Excel Amordegrc Function Example

In the following example spreadsheet, the Excel Amordegrc function is used to calculate the depreciation of an asset during the first period. The asset was purchased on 01-Jan-2015, at a cost of €150 and the first period ends on 30-Sep-2015. The asset depreciates at a rate of 20% per year and has a salvage value of €20. The European 30/360 day count basis is used.

  A B
1 Purchase Date: 01-Jan-2015
2 First Period Date: 30-Sep-2015
3 =AMORDEGRC( 150, B1, B2, 20, 1, 20%, 4 )

The above Amordegrc function returns the value 42.

I.e. the asset depreciates by €42.00 during the first period.

Note that, as recommended, the date arguments have been supplied to the Amordegrc function as references to cells containing dates.
