Depreciation is useful in assisting companies in the distribution of the expense on a tangible item over the time period in which it is supposed to yield economic benefit. Among the many approaches that could be utilized to calculate the depreciation of an asset for accounting purpose, the straight line depreciation approach could be regarded as one of the easiest to understand approaches. Under this approach, the same amount of depreciation is recorded each year from the time the asset begins generating economic benefits till it reaches its end of life.
In this blog post, we will discuss straight-line depreciation formula, data required to calculate depreciation, examples, the strengths of the approach, and depreciation accounting.
Understanding Straight-Line Depreciation and Its Purpose in Accounting
Straight-line depreciation is a depreciation process in which the cost of a depreciable tangible asset is written off uniformly over its expected useful life. Since the amount of the expense is fixed during each accounting period, the depreciation is fairly simple to compute, record, and describe.
Depreciation is more than just an accounting process for businesses; it assists in showing the cost of a long-term asset in the accounting periods during which the asset is used.
What Is Straight-Line Depreciation?
Straight-line Depreciation is a method wherein the depreciable cost of the asset is allocated evenly through its useful life. The company depreciates the same cost each period during the accounting period.
This method may be appropriate when the asset will deliver relatively similar benefit through the duration of its useful life. Examples of such assets could include office equipment, furniture, machines, vehicles, among others.
What Information Is Needed to Calculate Depreciation?
The following three factors are necessary in order to do a simple calculation of depreciation using the straight line method:
- Cost of the asset;
- Salvage value; and
- Useful life of the asset.
Cost of the asset refers to the cost incurred on purchasing the asset and making it ready for use. Salvage value refers to the estimated value of the asset at the end of its useful life. Useful life refers to the period during which the asset will be used by the company.
Why Accurate Depreciation Matters
Depreciation recorded correctly ensures that there is no overvaluation or underestimation of expenses for the business organization. It also ensures that the financial statement has a fair presentation of the expense relating to the assets.
With many fixed assets being managed in a business organization, it could be difficult for depreciation calculations to be done easily. This is where professional accounting service comes into play.
How to Calculate the Straight-Line Depreciation Formula
Once the information regarding the asset is obtained, the computation becomes very straightforward. Nevertheless, companies will have to use the formula regularly and make appropriate estimates for useful life and scrap value.
The process below will illustrate how the computation is done and how the expense computed can be recorded in the accounting system.
Straight-Line Depreciation Formula
The basic straight-line depreciation formula is:
Annual Depreciation Expense = (Cost of Asset − Salvage Value) ÷ Useful Life
For example, suppose a business purchases equipment for $20,000, estimates its salvage value at $2,000, and expects to use it for 6 years.
Annual depreciation = ($20,000 − $2,000) ÷ 6
Annual depreciation = $18,000 ÷ 6 = $3,000
The business would therefore recognize $3,000 of depreciation expense per year, assuming the asset is placed in service at the beginning of the relevant period.
Example of Monthly Depreciation
The above computation can be worked out in monthly figures where a company uses monthly accounting statements. In the previous case, the yearly figure of depreciation is $3,000.
Monthly depreciation = $3,000 ÷ 12 = $250
Depreciation expense of $250 would be taken in every complete month throughout the depreciable life of the asset. In fact, the actual figure for the first year will depend upon the date of placing the asset into use within the year under consideration.
Recording Depreciation in the Accounts
Depreciation is usually recognized as an expense in the income statement. The accumulated depreciation balance is deducted from the asset’s book value but not from the original asset cost account.
A basic journal entry would be:
|
Account |
Debit |
Credit |
|
Depreciation Expense |
$250 |
— |
|
Accumulated Depreciation |
— |
$250 |
Maintaining these entries consistently helps businesses keep their fixed-asset records organized and makes financial reporting easier to review.
Applying Straight-Line Depreciation in Business Accounting
Despite being very easy to use, depreciation becomes complicated when many assets are owned or there is a need for maintaining separate books of accounting and taxation. At such times, good accounting practices come in handy.
It must be noted that there can be discrepancies between the rules governing depreciation in accounting books and those used in tax returns. As such, the accounting method used cannot automatically be the tax return method.
Straight-Line vs. Other Depreciation Methods
The straight-line depreciation allocates the same amount of expense throughout the useful life of the asset. There are other types of depreciation that result in different depreciation expenses based on the pace of losing usefulness.
For instance, accelerated depreciation methods such as the double-declining-balance method allocate more depreciation in the early years of the life of the asset while units of production depreciate based on actual use of the asset.
|
Method |
Depreciation Pattern |
Common Consideration |
|
Straight-line |
Equal each period |
Simple and consistent allocation |
|
Double-declining balance |
Higher earlier |
Suitable when assets lose value faster initially |
|
Units of production |
Based on usage |
Useful when consumption varies with production |
The appropriate method depends on the nature of the asset, the applicable accounting framework, and the purpose of the financial statements.
Book Depreciation and Tax Depreciation Are Not Always the Same
An important difference between the two is the difference between depreciation that is used in accounting records versus depreciation that is used for tax purposes. Tax laws might require the use of particular periods or methods for recovering the cost of property that are different from what the company has done in its accounting records.
The rules for U.S. companies when it comes to tax depreciation include the use of MACRS and accelerated depreciation for qualified assets under provisions like section 179.
When Should Businesses Consider Professional Accounting Services?
Straight-line depreciation is made more difficult with many assets purchased at various dates, asset enhancements, asset disposal, partial-year asset usage, or changing estimates. Keeping manual schedules for depreciation of fixed assets can be an unnecessary burden for the administration.
The accounting profession will assist organizations in managing depreciation schedules, recording periodic entries, reconciling fixed assets, and reporting financial data for both management and tax purposes. This enables the owners to concentrate on their core activities without compromising their financial records.
This straight-line depreciation calculation is easy to apply as a technique for allocating the cost of an asset uniformly over its estimated useful life. The method involves determining the difference between the cost of the asset and the salvage value, then dividing that difference by its useful life to get the annual depreciation expense.
Maintaining correct depreciation records contributes to accuracy in financial statements and efficient asset management. But business entities have to differentiate between book depreciation and tax depreciation due to the different accounting rules. In cases where there is difficulty in accounting for fixed assets, accounting services would be essential.
