Depreciation: Process, Bases & Methods for CA Foundation Accounting

Depreciation is a fundamental concept in accounting, representing the systematic allocation of the cost of a tangible asset over its useful life. For CA Foundation students, a solid understanding of depreciation – its meaning, causes, methods, and accounting treatment – is crucial for mastering financial statements and preparing for higher levels of the CA curriculum.

In India, depreciation is governed by Schedule II of the Companies Act, 2013 for companies, and Accounting Standard 10 (AS 10) / Indian Accounting Standard 16 (Ind-AS 16) for financial reporting. While the Income Tax Act, 1961, also deals with depreciation, its rules are primarily for tax computation and differ from financial accounting.

Quick Answer for Featured Snippets:
Depreciation is the systematic allocation of an asset's depreciable amount (Cost - Residual Value) over its useful life. It's not a cash expense but an accounting adjustment to match the cost of using an asset with the revenue it helps generate. The two main methods are Straight Line Method (SLM) and Written Down Value (WDV).

What is Depreciation? Definition, Causes & Importance

Depreciation, as per accounting standards like AS 10 (Property, Plant and Equipment) and Schedule II of the Companies Act, 2013, is defined as:

"Depreciation is the systematic allocation of the depreciable amount of an asset over its useful life."

Let's break down the key terms:

• Depreciable amount: This is the cost of an asset less its estimated residual (or salvage) value.
• Useful life: This refers to the period over which an asset is expected to be available for use by an entity, or the number of production units expected to be obtained from the asset.

Main Causes of Depreciation:

• Wear and Tear: Physical deterioration due to constant use, friction, and passage of time.
• Obsolescence: The asset becoming outdated or inefficient due to technological advancements, changes in market demand, or improved production methods, even if it's still physically capable of functioning.
• Effluxion of Time: The reduction in value simply due to the passage of time, especially for assets with a legal life (e.g., leases, patents – though patents are amortized).
• Depletion: The reduction in value of natural resources (like mines, quarries, oil wells) due to extraction of the resource. This is a specific type of depreciation.

Why Depreciation Matters (Importance):

• Matching Principle: It helps match the cost of using an asset with the revenue it generates over its useful life, providing a more accurate picture of periodic profit.
• True & Fair View: Ensures that the Balance Sheet presents a true and fair view of the asset's value (Carrying Amount = Cost – Accumulated Depreciation).
• Fund for Replacement: While depreciation itself is a non-cash expense, it reduces reported profits, which can influence dividend distribution and encourage retention of funds for future asset replacement.
• Accurate Costing: Helps in determining the true cost of production by including the cost of asset usage.
• Compliance: Mandatory requirement under the Companies Act, 2013, and accounting standards.

Non-depreciable assets:
Generally, assets that do not lose value over time or usage are not depreciated. Examples include:

• Land: Typically appreciates in value or retains its value.
• Current Assets: Inventories, cash, receivables, etc., as they are not held for continuous use.
• Financial Assets: Investments, shares, bonds.
• Intangible Assets: These are amortized, not depreciated (e.g., goodwill, patents, trademarks).

Key Concepts & Terminology

• Cost of Asset: Includes the purchase price, import duties, non-refundable taxes, and any directly attributable costs to bring the asset to its working condition and location for its intended use (e.g., installation costs, freight, site preparation).
• Residual Value (Salvage Value): The estimated amount that an entity would currently obtain from disposal of the asset, after deducting the estimated costs of disposal, if the asset were already of the age and in the condition expected at the end of its useful life. Under Schedule II of the Companies Act, 2013, the residual value shall not be more than 5% of the original cost of the asset, unless a higher residual value is justified.
• Depreciable Amount: The cost of an asset (or other amount substituted for cost) less its residual value. This is the total amount that will be allocated as depreciation over the asset's useful life.
• Useful Life: The period over which an asset is expected to be available for use by an entity, or the number of production or similar units expected to be obtained from the asset by an entity. It's an estimate and can be different from the physical life.
• Carrying Amount (Book Value / Written Down Value): The amount at which an asset is recognized in the balance sheet after deducting any accumulated depreciation and accumulated impairment losses. Calculated as: Cost - Accumulated Depreciation.
• Accumulated Depreciation: The total depreciation charged on an asset from the date of its acquisition up to a particular date. It is a contra-asset account shown on the asset side of the Balance Sheet, reducing the gross block of assets.

Overview of Depreciation Methods

The Companies Act, 2013, and accounting standards require companies to choose a depreciation method that reflects the pattern in which the asset’s future economic benefits are expected to be consumed. The most common methods for CA Foundation are Straight Line Method and Written Down Value Method.

Key Insight: Regardless of the method chosen, the total depreciable amount (Cost - Residual Value) charged over the asset's useful life remains the same. The methods only differ in the timing or pattern of allocation of this amount over the years.

Straight Line Method (SLM) – Detailed

The Straight Line Method is the simplest and most widely used method of depreciation. Under this method, a fixed and equal amount of depreciation is charged every year throughout the useful life of the asset. This method assumes that the asset provides equal benefits over each year of its useful life.

Formula (KaTeX):
The annual depreciation under SLM is calculated as:

$$\text{Annual Depreciation} = \frac{\text{Cost of Asset} - \text{Residual Value}}{\text{Useful Life (in years)}}$$

Alternatively, it can be expressed as a percentage rate:

$$\text{Depreciation Rate (SLM)} = \frac{\text{Annual Depreciation}}{\text{Cost of Asset} - \text{Residual Value}} \times 100$$

Journal Entry:
The common journal entry to record depreciation at the end of each accounting period is:

Depreciation Expense A/c Dr.
    To Asset A/c (or Accumulated Depreciation A/c)

Note: If 'Accumulated Depreciation A/c' is used, the asset's original cost remains in the Asset A/c, and accumulated depreciation is shown as a deduction from it on the Balance Sheet. This is the preferred method for better disclosure.

Example (CA Foundation-style):
Machinery purchased on 1st April 2024:
Cost = ₹5,00,000
Residual Value = ₹50,000
Useful Life = 5 years

Calculation:
Depreciable Amount = ₹5,00,000 - ₹50,000 = ₹4,50,000
Annual Depreciation (SLM) = ₹4,50,000 / 5 years = ₹90,000

Pros:

1. Simplicity: Easy to understand and calculate.
2. Consistency: Provides a consistent charge to the Profit & Loss Account each year, making financial performance easier to compare.
3. Full Write-off: The asset's depreciable amount is fully written off over its useful life.

Cons:

1. Unrealistic Assumption: Assumes uniform usage and benefit throughout the asset's life, which may not be true (assets often used more in early years and require more maintenance later).
2. Ignores Obsolescence: Does not account for the faster decline in value due to technological obsolescence in early years.
3. Maintenance Costs: When maintenance costs increase in later years, combined with constant depreciation, it can lead to an increasing burden on profits.

When to use:
Best suited for assets where the benefits are expected to be uniform over their useful life, such as buildings, furniture, and fixtures.

Written Down Value (WDV) / Diminishing Balance Method – Detailed

The Written Down Value (WDV) method, also known as the Diminishing Balance Method or Reducing Balance Method, charges depreciation at a fixed percentage on the reducing balance (carrying amount) of the asset each year. This results in a higher depreciation charge in the initial years and a decreasing charge in subsequent years.

Formula (KaTeX):
Under WDV, the depreciation amount changes each year. The rate of depreciation (r) is applied to the carrying amount (Book Value) of the asset at the beginning of the year.

$$\text{Annual Depreciation} = \text{Carrying Amount at the beginning of the year} \times \text{Rate of Depreciation}$$

If the rate is not given, it can be derived using the formula (especially relevant for Schedule II compliance):

$$\text{WDV Rate (r)} = 1 - \left( \frac{\text{Residual Value}}{\text{Original Cost}} \right)^{1 / \text{Useful Life}}$$

Note: For CA Foundation, the WDV rate is usually provided in the question.

Example (CA Foundation-style):
Machinery purchased on 1st April 2024:
Cost = ₹5,00,000
Depreciation Rate = 20% p.a. (WDV)

Calculation:
Year 1 (2024-25):
Opening WDV (Cost) = ₹5,00,000
Depreciation = ₹5,00,000 \times 20% = ₹1,00,000
Closing WDV = ₹5,00,000 - ₹1,00,000 = ₹4,00,000

Year 2 (2025-26):
Opening WDV = ₹4,00,000
Depreciation = ₹4,00,000 \times 20% = ₹80,000
Closing WDV = ₹4,00,000 - ₹80,000 = ₹3,20,000

Pros:

1. Realistic: More realistic as assets generally lose more value and are more efficient in their early years.
2. Matching Principle: Higher depreciation in early years when the asset's efficiency is high, and lower in later years when maintenance costs tend to increase, thus balancing the total charge to the P&L.
3. Tax Benefits: Often preferred for tax purposes as it provides higher depreciation deductions in early years, leading to lower taxable profits and tax payments.

Cons:

1. Complexity: Calculation can be slightly more complex than SLM.
2. Never Zero: The asset's value never reduces to zero, even after its useful life, unless specifically adjusted in the last year to reach the residual value.

When to use:
Suitable for assets that lose value rapidly in early years, require more maintenance in later years, or are subject to quick obsolescence (e.g., machinery, vehicles, computers).

Units of Production (Output) Method

This method links depreciation directly to the actual usage or output of the asset. It is particularly suitable for assets whose useful life is best measured in terms of total production units, operating hours, or miles driven, rather than a time period.

Formula (KaTeX):
The depreciation is calculated in two steps:

1. Depreciation per unit of output/hour:

   $$\text{Depreciation per unit} = \frac{\text{Cost of Asset} - \text{Residual Value}}{\text{Estimated Total Units / Hours over Useful Life}}$$

2. Annual/Period Depreciation:

   $$\text{Period Depreciation} = \text{Depreciation per unit} \times \text{Actual Units / Hours Produced in the Period}$$

Example (CA Foundation-style):
Machine purchased for ₹10,00,000
Residual Value = ₹1,00,000
Estimated Total Production Capacity = 90,000 units
Actual production in Year 1 = 20,000 units

Calculation:
Depreciable Amount = ₹10,00,000 - ₹1,00,000 = ₹9,00,000
Depreciation per unit = ₹9,00,000 / 90,000 units = ₹10 per unit

Year 1 Depreciation = 20,000 units \times ₹10 = ₹2,00,000

Suitability:
Highly suitable for assets like manufacturing machinery, vehicles, or equipment where usage varies significantly from year to year. If the asset is idle, no depreciation is charged under this method.

Indian Regulatory Framework – Must-Know for CA Foundation

1. Companies Act, 2013 – Schedule II

• Mandatory for Companies: All companies registered under the Companies Act, 2013, must comply with Schedule II for calculating depreciation.
• Useful Lives: Schedule II prescribes useful lives for various classes of assets (e.g., buildings, plant & machinery, furniture, vehicles, computers). Companies can use different useful lives if justified and disclosed.
• Residual Value Cap: The residual value of an asset shall not be more than 5% of its original cost, unless a higher residual value is justified by technical assessment.
• Methods: Companies can use SLM, WDV, or any other method that reflects the expected pattern of consumption of the future economic benefits of the asset.

2. Accounting Standards (AS 10 / Ind-AS 16)

• AS 10 (Property, Plant and Equipment): For companies following Indian GAAP (Non-Ind AS), AS 10 provides guidance on accounting for PPE, including depreciation. It emphasizes that the depreciation method should reflect the pattern of consumption of economic benefits.
• Ind-AS 16 (Property, Plant and Equipment): For companies following Ind-AS, Ind-AS 16 is the relevant standard. It has similar principles to AS 10 but with some differences (e.g., revaluation model, component accounting, annual review of useful life/residual value/method).
• Consistency: Accounting standards generally require consistency in the depreciation method chosen. Any change in method is treated as a change in accounting estimate (prospective application) if it better reflects the pattern of consumption.

3. Income Tax Act, 1961 (Brief Mention for Context)

• Tax Depreciation: For income tax purposes, depreciation is generally allowed under the Written Down Value (WDV) method on 'blocks of assets' at prescribed rates.
• Difference from Books: The depreciation calculated for tax purposes often differs from the depreciation calculated for financial reporting (as per Schedule II/AS 10/Ind-AS 16). This difference leads to 'temporary differences' and the concept of Deferred Tax Assets/Liabilities, which is a more advanced topic for CA Intermediate/Final levels.

Accounting for Depreciation: Journal Entries & Ledger Accounts

There are primarily two methods to record depreciation in the books of accounts:

Method 1: When Provision for Depreciation Account (or Accumulated Depreciation Account) is NOT maintained.
In this method, the depreciation amount is directly credited to the Asset Account each year. The Asset Account will show its carrying amount (WDV) directly.

Journal Entry for Depreciation:

Journal Entry for Transferring Depreciation to P&L:

Method 2: When Provision for Depreciation Account (or Accumulated Depreciation Account) IS maintained.
This is the more common and preferred method. The depreciation amount is credited to a separate 'Provision for Depreciation Account' (a contra-asset account) instead of directly to the Asset Account. The Asset Account continues to show the asset at its original cost.

Journal Entry for Depreciation:

Journal Entry for Transferring Depreciation to P&L:

Treatment on Sale of Asset (when Provision for Depreciation A/c is maintained):
When an asset is sold, its accumulated depreciation needs to be transferred from the 'Provision for Depreciation Account' to the 'Asset Account' to determine the carrying amount at the time of sale. Then, the sale proceeds are recorded, and any profit or loss on sale is calculated.

1. Transfer Accumulated Depreciation:

   Date	Particulars	L.F.	Debit (₹)	Credit (₹)
   (Date of Sale)	Provision for Depreciation A/c Dr.		XXX
   	To Asset A/c			XXX
   	(Being accumulated depreciation transferred to Asset A/c)

2. Record Sale Proceeds:

   Date	Particulars	L.F.	Debit (₹)	Credit (₹)
   (Date of Sale)	Bank/Cash A/c Dr.		XXX
   	To Asset A/c			XXX
   	(Being asset sold)

3. Record Profit/Loss on Sale:

   • If Sale Price > Carrying Amount (Book Value): Profit

     Date	Particulars	L.F.	Debit (₹)	Credit (₹)
     (Date of Sale)	Asset A/c Dr.		XXX
     	To Profit & Loss A/c			XXX
     	(Being profit on sale of asset)

   • If Sale Price < Carrying Amount (Book Value): Loss

     Date	Particulars	L.F.	Debit (₹)	Credit (₹)
     (Date of Sale)	Profit & Loss A/c Dr.		XXX
     	To Asset A/c			XXX
     	(Being loss on sale of asset)

CA Exam Tip: Always clarify which method of accounting for depreciation is to be followed in the problem. If not specified, maintaining a 'Provision for Depreciation Account' is generally assumed for better presentation.

Short Form Questions (Conceptual & Numerical)

Q1. Define 'depreciable amount' and 'useful life' in the context of depreciation. Why is depreciation considered a non-cash expense?

Model Answer:

1. Depreciable Amount: It is the cost of an asset less its estimated residual value. This is the total amount of the asset's cost that will be systematically allocated as an expense over its useful life.
2. Useful Life: It is the period over which an asset is expected to be available for use by an entity, or the number of production units expected to be obtained from the asset.

Depreciation is a non-cash expense because it does not involve any actual outflow of cash during the period it is charged. It is an accounting adjustment to allocate a past cash outflow (the cost of the asset) over its useful life, reflecting the consumption of the asset's economic benefits.

Q2. A machine was purchased for ₹8,00,000 on 1st October 2023. Its estimated useful life is 10 years and residual value is ₹80,000. The company closes its books on 31st March every year. Calculate the amount of depreciation for the year ended 31st March 2024 using the Straight Line Method.

Model Answer:
Depreciable Amount = Cost - Residual Value = ₹8,00,000 - ₹80,000 = ₹7,20,000
Annual Depreciation (SLM) = Depreciable Amount / Useful Life = ₹7,20,000 / 10 years = ₹72,000

The machine was purchased on 1st October 2023. The accounting year ends on 31st March 2024. So, the machine was used for 6 months (October 2023 to March 2024).
Depreciation for the year ended 31st March 2024 = ₹72,000 \times (6/12) = ₹36,000

Q3. On 1st April 2023, a Plant was acquired for ₹12,00,000. Depreciation is to be charged at 15% per annum on the Written Down Value method. The company closes its books on 31st March every year. Calculate the depreciation for the year ended 31st March 2024 and 31st March 2025.

Model Answer:
Year ended 31st March 2024:
Opening WDV (Cost) = ₹12,00,000
Depreciation for 2023-24 = ₹12,00,000 \times 15% = ₹1,80,000
Closing WDV as on 31st March 2024 = ₹12,00,000 - ₹1,80,000 = ₹10,20,000

Year ended 31st March 2025:
Opening WDV = ₹10,20,000
Depreciation for 2024-25 = ₹10,20,000 \times 15% = ₹1,53,000
Closing WDV as on 31st March 2025 = ₹10,20,000 - ₹1,53,000 = ₹8,67,000

Q4. State any three advantages of the Written Down Value method over the Straight Line Method.

Model Answer:

1. More Realistic: It charges higher depreciation in earlier years when the asset is more efficient and provides greater economic benefits, aligning better with the actual decline in an asset's value.
2. Better Matching: When combined with increasing maintenance costs in later years, the WDV method tends to equalize the total charge (depreciation + maintenance) to the Profit & Loss Account over the asset's life, providing a more stable impact on profits.
3. Tax Benefits: In many jurisdictions (including India for income tax), WDV method provides higher depreciation deductions in initial years, leading to lower taxable income and tax payments in the asset's early life.

Q5. Explain the concept of 'Provision for Depreciation Account'. What is its purpose?

Model Answer:
A 'Provision for Depreciation Account' (also known as Accumulated Depreciation Account) is a separate ledger account maintained to accumulate the total depreciation charged on an asset over its life. Instead of crediting the depreciation directly to the Asset Account, it is credited to this provision account.

Purpose: Its main purpose is to allow the asset to be shown at its original cost in the Balance Sheet throughout its useful life, while the accumulated depreciation is presented separately as a deduction from the asset's gross value. This provides more transparent disclosure of the asset's original cost and the total depreciation charged to date, which is useful for financial analysis and asset management.

Q6. A machine costing ₹2,00,000 has an estimated total production capacity of 1,80,000 units and a residual value of ₹20,000. If the actual production in Year 1 was 40,000 units and in Year 2 was 35,000 units, calculate the depreciation for each year using the Units of Production method.

Model Answer:
Depreciable Amount = Cost - Residual Value = ₹2,00,000 - ₹20,000 = ₹1,80,000
Depreciation per unit = Depreciable Amount / Total Estimated Production = ₹1,80,000 / 1,80,000 units = ₹1 per unit

Depreciation for Year 1:
Actual production = 40,000 units
Depreciation = 40,000 units \times ₹1/unit = ₹40,000

Depreciation for Year 2:
Actual production = 35,000 units
Depreciation = 35,000 units \times ₹1/unit = ₹35,000

Case Studies (Comprehensive Scenarios with Full Solutions)

Case Study 1: Depreciation Schedules (SLM & WDV) and Journal Entries

On 1st April 2023, M/s Alpha Ltd. purchased a new machine for ₹10,00,000. The estimated useful life of the machine is 4 years, and its residual value is ₹1,00,000. The company closes its books on 31st March every year. Prepare the Depreciation Account and Machine Account for the first two years under both Straight Line Method and Written Down Value Method (at 30% p.a.), assuming Provision for Depreciation Account is NOT maintained.

Requirements:
(a) Prepare Machine Account and Depreciation Account for 2023-24 and 2024-25 using SLM.
(b) Prepare Machine Account and Depreciation Account for 2023-24 and 2024-25 using WDV (30% p.a.).

Model Solution:

Case Study 2: Sale of Asset with Provision for Depreciation Account

On 1st April 2021, a machine was purchased for ₹6,00,000. The company charges depreciation at 10% per annum on the Straight Line Method and maintains a Provision for Depreciation Account. The accounting year ends on 31st March. On 30th September 2023, this machine was sold for ₹4,50,000.

Requirements:
(a) Calculate depreciation for each year till the date of sale.
(b) Pass necessary journal entries for the sale of the machine on 30th September 2023, including the transfer of accumulated depreciation and recording profit/loss on sale.

Model Solution:

(a) Depreciation Calculation:
Annual Depreciation (SLM) = 10% of ₹6,00,000 = ₹60,000

• Depreciation for 2021-22 (1st April 2021 to 31st March 2022) = ₹60,000
• Depreciation for 2022-23 (1st April 2022 to 31st March 2023) = ₹60,000
• Depreciation for 2023-24 (1st April 2023 to 30th September 2023) = ₹60,000 \times (6/12) = ₹30,000

Total Accumulated Depreciation till 30th September 2023 = ₹60,000 + ₹60,000 + ₹30,000 = ₹1,50,000

Carrying Amount (Book Value) of Machine on 30th September 2023 = Original Cost - Accumulated Depreciation
= ₹6,00,000 - ₹1,50,000 = ₹4,50,000

(b) Journal Entries on 30th September 2023:

Case Study 3: Multiple Asset Purchases and Partial Year Depreciation (SLM)

M/s Brilliant Traders started business on 1st April 2022. They purchased the following assets:

• 1st April 2022: Furniture A for ₹2,00,000
• 1st October 2022: Furniture B for ₹1,50,000
• 1st January 2024: Furniture C for ₹1,00,000
  The company charges depreciation at 10% per annum using the Straight Line Method. The accounting year ends on 31st March. Prepare the Furniture Account for the years ended 31st March 2023 and 31st March 2024, assuming Provision for Depreciation Account is NOT maintained.

Requirements:
(a) Prepare the Furniture Account for the year ended 31st March 2023.
(b) Prepare the Furniture Account for the year ended 31st March 2024.

Model Solution:

(a) Furniture Account for the year ended 31st March 2023

(b) Furniture Account for the year ended 31st March 2024

Case Study 4: Change in Depreciation Method (Prospective Application)

A machine was purchased on 1st April 2021 for ₹5,00,000. Its useful life was estimated to be 5 years with a residual value of ₹50,000. The company initially adopted the Straight Line Method of depreciation. On 1st April 2023, the company decided to change its depreciation method to Written Down Value at 20% per annum, with retrospective effect. The accounting year ends on 31st March. (Note: For CA Foundation, changes in method are generally applied prospectively, but this problem illustrates the impact of retrospective vs. prospective).

Requirements:
(a) Calculate depreciation for 2021-22 and 2022-23 under SLM.
(b) Explain how a change in depreciation method is typically treated (prospective vs. retrospective) as per accounting standards for Foundation level.
(c) Recalculate depreciation for 2023-24 if the change is applied prospectively from 1st April 2023.

Model Solution:

(a) Depreciation under SLM (for 2021-22 and 2022-23):
Depreciable Amount = Cost - Residual Value = ₹5,00,000 - ₹50,000 = ₹4,50,000
Annual Depreciation (SLM) = ₹4,50,000 / 5 years = ₹90,000

• Depreciation for 2021-22 = ₹90,000
• Depreciation for 2022-23 = ₹90,000

Carrying Amount on 1st April 2023 (after 2 years of SLM depreciation):
= Original Cost - (2 \times Annual SLM Depreciation)
= ₹5,00,000 - (2 \times ₹90,000)
= ₹5,00,000 - ₹1,80,000 = ₹3,20,000

(b) Treatment of Change in Depreciation Method (for CA Foundation):
As per Accounting Standards (AS 10 / Ind-AS 16), a change in depreciation method is treated as a change in accounting estimate, not a change in accounting policy. Therefore, it should be applied prospectively. This means the change affects only the current and future periods, and prior period financial statements are not restated. The carrying amount of the asset at the date of change is depreciated over the remaining useful life using the new method.

(c) Depreciation for 2023-24 (Prospective Application of WDV):
From 1st April 2023, the method changes to WDV at 20% per annum.

Opening Carrying Amount on 1st April 2023 = ₹3,20,000
Depreciation for 2023-24 (WDV) = ₹3,20,000 \times 20% = ₹64,000

Note: If the problem specifically asks for retrospective application (which is rare for method changes at Foundation level), it would involve recalculating depreciation for all prior years with the new method and adjusting opening balances of retained earnings. This problem focuses on the typical prospective application.

Common Mistakes & CA Exam Tips

• Partial Year Depreciation: Always remember to prorate depreciation for assets purchased or sold during the year.
• Residual Value: Don't forget to deduct residual value when calculating depreciable amount for SLM or Units of Production. For WDV, residual value is usually only considered in the rate derivation or in the last year's adjustment.
• Method Consistency: Stick to the method specified in the problem (SLM or WDV). If not specified, choose one and state your assumption.
• Provision for Depreciation: Clearly understand the difference between maintaining and not maintaining a 'Provision for Depreciation Account' for journal entries and ledger postings.
• Sale of Asset: When an asset is sold, ensure you calculate depreciation up to the date of sale and correctly transfer accumulated depreciation (if a provision account is maintained) before calculating profit or loss on sale.
• Practice: Solve a variety of numerical problems covering different scenarios (new purchases, sales, partial years, different methods) to build confidence.

Key Takeaways

• Depreciation is a non-cash expense that allocates the cost of a tangible asset over its useful life.
• The primary methods are Straight Line (constant charge) and Written Down Value (decreasing charge).
• The total depreciable amount (Cost - Residual Value) remains the same across methods; only the timing differs.
• Understand the journal entries for recording depreciation and for asset disposal, especially with and without a 'Provision for Depreciation Account'.
• Be aware of Schedule II of the Companies Act, 2013, for useful lives and residual value caps.

Frequently Asked Questions (FAQs)

Q: What is depreciation in accounting?
A: Depreciation is the systematic allocation of the depreciable amount of a tangible asset over its useful life. It's an accounting method to spread the cost of an asset over the period it is expected to generate revenue.

Q: What are the main methods of depreciation for CA Foundation?
A: The main methods are Straight Line Method (SLM), which charges equal depreciation each year, and Written Down Value (WDV) method, which charges a higher amount in early years on the reducing balance. Units of Production method is also relevant.

Q: Is depreciation a cash expense?
A: No, depreciation is a non-cash expense. It represents the allocation of a past cash outflow (the asset's purchase cost) over its useful life. No cash is paid out when depreciation is recorded.

Q: What is the purpose of a 'Provision for Depreciation Account'?
A: The purpose of a Provision for Depreciation Account is to allow the asset to be shown at its original cost in the Balance Sheet, while the total accumulated depreciation is shown separately. This provides more transparent financial reporting.

Q: How is depreciation treated when an asset is sold?

If a Provision for Depreciation Account is maintained, the accumulated depreciation for that specific asset is transferred to the Asset Account. Then, the sale proceeds are recorded, and any profit or loss on sale (Sale Price vs. Carrying Amount) is recognized in the Profit & Loss Account.
