The depreciation in a given year can be expressed by the following equation: Dn ¼ IC À S À TC N (2:1) where Dn is the depreciation in year n, IC the initial cost ($), S the salvage value ($), TC the tire and track costs ($), N the useful life (years), and D1 ¼ D2 ¼ Á Á Á ¼ Dn . 2 Sum-of-Years’-Digits Depreciation The sum-of-years’-digits depreciation method tries to model depreciation assuming that it is not a straight line. The actual market value of a piece of equipment after 1 year is less than the amount predicted by the straight-line method.
