Fixed assets form the structural foundation of every successful business, representing long-term investments that support production, operations, and service delivery. However, as time passes, these assets inevitably lose value through wear, technological changes, or reduced economic usefulness. To capture this decline accurately, accountants apply the principle of depreciation — a method that systematically allocates the asset’s cost over its useful life. This approach ensures that financial statements reflect true economic value and promote sustainable capital management. In this article, we will explore the nature of fixed assets, the mechanics of depreciation, the accounting process, and real-world examples that illustrate how both concepts contribute to business longevity.
1. What Are Fixed Assets?
Definition
Fixed assets, also known as non-current assets, are resources acquired for long-term use in operations rather than for immediate resale. They provide economic benefits to an organization over multiple accounting periods and typically have a useful life exceeding one year. According to IAS 16 (Property, Plant and Equipment) and IAS 38 (Intangible Assets), fixed assets are recognized when it is probable that future benefits will flow to the business and the cost of the asset can be measured reliably.
Examples of Fixed Assets
- Land: Considered a permanent asset that often appreciates in value. It is not depreciated under accounting standards but may be subject to revaluation.
- Buildings: Structures such as offices, factories, and warehouses that support operations and production processes.
- Machinery and Equipment: Tools and production equipment used in manufacturing or service delivery.
- Vehicles: Transport assets, including company cars, vans, and delivery trucks.
- Intangible Assets: Non-physical resources such as patents, trademarks, goodwill, and software licenses.
Fixed assets appear under the “Non-Current Assets” section of the balance sheet and are often referred to as Property, Plant, and Equipment (PPE). Their presence signals long-term investment and operational strength.
2. What Is Depreciation?
Definition
Depreciation is the accounting process of allocating the cost of a tangible fixed asset over its useful life. It acknowledges that assets decline in value as they are used or become obsolete. The goal is not to determine market value but to match the expense of using the asset to the revenue it helps generate. This process is fundamental to the matching principle in accounting, ensuring that income and related expenses are recognized in the same period.
Purpose of Depreciation
- Reflect Accurate Value: Keeps the balance sheet realistic by recording assets at their declining book values rather than historical cost.
- Expense Allocation: Ensures that each financial period bears a fair share of the asset’s cost relative to its contribution to revenue.
- Compliance: Aligns with international accounting standards such as IFRS and GAAP for transparent and consistent financial reporting.
- Tax Planning: Allows businesses to deduct depreciation as a non-cash expense, reducing taxable income legally.
For example, a delivery truck loses value each year due to use and aging. Depreciation ensures this decline is reflected gradually, providing an accurate view of profitability and financial position.
3. Methods of Depreciation
Depreciation can be calculated using several methods, depending on the nature of the asset and its usage pattern. The method chosen should best represent how the asset’s economic benefits are consumed over time.
A. Straight-Line Method
The most common and simplest method, the straight-line method spreads the asset’s cost evenly across its useful life.
Formula: (Cost of Asset – Residual Value) ÷ Useful Life
Example: A machine purchased for $50,000 with an estimated residual value of $5,000 and a useful life of 10 years would have an annual depreciation of:
($50,000 – $5,000) ÷ 10 = $4,500 per year.
This approach is often used for buildings, office equipment, and furniture where the asset provides consistent benefits over time.
B. Reducing Balance Method
This method applies a fixed depreciation rate to the asset’s book value, producing higher expenses in early years and lower ones later. It recognizes that many assets are more productive in their early years.
Example: A delivery vehicle costing $30,000 with a 20% depreciation rate will have:
- Year 1: $30,000 × 20% = $6,000
- Year 2: ($30,000 – $6,000) × 20% = $4,800
- Year 3: ($24,000 – $4,800) × 20% = $3,840
This declining pattern better mirrors the reality of assets that experience heavy use in initial years.
C. Units of Production Method
The units of production method ties depreciation directly to the asset’s activity level or output. This approach is ideal for manufacturing machinery or vehicles whose wear depends on use rather than time.
Formula: (Cost – Residual Value) × (Units Used ÷ Total Estimated Units)
For instance, if a machine expected to produce 100,000 units costs $120,000 with a residual value of $20,000, and it produces 10,000 units in a year, annual depreciation is:
($120,000 – $20,000) × (10,000 ÷ 100,000) = $10,000.
This method provides precision in cost allocation when asset usage fluctuates significantly.
4. Accounting for Fixed Assets and Depreciation
A. Initial Recording
When acquired, fixed assets are recorded at historical cost — the purchase price plus any directly attributable expenses necessary to prepare the asset for use. Examples include shipping, installation, testing, and professional fees. Under IFRS, component accounting may apply if significant parts of the asset have different useful lives.
B. Depreciation Expense
Depreciation is recognized as an expense on the income statement, reducing reported profits. On the balance sheet, accumulated depreciation (a contra-asset account) increases each period, reducing the asset’s net book value.
Example journal entries:
- Debit: Depreciation Expense
- Credit: Accumulated Depreciation
This ensures both financial statements reflect the cost allocation accurately.
C. Book Value
The book value (or carrying amount) of a fixed asset equals its original cost minus accumulated depreciation. This represents the asset’s net worth at a particular date. Book value typically differs from market value due to accounting policies and external factors such as inflation or technological change.
D. Disposal of Fixed Assets
When a fixed asset is sold, scrapped, or retired, it must be derecognized from the books. The difference between the sale proceeds and book value determines whether there is a gain or loss. The transaction is reported on the income statement.
Example: Equipment with a book value of $20,000 sold for $25,000 yields a gain of $5,000. Conversely, if sold for $18,000, it results in a $2,000 loss.
5. Practical Examples
Example 1: Depreciation of Machinery
A factory purchases a production machine for $100,000, with an expected residual value of $10,000 and a 10-year useful life. Using the straight-line method:
($100,000 – $10,000) ÷ 10 = $9,000 annual depreciation.
- Expense: $9,000 is recorded yearly as depreciation expense.
- Accumulated Depreciation: Increases annually by $9,000, reducing the machine’s book value.
Example 2: Depreciation of a Vehicle
A logistics company purchases a truck for $40,000, applying a 25% reducing balance rate:
- Year 1: $40,000 × 25% = $10,000
- Year 2: ($40,000 – $10,000) × 25% = $7,500
- Year 3: ($30,000 – $7,500) × 25% = $5,625
In this case, higher depreciation in early years aligns with the asset’s heavier use during its initial period.
Example 3: Disposal of Fixed Assets
A business sells a piece of equipment with a book value of $20,000 for $25,000. The gain of $5,000 is recognized as income. This example demonstrates how disposal affects both profit and asset turnover efficiency.
6. Importance of Depreciating Fixed Assets
A. Accurate Financial Reporting
Depreciation aligns book values with economic reality. Without it, businesses would overstate asset values and profitability. For instance, a company that ignores depreciation on a $2 million plant would falsely inflate its income and mislead stakeholders.
B. Expense Matching
By spreading an asset’s cost over its useful life, depreciation ensures expenses are recognized in the same periods as the revenues generated by those assets. This creates fair performance comparisons across periods and prevents distortion of profits.
C. Decision-Making
Accurate depreciation data assists management in making investment and replacement decisions. Knowing the remaining book value of key equipment helps prioritize capital expenditures and plan upgrades efficiently.
D. Compliance
Adhering to IFRS and GAAP standards ensures transparency and comparability across industries. Investors and auditors rely on depreciation practices to assess management integrity and asset management efficiency.
E. Tax Efficiency
In many jurisdictions, depreciation is an allowable tax deduction. Strategic depreciation planning can therefore optimize cash flow while remaining compliant with legal requirements.
7. Challenges in Depreciating Fixed Assets
A. Estimating Useful Life
Determining an asset’s lifespan requires judgment based on historical performance, technological evolution, and industry standards. An incorrect estimate can distort depreciation charges and profitability metrics. For example, machinery with an assumed 15-year life that becomes obsolete in 8 years creates misaligned expense recognition.
B. Choosing a Depreciation Method
Selecting the most appropriate method depends on the asset’s nature and use. A high-tech company may favor accelerated depreciation to reflect rapid innovation cycles, while a construction firm might choose straight-line depreciation for consistent long-term assets like cranes and bulldozers.
C. Residual Value
Estimating residual value — the expected salvage value at the end of the asset’s life — involves uncertainty. Economic shifts, market demand, and technological progress can drastically alter resale values. Businesses should periodically reassess estimates to remain accurate.
D. Impairment and Revaluation
Under IAS 36 (Impairment of Assets), companies must test whether assets have suffered a loss in recoverable value. If the carrying amount exceeds the recoverable amount, an impairment loss must be recognized, reducing both asset value and profit. Conversely, under IFRS, revaluation can increase an asset’s carrying amount if market value rises, though gains are recorded in other comprehensive income.
Sustaining Long-Term Value
Fixed assets and depreciation are two sides of the same financial coin — one represents long-term investment, and the other ensures responsible recognition of its consumption. Together, they enable accurate financial statements, better management decisions, and sustained operational efficiency. A company that actively manages its fixed assets through regular maintenance, fair valuation, and appropriate depreciation methods not only ensures compliance but also preserves shareholder trust and financial integrity.
Ultimately, depreciation is more than an accounting adjustment — it is a reflection of time, technology, and stewardship. Businesses that understand and manage this relationship effectively sustain their long-term value, laying the groundwork for stability, transparency, and growth in an ever-evolving economic environment.
