What Is Goodwill in Accounting? Calculation and Impairment

By Markets & Investing DeskUpdated Nov 10, 2026

Definition

Goodwill is an intangible asset a buyer records when it acquires a business for more than the fair value of that business's identifiable assets minus its liabilities.

Key takeaways

Goodwill equals the purchase price minus the fair value of identifiable assets acquired less liabilities assumed.
The more value a buyer assigns to identifiable intangibles such as brands, the smaller the goodwill figure becomes.
Public companies test goodwill for impairment at least annually, and a write-down cannot be reversed later.
Since 2014, U.S. private companies may amortize goodwill straight-line over up to 10 years instead.

Goodwill in accounting is an intangible asset that a buyer records when it acquires a business for more than the fair value of that business’s identifiable net assets. It arises only from an acquisition. It is the part of the purchase price that cannot be assigned to anything the buyer can separately identify and value, such as cash, inventory, equipment, patents, customer contracts and trademarks, net of the debts and other liabilities assumed. The leftover reflects things like an assembled workforce, expected synergies, market position and the earning power of the business as a going concern.

What Is Goodwill in Accounting?

Goodwill sits on the acquirer’s balance sheet among long-term assets, usually as its own line next to “Intangible assets, net,” because it behaves differently from other intangibles.

A patent, a licence or a customer list can be identified, valued on its own and often sold or licensed separately. Goodwill exists only as part of the acquired business as a whole, so it cannot be sold independently. It also has an indefinite useful life, while most identifiable intangibles have finite lives and are amortized.

The rules sit mainly in ASC 805 (business combinations) and ASC 350 (goodwill and other intangibles) under U.S. GAAP, and in IFRS 3 and IAS 36 under international standards. Both treat goodwill as a residual: whatever the purchase price exceeds after every identifiable item has been valued.

How Goodwill in Accounting Works

When one company buys another, the buyer performs a purchase price allocation. Every identifiable asset and liability of the target is remeasured to fair value at the acquisition date. This is a different exercise from reading the target’s own books:

Book values get replaced. Equipment carried at depreciated cost or land bought decades ago is restated at current fair value.
New intangibles appear. Brands, customer relationships, technology and order backlogs that the target built itself and never recorded are recognized if they meet the identifiability criteria.
Liabilities are included at fair value. This covers debt, leases, qualifying contingent obligations and deferred taxes created by the fair value adjustments.

Only after this allocation is goodwill determined. The more value the buyer attaches to identifiable intangibles, the smaller the goodwill figure.

Calculating Goodwill in Accounting

The basic goodwill formula is:

Goodwill = P − (A − L)

where:

P = purchase price (the consideration transferred, which can include cash, shares and the fair value of any contingent payments)
A = fair value of identifiable assets acquired
L = fair value of liabilities assumed

Hypothetical example. Buyer Co. acquires 100% of Target Co. for $500 million in cash. Target’s own balance sheet shows net assets of $250 million. During the purchase price allocation, the buyer values the identifiable items as follows:

Item	Fair value
Working capital and property, plant and equipment	$500 million
Customer relationships (newly recognized)	$80 million
Trademarks (newly recognized)	$40 million
Total identifiable assets (A)	$620 million
Debt and other liabilities, including deferred taxes (L)	$260 million
Net identifiable assets (A − L)	$360 million

Goodwill = $500 million − $360 million = $140 million.

The premium over Target’s book net assets was $250 million, but only $140 million became goodwill, because $110 million was traced to fair value step-ups and the two newly recognized intangibles. This affects future earnings: the customer relationships and trademarks (if given finite lives) will be amortized, while the goodwill will not.

When the buyer acquires less than 100%, the calculation also brings in the noncontrolling interest. U.S. GAAP measures the noncontrolling interest at fair value, which produces “full” goodwill. IFRS lets the acquirer choose, deal by deal, between fair value and the noncontrolling interest’s proportionate share of net assets, which can produce a smaller goodwill figure.

Interpreting Goodwill in Accounting

A large goodwill balance tells a reader that the company has grown at least partly through acquisitions and paid premiums over identifiable value. It does not, by itself, say whether those premiums were justified.

Analysts commonly look at:

Goodwill as a share of total assets or equity. A high proportion means much of the balance sheet depends on acquired businesses continuing to perform.
Tangible book value. Equity minus goodwill and other intangibles, which matters to lenders and to investors in asset-heavy or financial companies.
Changes over time. Increases usually trace to new deals. Decreases usually trace to impairments, disposals or currency translation, and the notes to the financial statements explain which.

Goodwill also complicates comparisons. Two companies with similar operations can report very different asset bases and returns on assets if one grew by acquisition and the other grew organically, because only the acquirer carries goodwill.

Impairment: How Goodwill Is Tested and Written Down

Because public-company goodwill is not amortized, it mainly leaves the balance sheet through impairment. Impairment means the carrying amount of the acquired business is now higher than its worth, typically after weaker cash flows, new competition, lost customers, regulatory changes or an economic downturn.

Goodwill is tested at least annually and also whenever a triggering event suggests a loss in value. It is tested at a group level rather than on its own, since it has no standalone value:

U.S. GAAP allocates goodwill to reporting units. A company may first perform a qualitative assessment and skip the quantitative test if it concludes impairment is not more likely than not. Under the simplified approach introduced by ASU 2017-04, the impairment equals the amount by which the reporting unit’s carrying amount exceeds its fair value, capped at the goodwill allocated to that unit.
IFRS (IAS 36) allocates goodwill to cash-generating units. The carrying amount is compared with the recoverable amount, which is the higher of fair value less costs of disposal and value in use. The impairment loss reduces goodwill first, then other assets in the unit.

Fair value or recoverable amount is usually estimated with an income approach (projected cash flows discounted to present value) or a market approach (valuation multiples of comparable companies or transactions in the same industry).

Continuing the hypothetical example. Two years later, the reporting unit holding Target Co. has a carrying amount of $700 million, including the $140 million of goodwill, and a discounted cash flow analysis puts its fair value at $650 million. Under the current U.S. GAAP approach, the impairment is $50 million and goodwill falls to $90 million. Had fair value dropped to $500 million, the charge would be capped at the full $140 million goodwill balance.

An impairment is recorded as a loss on the income statement, reducing net income and earnings per share for that period. It is a non-cash charge, added back when reconciling net income to operating cash flow, so it does not directly change free cash flow. Under both U.S. GAAP and IFRS, it cannot be reversed later, even if the business recovers.

Why Is Goodwill in Accounting Important?

Goodwill links a deal’s price to its later results: it is the part of the premium that has to be earned back through future performance. An impairment formally acknowledges that the expected value has not materialized, which is why large write-downs draw attention from investors and boards.

It also shapes reported profitability. Without amortization, acquisitive public companies avoid a steady annual expense but face large, irregular charges. Measures such as EBITDA are not reduced by amortization of acquired intangibles, and many companies also exclude impairments from adjusted figures, so check what has been added back.

A Brief History of Goodwill Rules

U.S. companies once amortized goodwill over periods of up to 40 years. In 2001, FASB eliminated pooling-of-interests accounting and replaced amortization with impairment testing for public companies, and IFRS followed in 2004 with IFRS 3. Since 2014, private companies under U.S. GAAP may instead amortize goodwill straight-line over up to 10 years (or a shorter justified period) and test for impairment only when a triggering event occurs. FASB considered extending amortization to public companies, partly because impairment testing is costly and depends heavily on estimates, but removed the project from its agenda in 2022.

Limitations of Goodwill in Accounting

It is a residual, not a measurement. Any error in valuing identifiable assets or liabilities flows straight into it.
Impairment tests rely on judgment. Management’s cash flow forecasts, discount rates and comparable-company choices all move the outcome.
Write-downs can lag. Healthy parts of a reporting unit or cash-generating unit can cushion a weak acquisition and delay a charge.
It ignores internally generated value. A strong brand built in-house shows none of it as goodwill.
It has no standalone resale value. If an acquired business fails or the company becomes insolvent, goodwill cannot be sold to repay creditors, which is why lenders and credit analysts often deduct it.

Goodwill vs. other intangible assets. Identifiable intangibles can be separated or arise from contractual or legal rights, are valued individually and are usually amortized. Goodwill is unidentifiable, inseparable and, for public companies, not amortized. Both are assets without physical form.

Goodwill vs. fixed and current assets. Fixed assets usually means property, plant and equipment, which are tangible and depreciated. Current assets are expected to be converted to cash or used up within a year. Goodwill is intangible and held indefinitely, so it is always non-current and is not a fixed asset in that sense.

Goodwill vs. negative goodwill. In a bargain purchase, sometimes after a distressed sale, the fair value of net assets exceeds the price paid. After rechecking that everything was identified and measured correctly, the acquirer recognizes any remaining excess immediately as a gain on the income statement, not as a negative asset.

Accounting goodwill vs. “goodwill” in everyday business. In conversation, goodwill means customer loyalty or a good reputation. In accounting, the term covers only the measured premium from an acquisition.

FAQs

Is goodwill deductible for taxes?

It depends on the jurisdiction and the deal structure. In the U.S., goodwill acquired in an asset purchase can generally be amortized for tax purposes over 15 years under Section 197, even though public companies do not amortize it for financial reporting. In a stock purchase without a special tax election, the buyer typically gets no tax deduction for goodwill.

What happens to goodwill when the acquired business is sold?

The goodwill attributable to the business being disposed of is removed from the balance sheet and included in the carrying amount used to calculate the gain or loss on the sale.

The Bottom Line

Investors, lenders and analysts reading the balance sheet of an acquisitive company need to understand goodwill. A large balance shows that the company paid premiums for acquired businesses, and later performance has to justify those premiums. Impairment charges are non-cash and rest heavily on management estimates. Readers should track how goodwill changes over time, check tangible book value, and look at what adjusted earnings figures add back.
