The Mathematical Formula & Variables

Straight-Line = (Cost - Salvage) / Useful Life

Step-by-Step Worked Example

Scenario: $20,000 machine, $2,000 salvage, 5-year life.

  1. Depreciable base = $20,000 - $2,000 = $18,000.
  2. Annual straight-line = $18,000 / 5 = $3,600/year.
  3. Double declining (40% rate) Year 1 = $20,000 * 0.40 = $8,000.

Result: $3,600/yr (Straight-Line) or $8,000 (DDB)

Frequently Asked Questions
