The diminishing balance method achieves the same outcome as the double-declining balance method, but at a less aggressive pace. Companies might select the diminishing balance method for a tech asset whose company releases updated models every 10 years instead of every five. Not all assets are purchased conveniently at the beginning of the accounting year, which can make the calculation of depreciation more complicated. Depending on different accounting rules, depreciation on assets that begins in the middle of a fiscal year can be treated differently.

Straight line depreciation is the most commonly used and straightforward depreciation method for allocating the cost of a capital asset. It is calculated by simply dividing the cost of an asset, less its salvage value, by the useful life of the asset. There are many methods of distributing depreciation amount over its useful life.

Calculate Straight Line Depreciation

If you are calculating depreciation value for tax purposes, you should get the accurate, useful life figure from the Internal Revenue Agency (IRS). When keeping your company accounting records, straight line depreciation can be recorded on the depreciation expense account as debit and credit on the accumulated depreciation account. With straight line depreciation, the value of an asset is reduced consistently over each period until the salvage value is reached.

From buildings to machines, equipment and tools, every business will have one or more fixed assets likely susceptible to depreciate or wear out gradually over time. For example, with constant use, a piece of company machinery bought in 2015 would have depreciated by 2019. This method is useful because it is simple and can be applied on many kinds of long-term assets. However, this method does not show accurate difference in the usage of an asset and could be inappropriate for some depreciable assets. The depreciation expense in this kind of asset is not likely to be similar throughout its useful life as new technologies keep on changing.

However, this method uses assumed (guesswork) factors which is a major drawback in any calculation. In this method the production or initial costs of an asset are evenly spread during the course of its useful life span. This value is then divided by the number of years it is expected to be used and the value obtained is further subtracted from the second year on. When the value of an asset drops at a set rate over time, it is known as straight line depreciation. Estimated Useful Life of Asset is the estimated time or period that an asset is perceived to be useful and functional from the date of first use up to the day of termination of use or disposal.

However, the diminishing balance method is unique in that its value decreases by a fixed percentage amount. The salvage price is found by applying the depreciation percentage for the number of years of the asset’s life. The other popular methods used in calculating depreciation value are; Sum of years method or unit of production method and double declining balance method. In these situations, the declining balance method tends to be more accurate than the straight-line method at reflecting book value each year.

Straight Line Depreciation Formula Calculator

According to straight line depreciation, the company machinery will depreciate $500 every year. Use this calculator to calculate the simple straight line depreciation of assets. These classes include properties that depreciate over three, five, ten, fifteen, twenty, and twenty-five years. A Straight Line Depreciation Calculator fixed asset account is reduced when paired with accumulated depreciation as it is a contra asset account. The first step is to calculate the numerator – the purchase cost subtracted by the salvage value – but since the salvage value is zero, the numerator is equivalent to the purchase cost.

How do you calculate straight-line depreciation in Excel?

Our formula will =SLN(B2, B3, B4).

The formula returns the depreciation amount as Rs. 12667/- per year which will be continuously same for 15 years (or the life of our asset). You can also calculate the depreciation of an asset for a specified period using the fixed-declining balance method by using the DB Function.
