Unpacking Depreciation: Your Essential Guide to Asset Value Over Time

🔍 Introduction:

Imagine you own a bustling toy shop, filled with the latest gadgets, games, and cuddly creatures. Every year, you buy new toys to keep up with trends, but what happens to the toys that have been on the shelves for a while? Maybe some get a bit dusty, a few show signs of being handled, or perhaps a new, shinier version comes out. Even if you haven't sold them, their value to your shop isn't quite the same as when they were brand new. You wouldn't expect to sell a well-loved display model for the same price as a sealed, untouched one, right?

In the world of accounting, businesses face a similar reality with their long-term possessions, like delivery vans, shop fittings, or even the building itself. These aren't items they plan to sell quickly; they're used to help the business operate and make money. Over time, these valuable items, known as fixed assets, gradually lose some of their original usefulness or value. This isn't just about what you could sell them for today; it's about how much of their value has been "used up" in helping your business run. This "using up" of value is what we call depreciation, and understanding it is crucial for knowing the true financial health and performance of any business. It helps ensure that the financial statements show a true and fair view of the business's situation.

🧱 Core Concepts:

🪙 What Exactly is a Fixed Asset?

Before we dive deeper into depreciation, let's clarify what a fixed asset is. Fixed assets are tangible items (things you can touch) that a business owns, are expected to have a long life, are used in the business to generate income, and are not bought with the main purpose of being resold quickly.

• Examples include buildings, machinery, motor vehicles, and fixtures.
• The source explicitly notes that you need to be sure you know what a fixed asset is before looking at depreciation.

📉 Defining Depreciation: The "Used Up" Value

At its core, depreciation is the portion of a fixed asset's original cost that is consumed during its period of use by the business. Think of it as the cost of using the asset over time. It's an estimate of how much of the asset's overall economic usefulness has been used up in a particular accounting period.

📊 The Logic Behind Providing for Depreciation

Why do businesses go through the trouble of calculating and recording depreciation? There are several compelling reasons:

• True and Fair View: Financial statements must present a true and fair view of a business's financial performance and position. If depreciation wasn't accounted for, both the value of fixed assets on the balance sheet and the reported profits would be inflated, which would mislead anyone looking at the financial statements.
• Matching Principle (Accruals Concept): The accruals concept states that profit is the difference between revenues and the expenses incurred to generate those revenues. Fixed assets help generate revenue over multiple years, so their cost should be spread across those years, matching the expense to the revenue it helps create.
• Regulatory Requirement: Accounting standards, such as IAS 16, explicitly requires that fixed assets be depreciated.
• Cost Allocation, Not Fund Setting: It's important to understand that providing for depreciation is a bookkeeping entry and a method of allocating cost over time. It does not mean that money is physically set aside in a separate fund to replace the asset. This is a common misunderstanding, especially among those new to accounting. While a cautious owner might take less out in drawings if profits are lower due to depreciation, this doesn't mean funds are automatically available for replacement.

🔧 What Causes Assets to Depreciate?

Several factors contribute to the reduction in a tangible fixed asset's value:

• Physical Deterioration:
  • Wear and Tear: Regular use causes assets like motor vehicles, machinery, or even buildings to gradually wear out.
  • Rust, Rot, Decay: Exposure to elements or natural processes can lead to assets deteriorating even when not actively used.
• Economic Factors:
  • Obsolescence: An asset can become outdated or less useful due to technological advancements (e.g., an old computer model) or changes in demand for the product it produces, even if it's still physically sound.
  • Inadequacy: As a business grows, an asset that was once sufficient might become too small or slow to meet new demands (e.g., a small delivery van for a rapidly expanding business).
• Time:
  • Some assets lose value simply because time passes, regardless of use. A lease on a building, for example, decreases in value as it approaches its expiry date. This is sometimes referred to as amortisation.
• Depletion:
  • This applies to wasting assets like mines or quarries, where the asset is literally consumed as its natural resources are extracted.

⛽ Depreciation as an Expense: A Van and Its Fuel

Think of a delivery van used by a business.

• The petrol it consumes is an expense that is used up almost immediately, perhaps in a day or two.
• The van itself is also an expense because its value is consumed as it's used for deliveries. The difference is that the van's usefulness is spread over several years.

Both the petrol and the cost of the van are legitimate business expenses, but they are accounted for differently due to their useful life. Depreciation is recorded as an expense to the profit and loss account, which then reduces the reported net profit.

🧮 Methods of Calculating Depreciation Charges

While there are various ways to calculate depreciation, the two most common methods are the straight line method and the reducing balance method. Most accountants often consider the straight line method to be generally more suitable.

➖ The Straight Line Method

This method charges the same amount of depreciation to the profit and loss account each year throughout the asset's estimated useful life. It's straightforward and easy to understand.

• Definition: Deducting the same amount every accounting period from the original cost of the fixed asset.
• Logic/Use: This method is most appropriate when the economic benefits derived from the asset are expected to be gained evenly over its useful life.
• Calculation: The annual depreciation charge is calculated using this formula: (Cost of Asset - Estimated Disposal/Scrap Value) / Number of Expected Years of Use

📐 Mini Case Study/Example (Straight Line):

• A lorry was bought for $22,000.
• It is expected to be kept for four years.
• Its estimated selling price (disposal value) at the end of four years is $2,000.

Using the formula:
($22,000 - $2,000) / 4 years = $20,000 / 4 years = $5,000 per year

So, $5,000 would be charged as depreciation each year for four years.

Actionable Step: If your asset provides a consistent level of service or benefit throughout its life, the straight line method offers a clear and predictable way to allocate its cost.

📉 The Reducing Balance Method

This method charges a higher amount of depreciation in the early years of an asset's life and a lower amount in later years. This is because the depreciation is calculated as a fixed percentage of the asset's remaining book value (cost less accumulated depreciation) each year.

• Definition: A method of calculating depreciation based on the principle that you calculate annual depreciation as a percentage of the net-of-depreciation-to-date balance (book value) brought forward at the start of the period on the fixed asset.
• Logic/Use:
  • This method is suitable for assets that lose a greater proportion of their value in their early years, such as motor vehicles, or for assets that are more productive initially.
  • Advocates argue it helps to "even out" the total expense of using the asset each year. In the early years, depreciation is high, but repairs and maintenance might be low. In later years, depreciation is lower, but repairs and maintenance often increase with age.
• Calculation: A fixed percentage rate is applied to the net book value (cost minus accumulated depreciation) of the asset at the beginning of each year.

📊 Mini Case Study/Example (Reducing Balance):

• A machine is bought for $10,000.
• Depreciation is charged at a rate of 20 per cent using the reducing balance method.

Calculations for the first three years:

• Year 1:
  • Cost: $10,000
  • Depreciation (20% of $10,000): $2,000
  • Remaining Book Value (end of Year 1): $8,000
• Year 2:
  • Depreciation (20% of $8,000): $1,600
  • Remaining Book Value (end of Year 2): $6,400
• Year 3:
  • Depreciation (20% of $6,400): $1,280
  • Remaining Book Value (end of Year 3): $5,120

Actionable Step: Consider using this method for assets that decline rapidly in value or have higher maintenance costs as they age. The source states the percentage for this method is usually 2 to 3 times greater than the straight line method.

📅 Depreciation on Assets Acquired or Disposed of Mid-Year

When assets are bought or sold partway through an accounting period, there are two common approaches to calculating depreciation for that specific year:

• Method 1: Full Year in Purchase Year, None in Sale Year (or vice versa): This approach provides a full year's depreciation in the year the asset is purchased and no depreciation in the year it is sold (or the reverse). This method is normally used in practice if no specific dates are given.
• Method 2: Proportionate Basis: Depreciation is charged for the specific number of months the asset was owned during the accounting period (e.g., "one month's ownership = one month's provision for depreciation"). Fractions of months are usually ignored. This is a more precise method and is often expected in examinations when dates are provided.

Actionable Step: For examination purposes, if dates are provided, use the proportionate basis (Method 2). If no dates are given, use Method 1 but clearly state your assumption.

📝 Recording Depreciation: The Modern Approach

The old method of directly reducing the asset account for depreciation is now largely out of use because it made it hard to see the original cost of the asset. The modern method keeps the original cost visible.

🔢 The One-Stage Method (Most Common in Practice)

This method uses two accounts to record depreciation:

1. Profit and Loss Account (Debit): The depreciation expense for the period is debited here, reducing the profit for the year.
2. Accumulated Provision for Depreciation Account (Credit): This account accumulates the total depreciation charged on the asset from the date of purchase to the present. It is sometimes confusingly referred to as the 'provision for depreciation account'.

The asset account itself remains at its original cost price. On the balance sheet, the accumulated depreciation is shown as a deduction from the asset's cost to arrive at its net book value.

💻 Mini Case Study/Example (One-Stage Method):

A business has a financial year-end of 31 December. A computer is bought for $2,000 on 1 January 20X5 and depreciated at 20% using the reducing balance method.

Profit and Loss Account (Extracts for Expense):

• 20X5: Provision for depreciation: Computer ($400)
• 20X6: Provision for depreciation: Computer ($320)
• 20X7: Provision for depreciation: Computer ($256)

Accumulated Provision for Depreciation Account:

• 20X5 Dec 31: Profit and Loss $400 (Balance c/d $400)
• 20X6 Jan 1: Balance b/d $400; Dec 31: Profit and Loss $320 (Balance c/d $720)
• 20X7 Jan 1: Balance b/d $720; Dec 31: Profit and Loss $256 (Balance c/d $976)

Balance Sheet (Extracts):

• As at 31 December 20X5:
  • Computer at cost: $2,000
  • Less Accumulated depreciation: ($400)
  • Net Book Value: $1,600
• As at 31 December 20X6:
  • Computer at cost: $2,000
  • Less Accumulated depreciation: ($720)
  • Net Book Value: $1,280
• As at 31 December 20X7:
  • Computer at cost: $2,000
  • Less Accumulated depreciation: ($976)
  • Net Book Value: $1,024

🔄 The Two-Stage Method (Theoretical, sometimes used in exams)

This method involves two double entries for each period's depreciation:

1. Debit the Depreciation Account; Credit the Accumulated Provision for Depreciation Account.
2. Debit the Profit and Loss Account; Credit the Depreciation Account.

This approach makes the depreciation expense explicit in a separate account before transferring it to the Profit and Loss Account. However, the net effect is the same as the one-stage method, as the debit and credit to the 'Depreciation Account' cancel out.

Actionable Step: Unless specifically asked by an examiner for the two-stage method, assume and use the one-stage method for simplicity and common practice.

💰 Disposal of Fixed Assets: What Happens When an Asset is Sold?

When a fixed asset is sold, its cost and its accumulated depreciation need to be removed from the books, and any profit or loss on the sale must be calculated and recorded.

📋 Accounting Entries for Disposal:

1. Transfer the cost of the asset to an Assets Disposal Account:
   • Debit the Assets Disposal Account (e.g., "Computer Disposals Account").
   • Credit the Asset Account (e.g., "Computer Account").
2. Transfer the accumulated depreciation for the sold asset to the Assets Disposal Account:
   • Debit the Accumulated Provision for Depreciation Account.
   • Credit the Assets Disposal Account.
3. Record the cash/bank received from the sale:
   • Debit the Cash/Bank Account.
   • Credit the Assets Disposal Account.
4. Transfer the profit or loss on disposal to the Profit and Loss Account:
   • If it's a loss, Debit the Profit and Loss Account; Credit the Assets Disposal Account.
   • If it's a profit, Credit the Profit and Loss Account; Debit the Assets Disposal Account.

Why Estimates are Rarely Perfect: When an asset is disposed of, the actual amount received is usually different from the original estimate of its residual value. This leads to a profit or loss on disposal. Factors causing inaccuracies include uncertainty about how long an asset will be used, its future selling price, or even if it can be sold at all.

Actionable Step: Always remember that the profit or loss on disposal reflects the difference between the asset's net book value (cost less accumulated depreciation) and its actual selling price.

✅ Quick Recap:

• Depreciation is the portion of a fixed asset's cost consumed during its useful life, recorded as an expense.
• It ensures financial statements show a true and fair view by not overstating assets or profits.
• Causes include physical wear, economic obsolescence, time, and depletion.
• It's a non-cash expense, meaning no actual cash is set aside.
• Straight Line Method charges the same amount annually, suitable for assets with even benefit distribution.
• Reducing Balance Method charges more in early years, suitable for assets that lose value or are more productive upfront.
• Depreciation is usually recorded by crediting an Accumulated Provision for Depreciation Account and debiting the Profit and Loss Account.
• Upon disposal, the asset's cost and accumulated depreciation are transferred to an Assets Disposal Account to calculate profit or loss on sale.

❓ FAQs:

What is a fixed asset?

Fixed assets are tangible items of material value that a business owns, has for a long life, uses in the business, and does not intend to resell in the short term, such as buildings, machinery, and motor vehicles.

What is depreciation?

Depreciation is the part of the original cost of a fixed asset that is consumed during its period of use by the business. It is an estimate of how much of the asset's economic usefulness has been used up in an accounting period.

Why do businesses provide for depreciation?

Businesses provide for depreciation to ensure their financial statements show a true and fair view of their financial performance and position. Without it, fixed assets and profits would be overstated, potentially misleading users. It also helps to match the cost of the asset with the revenues it helps generate over its useful life.

Is depreciation a cash expense?

No, depreciation is a non-cash expense. It is a bookkeeping entry that allocates the cost of an asset over its useful life and reduces net profit, but it does not involve an actual outflow of cash during the period it is recorded.

What are the main causes of depreciation?

The main causes of depreciation are physical deterioration (wear and tear, rust, decay), economic factors (obsolescence, inadequacy), the passage of time (e.g., leases), and depletion (for wasting assets like mines).

What is the straight line method of depreciation?

The straight line method is a depreciation method that deducts the same amount from the original cost of a fixed asset in every accounting period throughout its estimated useful life.

How is straight line depreciation calculated?

It is calculated as: (Cost of Asset - Estimated Disposal/Scrap Value) / Number of Expected Years of Use.

What is the reducing balance method of depreciation?

The reducing balance method is a depreciation method that calculates annual depreciation as a fixed percentage of the asset's net book value (cost less accumulated depreciation) at the beginning of each period, resulting in higher charges in early years.

How is reducing balance depreciation calculated?

A fixed percentage rate is applied to the carrying amount (book value) of the asset each year. For example, a 20% rate on a $10,000 asset would be $2,000 in Year 1, then $1,600 (20% of $8,000) in Year 2, and so on.

Which depreciation method is generally considered most suitable?

Most accountants think that the straight line method is generally most suitable.

When is the straight line method most appropriate?

The straight line method is most appropriate when the economic benefits or usefulness of an asset are expected to be gained evenly over its years of use.

When is the reducing balance method most appropriate?

The reducing balance method is most appropriate when the main value or benefits from an asset are obtained in its earliest years, or when assets decline more rapidly in value initially. It can also help to even out total usage costs (depreciation plus repairs) over time.

How is depreciation recorded in the accounting books (modern method)?

Using the modern one-stage method, depreciation is recorded by debiting the profit and loss account and crediting the accumulated provision for depreciation account. The asset account itself remains at cost.

What is an accumulated provision for depreciation account?

This is an account that accumulates the total depreciation charged on a fixed asset from its date of purchase. It is used to keep the asset's original cost visible in the asset account.

What happens to the fixed asset account when depreciation is charged?

Under modern methods, the fixed asset account is kept at its original cost price. The depreciation is credited to a separate accumulated provision for depreciation account, not directly to the asset account.

What happens when a fixed asset is sold?

When a fixed asset is sold, its original cost and its accumulated depreciation are transferred to a separate assets disposal account. Any cash received is also recorded in this account, and finally, any profit or loss on the sale is transferred to the profit and loss account.

How is profit or loss on the disposal of a fixed asset treated?

A profit on disposal is transferred to the credit of the profit and loss account, increasing net profit. A loss on disposal is transferred to the debit of the profit and loss account, decreasing net profit.

Why are depreciation calculations considered estimates?

Depreciation calculations are estimates because it is difficult to accurately predict an asset's useful life, its exact residual value, and how its "use" will be measured over many years. Actual outcomes often differ from initial estimates.

Does depreciation fund the replacement of assets?

No, making a provision for depreciation does not mean money is invested or set aside to finance the replacement of the asset. It is merely a bookkeeping entry to spread the cost over time; any funds for replacement would need to be actively saved or sourced elsewhere.

What happens if depreciation is omitted from financial statements?

If depreciation is omitted, both the fixed assets and the reported profits in the financial statements would be overstated, presenting a misleading picture of the business's financial performance and position.

What is the 'book value' or 'net book value' of an asset?

The book value or net book value of an asset is its original cost less its accumulated depreciation to date.

What is 'residual value' or 'scrap value'?

The residual value (or scrap value) is the estimated amount expected to be received when a fixed asset is disposed of at the end of its useful life to the business.

How does depreciation appear on the balance sheet?

On the balance sheet, fixed assets are typically shown at their original cost, followed by a deduction for the total accumulated depreciation to date, resulting in the net book value of the asset.

What is the prudence concept and how does it relate to depreciation?

The prudence concept (also known as conservatism) requires ensuring that assets are not valued too highly and profits are not overstated. In the context of depreciation, it supports making an allowance for the reduction in asset value even if the exact amount is an estimate, rather than overstating the asset's worth.

How is depreciation handled for assets bought or sold mid-year in examinations?

If specific dates are given in an examination question, you should usually calculate depreciation on a proportionate basis (e.g., one month's depreciation for one month's ownership), ignoring fractions of months. If no dates are given, you should assume a full year's depreciation in the year of purchase and none in the year of sale (or vice versa), stating your assumption.
