If your company has expensive equipment, tools or machinery, you should consider whether depreciating these assets would have financial advantages for you. For example, if you depreciate assets, you can generate tax deductions and defer tax payments for your company. This could amount to savings of thousands of dollars. Additionally, recording the depreciation of your fixed assets is important for preparing accurate balance sheets and tax reports.
Below, we explain how depreciation works, why companies depreciate their assets, and the most common methods used to calculate depreciation.
To calculate depreciation for your fixed assets, you must track the following information:
Purchase date or date in service
When was the asset purchased or put into service?
Cost
How much did the asset cost?
Useful life
How long (in years) do you expect the asset to be useful?
Salvage value
How much can you re-sell the asset for when it reaches the end of its useful life?
What is Depreciation?
Depreciation is an accounting method used to allocate the cost of a fixed asset over its lifetime. This allows a company to write off the asset's value over its useful life, rather than all at once during the year it is purchased.
Deprecation represents an asset’s value after being used for some time and ties the cost of using an asset with the benefit gained over its useful life. By depreciating assets, a company can spread out the cost of the asset and tie depreciation expenses to related revenues in the same reporting period. The depreciation charges reduce the company’s taxable income, which then decreases its tax liability.
Let’s say a company has purchased a machine for $50,000. The machine has a ten-year useful life and can be scrapped at the end of its useful life for $10,000 (its salvage value).
When the machine is purchased the company has two options: it can expense the entire cost of the machine in year one, or it can write off the machine’s value over its 10-year useful life. Expensing only a portion of the machine’s cost can boost net income, which is why this option is preferred by most business owners.
Let’s assume the company decides to depreciate the machine. The company’s accountant calculates the depreciation expense as the difference between the machine’s cost and its salvage value, divided by its lifespan: ($50,000 - $10,000) / 10. This amounts to a depreciation expense of $4,000 each year. This depreciation expense is a tax deduction.
The accountant is able to expense $4,000 against net income that first year, and will continue to expense $4,000 for that machine for each year of its useful life until it reaches its $10,000 salvage value.
What are the Most Common Methods of Depreciation?
There are many different methods that can be used to depreciate fixed assets. Some commonly-used methods include straight-line, declining balance, and sum-of the years’ digits. Companies may choose which depreciation method to use based on how much depreciation expenses they would like to charge each year against their revenue for that year. Some assets naturally depreciate faster at the beinning of their life than at the end, and it may be preferrable for their depreciation schedule to reflect that fact.
Straight-Line Depreciation
The straight-line method is the most basic way to record depreciation. The straight-line method calculates depreciation by dividing the depreciable amount of the asset (i.e., the cost of the asset minus its salvage value) by the number of years of its useful life. For example, if you purchase a server for $5,000 that has a salvage value of $1,000, then its depreciable amount is $4,000. If you estimate that the server will have a lifespan of five years, then you would divide the depreciable amount by its lifespan: $4,000 / 5. This amounts to $800 in depreciation each year and a depreciation rate of 20%.

Declining Balance
Declining balance is an accelerated depreciation method. With this method, equipment is depreciated at its straight-line depreciation rate, multiplied by its remaining depreciable amount each year. This results in a higher depreciation expense amount in the earlier life of the asset, with the amount declining in each subsequent year. Using this method more accurately reflects that many assets depreciate more quickly in their first years of life.
Declining balance is combined with a factor or multiplier that determines how much faster assets start depreciating compared to the straight-line method. The most common factors are 2 and 4 (i.e., twice as fast or four times as fast). When the factor is 2, the method is referred to as double-declining balance.
For example, if we use the $5,000 server from above with a straight-line depreciation rate of 20% over a five-year lifespan, then its double-declining depreciation schedule would look like this:

Double declining balance depreciation schedule
There are two important things to note about declining-balance depreciation:
The rate is multiplied by the opening book value, not the total depreciable value like it is with the straight-line method
Depreciation stops when the closing book value has reached the salvage value, even if there is still time left on the depreciation schedule
Sum of the Years’ Digits
Sum of the years’ digits is another accelerated depreciation method. It can be thought of as a cross between the straight-line method and the declining balance method. In this method, the rate changes from year to year, but it is multiplied against the total depreciable value each time.
There are two steps to calculating the rate for sum of the years' digits depreciation:
Calculate the denominator, which is the same each year and equals the nth triangular number (i.e., sum of digits), where n is the length of the depreciation schedule. So, if the depreciation schedule is 5 years long, the denominator is 1 + 2 + 3 + 4 + 5 = 15, or n(n + 1) / 2.
Calculate the numerator for the specific year: 5 in year 1, 4 in year 2, all the way down to 1. The multiplier for the year is then the quotient of these two calculations: 5 / 15 for year 1, 4 / 15 for year 2, etc.
