Purple Haze Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $503,820 is estimated to result in some amount of annual pretax cost savings. The press will have an aftertax salvage value at the end of the project of $85,630. The OCFs of the project during the 4 years are $170,654, $198,780, $179,754 and $169,541, respectively. The press also requires an initial investment in spare parts inventory of $27,634, along with an additional $2,508 in inventory for each succeeding year of the project. The shop's discount rate is 8 percent. What is the NPV for this project? (Round your final answer to the nearest dollar amount. Omit the "$" sign and commas in your response.
