Final answer:
The relevant factors in computing depreciation include cost, residual value, useful life, and depreciation method.
Step-by-step explanation:
The relevant factors in computing depreciation include cost, residual value, useful life, and depreciation method. The cost represents the initial cost of the asset, while the residual value is the estimated value at the end of its useful life. Useful life refers to the expected period of time the asset will be used, and the depreciation method determines how the cost is allocated over time.
