Depreciation is calculated over the entire useful life of a fixed asset or an intangible asset. In accordance with Russian accounting rules, depreciation is calculated from the first month following the month the asset was acquired.

Depreciation is also calculated from the month, quarter, half-year, or the year following the month of asset acquisition for business or accounting purposes.

Parameters, such as the depreciation method and useful life, are determined for the depreciation group within the framework of the value model, and by default, are assigned to all assets that belong to this group. If necessary, however, the default depreciation profile of a fixed asset or inventory asset and its useful life can be changed.

Transactions that affect a depreciated asset also affect the useful life of the asset. The change history is recorded in the relevant journal. The depreciation calculation transaction is created from the first date of the period for which the depreciation is calculated.

Depreciation is not calculated during major repairs or temporary deactivation, during which time the Temporary closing-downstatus is assigned, but resumes when the asset is reactivated. Depreciation is calculated until the value of the asset is fully depreciated and the asset is assigned a closed or written-off status.
