Depreciation A machine costing $210.000 with a four-year life and an estimated $20,000 residual value is installed at Apples headquarters in California on January 1. The factory manager estimates the machine will produce 475,000 units of product during its life. It actually produces the following units year 1, 121,400 year 2. 122.400 year 3. 119,600, and year 4, 118,200. The total number of units produced by the end of year 4 exceeds the original estimate this difference was not predicted. (The machine must not be depreciated below its estimated residual value) Depreciation A machine costing $210,000 with a four-year life and an estimated $20,000 residual value is installed at Apples headquarters in California on January 1.
