How it is calculated

  1. Straight-line: (cost − salvage) ÷ life, every year.
  2. Declining balance: book value × rate ÷ life, switching to straight-line when that is higher, never going below salvage.
  3. Sum of years’ digits: (cost − salvage) × remaining years ÷ (1 + 2 + … + life).

Example

A 10,000 asset, 1,000 salvage, 5 years, 200% declining balance: 4,000 in year 1, then 2,400, 1,440, 864 and 296. Total depreciation 9,000.

Good to know

  • Accounting depreciation, not a tax deduction: tax rules (US MACRS, other countries’ schedules) differ.
  • Full years only, with no first-year proration.
