# How to Calculate Straight Line Depreciation: Step-By-Step

Tuesday, 24 May, 2022 For example, office desktops, chairs, tables, and copiers are often used together. Hence, it’s sensible to depreciate them as a group instead of depreciating them individually.

For each accounting period, or year, the coffee shop would depreciate the espresso machine by \$600. As the asset approaches the end of its useful life, it will eventually depreciate to its salvage value once the end of its useful life is reached. The straight line depreciation method calculates the computer will depreciate \$200 every year. A significant change How To Calculate Straight Line Depreciation in the estimated salvage value or estimated useful life will be reported in the current and remaining accounting years of the asset’s useful life. For financial statements to be relevant for their users, the financial statements must be distributed soon after the accounting period ends. To achieve this requirement, accountants must estimate some amounts.

We will illustrate the details of depreciation, and specifically the straight-line depreciation method, with the following example. Our calculator measures asset lifespan in years, but you can switch to another time period if that’s more useful to you. Note that the straight depreciation calculations should always start with 1. To convert this from annual to monthly depreciation, divide this result by 12. The profit or loss on the sale of assets can be easily determined. It can be observed in the above graph, that the depreciation amount remains constant over a period of time and only the written down value of the asset decreases due to depreciation charged . The depreciation so calculated is to be charged over the life and debited to profit and loss account.

Since these business assets are often used on a daily basis, they tend to wear down over time. Owning a business requires constantly monitoring a variety of assets. Some assets wear out over the years and begin losing their value; for example, computers, tools, equipment, vehicles and buildings can depreciate over time and must be repaired or replaced.

At the same time, an accountant might purchase a similar computer and estimate that it will be useful in the accounting business for 4 years. Both the design engineer’s estimated useful life of 2 years and the accountant’s estimated useful life of 4 years are correct . When the asset’s book value is equal to the asset’s estimated salvage value, the depreciation entries will stop. If the asset continues in use, there will be \$0 depreciation expense in each of the subsequent years.

### How is straight-line depreciation calculated?

To calculate straight-line depreciation, you need to know three pieces of information about your asset: purchase price or cost, salvage value at the end of its useful life, and estimated number of years that the asset will be in service. Then you can use this formula to calculate straight-line depreciation: Depreciation = ( 1/ Estimated Useful Life) * Purchase Price or Cost

The next step in the calculation is simple, but you have to subtract the salvage value. Depreciation expense is the recognition of the reduction of value of an asset over its useful life. Multiple methods of accounting for depreciation expense exist, but the straight-line method is the most commonly used. In this article, we covered the different methods used to calculate depreciation https://www.wave-accounting.net/ expense, and went through a specific example of a finance lease with straight-line depreciation expense. Therefore, we allocate \$4,500 of the cost to depreciation expense every year. Our depreciation charges go to accumulated depreciation, which offsets the cost account of the fixed asset on the balance sheet. The depreciation rate is the rate an asset is depreciated each period.

## Straight Line Depreciation Method Examples

It is the easiest and simplest method of depreciation, where the asset’s cost is depreciated uniformly over its useful life. Because Sara’s copier’s useful life is five years, she would divide 1 into 5 in order to determine its annual depreciation rate. While the purchase price of an asset is known, one must make assumptions regarding the salvage value and useful life. These numbers can be arrived at in several ways, but getting them wrong could be costly. Also, a straight line basis assumes that an asset’s value declines at a steady and unchanging rate. This may not be true for all assets, in which case a different method should be used. Straight line basis is a method of calculating depreciation and amortization.

• Companies might select the diminishing balance method for a tech asset whose company releases updated models every 10 years instead of every five.
• The calculations required to create an amortization schedule for a finance lease can be complex to manage and track within Excel.
• These accounts have credit balance (when an asset has a credit balance, it’s like it has a ‘negative’ balance) meaning that they decrease the value of your assets as they increase.
