The Current Cost Accounting method assets are shown in the balance sheet on current replacement costs after allowing for depreciation. This will require an adjustment in depreciation too.

### Formula

Current year’s depreciation under CCA can be calculated with the help of following formula:

And,
Depreciation Adjustment = Current year’s depreciation on CCA – Depreciation on historical cost

### Example

A machine was purchased on 1.1.2014 at a cost of \$10,00,000 and its useful life was estimated to be 10 years. Its replacement cost was \$1,80,000 on 1.1.2019 and 20,00,000 on 31.12.2019. Calculate the amount of depreciation adjustment.

#### Solution

Current year’s depreciation (CCA method) = (1,80,000 + 20,00,000) / (2 x 10)
= \$1,90,000
Historical Depreciation = 10,00,000 / 10 = \$1,00,000
Depreciation Adjustment = Current year’s dep. on CCA – Historical dep.
= 1,90,000 – 1,00,000
= \$90,0000
