Engineering Economy question!
Your company purchased an asset that costs $235,000, and had an expected salvage value of $25,000. The asset has a 15-year depreciation life, and it is kept for 15 years and then sold for $25,000. Use the SL, SYD methods to the book value and depreciation at the end of each year.
SL method:
Depreciation expense in each year = (Cost – Salvage value) / Life years
= (235000 – 25000) / 15
= 210000 / 15
= 14000
Ending book value = Beginning book value – Depreciation expense
Ending book value of one year would be the beginning book value of coming year.

SYD method:
Sum of years = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 = 120
Depreciation base = Cost – Salvage value = 235000 – 25000 = 210000
Depreciation fraction = Remaining life years / Sum of years
Depreciation expense in each year = Depreciation base × Depreciation fraction.
Book value = Previous book value – Depreciation expense
