Depreciation of fixed assets is an accounting transaction that all companies have to go through, including yours.
Depreciation can be used for a wide variety of intangible assets, this includes: offices, IT equipment, software, tools, and company vehicles. Regardless of your sector of activity, you will need tangible and intangible assets to run your business smoothly. And, it is essential for you to recognize the value of your fixed assets and their depreciation over the years.
Here is a complete guide to depreciation in accounting and how you calculate it.
Then, by following our example of a depreciation schedule and using accounting software, you will be able to make your own.
Depreciation of fixed assets is an accounting term that is used to represent how much of an asset’s value has been used up over time. Depreciation is, therefore, a calculated expense, which leads to a decrease in earnings.
Depreciation can be related to:
Why is depreciation important in accounting?
Depreciation is used to spread a loss in value over each accounting period. And, by using it, you will be able to anticipate the purchase of a new asset, when the optimal working conditions of the previous one has passed.
Here are some of the main types of depreciation you can use:
The straight-line method is the most basic way to record depreciation.
Straight-line depreciation determines a depreciation expense, that you will pay in equal annual instalments until the entire asset is depreciated to its salvage value.
👉 For example, if an asset is depreciated over 10 years, you will have an annual expense of 10% of the purchase value of the said asset.
The declining balance method is an accelerated depreciation method. This means that assets will depreciate by the same amount however it will be expensed higher in early years of its useful life while the depreciation expense will be lower in the later years of as compared to the straight-line method of depreciation.
Since an assets’ value is higher in the first few years, the declining balance method uses a higher depreciation rate during these years. Then, it declines slightly more in each following year.
What is the advantage of using this method?
Small businesses can use the declining balance method to deduct larger amounts at the beginning of their activity, thus paying less tax and building up more cash reserves.
The double-declining balance (DDB) method is an accelerated depreciation method similar to the one listed previously.
However, the uniqueness of this method is that asset value is depreciated at twice the rate it is done in the straight-line method.
How to determine the depreciation period of a fixed asset?
The depreciation period of a fixed asset must correspond to the life expectancy or useful lifespan of the said asset. This has to take into consideration:
Here are a few examples of depreciation periods:
Type of asset | Depreciation period |
---|---|
Vehicle | 4 to 5 years |
Office equipment | 5 to 10 years |
Commercial buildings | 20 to 50 years |
Industrial buildings | 20 years |
Warehouses | 20 years |
Tools | 5 to 10 years |
Computers | 3 to 5 years |
Software | 1 to 3 years |
Furniture | 10 years |
The depreciation period will now allow us to calculate the depreciation rate of the asset.
Calculation of the straight-line depreciation rate
Depreciation rate = (1 / useful life)
👉 Example:
A car has a depreciation period of 5 years. Its depreciation rate will be : 1 / 5 = 0.20
The depreciable base is the amount used to calculate annuity depreciation. It corresponds to the gross acquisition value of the asset.
This may correspond to:
We will now use the depreciable base and the depreciation rate to calculate annual depreciation.
Calculation of annual depreciation
Annual depreciation = Depreciation rate x Depreciable base
👉Example
The depreciable base for the car stated in the previous example corresponds to its purchase price, which is £12,000. Therefore, its annual depreciation will be: 0.20 x 12,000 = $2,400
If your business acquired and started to use the asset on the first day of the fiscal year, there is no need to revise the calculation of the first and last annuities.
On the other hand, if the asset was put into service during the fiscal year, this will have an impact on the depreciation annuity for the first and last year. And, therefore, a pro-rata temporis adjustment should be made.
Calculation of the first and last year's annuity
Depreciation rate x (number of days used/360) x Depreciable basis
👉Example
The car is put into service on the 01/06/N. It will therefore only be used for 210 days out of 360 in year N, and for 150 days in year N+5.
Calculation of the first annuity: 0.20 x (210/360) x 12,000 = $1,400
Calculation of the last annuity: 0.20 x (150/360) x 12,000 = $1,000
Data for the example :
Year | Calculation | Depreciation | Accumulated depreciation | Net book value (NBV) |
---|---|---|---|---|
N | 3000 x 0.25 x (275/360) | 572. 92 | 572.92 | 2427.08 |
N+1 | 3000 x 0.25 | 750 | 1322.92 | 1677.08 |
N+2 | 3000 x 0.25 | 750 | 2072.92 | 927.08 |
N+3 | 3000 x 0.25 | 750 | 2822.92 | 177.08 |
N+4 | 3000 x 0.25 x (85/360) | 177.08 | 3000 | 0 |
If you can use an Excel table for your accounting, using an accounting software has many benefits such as saving time, minimizing the risk of error and the certainty of being in compliance with the laws in force.
