Final answer:
The formula for calculating revised annual depreciation assuming straight-line is (Cost - Accumulated Depreciation) / Useful Life. It takes into account the initial cost of the asset, subtracts the accumulated depreciation over time, and divides it by the useful life of the asset.
Step-by-step explanation:
The formula for calculating revised annual depreciation assuming straight-line is: (Cost - Accumulated Depreciation) / Useful Life.
This formula takes into account the initial cost of the asset, subtracts the accumulated depreciation over time, and divides it by the useful life of the asset.
For example, if the cost of an asset is $10,000, the accumulated depreciation is $2,000, and the useful life is 5 years, the revised annual depreciation would be:
(10,000 - 2,000) / 5 = $1,600
