How to Calculate Depreciation Expense: A Step-by-Step Guide

Depreciation expense is a non-cash expense that businesses must record to account for the decline in the value of long-term assets over time. It is a critical component of accounting and financial reporting, as it provides a more accurate picture of a company's financial performance and position.

Calculating depreciation expense can be complex, depending on the method used and the type of asset being depreciated. However, understanding the basics of depreciation calculation is essential for businesses of all sizes.

In this article, we will walk through the steps involved in calculating depreciation expense, covering the most common depreciation methods and providing examples to illustrate the process. Learn how to correctly account for depreciation and gain a deeper understanding of this important aspect of accounting.

How to Calculate Depreciation Expense

To accurately calculate depreciation expense, it's important to understand the following key points:

• Identify Depreciable Assets
• Choose Depreciation Method
• Determine Asset's Useful Life
• Calculate Depreciation Rate
• Apply Depreciation Rate to Asset's Cost
• Record Depreciation Expense
• Review and Adjust as Needed
• Follow GAAP or Local Regulations

By following these steps and considering these important points, businesses can ensure that depreciation expense is calculated accurately and consistently, providing a clearer picture of their financial performance and position.

Identify Depreciable Assets

The first step in calculating depreciation expense is to identify the depreciable assets owned by the business. Depreciable assets are tangible assets that have a useful life of more than one year and are used in the business's operations to generate income.

Examples of depreciable assets include:

• Property and buildings
• Equipment and machinery
• Vehicles
• Furniture and fixtures
• Computer hardware and software

Land is not considered a depreciable asset because it does not have a limited useful life.

To determine if an asset is depreciable, businesses should consider the following factors:

• Is the asset tangible?
• Does the asset have a useful life of more than one year?
• Is the asset used in the business's operations to generate income?

If the answer to all three questions is yes, then the asset is depreciable.

Once the depreciable assets have been identified, the business can proceed to choose a depreciation method and determine the asset's useful life.

Choose Depreciation Method

Once the depreciable assets have been identified, the next step is to choose a depreciation method. The depreciation method determines how the cost of the asset will be allocated over its useful life.

• Straight-line method: This is the simplest and most commonly used depreciation method. Under the straight-line method, the cost of the asset is allocated evenly over its useful life. This results in a constant depreciation expense each year.
• Declining-balance method: This method allocates a larger portion of the asset's cost to the early years of its useful life. This results in a higher depreciation expense in the early years and a lower depreciation expense in the later years.
• Sum-of-the-years'-digits method: This method allocates the asset's cost based on the remaining useful life of the asset. This results in a higher depreciation expense in the early years and a lower depreciation expense in the later years.
• Units-of-production method: This method allocates the asset's cost based on the number of units produced by the asset. This results in a variable depreciation expense that fluctuates with the level of production.

The choice of depreciation method depends on a number of factors, including the type of asset, the expected pattern of usage, and the business's tax situation. Businesses should consult with their accountant to determine the most appropriate depreciation method for their specific circumstances.

Determine Asset's Useful Life

Once the depreciation method has been chosen, the next step is to determine the asset's useful life. The useful life of an asset is the period of time over which the asset is expected to be used in the business's operations.

There are a number of factors that can affect the useful life of an asset, including:

• The type of asset
• The expected usage of the asset
• The maintenance and repairs that are performed on the asset
• The technological advancements that may make the asset obsolete

Businesses can use industry guidelines, manufacturer recommendations, and their own experience to estimate the useful life of their assets.

It is important to note that the useful life of an asset for depreciation purposes may be different from the asset's actual physical life. For example, a business may decide to depreciate a computer over a period of five years, even though the computer may actually last for ten years or more.

Choosing a reasonable useful life for assets is important because it affects the amount of depreciation expense that is recorded each year. A shorter useful life results in a higher depreciation expense, while a longer useful life results in a lower depreciation expense.

Once the asset's useful life has been determined, the business can proceed to calculate the depreciation rate.

Calculate Depreciation Rate

The depreciation rate is a percentage that is used to calculate the depreciation expense for an asset each year. The depreciation rate is calculated by dividing 100% by the asset's useful life in years.

For example, if an asset has a useful life of five years, the depreciation rate would be 20% (100% / 5 years = 20%). This means that 20% of the asset's cost will be depreciated each year.

The depreciation rate can also be calculated using the following formula:

Once the depreciation rate has been calculated, it can be used to calculate the depreciation expense for the asset each year.

To calculate the depreciation expense, simply multiply the asset's cost by the depreciation rate.

For example, if an asset costs $10,000 and has a depreciation rate of 20%, the depreciation expense for the first year would be $2,000 ($10,000 * 20% = $2,000).

The depreciation expense is recorded on the income statement as a non-cash expense. This means that it does not affect the business's cash flow, but it does reduce the business's net income.

Apply Depreciation Rate to Asset's Cost

Once the depreciation rate has been calculated, it can be applied to the asset's cost to calculate the depreciation expense for each year of the asset's useful life.

• Straight-line method: Under the straight-line method, the depreciation expense is calculated by multiplying the asset's cost by the depreciation rate. For example, if an asset costs $10,000 and has a depreciation rate of 20%, the depreciation expense for the first year would be $2,000 ($10,000 * 20% = $2,000).
• Declining-balance method: Under the declining-balance method, the depreciation expense is calculated by multiplying the asset's book value (i.e., the asset's cost minus the accumulated depreciation) by the depreciation rate. For example, if an asset costs $10,000 and has a depreciation rate of 20%, the depreciation expense for the first year would be $2,000 ($10,000 * 20% = $2,000). The depreciation expense for the second year would be $1,600 ($8,000 * 20% = $1,600), and so on.
• Sum-of-the-years'-digits method: Under the sum-of-the-years'-digits method, the depreciation expense is calculated by multiplying the asset's cost by a fraction. The fraction is determined by adding up the digits of the asset's useful life and then dividing the number of years remaining in the asset's useful life by the sum of the digits. For example, if an asset costs $10,000 and has a useful life of five years, the sum of the digits would be 15 (5 + 4 + 3 + 2 + 1 = 15). The depreciation expense for the first year would be $3,333 ($10,000 * (5/15) = $3,333). The depreciation expense for the second year would be $2,667 ($10,000 * (4/15) = $2,667), and so on.
• Units-of-production method: Under the units-of-production method, the depreciation expense is calculated by multiplying the asset's cost by a rate per unit of production. The rate per unit of production is determined by dividing the asset's cost by the total number of units that the asset is expected to produce over its useful life. For example, if an asset costs $10,000 and is expected to produce 100,000 units over its useful life, the rate per unit of production would be $0.10 ($10,000 / 100,000 units = $0.10). The depreciation expense for the first year would be $1,000 (10,000 units produced * $0.10 per unit = $1,000). The depreciation expense for the second year would be $1,500 (15,000 units produced * $0.10 per unit = $1,500), and so on.

The depreciation expense is recorded on the income statement as a non-cash expense. This means that it does not affect the business's cash flow, but it does reduce the business's net income.

Record Depreciation Expense

Once the depreciation expense has been calculated, it is recorded on the income statement as a non-cash expense. This means that it does not affect the business's cash flow, but it does reduce the business's net income.

The depreciation expense is recorded in the following journal entry:

The depreciation expense is debited to the income statement, which reduces the business's net income. The accumulated depreciation is credited to a contra asset account. The contra asset account is used to track the total amount of depreciation that has been recorded for the asset over its useful life.

The accumulated depreciation account is also used to calculate the asset's book value. The book value of an asset is the asset's cost minus the accumulated depreciation.

The book value of an asset is important because it is used to determine the asset's gain or loss when it is sold.

Depreciation expense is an important non-cash expense that businesses must record to account for the decline in the value of their assets over time. By understanding how to calculate and record depreciation expense, businesses can ensure that their financial statements are accurate and informative.

Review and Adjust as Needed

It is important to review and adjust the depreciation expense calculation as needed. This may be necessary if the asset's useful life changes, if the asset is sold or retired early, or if there is a change in the depreciation method.

• Change in asset's useful life: If the asset's useful life changes, the depreciation rate will need to be recalculated. This may happen if the asset is used more or less than expected, or if there is a change in the technology that the asset uses.
• Sale or retirement of asset: If the asset is sold or retired early, the depreciation expense will need to be adjusted to reflect the actual time that the asset was used. This is done by calculating the difference between the asset's cost and its salvage value (i.e., the amount that the asset was sold for or scrapped for).
• Change in depreciation method: If the business changes its depreciation method, the depreciation expense will need to be recalculated using the new method. This may be done to better match the depreciation expense with the asset's actual pattern of usage.

By reviewing and adjusting the depreciation expense calculation as needed, businesses can ensure that their financial statements are accurate and informative.

Follow GAAP or Local Regulations

When calculating depreciation expense, it is important to follow the guidelines set forth by Generally Accepted Accounting Principles (GAAP) or local regulations.

• GAAP: GAAP is a set of rules and standards that govern the accounting practices of public companies in the United States. GAAP includes specific rules for calculating depreciation expense. These rules are designed to ensure that depreciation expense is recorded in a consistent and transparent manner.
• Local regulations: In some countries, there may be specific regulations that govern the calculation of depreciation expense. These regulations may differ from GAAP. Businesses that operate in these countries must comply with the local regulations when calculating depreciation expense.
• Consistency: It is important to apply the same depreciation method and useful life consistently from year to year. This will ensure that the depreciation expense is recorded in a consistent and transparent manner.
• Disclosure: Businesses must disclose their depreciation methods and useful lives in their financial statements. This information is important for investors and other users of the financial statements to understand how the depreciation expense is being calculated.

By following GAAP or local regulations and applying the depreciation methods and useful lives consistently, businesses can ensure that their depreciation expense calculation is accurate and transparent.
