Given the following attributes of an investment project with a five-year life and an after-tax discount rate of 12%, calculate the net present value (NPV) and the payback period of the project: investment outlay, year 0, $8, 920; after-tax cash inflows, year 1, $940; year 2, $1, 080; year 3, $3, 300; year 4, $3, 600; and year 5, $5,000. (Use the built-in function of Excel to estimate the NPV of this project.) (Negative amounts should be entered with a minus sign. Round your answers to the nearest whole dollar amount.)
