j : depreciation charge for the j th year
RDV j : remaining depreciable value at the
end of j th year
I % : depreciation factor
Press 3(DEPREC) from the Financial 2 screen to display the following input screen for
depreciation calculation.
6( g) 3(DEPREC)
n ............ useful life
I % ......... depreciation ratio in the case of the fixed percent (FP) method, depreciation factor in
the case of the declining balance (DB) method
P V ......... original cost (basis)
F V ......... residual book value
j ............. year for calculation of depreciation cost
Y −1 ........ number of months in the first year of depreciation
