licenses that sit inside "other assets."
  5. Get the share count. Use common shares outstanding from the cover page, which is dated close to the filing date and is usually the latest figure available.
  6. Divide. Tangible book value divided by shares gives TBVPS. Price divided by TBVPS gives P/TBV.

Worked example

On a price-to-book screen, Company A looks deeply discounted. On tangible book, it does not. The whole discount depends on whether the two acquired businesses are still worth what Company A paid for them. Our price-to-book ratio explainer covers that judgment in more detail.

Now suppose Company A records a $60 million goodwill impairment next quarter. Book value falls to $290 million, or $19.33 per share, and P/B rises to about 0.72. Tangible book value stays at $165 million because goodwill was never in it. The share price may not move much either, because the market had likely already discounted those acquisitions. This is the main reason analysts prefer tangible book for acquisitive companies: it does not change when management finally admits a past deal was overpriced.

What moves tangible book value per share

Tangible book is not static. Five things change it from one quarter to the next.

Retained earnings

Profits that are not paid out add to tangible equity. Losses subtract from it. A company losing 10% of its tangible equity each year will see TBVPS approach a low share price quickly, so a P/TBV below 1.0 means little if the losses continue.

Dividends

Dividends paid reduce equity and tangible book by the same amount. That is a transfer to shareholders, not a loss of value, but it lowers the per-share figure you compare with price.

Buybacks

A repurchase below TBVPS raises tangible book per share for the remaining holders. A repurchase above TBVPS lowers it. A company buying back stock at three times tangible book is spending tangible equity to reduce share count, which can push tangible book toward zero over time.

Acquisitions

When a company buys another business for cash, the cash leaves the balance sheet and is replaced partly by goodwill and intangibles. Tangible book falls even though total book value may barely change. Analysts call this tangible book dilution and often estimate an "earn-back period": how many years of retained earnings it takes to restore TBVPS to its pre-deal level.

Unrealized gains and losses

For banks and insurers, unrealized gains and losses on securities classified as available for sale run through accumulated other comprehensive income, which is part of equity. Rate moves can shift tangible book materially in a single quarter without any change in operating results.

Tangible book sits between two stricter and looser floors.

  • Book value is looser. It counts acquired goodwill and intangibles at cost.
  • Net current asset value is stricter. It counts only current assets minus all liabilities and ignores plants, property and equipment.
  • Net cash is stricter still. Our guide to net cash per share covers stocks priced below the cash on their balance sheets.

Tangible book also differs from enterprise value. Enterprise value is a market measure of what it would cost to buy the whole business, including debt. Tangible book is an accounting measure of what the equity holders own in separable assets. A company can trade below tangible book and still carry a high enterprise value if it has a lot of debt.

For a company winding down, tangible book is a starting point, not an answer. A liquidation play values each asset at its expected sale price, after costs and time, which can be well below carrying value.

When tangible book is the right lens

Use tangible book as a primary measure when most of these hold:

  • If the company is a bank, insurer or other financial firm, use P/TBV with return on tangible common equity as your starting pair.
  • If the company has grown through acquisitions, compare P/B with P/TBV to see how much of the discount rests on goodwill.
  • If the stock trades below book and management is selling assets or reviewing alternatives, use TBVPS as a rough floor for the sale.
  • If the company is asset-light, such as software or services, set tangible book aside and use earnings and cash flow measures instead.
  • If tangible book is negative, drop P/TBV and value the business on cash flow.

Dombey's published research applies a tangible book check to every below-book name before a catalyst; see the research archive.

Where this goes wrong

Tangible book removes the least reliable assets, but it does not make the rest reliable.

  • Tangible does not mean liquid. Specialized equipment, slow-moving inventory and real estate in a weak market can sell well below carrying value. Read the inventory and property notes.
  • Deferred tax assets stay in. They only have value if the company earns enough taxable income to use them. A loss-making company with large deferred tax assets has a softer tangible book than the number suggests.
  • Real but unrecorded assets are missed. Internally built brands, software and customer relationships are generally expensed, not capitalized. Tangible book understates the value of businesses built that way, and stating it for them can mislead.
  • Old cost can understate assets. Land bought decades ago may be worth far more than its carrying value. Tangible book will not show that.
  • Off-balance-sheet claims reduce it. Litigation, guarantees and purchase commitments disclosed in the notes can reduce economic equity without appearing as liabilities. The 10-K guide shows where these disclosures sit.
  • Cheap can stay cheap. A stock below tangible book with low returns and no catalyst can stay there for years.

Common mistakes

  • Using total equity without removing noncontrolling interests. This overstates what the parent's common holders own, sometimes by a wide margin.
  • Using an old share count. Buybacks and issuance since the balance sheet date change TBVPS. Use the cover-page count.
  • Ignoring intangibles hidden in other lines. Capitalized software and licenses sometimes sit in "other assets." Check the notes.
  • Reading P/TBV without returns. A bank at 0.8 times tangible book earning 4% on tangible equity is not obviously cheaper than one at 1.3 times earning 14%.
  • Comparing across industries. A P/TBV that is low for a bank may be normal for a manufacturer and meaningless for a software firm.

The bottom line

Tangible book value is common equity minus goodwill and other intangible assets, and it is calculated in a few lines from the balance sheet. It gives a stricter floor than book value and does not move when a company writes down goodwill, which makes it the better measure for banks and acquisitive companies. It still includes assets that may sell for less than their carrying value and misses value that never reached the balance sheet. Read it per share, track it over several quarters, and pair it with the return the company earns on its tangible equity.
