Timescale Units | Formula to Calculate Depreciation per Period |
|---|---|
Monthly | (Acquisition Cost – Salvage Value) / (Depreciation Period * 12) |
Quarterly | (Acquisition Cost – Salvage Value) / (Depreciation Period * 4) |
Yearly | (Acquisition Cost – Salvage Value) / (Depreciation Period * 1) |
Net Book Value = Starting Book Value – Current Period Depreciation
Starting Book Value = Net Book Value of Previous Period
Starting Book Value of First Period = Acquisition Cost
