Use this calculation when every balance, flow, and elapsed period follows the same accounting basis, currency, entity boundary, and reporting period. It is useful for a reproducible schedule or analytical cross-check, but the result should still reconcile to the ledger.

Cost

Original capitalized cost of the asset.

Accumulated depreciation

Accumulated depreciation through the disposal date; must not exceed cost.

Sale proceeds

Cash or consideration received on disposal; a negative value represents consideration paid to dispose.

The implemented rule is: Determine the gain or loss on disposing of a depreciable asset: book value as cost minus accumulated depreciation, then sale proceeds minus book value.^[1]

Book value

Net book value of the asset at disposal, cost less accumulated depreciation.

Gain or loss

Gain when positive or loss when negative on disposal, proceeds minus book value.

The calculator applies the stated arithmetic and does not decide whether a recognition method or classification is permitted under a particular accounting framework. Estimates, cutoff errors, seasonality, acquisition effects, inconsistent averages, and differing policies can make a mathematically correct result misleading.

Reconcile the inputs to the general ledger and supporting schedules. For reporting decisions, compare the result with the entity's accounting policy, applicable GAAP or IFRS guidance, prior-period disclosures, and an accountant's review.

• Useful Life Revision Calculator

  Compute revised annual straight-line depreciation after a useful-life estimate change: book value at revision minus revised salvage, divided by remaining years, applied prospectively.

• Units-of-Production Depreciation Rate Calculator

  Compute the units-of-production depreciation rate per unit as cost minus salvage value divided by estimated total units of output.
