Tanaka Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $431,000 is estimated to result in $162,000 in annual pretax cost savings. The press falls in the MACRS five-year class (MACRS schedule) and it will have a salvage value at the end of the project of $63,000. The press also requires an initial investment in spare parts inventory of $16,800, along with an additional $3,800 in inventory for each succeeding year of the project. The shop’s tax rate is 23 percent and its discount rate is 10 percent. Calculate the project's NPV.
Note: Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.
