Where the arguments are as follows:

cost - The cost of the asset
date_purchased - The date of purchase of the asset
first_period - The date of the end of the first period
salvage - The salvage value, at the end of the lifetime of the asset
period - The number of the period over which the depreciation is to be calculated
rate - The asset's rate of depreciation
[basis] - An optional integer argument which specifies the financial day count basis to be is used. This may be any of the following values:
Basis Day Count Basis

1 actual/actual
2 actual/360
3 actual/365
4 European 30/360
A detailed description of the financial day count basis rules is provided on the Wikipedia Day Count Convention page

Note that the date arguments should be entered into the function as either:

Warning:

- If you attempt to input the dates as text, they may be misinterpreted, due to the date system and date interpretation settings on your computer.
- Although dates can be entered as serial numbers, this is not advised, as date serial numbering varies across different computer systems.


Excel Amordegrc Function Example

In the following example, the Excel Amordegrc function is used to calculate the depreciation of an asset during the first period. The asset was purchased on 01-Jan-2011, at a cost of €150 and the first period ends on 30-Sep-2011. The asset depreciates at a rate of 20% per year and has a salvage value of €20. The European day count basis is used.

  A B
1 Purchase Date: 01-Jan-2011
2 First Period Date: 30-Sep-2011
3 =AMORDEGRC( 150, B1, B2, 20, 1, 20%, 4 )

The function returns the value 42.

- i.e. the asset depreciates by €42.00 during the first period.

Note that, as recommended by Microsoft, the date arguments have been input to the above function as references to cells containing dates.
