Example Calculation

A manufacturing company assesses a machine with $100,000 book value for impairment due to technological obsolescence, with $80,000 fair value, $75,000 value in use, $5,000 disposal costs, and 25% tax rate.

Tips

$25,000 Loss Drops to $18,750 After Tax — Always Factor the Tax Shield

At a 25% tax rate, the $25,000 impairment creates a $6,250 tax deduction, reducing the actual net income impact to $18,750. Higher tax rates amplify this benefit — at 30%, the net loss would be $17,500; at 21%, it would be $19,750.

Both Recovery Methods Yield $75,000 Here — But They Often Diverge

Fair value less costs ($80,000 - $5,000 = $75,000) equals value in use ($75,000) in this case. When they differ, IFRS requires using the higher amount. If value in use were $85,000, recoverable amount would be $85,000 and impairment would drop to $15,000.

25% Severity Crosses the 'Significant' Threshold — Disclosure Required

At exactly 25%, this impairment hits the Significant tier (25-50%). Most accounting standards require enhanced disclosure for material impairments, including the events causing it, the cash-generating unit affected, and whether fair value or value in use was used.

To Avoid Impairment, Fair Value Must Exceed $105,000 or Value in Use Must Exceed $100,000

With $5,000 disposal costs, fair value needs to be at least $105,000 for fair value less costs to match the $100,000 carrying amount. Alternatively, value in use alone needs to reach $100,000. Either path eliminates the impairment entirely.

Is Your Asset Worth Less Than Its Book Value?

The Asset Impairment Loss Calculator determines whether an asset's carrying amount exceeds its recoverable amount under IFRS/GAAP standards. With a $100,000 book value, $80,000 fair value, $75,000 value in use, and $5,000 disposal costs, the impairment loss is $25,000 — rated "Significant" at 25.0% of carrying amount. After a $6,250 tax benefit at 25%, the net impact is $18,750.

The Impairment Loss Formula

A comparison between book value and the best recovery path:

Fair Value Less Costs = Fair Value - Disposal Costs
Recoverable Amount = MAX(Fair Value Less Costs, Value in Use)
Impairment Loss = MAX(0, Carrying Amount - Recoverable Amount)
Tax Benefit = Impairment Loss x Tax Rate
Net After-Tax Loss = Impairment Loss - Tax Benefit

Example: Manufacturing Equipment Impairment

$100,000 carrying amount, $80,000 fair value, $75,000 value in use, $5,000 disposal costs, 25% tax rate:

Metric	Value	Context
Fair Value Less Costs	$75,000	$80,000 - $5,000
Value in Use	$75,000	PV of future cash flows
Recoverable Amount	$75,000	Higher of the two (equal here)
Impairment Loss	$25,000	$100,000 - $75,000
Impairment Severity	25.0%	Significant threshold
Tax Benefit	$6,250	$25,000 x 25%
Net After-Tax Loss	$18,750	$25,000 - $6,250
Adjusted Carrying Amount	$75,000	New book value

The $25,000 write-down reduces the asset's balance sheet value by 25%. If the machine were sold at fair value ($80,000), the company would realize a $5,000 gain over the new $75,000 book value — the impairment effectively resets expectations.

Impairment Severity Tiers

The calculator classifies impairment into four levels: Minor (0-10%) for small value drops with limited financial impact, Moderate (10-25%) requiring monitoring and potentially enhanced disclosures, Significant (25-50%) indicating material value erosion requiring management explanation, and Severe (50%+) signaling major issues needing immediate strategic response. This example's 25.0% falls right at the Significant threshold — one dollar less in impairment would classify as Moderate instead.

Frequently Asked Questions

What is asset impairment loss?

When an asset's carrying amount (book value) exceeds its recoverable amount, the difference is an impairment loss. With $100,000 carrying and $75,000 recoverable amount, the $25,000 difference must be written down on the balance sheet and recognized as an expense on the income statement.

What is the recoverable amount?

The higher of fair value less costs to sell and value in use. Fair value less costs = market price minus disposal expenses ($80,000 - $5,000 = $75,000). Value in use = present value of future cash flows ($75,000). The recoverable amount is $75,000 (both equal here).

When should companies test for impairment?

Whenever indicators suggest the carrying amount may not be recoverable — declining market value, technological obsolescence, physical damage, or underperformance. Goodwill and indefinite-life intangibles require annual testing under both IFRS (IAS 36) and US GAAP (ASC 350).

How does the tax benefit work?

Impairment losses are generally tax-deductible, reducing taxable income. A $25,000 write-down at 25% tax rate saves $6,250 in taxes, making the net impact $18,750. The tax benefit is realized when filing the tax return for the period.

Can an impairment loss be reversed?

Under IFRS (IAS 36), impairment losses on most assets can be reversed if conditions improve, up to the original carrying amount minus depreciation that would have been charged. Under US GAAP, reversals are generally prohibited for long-lived assets held for use. Goodwill impairment reversals are prohibited under both frameworks.

What is the difference between impairment and depreciation?

Depreciation systematically allocates cost over useful life (e.g., $10,000/year for 10 years). Impairment is an immediate, one-time write-down when economic value drops below book value. A fully depreciated asset cannot be impaired, but a partially depreciated asset can — this $25,000 impairment occurs separately from regular depreciation.
