A physical asset’s worth declines over time after purchase. Some declines happen faster than others. When you try to resell the item, you’ll probably learn that, in most circumstances, you won’t obtain the price you initially spent. It’s known as depreciation. If you own a business, you may deduct the cost of an asset’s depreciation from your taxes. We describe the fundamentals of depreciation and the most accurate method to determine its value for tax reasons in this post.
What You Should Know
- Depreciation is the term used to describe how much of an asset’s original worth remains over time.
- Companies can deduct the expense over the period of the asset’s useful life in order to recoup the cost of an eligible asset.
- According to generally recognized accounting standards, the straight-line technique is the simplest and most often used methodology to compute depreciation.
- Divide the remaining amount by the asset’s anticipated useful life after deducting the salvage value from the asset’s purchase price.
Depreciation: What Is It?

Depreciation is the term used to describe how much of an asset’s original worth remains over time. The asset’s usage or obsolescence causes this value to be generated. Vehicles, plants, equipment, machinery, and real estate are examples, although they are not necessarily restricted to these. As a result, as soon as you buy a car, it starts to lose value or depreciate. It gradually loses a specific proportion of its remaining value as a result of how it is operated, its state, and other aspects.
Depreciation is a company cost that is tax deductible. By deducting the expense throughout the period of the asset’s useful life, it gives firms a mechanism to recoup the price of a qualified item. If a company doesn’t take asset depreciation into account, it might expect a significant impact on its profitability.
The earnings of a company that doesn’t take asset depreciation into account might be significantly impacted.
According to generally accepted accounting principles (GAAP), there are numerous different ways for a business to determine how much an asset depreciates in order to qualify for a tax deduction:
- Falling Balance: Under this technique, the early years of an asset’s life are recorded as having higher depreciation costs, whereas the latter years have lower costs.
- With the double-declining approach, assets deteriorate twice as quickly as they would using the conventional declining balance method. Moreover, it takes into consideration that depreciation costs are higher in the early years of an asset’s life and lower in the later years.
- Digits from the Sum of the Years: The asset’s anticipated life is summed together to determine depreciation using this procedure. After that, each year is divided by that sum, starting with the first year’s larger number.
- Production Units: While using this strategy, businesses may take larger deductions. This is thus because an asset’s worth is determined by how many units it creates, not by how long it is in use.
- The most often used approach for estimating depreciation is the straight-line method. The value is determined by dividing the total number of years a corporation anticipates using the asset by the difference between the asset’s cost and estimated salvage value.
Straight-Line
The most typical approach for calculating depreciation under GAAP is the straight-line method, often known as the straight-line basis. This approach also makes depreciation calculation the easiest. It is the most reliable way, produces less mistakes, and smoothly transfers from company-prepared financial statements to tax filings.
By deducting the salvage value from the asset’s purchase price, the straight-line method of depreciation computes the asset’s consumption over time. The asset’s anticipated useful life is then split by that sum.
This is one instance. Let’s say a $3,500 delivery vehicle is purchased by a catering business. The van will be used for five years and the projected salvage value is $1,000. The yearly depreciation is determined by applying the straight-line method’s formula, which is as follows:
($3,500 – 1,000) ÷ 5 = $500.
Thus, the van will lose $500 in value per year for the following five years.
The straight-line approach calculation is multiplied by the percentage of months left in the year of purchase if the asset is bought on a date other than the first of the year. Considering the aforementioned example, if the vehicle was bought on October 1, depreciation would be computed as follows:
$125 is the result of (3 months / 12 months) x ($3,500 – 1000) / 5.
The catering business deducts $125 in the first year.
