An asset value worth 300000
has a salvage value of 10000
at time = 10.
Calculate the depreciation charge at time 3
using the Straight Line Method

## Calculate Depreciation

 Dt  = Asset Value - Salvage Value N

 D3  = 300000 - 10000 10

 D3  = 290000 10

D3  =  29000

## Excel or Google Sheets formula:

=SLN(300000,10000,10)

## Calculate Book Value

B3 = (1-T/N) * A + S * T / N
B3 = (1 - 3/10) * 300000 + (10000 * 3)/10
B3 = (1 - 0.3) * 300000 + 30000/10
B3 = 0.7 * 300000 + 3000
B3 = 210000 + 3000
B3 = 213000

book value
the value of an asset according to its balance sheet account balance
depreciation
