Accordingly, depreciation calculation by estimating residual value and change of this value that estimated on date of entry assets of a depreciation unit in useful life in accordance with “TAS 8 Accounting Policies, Changes in Accounting Estimates and Errors” are exemplified both according to cost and revaluation models by taking into fair value hierarchy. Thus, recommendations of how to apply depreciation methods with Turkish Accounting/Financial Reporting Standards framework are presented.
