# Depreciation Calculation Problem

Hello gurus,

I'm facing a problem of finding depreciation key in T-Code: AFAMA that have solution of depreciation calculation as following:

Depreciation cost = (Net Value - Scrap Value) / Asset's life time

Ex. Asset No. 3100000001 has cost $1000 with life time 5 years and the scrap value = $10. We start using this asset in 01.01.2011

So, the depreciation cost would be (1000 - 10) / 5 = 198

Right now, our system is not subtract scrap value in first year (Formula = 1000/5).

Any solution of subtracting scrap in first year before devided by year? (Average scrap in each year)

Please help

Thank you very much
