Based on the cashflow from the investment per year, the initial investment, and the working capital, the project's IRR will be 18.48%.
First find the After-tax salvage value:
= 171,000 x ( 1 - 40%)
= $102,600
Year 1 cashflow:
= -583,000 - 39,500 working capital
= -$622,500
Year 6 cashflow:
= Working capital + Project cashflow + After-tax salvage value
= 39,500 + 165,300 + 102,600
= $307,400
Using a Spreadsheet, the IRR is:
= 18.48%.
