Journal Entries for Depreciation and Impairment of Fixed Assets

When a business invests in equipment, machinery, vehicles, or buildings, these assets don't maintain their value indefinitely. They wear down, become outdated, or suffer physical damage. As an accountant, CFO, or small business owner, understanding how to properly record the decline in value of fixed assets through depreciation and impairment is essential for maintaining accurate financial statements, tax compliance, and informed business decisions.

This guide walks you through the complete process of recording journal entries for depreciation and impairment of fixed assets, with practical examples and step-by-step instructions you can apply immediately in your accounting workflow.

Understanding Fixed Asset Depreciation

What Is Depreciation?

Depreciation is the systematic allocation of the cost of a tangible fixed asset over its useful life. It represents the portion of an asset's value that has been consumed during a specific accounting period. Unlike a simple expense, depreciation spreads the cost of a significant capital purchase across multiple periods, matching expenses with the revenues those assets help generate.

Under Generally Accepted Accounting Principles (GAAP) and International Financial Reporting Standards (IFRS), companies must depreciate their fixed assets to present a true and fair view of their financial position.

Common Depreciation Methods

Businesses typically choose from three primary depreciation methods, each offering different advantages depending on the nature of the asset and the company's financial strategy.

Straight-Line Depreciation distributes cost evenly across an asset's useful life. This method works well for assets that provide consistent benefits over time, such as office furniture or buildings.

Declining Balance Depreciation applies a fixed percentage to the asset's declining book value each year, resulting in higher depreciation expenses early in an asset's life. This approach suits assets that lose value quickly or generate greater benefits initially, like technology equipment or vehicles.

Units of Production Depreciation ties depreciation to actual usage rather than time. An asset that operates more intensively in certain years will bear higher depreciation during those periods, making this method ideal for manufacturing equipment or delivery vehicles.

Recording Depreciation: The Basic Journal Entry

The standard journal entry for depreciation debits a depreciation expense account and credits an accumulated depreciation contra-asset account. This approach maintains the original cost of the asset on the balance sheet while separately tracking its cumulative depreciation.

The journal entry template follows this structure:

Debit: Depreciation Expense (Income Statement)
Credit: Accumulated Depreciation (Balance Sheet - Contra Asset)

The depreciation expense appears on the income statement, reducing net income. The accumulated depreciation account reduces the asset's book value on the balance sheet without eliminating the asset record entirely.

Depreciation Methods and Calculations

Straight-Line Depreciation Example

Consider a company that purchases delivery equipment for $50,000 with the following characteristics:

Cost: $50,000
Estimated residual value: $5,000
Useful life: 5 years

Annual Depreciation Calculation:

(Cost - Residual Value) ÷ Useful Life
($50,000 - $5,000) ÷ 5 = $9,000 per year

Monthly Journal Entry:

Date          Account                    Debit      Credit
─────────────────────────────────────────────────────────
Dec 31        Depreciation Expense       $9,000    
              Accumulated Depreciation              $9,000
              (Straight-line depreciation)

At year-end, the balance sheet would show:

Delivery Equipment: $50,000 (original cost)
Less: Accumulated Depreciation: $9,000
Book Value: $41,000

Declining Balance Depreciation Example

Using the same $50,000 equipment with a 5-year useful life and $5,000 residual value, assume the company uses double-declining balance depreciation (200% ÷ 5 years = 40% rate).

Year 1 Calculation:

Book Value × Declining Balance Rate
$50,000 × 40% = $20,000

Year 2 Calculation:

($50,000 - $20,000) × 40% = $12,000

Year 3 Calculation:

($50,000 - $32,000) × 40% = $7,200

The depreciation amount decreases each year. In the final years, the company must ensure the asset's book value doesn't fall below its residual value.

Units of Production Depreciation Example

If the delivery equipment is expected to operate for 100,000 total miles over its useful life, and it travels 22,000 miles in Year 1:

Depreciation Per Mile:

($50,000 - $5,000) ÷ 100,000 miles = $0.45 per mile

Year 1 Depreciation:

22,000 miles × $0.45 = $9,900

This method directly ties depreciation to actual asset usage, providing the most accurate matching of expense to benefit when usage varies significantly between periods.

Understanding Asset Impairment

What Triggers Impairment?

While depreciation accounts for normal wear and tear over an asset's expected useful life, impairment addresses unexpected, sudden reductions in an asset's value. An asset becomes impaired when its recoverable amount falls below its carrying amount (book value).

Several events can trigger impairment testing:

Physical damage from accidents, natural disasters, or wear beyond expectations
Technological obsolescence making the asset significantly less useful than originally anticipated
Market conditions such as economic downturns reducing demand for products the asset produces
Regulatory changes rendering the asset non-compliant or less valuable
Management decisions to discontinue or significantly restructure operations using the asset

Recognizing Impairment Loss

Under GAAP (ASC 360) and IFRS (IAS 36), impairment loss equals the amount by which an asset's carrying amount exceeds its fair value. Companies must test for impairment when evidence suggests an asset may be impaired—there's no requirement to test all assets annually unless they're subject to impairment testing rules.

The impairment loss calculation follows this formula:

Impairment Loss = Carrying Amount - Recoverable Amount

Recoverable amount is the higher of:

Fair value minus costs to sell
Value in use (present value of future cash flows expected from the asset)

Journal Entries for Impairment

Impairment Journal Entry Example

Assume a manufacturing company owns specialized machinery with the following values:

Original cost: $200,000
Accumulated depreciation: $80,000
Carrying amount (book value): $120,000
Fair value (less selling costs): $85,000
Value in use: $90,000
Recoverable amount: $90,000 (higher of $85,000 and $90,000)

Impairment Loss Calculation:

$120,000 - $90,000 = $30,000

Journal Entry:

Date          Account                    Debit      Credit
─────────────────────────────────────────────────────────
Dec 31        Impairment Loss            $30,000   
              Accumulated Depreciation              $30,000
              (Impairment of machinery)

The impairment loss of $30,000 appears on the income statement as a separate line item, reducing operating income. After recording impairment, the machinery's new book value becomes:

Original cost: $200,000
Accumulated depreciation: $80,000
Accumulated impairment: $30,000
New carrying amount: $90,000

Important Considerations for Impairment

Under IFRS, if circumstances change and an impaired asset recovers some value, companies may reverse impairment losses (except for goodwill). Under US GAAP, reversals of impairment losses are generally prohibited—once impaired, the asset's cost basis remains permanently reduced.

Depreciation vs. Impairment: Key Differences

Aspect	Depreciation	Impairment
Nature	Systematic, predictable allocation	Unpredictable, event-driven reduction
Frequency	Recorded regularly (monthly/annually)	Tested when triggering events occur
Calculation	Based on cost, residual value, and useful life	Based on recoverable amount vs. carrying amount
Reversibility	Not reversed (though estimates can change)	Generally not reversible under US GAAP; may reverse under IFRS
Purpose	Matches asset cost to periods of benefit	Reflects sudden loss in value beyond normal wear
Trigger	Time or usage passage	Specific events indicating value decline
Financial Impact	Reduces asset book value gradually	Can cause significant, sudden expense recognition

Practical Example: Complete Asset Lifecycle

Consider a company that purchases production equipment with the following profile:

Asset Details:

Purchase date: January 1, Year 1
Cost: $100,000
Residual value: $10,000
Useful life: 8 years
Depreciation method: Straight-line

Year 1-3: Normal Depreciation

Annual depreciation: ($100,000 - $10,000) ÷ 8 = $11,250 per year

After 3 years:

Accumulated depreciation: $33,750
Book value: $66,250

Year 3: Impairment Event

During Year 3, a competitor releases superior technology, significantly reducing the equipment's market value. Testing reveals:

Fair value less costs to sell: $45,000
Value in use: $48,000
Recoverable amount: $48,000
Carrying amount before impairment: $66,250

Impairment loss: $66,250 - $48,000 = $18,250

Journal Entry:

Date          Account                    Debit      Credit
─────────────────────────────────────────────────────────
Dec 31        Impairment Loss            $18,250   
              Accumulated Depreciation              $18,250
              (Impairment of production equipment)

After impairment:

Book value: $48,000
Remaining depreciable base: $48,000 - $10,000 = $38,000
Remaining useful life: 5 years

Year 4-8: Revised Depreciation

New annual depreciation: $38,000 ÷ 5 = $7,600 per year

The company continues depreciating the asset over its remaining useful life at the reduced amount.

Bottom Line

Recording proper journal entries for depreciation and impairment of fixed assets ensures your financial statements accurately reflect the true value and condition of your business investments. Depreciation systematically spreads asset costs across their useful lives, while impairment captures unexpected losses that depreciation alone cannot address.

Key takeaways to implement immediately:

Choose depreciation methods that match your asset usage patterns and be consistent in their application
Document impairment testing thoroughly whenever triggering events occur, as auditors and regulators will examine these decisions
Maintain clear supporting schedules showing original cost, accumulated depreciation, and any impairment charges for every fixed asset
Review asset values regularly to ensure book values don't exceed recoverable amounts
Train your team on the difference between depreciation (expected, systematic) and impairment (unexpected, event-driven) to ensure correct classification

Accurate depreciation and impairment accounting protects your stakeholders, supports informed asset management decisions, and keeps your financial records compliant with current accounting standards. When in doubt, consult with a certified accountant to review your fixed asset policies and ensure your journal entries meet professional requirements.
