B Co acquired a non-current asset on 1 January 20X2 for $80,000. It had no residual value and a useful life of 10 years. On 1 January 20X5 the total useful life was reviewed and revised to 7 years. What will be the depreciation charge for 20X5?
After 3 years’ depreciation (X2, X3 and X4) (3 x $8,000) the asset now has a carrying value of $80,000 – $24,000 = $56,000
If the TOTAL useful life is now reduced from 10 years to 7 years, and 3 of those 7 have already gone, then the remaining useful life is just 4 more years.
