Importance of depreciation
Here are the key reasons why depreciation is an essential part of modern accounting practices:
- Matching principle: This fundamental accounting principle ensures that expenses are recorded in the same accounting period as the revenues they help generate, providing a more accurate reflection of financial performance.
- Improved financial representation: Depreciation offers a clearer and more realistic view of a company’s financial position by accounting for the gradual reduction in asset value over time.
- Tax benefits: Depreciation is treated as a deductible expense, which helps reduce taxable income and, consequently, lowers the overall tax liability of a business.
- Asset management: It enables businesses to monitor the value of their assets effectively and supports informed planning for future repairs, upgrades, or replacements.
Why is calculating depreciation essential for businesses?
Here are the main reasons why depreciation is important in modern accounting:
- Matching principle: This means expenses should be recorded in the same period as the income they help to earn.
- Clearer financial picture: Depreciation shows a more accurate view of a company’s financial health and performance.
- Tax benefits: Depreciation is an expense that reduces taxable income, helping the company pay less tax.
- Asset management: It helps businesses keep track of the value of their assets and plan when to replace them in the future.
How to calculate depreciation?
When setting up a depreciation plan for an asset, there are three main things to consider:
- Depreciable base: This is the total cost of the asset minus its estimated resale value (called salvage value) at the end of its use. The total cost includes the purchase price and any extra costs to get the asset ready for use.
- Useful life: This is the estimated time the asset will be used before it becomes outdated or too worn out. It doesn’t always match the actual physical life of the asset.
- Best method: This is the way chosen to calculate depreciation. It should be logical and suit the type of asset. Some methods reduce value based on time, while others depend on how much the asset is used. Many businesses choose a simple method to keep things easy and reduce paperwork.
Methods of depreciation
The most commonly used depreciation methods are generally grouped into three main categories, although certain specialised methods may be applied in specific cases:
- Time-based methods: These assume that an asset provides equal economic benefit in each period of its useful life. A reliable estimate of useful life is essential when applying these methods. The most common example is the straight-line depreciation method.
- Activity-based methods: These methods calculate depreciation based on the asset’s actual usage or productivity. Usage may be measured in units produced, hours operated, or other relevant output indicators. Selecting an appropriate measure and estimating total lifetime output are key requirements. A common example is the units of production method.
- Reducing charge (accelerated depreciation) methods: These assume that assets lose value more quickly in the early years of use. As a result, higher depreciation is charged initially, with lower amounts in later years. When combined with maintenance costs, which typically rise over time, these methods can result in a more balanced view of total ownership cost. Examples include the sum-of-years’ digits method, declining balance method, and double declining balance method.
Straight-line depreciation method
The straight-line method is the simplest and most widely used time-based approach. It is calculated as:
Annual depreciation expense = (Cost − Salvage value) ÷ Useful life
Units of production method
This activity-based method links depreciation directly to usage or output, making it suitable where production varies significantly.
Annual depreciation expense = [(Cost − Salvage value) ÷ Total estimated production] × Units produced in the year
Sum-of-years’ digits method
This accelerated method applies a reducing fraction of the depreciable value based on remaining useful life. The denominator is the sum of the years’ digits (e.g., for five years: 5+4+3+2+1 = 15). The numerator reduces each year in line with remaining life.
Annual depreciation is calculated as:
(Cost − Salvage value) × (Remaining useful life factor ÷ Sum of years’ digits)
Declining balance method
This method applies a fixed depreciation rate to the reducing book value of the asset each year, resulting in lower charges over time.
Step 1: Annual depreciation rate = 1 ÷ Useful life
Step 2: Annual depreciation = Rate × (Cost − Accumulated depreciation)
Double declining balance method
This is a more accelerated version of the declining balance method, where the depreciation rate is double the straight-line rate. The same declining balance approach is then applied using this higher rate, resulting in faster write-down of asset value in the early years.
Types of depreciation with calculation and examples
Depreciation methods in India:
1. Straight-line depreciation:
- Simplest method.
- Deducts the same amount of depreciation annually from the asset's original cost.
- Formula: Depreciation = (Original Cost - Salvage Value) / Useful Life.
- Example: A machine costing Rs. 100,000 with a 5-year useful life depreciates by Rs. 20,000 annually.
2. Reducing balance method (Written-down value method):
- Applies a fixed percentage of depreciation to the remaining balance of the asset each year.
- Formula: Depreciation = Depreciation Rate × Book Value at the Beginning of the Year.
- Example: If the depreciation rate is 20% and the machine's initial value is Rs. 100,000, the depreciation in the first year is Rs. 20,000.
3. Sum-of-Years' digits method:
- Considers the total useful life of the asset.
- Calculates depreciation based on a fraction of the asset's original cost each year.
- Formula: Depreciation = (Remaining Useful Life / Sum of Years' Digits) × (Original Cost - Salvage Value).
- Example: For a machine with a 5-year useful life, the first-year depreciation is 5/15 of the original cost.
How businesses use depreciation for tax savings
Companies in India use depreciation to lower their tax payments under the Income Tax Act. When a business buys expensive equipment or assets, it cannot claim the full cost as an expense in one year. Instead, it deducts parts of the cost over several years, matching the time the asset is expected to be used.
The Income Tax Act allows businesses to claim depreciation on assets they own and use for their business or to earn income. Sometimes, there are provisions that allow quicker deductions on certain types of assets, helping businesses save on taxes earlier.
According to Indian tax rules, an asset must meet these conditions to be depreciated:
- It should be owned by the business (not leased).
- It must be used for business or income-generating purposes.
- It should have a useful life that can be reasonably estimated.
- It is expected to last more than one year.
- It should not be an excluded item, such as intangible assets (which are usually amortized) or assets used for building capital improvements.
Depreciation under the Income Tax Act, 1961 (India)
Depreciation is covered under section 32 of the Income Tax Act, 1961. It refers to the reduction in the value of an asset over time due to use, age, or wear and tear. Depreciation is claimed only for accounting and tax purposes – it helps reduce the amount of taxable income.
The law allows businesses to claim depreciation on both tangible assets (like buildings, factories, and machines) and intangible assets (like patents, trademarks, copyrights, franchises, or other business rights). For capital assets, the depreciation amount can be deducted from their original cost.
How depreciation impacts financial statements
Although a company pays for equipment in a single upfront cash payment, depreciation spreads this cost across multiple financial periods.
Companies are generally required to follow Generally Accepted Accounting Principles (GAAP), issued by the Financial Accounting Standards Board (FASB), when recording depreciation. These standards require expenses to be matched with the revenues they help generate.
Therefore, if a machine is used to produce goods over five years, its cost is allocated over those five years rather than being recorded as a single expense in the year of purchase.
Advantages of Depreciation
- Tax savings: Depreciation is a non-cash, tax-deductible expense. By recording it, businesses reduce their taxable income and lower their overall tax burden.
- Accurate financial reporting: Depreciation follows the matching principle by spreading the cost of an asset over the income it generates, giving a more realistic picture of profitability than charging the full cost upfront.
- Planning for asset replacement: Tracking depreciation helps businesses estimate how long an asset will last, making it easier to plan budgets and set aside funds for future replacements.
- Correct asset valuation: It keeps the balance sheet accurate by showing the true book value of assets as they age or become obsolete.
- Better cash flow management: Tax savings from depreciation release cash that can be reinvested in business growth, staffing, or marketing activities.
- Stronger loan applications: Well-maintained depreciation records reflect financial discipline and transparency, improving a business’s credibility when applying for loans.
Depreciation practical examples
- Business vehicle: If a company buys a car for Rs. 10 lakh, it can claim depreciation of 15%, which comes to Rs. 1.5 lakh in the first year. However, if the vehicle is used for less than 180 days in the year of purchase, only half the rate (7.5%) can be claimed for tax purposes.
- Electronics: A laptop bought for an employee at Rs. 60,000 qualifies for a higher depreciation rate of 40%, allowing a first-year deduction of Rs. 24,000.
- Office Fixtures: Items such as furniture, fans, and electrical fittings are depreciated at a rate of 10%.
- Car insurance (IDV): For personal vehicles, the Insured Declared Value (IDV) is calculated using standard depreciation rates set by IRDAI. For instance, a car that is 3 to 4 years old usually has 40% depreciation applied to its original ex-showroom price.
Difference between depreciation and amortization
| Aspect | Depreciation | Amortization |
| Type of assets | Tangible assets like machinery, equipment, buildings | Intangible assets like patents, copyrights, goodwill |
| Purpose | Reflects the decrease in value due to wear and tear, obsolescence, etc. | Spreads out the cost of intangible assets over their useful life |
| Calculation method | Methods like straight-line depreciation or reducing balance method | Typically calculated using the straight-line method |
| Common industries | Manufacturing, construction, real estate | Technology, pharmaceuticals, finance |
| Example | Depreciating the value of machinery over its useful life | Amortizing the cost of a patent over its legal life |
This table provides a clear comparison between depreciation and amortization, highlighting their differences in terms of assets, purpose, calculation methods, industries, and examples.
Difference between accounting depreciation and tax depreciation
| Aspect | Accounting depreciation (Companies Act, 2013) | Tax depreciation (Income Tax Act, 1961) |
| Governing law | Regulated by the Companies Act, 2013 (Schedule II) and applicable accounting standards (Ind AS / AS 6). | Governed by the Income Tax Act, 1961, mainly Section 32 and related rules. |
| Main objective | To show a true and fair view of financial performance by spreading the cost of an asset over its useful life. | To calculate taxable income correctly and determine allowable depreciation for tax purposes. |
| Basis of calculation | Calculated on the estimated useful life of each individual asset and its residual value. | Calculated using the “block of assets” concept with fixed depreciation rates prescribed under tax laws. |
| Methods allowed | Straight-Line Method (SLM), Written Down Value (WDV), or Unit of Production method. | Mostly the Written Down Value (WDV) method is used, except for certain cases like power generation units where SLM is allowed. |
| First-year usage rule | Depreciation is charged proportionately based on the actual number of days the asset is used. | Full depreciation is allowed if the asset is used for more than 180 days; otherwise, only 50% of the normal rate is allowed. |
| Resulting difference | Differences in depreciation create timing differences, recorded as deferred tax assets or liabilities in the accounts. | Tax returns follow Income Tax Act rules, with adjustments made to reconcile accounting profit and taxable income. |
How does depreciation affect your business loan eligibility?
Depreciation can affect your chances of getting a business loan in both good and bad ways.
On the positive side, lenders often see depreciation as helpful because it is a non-cash expense — meaning no actual money is spent. When depreciation is added back to your net profit, your cash flow (EBITDA) looks stronger, which shows that your business is better able to repay the loan.
On the negative side, depreciation reduces the value of your assets in the balance sheet. If you plan to use these assets as security (collateral) for a secured business loan, the loan amount will be based on their lower, depreciated value.
