What is a straight-line depreciation calculator?

A Straight-Line depreciation calculator is a useful tool for any company or individual who needs to calculate the depreciation of an asset over time.

Depreciation is the process of allocating an asset’s cost over its useful life, and it is a common practice used by businesses to account for asset costs in their financial statements.

The Straight-Line Depreciation Calculator is based on the straight-line method, which is the easiest and most common way to calculate depreciation. Under this method, the cost of an asset is spread out evenly over its useful life. 


The formula for calculating straight-line depreciation is as follows:

Depreciation = (Cost of Asset – Salvage Value) / Useful Life of Asset


A company purchases a machine for $200,000. The expected salvage value at the end of its useful life is $20,000 and the machine is expected to be used for 20 years. 

The annual straight-line depreciation for this machine would be:

Depreciation = ($200,000 – $20,000) / 20 years = $9,000 per year

How to use a straight-line depreciation calculator

It’s easy to use a straight-line depreciation calculator. Just put in the cost of the asset, its expected salvage value, and its useful life, and the calculator will figure out how much it will depreciate each year. 

The calculator can also be used to calculate accumulated depreciation over time, which can help businesses account for an asset’s loss in value over time.

When using a Straight-Line Depreciation Calculator, it’s important to think about how the asset will be used and the country’s or region’s accounting rules and tax laws.

Since the Straight-Line Depreciation Calculator uses a fixed method to figure out depreciation, it may not be right for all types of assets.

Some assets, like vehicles or equipment, may have a high rate of depreciation in the first few years and a lower rate in later years. In this case, a different method of depreciation would be better.
