Depreciation Definition: Types, How to Calculate

What is depreciation definition? Why this term can be said to be a crucial concept for businesses and investors to understand. In brief, depreciation is an accounting term that describes the decrease in value of an asset over time. It indeed has a significant impact on financial statements and tax obligations. In this article by Viindoo, we will explore what depreciation is, how it works, and its importance.

Depreciation Definition

To answer the question of what is depreciation definition, depreciation is the process of allocating the cost of an asset over its useful life. This includes tangible assets such as buildings, machinery, and vehicles, as well as intangible assets such as patents and trademarks. Accumulated depreciation reflects the fact that assets lose value over time due to wear and tear, obsolescence, and other factors.

The Importance of Depreciation

Let’s explore why depreciation is essential and how it affects financial reporting and budgeting, tax obligations, and the balance sheet.

Accurately Reflects the Cost of an Asset over its Useful Life

Depreciation accurately reflects the cost of an asset over its useful life. This is essential for financial reporting and budgeting purposes, as it enables businesses to spread out the cost of an asset over the period that it generates revenue. By allocating the cost of an asset over its useful life, businesses can more accurately determine their profitability and make informed financial decisions.

Reduces Tax Burden

Depreciation also reduces the tax burden of a business. The Internal Revenue Service (IRS) allows businesses to deduct the cost of an asset over time, rather than all at once. This is because an asset generates revenue over a period of time, and it is only fair to tax the income generated by the asset during that time.

For example, suppose a business purchases a piece of equipment for $50,000 that has a useful life of ten years. Using the straight-line depreciation method, the business can deduct $5,000 per year for ten years. This reduces the business's taxable income by $5,000 each year, reducing its tax liability.

Affects the Balance Sheet

Depreciation affects the balance sheet because as the asset loses value over time, depreciation increases. Depreciation is a contra-asset account, meaning it is subtracted from the asset's cost to determine its net book value.

The net book value is the value of the asset that is reported on the balance sheet. As the depreciation of fixed assets increases, net book value decreases. This can have significant implications for financial reporting, as it affects a business's financial ratios and can impact investment decisions.

Types of Depreciation

 In fact, there are several types of fixed asset depreciation methods that businesses can use, each with its unique characteristics and advantages. Refer to the below information to know the types of depreciation with examples.

Straight-line Depreciation​

Straight-line depreciation is the most commonly used method for calculating depreciation. It allocates an equal amount of the asset's cost for each year of its useful life. This method is simple and easy to understand, making it ideal for businesses that have assets with a predictable and consistent useful life.

For example:

Declining Balance Depreciation

The declining balance method is a more aggressive method of depreciation that allocates a higher percentage of the asset's cost to the earlier years of its useful life. This means that the depreciation expense decreases over time. This method is ideal for assets that lose their value quickly and have a higher rate of depreciation in the early years of their useful life.

For example:

Declining Balance Depreciation

Units-of-Production Depreciation

The units-of-production method allocates depreciation based on the asset's usage, rather than time. This method is ideal for assets that are used to produce goods or services, and their useful life is determined by the number of units they produce. This method allows businesses to allocate the cost of the asset more accurately and can result in a more accurate representation of the asset's value.

For example:

 Units-of-Production Depreciation

Sum-of-Years-Digits Depreciation

The sum-of-years-digits method (SYD) allocates a higher percentage of the asset's cost to the earlier years but at a decreasing rate. This means that the depreciation amount decreases over time, but not as aggressively as the declining balance method. This method is ideal for assets that lose their value more quickly in the early years of their useful life.

For example: 
- Consider a piece of equipment that costs $10,000 and has an estimated useful life of 5 years and a $0 salvage value. 
- To calculate the sum-of-the-years-digits depreciation: 1+2+3+4+5 = 15.
- The remaining life at the beginning of year 1 is 5,...
Set up a schedule:

Note:  The SYD depreciation method is not widely recognized and applied in international accounting standards such as IFRS. However, it is still used in some countries based on local accounting regulations and the flexibility to choose an appropriate depreciation method for their assets.

How to calculate depreciation?

There are different depreciation methods, but the most commonly used are the straight-line method, declining balance method, and units of production method. Here's a brief explanation of how to calculate depreciation using the straight-line method, which is the simplest and most straightforward approach:

  • Determine the cost of the asset: This includes the purchase price of the asset as well as any additional costs incurred to bring the asset into use, such as shipping or installation expenses.
  • Determine the salvage value: The salvage value is the estimated residual value of the asset at the end of its useful life. It represents the expected value of the asset after it has been fully depreciated. If you don't have a specific salvage value, you can assume it to be zero.
  • Determine the useful life: This refers to the estimated duration or number of years over which the asset will be used in your business operations. It is typically based on factors such as wear and tear, technological obsolescence, or legal requirements.
  • Calculate the annual depreciation expense: Using the straight-line method, you divide the difference between the cost of the asset and its salvage value by the useful life of the asset.

FAQs

What is the difference between depreciation and amortization?

Depreciation applies to tangible assets, such as buildings and equipment, while amortization applies to intangible assets, such as patents or copyrights. Both methods allocate the cost of the asset over its useful life, but they are specific to different asset types.

Depreciation can have tax benefits as it reduces taxable income, which in turn lowers the tax liability. Governments often allow businesses to deduct depreciation expenses from their taxable income, resulting in potential tax savings.

Once depreciation is recorded, it is generally not reversed or changed unless an error occurred. However, changes in estimates related to useful life, salvage value, or depreciation method may be necessary and should be disclosed appropriately.

No, depreciation is an accounting concept representing the systematic allocation of an asset's cost over its useful life. The decline in market value is influenced by external factors such as supply and demand, market conditions, and economic factors, which are not directly related to depreciation.

Viindoo Accounting software supports two methods: Straight-line depreciation and Declining balance depreciation.

Hopefully, through the article, readers can learn the depreciation definition, how to calculate depreciation, and why knowing depreciation is essential.
