When a company obtains an asset, such as a vehicle, goodwill, or a corporate headquarters, that asset often has a long useful life. Instead of recognising its value only in the year of acquisition, it's more accurate to spread the cost of these assets over their useful lifespan. This practice allows businesses to deduct these expenses from their taxable income, reducing their tax liability. Amortisation and depreciation are the primary methods for calculating the value of such assets. The key distinction between them lies in the type of asset involved, and there are variations in the methods, calculation components, and how they are reported on financial statements. In this article we will understand key aspects of Amortisation vs. Depriciation.

What is amortisation?

Amortisation is an accounting technique used to periodically lower the book value of a loan or an intangible asset over a set period of time. When applied to a loan, amortisation focuses on spreading out loan payments over time. This is done by dividing the total cost of the loan into equal payments over the life of the loan. The payments are then used to pay off both the principal and interest on the loan. The principal is the amount borrowed, while the interest is the cost of borrowing that amount.

Amortisation is also used to write off the cost of intangible assets such as patents, trademarks, and copyrights over their useful life. This is done to reflect the use of these types of assets more accurately. The expense amounts are then used as a tax deduction, reducing the tax liability of the business.

The process of amortisation is similar to depreciation, which is used to write off the cost of tangible assets such as buildings and equipment over their useful life. However, there are differences in how these two methods are calculated and presented on financial statements.

Amortisation calculation example

Here is an example of how to calculate amortisation:

Let us say a company purchases an asset for Rs. 100,000 with a useful life of 10 years. The company can use the straight-line method to calculate the amortisation expense each year. The formula for straight-line amortisation is:

Amortisation expense = (Cost of asset - Salvage value) / Useful life

In this case, the calculation would be:

Amortisation expense = (Rs. 100,000 - Rs. 0) / 10

Amortisation expense = Rs. 10,000 per year

So, the company would record an amortisation expense of Rs. 10,000 each year for 10 years.

Types of Amortization

Here are some common types of amortization:

  1. Straight-line amortization: With this method, the borrower makes equal payments over the loan term. Each payment comprises both interest and principal components. As the loan balance decreases, the interest portion of the payment also reduces. 
  2. Balloon payment amortization: In this approach, smaller payments are made over the loan term, followed by a significant "balloon" payment at the end. This strategy can lower initial monthly payments, making it suitable for mortgages and other long-term loans.
  3. Negative amortization: Negative amortization occurs when the loan payments are insufficient to cover the interest accrued. The unpaid interest is added to the principal balance, causing the loan to grow over time.
  4. Interest-only amortization: With this method, the borrower pays only the interest on the loan for a specified period. The principal amount is repaid in a lump sum at the end of the term. This can be beneficial for borrowers who anticipate increased income in the future.

Accelerated amortization: Accelerated amortization involves making larger-than-required payments to reduce the loan term and total interest paid. This strategy can save money on interest costs over the life of the loan.

What is depreciation?

Depreciation serves as an accounting method used to spread out the cost of tangible assets over their useful lifespan. This gradual expense recognition method allows businesses to match the use of assets with the revenue they generate, promoting financial accuracy. Depreciation involves deducting an asset's cost over its useful life, with assets categorised into different classes, each with its specific lifespan. These assets are known as depreciable assets.

Various depreciation methods, like straight-line or accelerated, can be employed, depending on the asset and financial strategy. Accumulated depreciation signifies the total depreciation recorded on an asset up to a particular date. The carrying value on the balance sheet is the asset's historical cost minus accumulated depreciation, reflecting its remaining value. This residual value is termed the salvage value.

Depreciation calculation example

Let us say a company purchases a machine for Rs. 10,000 with a useful life of 5 years and no salvage value. The company can use the straight-line method to calculate the depreciation expense each year. The formula for straight-line depreciation is:

Depreciation expense = (Cost of asset - Salvage value) / Useful life

In this case, the calculation would be:

Depreciation expense = (Rs. 10,000 - Rs. 0) / 5

Depreciation expense = Rs. 2,000 per year

So, the company would record a depreciation expense of Rs. 2,000 each year for 5 years.

Types of Depreciation

Here are some common depreciation methods:

  1. Straight-line depreciation: This method allocates equal depreciation expense to each period of the asset's useful life. It's a simple approach that considers the asset's lifespan and its decline in value over time. Declining balance depreciation: This method allocates higher depreciation expense in the early years of the asset's life and lower expense in later years. This reflects the idea that assets often lose value more rapidly in their early years of use.
  2. Declining balance depreciation: This method allocates higher depreciation expense in the early years of the asset's life and lower expense in later years. This reflects the idea that assets often lose value more rapidly in their early years of use.
  3. Annual depreciation: This method involves reducing the asset's value by a fixed amount each year, gradually decreasing its book value over time.
  4. Units of production depreciation: This method allocates depreciation expense based on the number of units the asset produces. It's suitable for assets whose value declines with usage rather than with the passage of time. Accelerated depreciation: Accelerated depreciation methods, such as the double declining balance method, allocate higher depreciation expense in the early years of the asset's life. This can result in significant tax benefits in the early years, as it reduces taxable income.
  5. Accelerated depreciation: Accelerated depreciation methods, such as the double declining balance method, allocate higher depreciation expense in the early years of the asset's life. This can result in significant tax benefits in the early years, as it reduces taxable income.
  6. Double declining balance depreciation: This is an accelerated depreciation method that doubles the straight-line depreciation rate. It's particularly useful for assets that rapidly lose value in their early years, such as technology equipment.

Amortisation vs. depreciation: Key differences

Key differences between amortization and depreciation are-

Amortization

Depreciation

Used to expense intangible assets over their useful life

Used to expense tangible assets over their useful life

Straight-line method is often the only method used

Many different methods are used

Assets expensed using this method typically do not have any resale or salvage value

Assets expensed using this method typically have some salvage value

Examples of intangible assets that are expensed through amortisation include patents, trademarks, franchise agreements, copyrights, costs of issuing bonds to raise capital, or organisational costs

Examples of tangible assets that are expensed through depreciation include buildings, equipment, machinery, and vehicles

The expense amounts are then used as a tax deduction, reducing the tax liability of the business

The expense amounts are then used as a tax deduction, reducing the tax liability of the business

Amortisation is shown on the income statement as an expense

Depreciation is shown on the income statement as an expense

Amortisation is shown on the balance sheet as a contra-asset account

Depreciation is shown on the balance sheet as accumulated depreciation


Conclusion

Understanding the distinctions between amortisation and depreciation is vital for accurate financial reporting and tax planning. Both methods serve the purpose of allocating the cost of assets over their useful life, but they are applied to different types of assets—intangible and tangible, respectively.

It is crucial for businesses and individuals alike to grasp these accounting practices to make informed decisions regarding their assets, investments, and financial strategies.

Frequently asked questions

What is an example of amortisation?

Example A: A business purchases a ₹10,00,000 software licence with an expected lifespan of five years. Using the straight-line method, the annual depreciation expense would be ₹2,00,000 for the next five years. Consequently, at the end of the five-year period, the carrying value of the asset would be zero.

Is amortisation a debit or credit?

The accounting treatment for amortisation expense is summarised as follows: a debit to the amortisation expense account and a credit to the accumulated amortisation account.

How to calculate depreciation?

To calculate depreciation using the straight-line method, subtract the asset's residual value (what you expect it to be worth at the end of its useful life) from its cost. The result is the depreciable amount, or the amount that can be depreciated. Divide this amount by the number of years in the asset's useful life. Divide by 12 to find the monthly depreciation for the asset.

What is an example of depreciation and amortization?

To calculate depreciation using the straight-line method, subtract the asset's salvage value (its estimated value at the end of its useful life) from its cost price. This difference is called the depreciable amount. Divide this amount by the asset's useful life in years. This gives you the annual depreciation expense. To find the monthly depreciation, divide the annual depreciation by 12.

For example:

Suppose a business buys a machine worth ₹10,00,000. It's estimated to last 10 years and have a salvage value of ₹1,00,000.

  • Depreciable amount: ₹10,00,000 - ₹1,00,000 = ₹9,00,000
  • Annual depreciation: ₹9,00,000 / 10 years = ₹90,000
  • Monthly depreciation: ₹90,000 / 12 = ₹7,500

So, the business can claim ₹90,000 as a depreciation expense each year, or ₹7,500 each month, to reduce its taxable income.

One of the most common examples of amortization is paying off a home loan. When you take a home loan, you borrow a certain amount of money from a lender. To repay this loan, you make regular payments over a fixed period. Each payment consists of two parts:

  1. Principal Payment: This portion of the payment reduces the outstanding loan amount.
  2. Interest Payment: This portion of the payment covers the interest charged on the outstanding loan balance.

As you make regular payments, the principal portion of each payment increases, while the interest portion decreases. This is because the outstanding loan balance is gradually reducing, so the interest charged on it also decreases
