Geary Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $691,200 is estimated to result in $230,400 in annual pretax cost savings. The press falls in the MACRS five-year class (MACRS Table), and it will have a salvage value at the end of the project of $100,800. The press also requires an initial investment in spare parts inventory of $28,800, along with an additional $4,320 in inventory for each succeeding year of the project. Required : If the shop's tax rate is 34 percent and its discount rate is 10 percent, what is the NPV for this project?
