<p>The <b>DB</b> function is one of the financial functions. It is used to calculate the depreciation of an asset for a specified accounting period using the fixed-declining balance method.</p>
<pstyle="text-indent: 50px;"><b><em>cost</em></b> is the cost of the asset.</p>
<pstyle="text-indent: 50px;"><b><em>salvage</em></b> is the salvage value of the asset at the end of its lifetime.</p>
<pstyle="text-indent: 50px;"><b><em>life</em></b> is the total number of the periods within the asset lifetime.</p>
<pstyle="text-indent: 50px;"><b><em>period</em></b> is the period you wish to calculate depreciation for. The value must be expressed in the same units as <em>life</em>.</p>
<pstyle="text-indent: 50px;"><b><em>month</em></b> is the number of months in the first year. It is an optional argument. If it is omitted, the function will assume <b><em>month</em></b> to be 12.</p>
<p>The values can be entered manually or included into the cell you make reference to.</p>
