Purchase Price of Machine Rs. 1,50,000, Installation Charges Rs. 50,000, Residual Value Rs. 81,920, Useful life 4 years, the amount of depreciation under WDV Method for the third year will be:
Here , formula for WDV is - deprecciation rate = 100 * (1-n√s/c)
where n = number of years , s = salvage value , c = cost of asset
=[1-4√40960/100000] * 100
= [1-4√0.4096] * 100
= [1-.80]*100
=.20*100
=20
1st year WDV = 200000*20% = 40000 = 200000-40000 = 160000
2nd Year WDV = 160000*20% = 160000-32000 = 128000
3rd Year WDV = 128000*20% = 25600
