The VDB function calculates the depreciation of an asset for any period you specify, including partial periods, using the double-declining balance method or some other method you specify. VDB stands for variable declining balance.

VDB takes 5 required arguments and 2 optional arguments:

Syntax: VDB(cost, salvage, life, start_period, end_period, [factor], [no_switch])

#1)
Using the VDB function:
#2)
The arguments for the VDB function are:
Argument Required? Description
cost Required The initial cost of the asset.
salvage Required The value at the end of the depreciation (the salvage value of the asset). This value can be 0.
life Required The number of periods over which the asset is being depreciated (the useful life of the asset).
start_period Required The starting period for which you want to calculate the depreciation. Start_period must use the same units as life.
end_period Required The ending period for which you want to calculate the depreciation. End_period must use the same units as life.
factor Optional The rate at which the balance declines. If factor is omitted, it is assumed to be 2 (the double-declining balance method). Change factor if you do not want to use the double-declining balance method. For a description of the double-declining balance method, see @Html.ActionLink("DDB", "DDB")
no_switch Optional A logical value specifying whether to switch to straight-line depreciation when depreciation is greater than the declining balance calculation.
If no_switch is TRUE, Excel does not switch to straight-line depreciation even when the depreciation is greater than the declining balance calculation.
If no_switch is FALSE or omitted, Excel switches to straight-line depreciation when depreciation is greater than the declining balance calculation.

Summary

The VDB function calculates the depreciation of an asset for any period you specify, including partial periods, using the double-declining balance method or some other method you specify. VDB stands for variable declining balance.
