There are good reasons for using both of these methods, and the right one depends on the asset type in question. The straight-line depreciation method is the easiest to use, so it makes for simplified accounting calculations. Before you can calculate depreciation of any kind, you must first determine the useful life of the asset you wish to depreciate. In the formula above, the depreciation factor you choose will depend on how quickly you believe the asset will lose its value. The larger the factor, the more quickly the asset’s value will be depreciated in the beginning of its life. When usage is the key factor in calculating depreciation, use the units-of-production method.

To calculate the straight-line depreciation expense of this fixed asset, the company takes the purchase price of $100,000 minus the $30,000 salvage value to calculate a depreciable base of $70,000. This results in an annual depreciation expense over the next 10 years of $7,000. The straight line method of depreciation provides small business owners with a simple formula for depreciation. In setting up your small business accounting system, knowing your depreciation methods can help you choose the right method that matches the pattern of usage of your fixed assets.

Small and large businesses widely use straight line depreciation for its simplicity, accuracy, and functionality, but other methods of calculating an asset’s depreciation value exist. With straight line depreciation, the value of an asset is reduced consistently over each period until the salvage value is reached. Since we expect to sell the asset at its estimated salvage value, we won’t include that amount in depreciation. Let’s say, for instance, that a hypothetical company has just invested $1 million into long-term fixed assets.

Then, you divide $1,500 by five years, to reach an annual depreciation of $300. Enter the total cost to acquire the asset, or the adjusted basis, whichever is the lesser amount . If you are adjusting the depreciation schedule for over or retail accounting under-reporting depreciation in prior years, enter the remaining depreciable base. Plus, the calculator also calculates first and final year depreciation expenses in cases where the asset is placed in service for a partial first year.
