Purchase price of a new machine is $84000 and the useful life of the machine is 6 years. At the end of 6 years salvage value of the machine is zero. Before tax earnings from the new machine is $18000 per year. The effective income tax rate is 40% and after tax MARR is 12% using the SL depreciation, show the before-tax and after-tax cash flows in a table and calculate after-tax IRR value for this investment. Is this a good investment?
Since annual earning is $18000, before tax cash flow = $18000
Annual Depreciation = Cost/ Useful Life = 84000/6 = $14000
Net Profit Before Tax = Earnings - Depreciation = 18000-14000=$4000
Tax =40%*4000=$1600
Profit After Tax = Profit Before Tax - Tax =4000-1600 = $2400
After tax cash flow = Profit after tax + depreciation = 2400+14000=$16400
Hence cashflows can be tabulated as below:
Year 0 | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | Year 6 | |
Before Tax cash flows | -84000 | 18000 | 18000 | 18000 | 18000 | 18000 | 18000 |
After Tax cash flows | -84000 | 16400 | 16400 | 16400 | 16400 | 16400 | 16400 |
Since after tax IRR is 4.72% which is less than MARR of 12%, it is not a good investment
