The total dollar amount of the expense is the same, regardless of the method you choose. An asset’s initial cost and useful life are also the same using any method. The double-declining balance and the units-of-production method are two other frequently used depreciation methods. The depreciation journal entry is an adjusting entry, which is the entries you’ll make before running an adjusted trial balance. We need to ensure the creation of a contra asset account via the chart of accounts for accumulated depreciation before recording a journal entry.
Remember to adjust the depreciation expense downwards when an asset has been acquired or disposed off during the accounting period to avoid charging depreciation for the time the asset was not available for use. 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. An alternative to straight-line depreciation is the declining balance method, where the value of the asset is reduced by a percentage rather than a fixed amount.

As seen in the previous section, the straight-line depreciation method depreciates the value of an asset gradually, and linearly, over the years it is used. Here, each year will assign the same amount of percentage of the initial cost of the asset. Equal expenses are allocated to every unit and therefore, the calculation is done based on the output capability of the asset instead of the time in years. While there are various methods to calculate depreciation, three of them are more commonly used. The most important difference between this formula and other common depreciation formulas is the denominator.
The main differences between depreciation and straight-line method
It is calculated by simply dividing the cost of straight line formula accounting an asset, less its salvage value, by the useful life of the asset. Alternatively, depreciation expense for a period can be calculated by dividing the depreciable amount by the number of time periods. The depreciation expense worked out under this method would always correspond to the time unit used for expressing useful life, i.e. useful life in months must be used to work out monthly depreciation.
Units-of-production method
By using this formula, you can calculate when you will need to replace an asset and prepare for that expense. Below is a break down of subject weightings in the FMVA® financial analyst program. As you can see there is a heavy focus on financial modeling, finance, Excel, business valuation, budgeting/forecasting, PowerPoint presentations, accounting and business strategy. The asset account category includes intangible assets, which are not physical assets.

This account accumulates the depreciation posted each year, and each asset has a unique accumulated depreciation account. This method calculates annual depreciation based on the percentage of total units produced in a year. Let’s assume that a business buys a machine with a $50,000 purchase price and a $10,000 salvage amount. The business’s use of the machine fluctuates greatly, according to production levels.
Due to its simplicity, the straight-line method is the most common depreciation method. Where an asset’s productivity declines over time, it might be more appropriate to use any accelerated depreciation methods. The total depreciation over the asset’s useful life is $40,000, and the machine produces 100,000 units. The amount of expense posted to the income statement may increase or decrease over time. The straight-line method of depreciation isn’t the only way businesses can calculate the value of their depreciable assets.
What is the approximate value of your cash savings and other investments?
Amortisation expenses are used to post a decline in the value of these assets. The asset’s cost subtracted from the salvage value of the asset is the depreciable base. Finally, the depreciable base is divided by the number of years of useful life.
As seen from the above table – At the end of 8 years, i.e., after its useful life is over, the machine has depreciated to its salvage value. Lastly, let’s pretend you just bought property to build a new storefront for your bakery. You installed a fence around the entire plot of land, which falls under the 15-year property life. The initial cost of the fence was $25,000, and you think you can scrap the wood for $3,000 at the end of its useful life. Next, you’ll estimate the cost of the salvage value by considering how much the product will be worth at the end of its useful life span. Now that you know what straight-line depreciation is and why it’s important, let’s look at how to calculate it.
Since an amount equal to the residual value can be recovered by selling the asset or from its alternative use, only the difference between the cost and the residual value is depreciated. Useful life of a fixed asset represents the number of accounting periods within which the asset is expected to generate economic benefits. In addition to straight line depreciation, there are also other methods of calculating depreciation of an asset. Different methods of asset depreciation are used to more accurately reflect the depreciation and current value of an asset.
How to calculate the depreciation per unit
Asset depreciation is a valuable tax write-off for businesses, and the straight-line method simplifies its calculation, making preparing tax time more manageable. Deducting a portion of an asset’s cost each year, you can potentially reduce your taxable income and lower your tax bill. You can use this method to anticipate the cost and value of assets like land, vehicles and machinery. While the upfront cost of these items can be shocking, calculating depreciation can actually save you money, thanks to IRS tax guidelines.
It is the easiest and simplest method of depreciation, where the asset’s cost is depreciated uniformly over its useful life. This straight line method for depreciation helps in allocating or spreading the cost throughout the life in order to find out what should be the probable worth of it after a time period. This is a very easy and involves less complex calculation, which makes it comprehensible for everyone.
This technique is used when the companies utilize the asset in its initial years as the asset is more likely to provide better utility in these years. The straight-line method of depreciation can be used to depreciate almost any type of tangible assets such as property, furniture, computers, and equipment. Depreciation already charged in prior periods is not revised in case of a revision in the depreciation charge due to a change in estimates.
Step 2: Determine the asset’s life span and salvage value
One convention that companies embrace is referred to as depreciation and amortization. Accountants commonly use the straight-line basis method to determine this amount. This number will show you how much money the asset is ultimately worth while calculating its depreciation. By estimating depreciation, companies can spread the cost of an asset over several years. The straight-line depreciation method is a simple and reliable way small business owners can calculate depreciation. The straight-line depreciation method is important because you can use the formula to determine how much value an asset loses over time.
