Depreciation Methods Explained

Straight Line (SL)

This method spreads depreciation evenly over the asset’s useful life.

Formula:

Annual Depreciation = (Cost − Salvage Value) ÷ Useful Life

Double Declining Balance (DDB)

This is an accelerated method where depreciation is higher in early years.

Formula:

Rate = (2 ÷ Useful Life)  
Depreciation = Rate × Book Value at Beginning of Year

Sum of Years’ Digits (SYD)

Another accelerated method based on the sum of year digits.

Formula:

SYD = n(n+1) ÷ 2  
Depreciation Year = (Remaining Life ÷ SYD) × (Cost − Salvage Value)

Example Depreciation Calculation

Cost: $10,000
Salvage Value: $2,000
Useful Life: 5 years

Straight Line:

(10,000 − 2,000) ÷ 5 = $1,600 depreciation per year
