How it's calculated

Straight-line: (cost − salvage) ÷ life
Declining balance: opening book value × rate (double-declining rate = 2 ÷ life)
Sum-of-years' digits: (cost − salvage) × years left ÷ (n(n + 1) ÷ 2)

Straight-line spreads the cost evenly; declining balance and sum-of-years' digits put more of it in the early years, which suits assets that lose value fast. Tax authorities often prescribe their own methods and lives, so use this for accounting estimates and check the rules for a tax return.
