Describe concept of composite depreciation.



Composite depreciation claims depreciation expenses by depreciates group of related assets into single entity than individual. Composite depreciation is the application of straight-line depreciation. If the asset is sold, then account entry is debited to cash and credited to fixed asset. The difference between original cost and sold cost is debited to accumulated depreciation. In composite method, no loss or no gain on sale of fixed asset is recognized.

Steps to calculate composite depreciation are as follows −

  • Accumulation of total depreciation cost of assets.
  • Allocate single useful life for asset group.
  • Yearly depreciation = useful life/ total depreciation.
  • Document the depreciation.

Example

  • Calculate depreciation using composite depreciation, the data is given below.
Asset Cost (Rs.) Residual value (Rs.) Lifespan (years)
Asset – 1 10000 2000 8
Asset – 2 25000 4000 7
Asset – 3 5000 500 3
Asset – 4 80000
10

Solution

The solution is as follows −

Asset Cost (Rs.) Residual value (Rs.) Depreciation cost (Rs.) Lifespan (years) Deprecation (Rs.)
Asset – 1 10000 2000 10000 – 2000 = 8000 8 8000/8 = 1000
Asset – 2 25000 4000 25000 – 4000 = 21000 7 21000/7 = 3000
Asset – 3 5000 500 5000 – 500 = 4500 3 4500/3 = 1500
Asset – 4 88000
88000 – 0 = 88000 10 88000/80 = 1100
Total 128000


6600

Group depreciation = depreciation / total cost

                    = 6600 / 128000

                    = 5.16%

Average useful life = 1/group depreciation

                    = 1/5.16%

                    = 19.38 years
