From Apache OpenOffice Wiki
AMORLINC
Returns depreciation for a period using linear depreciation (French system).
This function is only available if the Analysis AddIn is installed.
Syntax:
AMORLINC(cost; purchase_date; first_period_end; salvage; period; rate; basis)
- cost: the acquisition cost.
- purchase_date: the date of acquisition.
- first_period_end: the end date of the first depreciation period.
- salvage: the salvage value at the end of life.
- period: the period for which to calculate depreciation. 0 is the initial period (from purchase_date to first_period_end.
- rate: the rate of depreciation.
- basis: is chosen from a list of options and indicates how the year is to be calculated. Defaults to 0 if omitted.
- 0 - US method (NASD), 12 months of 30 days each
- 1 - Exact number of days in months, exact number of days in year
- 2 - Exact number of days in month, year has 360 days
- 3 - Exact number of days in month, year has 365 days
- 4 - European method, 12 months of 30 days each
- Calculates the amount of depreciation for a period, using a linear depreciation method as in French accounting systems. The depreciation for the (possibly partial) first period is calculated proportionately.
- The life time t of the asset is 1/rate.
- The depreciation in the initial period 0 (the period (from purchase_date to first_period_end) is given by:
- cost*rate*YEARFRAC(purchase_date;first_period_end;basis).
- The depreciation in subsequent whole periods is given by:
- cost*rate.
- In the final (fractional) period of the life time, the depreciation reduces the remaining book value of the asset to salvage; in other words it is:
- cost - salvage - total_depreciation_charged_so_far.
- AMORLINC returns 0 after this.
Example:
AMORLINC(1000; "2004-02-01"; "2004-12-31"; 10; 8; 0.1; 1)
- returns 100.
