Asset Details

How It Works

Straight-Line (SL)

Spreads the depreciable cost evenly over the asset's life.
Annual Depreciation = (Cost − Salvage Value) ÷ Useful Life

Declining Balance (DB) / Double Declining Balance (DDB)

Applies a fixed rate to the remaining book value each year, resulting in higher deductions early.
Rate = Multiplier ÷ Useful Life  |  Depr. = Book Value × Rate
DDB uses a 2× multiplier. Book value never falls below salvage value.

Sum-of-Years-Digits (SYD)

Front-loads depreciation using a fraction based on remaining life over the sum of all years' digits.
SYD = n(n+1)÷2  |  Depr. = (Remaining Life ÷ SYD) × Depreciable Base

Depreciable Base

All methods start from the depreciable base = Cost − Salvage Value, ensuring the asset is never written below its residual value.
