Eb's Eggs just bought a new egg sorting machine for $106,944. The machine will save $32,760 in year 1, $34,255 in year 2, $18,724 in year 3, and $8,568 per year from year 4 until the machine is salvaged at the end of year 11. At the end of year 11 it will have a salvage value of $2,110. Eb uses a MARR of 7% to make decisions. What is the payback period (PBP) for this machine?

11 8568 0.4751 4070.66 10638.36

PBP = 8 + |-2447.55| / 4660.14

        = 8 + (2447.55 / 4660.14)

        = 8 + 0.52

        = 8.52 years

Thus, the payback period (PBP) for this machine is 8.52 years.

A company bought a new machine fot $300,000. The new machine generated revenue for $90,000 per year. Operating cost of that machine is $10,000 per year. The machine is depreciated according to 7-years MACRS method. The machine is sold for $80,000 in the middle of 6th year of service. Determine the after tax net present worth. Assume, the after-tax MARR is 10% and income tax rate is 25% (federal and state combined).
