How the calculation works

Straight line spreads cost minus salvage evenly; the other methods take more in the early years.

A worked example
Cost
10,000
Salvage value
1,000
Life (years)
5

Step by step

  1. Cost − Salvage value = 10,000 − 1,000 = 9,000
  2. Straight line: 9,000 ÷ 5 = 1,800 · 8,200 → 6,400 → 4,600 → 2,800 → 1,000
  3. Sum of years' digits 1: 9,000 × 5 ÷ 15 = 3,000 → 7,000
  4. Sum of years' digits 2: 9,000 × 4 ÷ 15 = 2,400 → 4,600
  5. Sum of years' digits 3: 9,000 × 3 ÷ 15 = 1,800 → 2,800
  6. Sum of years' digits 4: 9,000 × 2 ÷ 15 = 1,200 → 1,600
  7. Sum of years' digits 5: 9,000 × 1 ÷ 15 = 600 → 1,000

Salvage value is what the asset should be worth at the end of its life. The schedule uses whole years from month 1 and is not a tax schedule.
