Consider an investment of $500,000 at time zero for machinery and equipment to be depreciated using 8 year straight line depreciation starting in year 1 to year 8. Annual revenue is estimated to be $380,000 and annual operating costs of $160,000. $200,000 for working capital investment is also needed at time zero and working capital return is expected to equal the initial working capital investment at the end of the project (8th year). Salvage value of the machinery and equipment is expected to be zero. The minimum DCFROR is 12% and the effective income tax rate is 35%. Calculate DCFROR and NPV project life.
