The simplest depreciation schedule is straight line depreciation. Straight line depreciation depreciates an asset evenly across the assets life. For example, if an asset cost $1000 and has a useful life of 10 years, then its yearly depreciation is $1000/10=$100. You can also use the double declining balance method. This is a form of accelerated depreciation that prescribes twice an annual
. rate of depreciation twice that of the straight line method.
