Bound the allocation before choosing a method
Useful life estimates how long the asset will serve this entity. Inspect physical wear, expected use, capacity needs, technology, maintenance, replacement plans, contracts, and legal limits. The asset's possible physical existence does not override an earlier economic or legal limit.
Salvage value estimates what the entity expects to receive at the end of that service period, less supported disposal costs. It reduces the amount allocated to depreciation. A zero estimate can be reasonable, but zero is still an estimate that needs evidence.
Keep estimate effects visible
A longer useful life usually lowers periodic expense and raises carrying amount in earlier periods. A higher salvage value has a similar timing effect because less cost is allocated. Neither change creates cash or changes the original asset cost.
ASC 360-10-35-4 requires systematic and rational cost allocation over expected useful life. It does not select a life or salvage amount for a particular asset. Preserve the information available at the estimate date and apply later changes under the separate estimate-change analysis.
Exit check
For one asset, identify the earliest physical, economic, or legal service limit. Then estimate net salvage from the expected disposal channel and show how each input changes depreciable amount or periodic allocation.
