What does Asset depreciation calculator do?

It helps you inspect or process this value and get a readable result quickly.

Is my input saved?

Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.

How is straight-line depreciation calculated?

Subtract salvage value from asset cost, then divide by useful life. Accumulated depreciation is annual depreciation multiplied by elapsed years, and book value is cost minus accumulated depreciation.

Why subtract salvage value first?

Salvage value is the estimated value left at the end of use. Straight-line depreciation usually spreads only the depreciable amount, which is cost minus salvage value.

Can this be used directly for accounting entries?

No. It is a formula-only estimate. Official useful life, salvage policy, tax treatment, and ledger entries should be reviewed against company policy, local rules, and professional advice.
