Sum of First n Odd Numbers Formula, Proof and Examples

Similar to the double declining balance method, sum of years depreciation aims to depreciate a company’s assets at an accelerated rate. Companies may choose the SYD method as the practice will result in a larger depreciation tax shield in the first few years of the asset’s life. There are four allowable methods for calculating depreciation, and which one a company chooses to use depends on that company’s specific circumstances. Small businesses looking for the easiest approach might choose straight-line depreciation, which simply calculates the projected average yearly depreciation of an asset over its lifespan.

  • Still, it differs from straight-line depreciation, where the amount deducted is the same for each year of an asset’s useful life.

  • The SYD function is helpful to a financial analyst when building financial models or creating a fixed asset depreciation schedule for analysis.
  • An accelerated method that doubles the depreciation rate of the declining balance method, resulting in higher early-year depreciation.

Straight-line depreciation recognizes the same amount of depreciation each period over the useful life of the asset. On the other hand, accelerated depreciation methods recognize a larger percentage of the total depreciation in earlier periods. This has the tax advantage of allowing a larger depreciation deduction faster. The sum-of-the-years’-digits depreciation (SYD depreciation) is one method for calculating accelerated depreciation. However, the total amount of depreciation over an asset’s useful life should be the same regardless of which depreciation method is used. In other words, the difference is in the timing of when the same total amount of depreciation will be reported.

Calculating Depreciation Using the Declining Balance Method

The method is more appropriate than the more commonly-used straight-line depreciation if an asset depreciates more quickly or has greater production ca­pacity in its earlier years than it does as it ages. The total amount of depreciation is identical no matter which depreciation method is used – the choice of depreciation method only alters the timing of depreciation recognition. An asset’s productivity is highest in its early years and gradually decreases over time. This approach results in higher depreciation charges during the initial years. Depreciation calculations determine the portion of an asset’s cost that can be deducted in a given year. Or, it may be larger in earlier years and decline annually over the life of the asset.

Let’s go through an example using the four methods of depreciation described so far. Assume that our company has an asset with an initial cost of $50,000, a salvage value of $10,000, and a useful life of five years and 3,000 units, as shown in the screenshot below. Our job is to create a depreciation schedule for the asset using all four types of depreciation.

To figure out the depreciation expense of each year, we first need to calculate is the sum of the years digits. Since the useful life of the truck is four years, we need add all numbers that fall between 4 and zero to find the sum. For example, if an asset costs $1000 and has a salvage value of $200, its depreciation base is $800. For example, if an asset has a useful life of 5 years, the sum of its years’ digits will equal 15 (1 + 2 + 3 + 4 + 5).

Steps to achieve depreciation through the sum of the years’ method

Depreciation is an accounting method that companies use to apportion the cost of capital investments with long lives, such as real estate and machinery. Depreciation reduces the value of these assets on a company’s balance what is operating income operating income formula and ebitda vs operating income sheet. To illustrate SYD depreciation, assume that a service business purchases equipment at a cost of $160,000. This asset is expected to have a useful life of 5 years at which time it will be sold for $10,000.

How to Calculate Straight Line Depreciation

Total acquisition cost includes the purchase price, shipping costs, and any other costs undertaken to get an asset ready for use. The salvage value is simply the estimated value of an asset at the end of its useful life. It must be noted that the final depreciation expense equals the salvage value of the asset. An older deteriorated asset demands more repairs and maintenance charges. Therefore, a decreasing depreciation charge will help balance the cost of maintenance of the asset.

However, the company needs to properly allocate the cost so that the depreciation expense charged to the income statement matches the benefits that the company receives from the fixed assets. This is so that the recognition of the depreciation expense in the company’s account is properly in compliance with the matching principle of accounting. Before calculating how much depreciation is charged to each accounting period in Step 5, we first need to calculate the depreciation expense for each year of the asset life. The following example shows how you can work your way through each of the above steps to calculate depreciation using the sum of the years’ digits method.

This means that the total amount of depreciation will be $150,000 spread over the equipment’s useful life of 5 years. Suppose we want to calculate the depreciation for an asset with an initial cost of $300,000 and a salvage value of $5,000 after 10 years. The SYD function is helpful to a financial analyst when building financial models or creating a fixed asset depreciation schedule for analysis. In the second accounting period ending on 31 December 2021, 9 months out of the first year of the asset overlaps as well as 3 months out of the asset’s second year.
