Suppose we are thinking about replacing an old computer with a new one. The old one cost us $1,680,000; the new one will cost, $2,027,000. The new machine will be depreciated straight-line to zero over its five-year life. It will probably be worth about $450,000 after five years. The old computer is being depreciated at a rate of $360,000 per year. It will be completely written off in three years. If we don't replace it now, we will have to replace it in two years. We can sell it now for $558,000; in two years, it will probably be worth $162,000. The new machine will save us $378,000 per year in operating costs. The tax rate is 21 percent, and the discount rate is 12 percent.

Suppose we are thinking about replacing an old computer with a new one. The old one
cost us $1,680,000; the new one will cost, $2,027,000. The new machine will be
depreciated straight-line to zero over its five-year life. It will probably be worth about
$450,000 after five years.
The old computer is being depreciated at a rate of $360,000 per year. It will be
completely written off in three years. If we don't replace it now, we will have to replace it
in two years. We can sell it now for $558,000; in two years, it will probably be worth
$162,000. The new machine will save us $378,000 per year in operating costs. The tax
rate is 21 percent, and the discount rate is 12 percent.
