Straight-line depreciation is a method of allocating the cost of a tangible fixed asset evenly over its useful life. This means that the asset’s value is reduced by the same amount each accounting period until it reaches its salvage value, or the estimated residual value at the end of its useful life. Straight-line depreciation is the most straightforward and commonly used depreciation method due to its simplicity and ease of application. Using the straight-line depreciation method, the business finds the asset’s depreciable base is $40,000.
Step 1: Calculate the Total Cost of the Asset
- The IRS updates IRS Publication 946 if you want a complete list of all assets and published useful lives.
- This formula for calculating asset value involves dividing the cost of an asset by its useful life, resulting in a constant rate of Depreciation per period.
- Straight line depreciation is the easiest depreciation method to calculate.
- With the consistent amount you can claim yearly, there aren’t any surprises or additional formulas to work out come tax time.
- A company may elect to use one depreciation method over another in order to gain tax or cash flow advantages.
- This is a very widely used method, which is of course dependent on the type of the asset and the company rules and policies regarding accounting procedure.
For example, suppose an asset having a depreciable cost of $5000 and a useful life of 5 years is purchased in the middle of an accounting year. In that case, the amount of depreciation expense in the first accounting year will be half of the full year’s depreciation charge. Common examples of tangible assets include machinery, equipment, and furniture and fixtures. These assets typically have a predetermined useful life, which makes them suitable for the straight line depreciation method.
Why Would You Not Choose This Method?
- By a large margin, the most easily understandable and widely-used depreciation method is the straight-line method.
- Another factor affecting straight line depreciation calculations is the salvage value.
- Straight-line depreciation is a consistent and predictable way to track the value of assets over time, making it easy to incorporate into your regular business accounting practices.
- It is most useful when an asset’s value decreases steadily over time at around the same rate.
- The car cost Bill $10,000 and has an estimated useful life of 5 years, at the end of which it will have a resale value of $4000.
This calculation results in a fixed depreciation expense that remains constant throughout the asset’s useful life, making it a preferred choice for businesses due to its simplicity. It’s used to reduce the carrying amount of a fixed asset over its useful life. With straight line depreciation, an asset’s cost is depreciated the same amount for each accounting period. You can then depreciate key assets on your tax income statement or business balance sheet. Straight line depreciation allocates an equal amount of depreciation expense to each period over the asset’s useful life.
Method to Get Straight Line Depreciation (Formula)
One of the key factors affecting straight line depreciation is the useful life of an asset. The useful life refers to the period over which an asset is expected to provide benefits to an organization. It is an estimate and can vary due to various reasons, such as technological advancements, physical wear and tear, and changes in regulations. The total depreciable cost is divided by the useful life to calculate the annual depreciation expense.
Finishing the formula, the business finds the asset’s annual depreciation amount is $4,000. The entire value of the asset ($40,000 depreciable base) will be reclassified into the expense account over time. When you use the straight-line depreciation formula, the expense journal entry will be the same each year. For example, due to rapid technological advancements, a straight line depreciation method may not be suitable for an asset such as a computer. A computer would face larger depreciation expenses in its early useful life and smaller depreciation expenses in the later periods of its useful life, due to the quick obsolescence of older technology. It would be inaccurate to assume a computer would incur the same depreciation expense over its entire useful life.
Understanding Salvage Value in Straight-Line Depreciation Formula
The business expects the machine to produce 100,000 units over its useful life. Many accountants use a simple, easy-to-use method called the straight-line basis. This method spreads out the depreciation equally over each accounting period. Unlike more complex methodologies, such as double declining balance, this straight line depreciation method uses only three variables to calculate the amount of depreciation each accounting period. Companies use depreciation for physical assets, and amortization for intangible assets such as patents and software.

Straight Line Depreciation: What is it and how do you use the straight-line depreciation formula
Once straight line depreciation charge is determined, it is not revised subsequently. Depreciation already charged in prior periods is not revised in case of a revision in the depreciation charge due to a change in estimates. A fixed asset having a useful life of 3 years is purchased on 1 January 2013. The depreciation of an asset under the straight-line depreciation method is constant per year. According to the straight-line method of depreciation, your wood chipper will depreciate $2,400 every year. Now that you know the difference between the depreciation models, let’s see the straight-line depreciation method being used in real-world situations.
