Depreciation with fixed-declining balance

You can calculate the depreciation of an asset by using the fixed-declining balance method (db) that computes the depreciation at a fixed rate.

This function takes the following arguments:

Cost – The original cost of the asset.
Salvage – The value at the end of the depreciation (also known as the salvage value of the asset).
Number of periods – The number of periods over which the asset is being depreciated, also known as the useful life of the asset.
Period – The period to calculate asset depreciation. Use the same unit measure as provided for the number of periods.
Number of months in the first year – Use this argument to provide a value between 1 and 12 for the first year of asset depreciation.
